INSTALLATION AND CONNECTIONS6.1 Environmental requirementsThe inputs and outputs of the AL20AN CPU board are isloated in group and theisolation of the inputs on expansion boards and DIN modules depends onconstruction of board. More information of isolation in following chapters. Theserial connectors RS232 and parallel with it RS485 (SER2) and RS232 (SER1)are not isolated from PLC’s internal voltages. To ensure proper function ofAL20AN the installation circumstances must be carefully considered.Operating temperature + 5 to + 45°CMoisture, corrosive gases, liquids and conductive dust must not be presentwhere PLC boards are installed.The PLC boards don't resist heavy vibration very well.The distance from electromagnetic field generating devices, such as electricmotors, switch gear, thyristors, welding equipment, switched power suppliesand power converters/inverters must be adequate.PLC boards are quite immune against powerfull light sources.If some item above or any other envinronmental feature may cause errors to PLCfunction it is advisable to install the PLC in the steel plate enclosure. It is also advisableto install possible auxiliary input/output relays fuses and power units intheir own enclosure near the PLC. All the contactors connected to PLC have to beequipped with RC protection devices and the 24 VDC control relays withextinguish diodes.6.2 Field wiring6.2.1 Earthing/groundingThe metal parts of the PLC enclosure must be connected to the plant’s logicground.6.2.2 Power supply connectionsNormally no functional grounding is necessary when 24 volt floating voltagesystem is used with the PLC’s power supply connection. It is important that the 24volt wiring is carefully kept isolated from ground level and 230 volt supply voltages.The CPU board, AL20AN receives the +24 V DC supply voltage from an external,isolated power supply unit (such as 24VDC /1.2A or 24VDC /2.5A). The controllerconverts this to the voltages it requires.FF-Automation Oy

Input board DI16 and the input part of theboard RIO8 doesn’t need any external power supplies. The control/operatingpower for the controlled loads must be taken from external supply units.6.2.3 Digital inputsThe digital inputs are isolated in group on AL20AN CPU board. Externallypowered potential free contacts or PNP type inductive/capacitive sensors may beconnected to PLC. The supply voltage for the PNP sensors is normally taken fromexternal I/O power unit.It is recommended to use twisted pair shielded cables in input wiring. The cablingshould be installed separately from the 230/400 VAC power cabling. The cableshields may be connected to logic ground only at one point, normally at the end onthe PLC enclosure. If there is heavy electromagnetic disturbance, the PLC’sunisolated inputs can be isolated from field equipment with relays oroptoelectronic modules.Look at chapter 6.3.3.6.2.4 Digital outputsThe digital outputs are isolated in group on AL20AN CPU board and on DO32expansion board. Only low powered 24VDC control relays, LED indicating lights or24 volt indicating lights may be connected to the outputs. The supply voltage forloads is taken from external I/O power unit.It is recommended to use twisted pair shielded cables in output wiring. The cablingshould be installed separately from the 230/400 VAC power cabling. The cableshields may be connected to logic ground only at one point, normally at the end onthe PLC enclosure. If there is heavy electromagnetic disturbances, the PLC’sisolated outputs can be double isolated from field equipmnet with relays oroptoelectronic modules. Look at chapter 6.3.3.6.2.5 Analog inputs/outputsThe analog inputs and outputs are unisolated in AL20AN CPU board and inEXA8/4 expansion board. If active transducers are used, it should be checked thatthe output circuits of the transducers are galvanically isolated from it’s supplyvoltages. If you can’t be sure of isolation, it is advisable to furnish the transducerwith an external galvanic isolator. The supply power for passive transducer isnormally taken from PLC’s power unit. The impedance of AL20AN PLC’s analogmilliamper input is 46Ω.It is recommended to use twisted pair shielded cables in output wiring. The cablingshould be installed separately from the 230/400 VAC power cabling. The cableshields may be connected to logic ground only at one point, normally at the end onthe PLC enclosure.RMS analog input modules requires 12 VDC power to function.

CONTROLLERS9.1 Register Variables of ControllersThe AL20AN PLC’s system software includes 32 12-bit direct digital controllers (DDC)with PID charasteristics. The controller parameters are held in 16-bit W GM memoriesand in 8-bit register outputs (R O).The number of used controllers per group is given in the register outputs (R O 128 -R O 131). This number also determines the group update interval depending on thenumber of controllers used. If one controller in a group is updated, the update time is100 ms. Similarly, if two controllers in a group are updated, the update time interval is200 ms. Maximum update interval is 25500 ms, or 25.5 seconds.If in PLC’s application program the update interval is not defined the default updateinterval of 500 ms is used (R O 128 - R O 131 = 5).Controller numberR O numberGroup 1Group 2Group 3Group 4081624191725210182631119274122028513212961422307152331R O 128R O 129R O 130R O 131Example: If it is desired that three controllers update interval is100 ms and twocontrollers 500 ms, parameters should be set as followsGroup 1 - desired update interval is 100 ms, then R O 128 = 1Group 2 - desired update interval is 100 ms, then R O 129 = 1Group 3 - desired update interval is 100 ms, then R O 130 = 1Group 4 - desired update interval is 500 ms, then R O 131 = 5Controllers operating mode is given in 16-bit variables (W GM 0, 8, 16 etc.).

If the derivative time constant is given as0 the term is not used.I term controls how quickly the process reacts to stabilise offset error. The integrationtime constant is a 16-bit parameter and is given in hundreds of millisconds (0.1-6553.5s). The larger the integration time constant the slower the process reacts tooffset errors.

If the integration time, I is too short, anoscillation of the type shown in the right-hand figure will occur.Effect of the derivative time constant, DThe effect of the derivative time is critical, as illustrated in the figures below.

AutoLog 20AN Instruction ManualPage 9 - 529/12/20069.4 Controller tuningIn a control system suitable values must be found for the control parameters P,I and D.Suitable parameters can be determined using mathematics or a Bode diagram,however, these methods can be time consuming. Controllers are usually tuned on thebasis of experimental data from the control system.Two simple and effective methods for this are described below:- Step response method:The delay and rise time of the step response of the process are determined, and thecontroller settings are calculated on that basis.U(t)UotT t U 0P Controller: U P = = cT s Y 0Y(t)YoTtTstPI Controller : U P = 1.25 cT I = 3 T tPID Controller : U P = 1.25 cT I = 3 T tT D = 0.42 T t- Oscillation method:The gain and oscillation cycle time at the point of oscillation are determined, and thecontroller settings are calculated on that basis.P Controller:PI Controller:PID Controller:K P = 0.5 K PcrK P = 0.455 K PcrT I = 0.85T crK P = 0.6 K PcrT I = 0.5T crT D = 0.12T crK P =1U P= gainT I = Integration time constantT D = Differentiation time constantK Pcr = Critical gain at which the processoscillatesT cr = Cycle time of process oscillationThe above two methods yield reasonable starting points for the controller parameterswhich can be further refined during operation.

Page 9 - 629/12/2006AutoLog 20AN Instruction ManualA typical application, controlling the temperature of the circulating water in a centralheating system, is shown below.The mixing valve is controlled by a pulse driven actuator motor. The dead time in anapplication of this kind can be several seconds., as changes in the water temperaturewill not immediately be detected by the sensor. It is, therefore, futile to give further drivepulses to the valve before the true effect of the previous action is known. This deadtime can be accounted for when tuning the controller using the step response method.Example Temperature control of circulating water by 3-point control.Setpoint value W I 001Actual value W I 000Mixing valveCON302CON301CON303SW1CON101H108H107H106H105H104H103H102H101BoilerMOD6MOD4IC3IC4MOD7MOD5MOD3MOD2MOD1MOD0IC1IC2IC10RX TXRX 12VRUNH201H202H208H207H206H205H204H203SER2CON501SER1CON1TXEXTI 2 C IC2B1CON201CON502CON503J1 J2 CON403CON401CON402O 1 'close'O 0 'open'Logic program for water heating:STR R C 010 ; Control interval is defined toEQ R O 128 ; 1 second (10*100 ms)STR W C 050 ; Integration time (50 * 0.1s) ( 0 - 65535)EQ W GM 012 ; greater value gives slower actionSTR W C 002 ; Differentiation time (2 * 0.1s) ( 0 - 255)EQ W GM 011 ; greater value gives bigger stepsSTR W C 500 ; Gain P = (100/500) P=0.2EQ W GM 013 ; greater value gives slower actionSTR W I 001 ; Set point, e.g. from potentiometerEQ W GM 010STR W I 000 ; Actual value from temperature sensorEQ W GM 009STR W C 001 ; Controller in automatic modeEQ W GM 008STR R C 010 ; Pulse interval 1sEQ R O 132STR R O 140 ; Read 'open' bitsBIT M 020 ; Convert to bits (controllers 0 - 7)STR M 021 ; Use bit for controller 1EQ O 001 ; to open valveSTR R O 136 ; Read 'close' bitsBIT M 020 ; Convert to bitsSTR M 021 ; Use bit for controller 1EQ O 002 ; to close valveFF-Automation Oy

ATDP 90-844992.The modem reports a connection using the "CONNECT" response. For the specificformat of ‘AT’ instructions, consult the modem manual.Data transfer rates of over 1200 baud, using telephone lines, can result in frequenterrors. If PRT instructions are used to transfer data, error correcting modems shouldbe used as data transfer errors may lead to operational problems.

The eventsimmediately after switching on and in response to supply voltage variations aredescribed below.Voltage, U+32 V+24 V(b+20 V+16 V+14 V(c+8 V1. 2. 3. 4.5.(aTime, s1. The PLC is in ShutDown state (no function is detected).2. The chopper circuit starts -> the supply voltage is converted to a +5V regulated supply for thelogic processor and the rest of electronics.The POWFAIL signal from the voltage monitor is active and the RESET signal is active.3. The POWFAIL and RESET signals are deactivated. The logic processor does not start regularprogram execution until POWFAIL has been inactive for at least 600 ms.4. The Programmable Logic Controller operates normally.If the supply voltage falls below + 16 V for any reason, the PLC responds as follows:5. The POWFAIL signal is activated. The logic processor suspends normal operation and awaits thereturn of the supply voltage, the POWFAIL counter (R O 241) is incremented by 1.a) The supply voltage falls below + 14 V.The Reset signal stops the processor and protects the memory circuits.b) The supply voltage falls below + 16 V and rises again to a value above + 17,5 V within less than20 ms.The logic processor resumes program execution. Power fail counter R O 241 is incrementedby 1 to indicate a brief power interruption. The indicator light on the CPU boardflashes at a combined slow (=0,5Hz) and fast (= 5 Hz) rate for 4 minutes.c) The supply voltage falls below + 16 V but not below + 14 V and rises again to a value above+ 17,5 V within a longer time than 20 ms.The logic processor stops program execution, all outputs of the PLC are cleared,and logic processor flashes the indicator light at a very fast rate while awaiting the returnof supply power. When the supply voltage again rises, the logic processor resumes programexecution in the same way as after an ordinary switch-on, but flashes the indicator light at acombined slow and fast rate for 4 minutes.FF-Automation Oy

Page 11 - 229/12/2006AutoLog 20AN Instruction Manual11.2 Start of program executionWhen the PLC is started, bit memories (M,BM,GM 0-95 and 192-255), bit outputs (0-95and 192-255) and step registers (0-7) are cleared.If the position of the switch SW1 DIP 5 on the board is on, bit memories (96-191), bitoutputs (96-191), timers, counters and step registers (8 -31), register memories, wordvariables, FIFO and shift registers are also clered.Next the logic program stored in an FLASH memory is transferred to RAM.The logic program is checked and any error messages are sent to the programmingdevice. If the program is OK, it starts.After the second program cycle the logic processor examines those register variablesthrough which the logic program can tell:- what the serial interface is to be used, if not for programming- the baud rate of the serial interface, if not defined by the switches- the language selection, English or FinnishAll kinds of communication in the PLC (computer, user terminal, modbus) can commenceafter the second program cycle.The bit accumulator of the PLC is set to one during the two first program cycles, after thatit is always zero at the beginning of program cycle.In the beginning of the every program cycle the register accumulator holds the value ofprogram cycle time in milliseconds ( resolution 5 ms)11.3 START commandWhen program execution is initiated with the START command from the programming devise, thefollowing takes place:- the states of outputs and memories remain unchanged- the logic program is transferred from RAM to FLASH memory- The logic program is checked, and started if it is OK.- after the second program cycle the parameters are read fromthe register variables.FF-Automation Oy

AutoLog 20AN Instruction Manual Page 11 - 329/12/200611.4 Remedies to common problemsProblems with communication of the programming device and the PLC:- Set the DIP switch 2 of the SW1 to position 0 (OFF).- Set the baud rates of the programming device and the PLC to the same values with DIPswitches 3 and 4 of SW1.- Check the type of the interconnection cable.- If the programming device is an IBM PC or equivalent, the correct programming software isALProWin or ALPro- When using the ALPro software, remember to keep the CAPS-LOCK on.- Check the operation of serial communication by pressing CLR (N) in terminal mode.One program line or an error message must appear on the screen.- Check that the correct serial port is used in PC (COM1/COM2)- Check that the supply power for the programming device is taken as far as possible from thesame outlet/phase/fuse as for the PLC.Switch off both the PLC and the PC for a moment and restart them.FF-Automation Oy

AutoLog 20AN Instruction Manual Page 12 - 129/12/200612. PROGRAMMING(Paragraph 12.1 discusses the available alternative programming methods. Since separatedocumentation is provided for the programming programs, they are only briefly outlined below.)12.1 Programming methodsThe programming device can be any IBM compatible PC computer. The program istransferred through the programming cable to the PLC. When programming with a PC,the AlPro programming software is used. With the programming software, the PLCprogram can be written either in OFF LINE mode (without a PLC, forsubsequent transfer) or in ON LINE mode (the program is immediately transferred to thePLC).The AL 14 series Programmable Logic Controller incorporates a programming portSer1, (information on the operation of instructions and commands) and an RS-232Cinterface. Accordingly, the following alternative programming methods are available:- the ALProWin programming software- the ALPro programming software- a PROM programmerA complete program for the PLC can be produced using the programming softwareALProWin or ALPro, which run on a personal computer. The programming software alsoallows for off-line programming and versatile program documentation etc.Memories of the PLC and programs:When a program is transferred from a programming device to the PLC, the program first goes toRAM and, after completion of the START command, to FLASH memory. When a logic program istransferred from the PLC to a programming device, the program is first stored from RAM to FLASH,and then transferred to the programming device.The logic program is stored in a FLASH memory. When power is applied to the Programmable LogicController, the program is read into RAM for execution.12.1.1 Programming with a PROM programmerWhen a number of PLCs with identical functions are required, programming iseasiest to do by duplication. First program one FLASH using one of theprogramming programs or a terminal and then copy the finished program into theprogram memories of the remaining PLCs with a FLASH programmer.FF-Automation Oy

Page 12 - 229/12/2006AutoLog 20AN Instruction Manual12.1.2 Programming with ALProWin/ALProThe program, with comments, is first written in plain text form using the text editor ofALProWin. (Any other text editor producing ASCII text will do just as well.) The programis then compiled with ALProWin compiler into a form that the Programmable LogicController understands, stored on a diskette, and transferred into the memory of thePLC when desired.Further features of ALProWin:• Macros: Emphasizing the program structure. (Page division, writing similar programsections, etc.)Windowing: Error messages easy to include in the listing file.• ON-LINE features including display of variables, history display, on-line editor, etc.For example, the basic displays can be stored on disk, which facilitates the clearing offault conditions.• ALProWin contains HELP screens describing the functions.• Available in Finnish and English language versions.A free version of the program, ALProWin-demo or ALPro-demo, is also available (similarto ALProWin / ALPro proper, but the length of the program that can be written is limited)as well as a manual (ALProWin / ALPro Programming manual).12.1.3 Fast program loopA fast program loop can be written into the Programmable Logic Controller for executionat timer interrupts, at intervals of 5 ms. The executable program of the loop starts asprogram line 0000 and ends at an END instruction.When the fast program loop is in use, the PLC reads inputs 0 - 7 and writes to outputs0 - 7 every time before executing the fast loop.The differentiation of auxiliary memories 0 - 7 is timed by the fast loop.The maximum permissible length of the fast loop is 62 instructions, but it is advisable tokeep it as short as possible in order to avoid slowing down the main program more thannecessary.No PRT instructions are allowed in the fast loop.CAUTION! The END instruction must not be written while program execution is inprogress. The program must always be halted when instructions preceding the ENDinstruction are deleted, added, or changed.FF-Automation Oy

It is possible to write subroutine programswhich start with the SBR n command (n is subroutine number), and ends with the RET command.The maximum number of subroutines is 32 (numbers 0 - 31). The STOP command must be appearafter the subroutines, this ends the PLC program. The PLC system program ignores all SBR and RETinstructions which appear before STP instruction. If the RET instruction is missing from a subroutinethe PLC executes the next subroutine(s) until the a RET command is found. If no RET command isfound, program executes until the STOP command is reached, and the PLC system program doesnot return to main program. The PLC now performs I/O updates and the main program starts againfrom line 1. Therefore the main program is executed only up to the first CSR instruction, the rest ofthe main program is not executed at all. If there is a CSR call for a subroutine that does not exist, thePLC interpretes the CSR instruction as a NOP instructionand continues normally.• STPOperationThe PLC's main program ends with this command and all subroutine programsmust be written after the STP command• CSR nOperationAffectedThe PLC executes the subprogram n if the bit accumulator is trueBit accumulator Register accumulator Word accumulator VariableThe states of the accumulators remain unchanged, so subroutine can use theaccumulator states.• SBR nOperationThis is the starting instruction of a subroutine• RETOperationAffectedExampleThe subroutine ends here, execution is then returned to main program.Bit accumulator Register accumulator Word accumulator VariableThe states of the accumulators remain unchanged, so main program can use theaccumulator states after executing the subroutine.Scaling subroutine for analogue variables.

Page 12-5229/12/2006AutoLog AN Instruction ManualThe programming software reacts to an incorrect key operation with a tone signal(for example, WRITE before the instruction is complete). Keying mistakes can becorrected with the CLR (N) key.Normally the PLC’s application program runs all the time. If changes are to be made tothe program, it is advisable to halt it with the STOP key while making the changes. Theprogram is started with the START key. The STOP and HIN commands halt execution ofthe program. The WRITE, INS, DEL, LIST, FIND, and HOUT commands halts executionuntil the function has been carried out.Program changes made with the programming device (WRITE, INS, READ/DEL) arequick, because they only affect the RAM memory. The logic program in RAM is storedinto EEPROM memory when the START (!) key is pressed.The fast program loop must be changed only when execution of PLC program isstopped.12.6 Programming pointerThe programming software keeps track of the address of the program memory locationcurrently affected by programming operations (the programming pointer). Theprogramming pointer can be located by pressing the CLR key (the program address, i.e.the program line number, and the instruction will be displayed). If there is no AutoLoginstruction at this address, the 'ERROR 010' message is given.The address can be changed by typing a new address or by stepping forwards orbackwards in the program. The address is also automatically updated when aninstruction is written into memory or deleted.The ADDR key moves the cursor to the start of the desired program line. The programline number is entered as five octal digits (0 - 7), whereupon the programming softwaredisplays the instruction at the address given, or gives an error message to indicate thatthere is no instruction on the program line specified.The NEXT key and the PREV (Previous) key move the programming pointer in eitherdirection, one program line at a time. However, when stepping backwards, the pointer ismoved back far enough so that a real instruction is found. If the pointer is at a two-byteinstruction, the correct pointer movement takes place automatically.FF-Automation Oy

AutoLog 20AN Instruction ManualPage 12-5329/12/200612.7 Entering an instruction in memory by terminal programmingTo enter a new instruction in the program at the location indicated by the programmingpointer, first key in the instruction and then press either WRITE or INS. Example:Text displayedCommentsPress CLR (N).0002 EQ O 000 A new instruction is to be entered here.0002 EQ O 000 STR First key STR (A).0002 EQ O 000 STR I Then the variable name I (Q).0002 EQ O 000 STR I 000 Then the variable number, first 0.0002 EQ O 000 STR I 000 The second and third 0. The instruction is now completeand is entered in program memory with the WRITE key (X).0003 STR M 000 The instruction on the next program line is displayed.If the INS key had been used in the above example instead of the WRITE key, thedisplay would have been as follows:0002 EQ O 000 STR I 000 Now press the INS key (C).0003 EQ O 000 The instruction that was previously on program line 2, hasbeen pushed onwards to line 3, and the new instruction hasbeen written on line 2.If an attempt was made to enter a non-existent variable number into an instruction, theprogramming program of the PLC immediately issues an 'ERROR 030' message anddisplays the program line.If the new and the old instruction differ in length in the case of the WRITE command, andalways when the INS command is used, the programming software moves theinstructions on subsequent lines of the program forwards or backwards as required. TheSTOP instruction is always the last instruction to be shifted.If an attempt was made to enter an instruction when the programming space is alreadyfull, an 'ERROR 050' message is issued. The error is cancelled as soon as a sufficientnumber of instructions are deleted from the program.12.8 Deleting an instruction from memoryTo delete instructions from the program, use the DEL command (M). First place theprogramming pointer at the instruction to be deleted and then press the READ key (V).The DEL command will now delete the instruction in question and move back allsubsequent instructions as far as the STOP instruction, to fill the gap left by the deletedinstruction.Example:ext displayed Comments0010 AND I 000 Keys pressed: ADDR (Z),0,0,1,0.0010 AND I 000AND I 000READ key (V) pressed.0010 EQ O 000 DEL key (M) pressed. The instruction AND I 000 was deleted fromprogram memory and the remaining instructions were moved back one position.FF-Automation Oy

Page 12-5429/12/2006AutoLog AN Instruction Manual12.9 Locating an instruction in a program by terminal programmingFIND command [ ( ] searches for a given instruction, starting at the programming pointer.If the instruction is not found before the STOP instruction is encountered, an 'ERROR040' message is issued. Place the programming pointer at the desired point, enter thedesired instruction in its entirety (in the case of timer and counter setting instructions, thesetting value must also be given, although the FIND command does not make use of it).When the instruction is complete, press the FIND key; the programming software willdisplay the next point of occurrence of the instruction and the instruction itself. If the FINDkey is pressed before the instruction is complete, the PLC does not accept the command,and issues a short tone signal to indicate the error.12.10 Listing the program by terminal programmingIf a program listing is desired, either on the display or on paper, move the programmingpointer to the desired starting point and press the LIST key [&]. The programmingprogram will output the program in mnemonic format up to the STOP instruction. Outputcan be stopped by hitting the space bar [ ]. (The programming pointer will not be movedaway from the starting point by the LIST operation.)12.11 Storing the program by terminal programmingA program written into the program memory of the AutoLog 20AN can be stored onto anexternal device for later requirements. The HOUT command [%] causes the program tobe stored from the RAM program memory to EEPROM memory, whereupon it is sent tothe serial line in Intel hexadecimal format.The HIN command [^] causes a logic program in Intel hexadecimal format to be read intothe PLC, where it is first stored in RAM; when the entire program has been received, theprogramming program stores the program into EEPROM memory. This may take a littlewhile.12.12 If there is no AutoLog program in memoryIf there is no logic program, the programming program reports this by issuing an 'ERROR010' message, and the indicator light on the CPU board flashes at a fast rate (5 Hz). Thefast flash means that there is no STOP instruction in the program, or that there is anunidentifiable instruction ahead of the STOP instruction. Rectify the program and start itwith the START command [!]. If the program is formally correct, it will start, and theindicator light changes to the normal flashing rate (0.5 Hz).If the STOP instruction in a program is overwritten while the program is running, the PLCno longer operates properly (unless there happened to be two successive STOPinstructions in program memory). This condition can be remedied by switching the PLCoff and back on again. Since no STOP instruction can be found in memory, theprogramming pointer will now stop at the first program line where no AL20AN instructionis found. Enter a STOP instruction on this line.FF-Automation Oy

AutoLog 20AN Instruction ManualPage 12-5529/12/2006To clear the entire program space, write a STOP instruction on program line 0000. ThisSTOP instruction will overwrite the first instruction of the old program (the remainingprogram lines are still intact), and the new program can now be written over the old one.12.13 Monitoring the operation of a program by terminal programmingWhen the DISP key [ ) ] is pressed, the cursor moves to the beginning of the next lineand awaits entry of a variable name and number. As soon as these are given, the state ofthe variable is displayed, as well as a dash [-] if it is possible to alter the variable. TheDISP operation is provided to allow variables to be monitored and changed.The variablecan be redisplayed with the RETURN key. To alter the variable, key in the new value (0or 1 for binary variables, a three-digit decimal number 000 - 255 for register variables).12.13.1 Monitoring register and word variablesTo select a register variable, press TAB (CONTROL-I) followed by the variable name andits number with three digits. To select a word variable, press TAB (CONTROL-I) twice,followed by the variable name and its number with three digits.R -> W -> R = 12.13.2 Monitoring timers and countersIn the case of timers and counters, two numbers are displayed after the variable number:the current content of the timer/counter (first), and its setting. If the value of a timer/counter is changed, the change affects the setting, not the current value. If the setting iszero, the logic program, when executing a Load instruction LOAD T or LOAD C, entersthe value in the program as the current value. If the setting is non-zero, the setting isentered as the current value of the timer/counter. Switch SW1 selects whether settingvalues are retained during a power failure. Example:Key pressed Command Display) DISP Cursor to start of new line.TAB R R Select a register variable.I T R T Select a timer.0 R T 0 Enter number0 R T 00 of timer.0 R T 000 = 100 225- Remaining time 100 * 10 ms.RETURN = 085 225- Now remaining 85 * 10 ms.1 = 085 225-1 Enter 150 as5 = 085 225-15 new0 = 085 225-150 setting.To check a sequence register, press the DISP key [ ) ] followed by R (TAB) and S [?] tosee the step at which the sequence register in question is and how long it has been atthat step. If a new step number (000 - 255) is now entered, the sequence register inquestion will move to that step and the time will be reset.FF-Automation Oy

The executable program of the loop starts asprogram line 0000 and ends at an END instruction.When the fast program loop is in use, the PLC reads inputs 0 - 7 and writes to outputs 0 -7 every time before executing the fast loop.The differentiation of auxiliary memories 0 - 7 is timed by the fast loop.The maximum permissible length of the fast loop is 62 instructions, but it is advisable tokeep it as short as possible in order to avoid slowing down the main program more thannecessary.No PRT instructions are allowed in the fast loop.CAUTION!

ADJUSTMENT OF ANALOG INPUTSAL20AN PLC CPU card has 8 analog inputs and these are adjusted at the factoryaccording the order definings. The measured signal type is selected individually forevery input and the hardware adjustment is made by connection module. The resolutionof the analog inputs are 12 bits.In case you need to change the input measurement module to another, you mustchange the analog input module which corresponds to the desired input signal and theinput must be readjusted. Also in the case you need to change the scaling of an analoginput within the existing range or you need readjust the analog input, a softwarecommand has to executed via ALPro programming software. The adjustment takesplace using the register outputs of the PLC (like in an AL2000).RegisteroutputMeaning ofvariableR O 220 Adjustment step 0 ... 5R O 222 Input number to be adjusted 0 ... 7Min / max.values8 bit 16 bitCalculation of the valuefor adjustment variablesR O 224 Lower adjustment value high byte 0 ... 15 (0 ... 4000) 500 = 1 * 256 +R O 225 Lower adjustment value low byte 0 ... 255 244R O 226 Upper adjustment value high byte 0 .... 15 (0 ... 4000) 3500 = 13 * 256 +R O 227 Upper adjustment value low byte 0 ... 255 172The initialization of adjustment step is made through register ouput R O 220.The permitted adjustment steps are:Before step 1 both calibration values can be inserted (R O’s 224, 225, 226, 227)Step 1: Start adjustmentStep 2: Set the lower adjustment value for the inputBefore going to step 3 the lower calibration value must be insertedStep 3: Read the lower adjustment valueStep 4: Set the upper adjustment value for the inputBefore going to step 5 the upper calibration value must be insertedStep 5: Read the upper adjustment valueAS the result of succesful/unsuccesful adjustment of input PLC’s system program writesinto register output R O 220 the result value:0 adjustment was succesfuln > 5 error codeFF-Automation Oy

The value can be seen in the PLC as a number from 0 to 4096 (as a rawvalue).16.1 What is needed for adjustmentYou need the ALPro or ALProWin software, a PC, an accurate mA-meter, an accurateV-meter, an adjustable resistance reference and when adjusting current inputsmillamper source.For making the readings of the analog inputs you have to use the PC and the ALProsoftware. For the adjustment of the analog inputs of AL20AN CPU only one instructionhas to be downloaded to the PLC; the STOP instruction. Through the ALPro debug(watch table) function you can see the values of all AL20AN’s analog inputs.How to read the input values using the PC and ALPro1. Connect the AL20AN to the PC and start the ALPro software.2. If you want to read inputs in values from 0 to 1000, write the following program,otherwise you see the values from 0 to 4000.STR W I 000 This program was made for the analog input 0. If youDIV W C 004 want to include all analogue inputs at once, you canEQ W M 000 add similar instructions for all the rest of theSTOPanalog inputs3. Compile program by choosing Compile from the main menu.4. Transfer the program to the PLC by choosing Write prog to PLC from theTransfer submenu5. Choose Debug from the Online submenu.6. Choose Start/Stop from the Debug main menu.7. Start the program execution by Start F7 command from Start/Stop submenu.Now you have started the execution of the program you have written before.Check that the status light is blinking indicating normal operation.8.

When adjusting analog input 0insert number 0 into R O 222 = 0.Other inputs must be adjusted withcorresponding numbers in R O 222.I +121The adjustment of an analog input is made as follows:1. Start the adjustment by setting number one (1) to R O 220. The adjustment program moves to step two (2) and waits you to insert the loweradjustment values into R O 224 and R O 225.2. Adjust the level of the analog signal to lower adjustment value.In order to make the adjustment of the Pt100 input as accurate asbossible over the measurement range, it is advisable to take the lowervalue about +10% higher than minimum measure value. This due to nonlinearity of Pt100 sensor.3. When the signal value corresponding to the lower adjustment value canbe read on ALPro’s debug screen, set into R O 220 a value of three (3).Now the adjustment program reads the signal value and moves to stepfour (4) to insertion of the upper adjustment value into register outputsR O 226 and R O 227.4. When the signal value corresponding to the upper adjustment valuecan be read on ALPro’s debug screen, set into R O 220 a value of five(5). Now the adjustment program reads the signal value, calculates thevalues of the adjustment parameters and saves the values to theFLASH memory. After that the adjustment program informs the user ifthe adjustment was succesful by writing into R O 220 the value zero(0), or if the result was unsuccesfull the error code. From the errorcodes the user can check what the problem was.FF-Automation Oy

Insteadof adjusting the OFFSET at the lowestvalue we use a 10% point as theadjustment point for the low end of themeasurement range. In the same way weuse the 90% point as the adjustment pointfor the high value. This increases theoverall accuray.The curve in picture is exaggerated.FF-Automation Oy
