Operator Control and Monitoring DevicesMicro panelsTD 200C Text Display2■ Overview• The user-friendly text display for the S7-200 with customizabledisplay• For control and monitoring:Message text display, intervention in PLC program, setting ofinputs and outputs• Direct connection to CPU interface using supplied cable orincorporation into network (also via EM 277)• No separate power supply required• No separate parameterization software required• Frontpanel design can be individually selected• Addressing and setting of contrast in supplied menu■ ApplicationThe TD 200C text display is the optimum solution for all HMItasks with SIMATIC S7-200. Individual printing of the surface ofthe device enables it to be perfectly matched to the applicationenvironment.It supports:• Display of message texts• Operator actions in the control program, e.g., modification ofsetpoints• Setting of inputs and outputs, e.g., for switching a motor onand off■ DesignThe TD 200C is simply connected to the PPI interface of theS7-200 using the supplied connecting cable. A separate powersupply is not required. It is also possible to connect severalTD 200C to one S7-200.The TD 200 features:• Rugged plastics housing with degree of protection IP65 (front):Increased watertightness due to absence of slots for labelingstrips.• Mounting depth 27 mm:The TD 200C can be mounted without additional accessories incontrol cabinets or operator panels, or used as a handheld unit.• Backlit LC display;readable even under unfavorable lighting.• Integrated interface for connection of cable.• Connection for optional power supply:A power supply unit is required if the distance between theTD 200C and S7-200 is more than 2.5 m. PROFIBUS cables arethen available instead of the connection cable.• Individually designable user interface:The control elements of the front of the device as well as thedesign can be configured individually on a printable sheet. TheKeypad Designer (a component of STEP 7-Micro/WIN) is usedfor configuration.■ FunctionThe TD 200C permits:• Display of message texts:up to 80 message texts (alarms) with max. 6 variables displaycurrent operating states and can be optionally parameterizedto require acknowledgment and can be additionally protectedby a password. Also up to 64 static alarms with up to 6 variablescan be configured. System texts are stored in English,German, French, Spanish and Italian in the unit. Various charactersets can be selected, and messages can be additionallysaved in the simplified Chinese character set.• Display and modification of process parameters:process parameters are output on the display, and can bemodified using the input keys, e.g. for temperature settings ormodifications to speed.• Setting of inputs and outputs:a bit memory is assigned to each of the programmable functionkeys. These can then be set during operation, e.g. during commissioning,testing and diagnostics. It is then possible e.g. tocontrol motors without having to install additional control elementsin the system.• Additional functions and features:e.g. processing of floating-point numbers, symbols for bargraphdisplay, various data blocks for operation of several TDson one CPU, password protection for integral SETUP menu andmodified variables.• Activation of TD 200 editing mode by PLC:Variables embedded in messages can be edited directlywithout having to press the Enter key or to place the cursor atthe variable.• Setting a PLC bit:- Set bit:When a function key is pressed, a bit is set in the PLC.This must be reset by the user program.- Momentary:A bit is set when pressing a function key, and deleted againwhen the key is released.• New character set (Greek, Latin2, Turkish) to support furtherforeign languages.• Programming the S7-200 memory module.• Selection of operating mode of the CPU (RUN/STOP).• Editing the V memory area.ProgrammingThe configuration data of the TD 200C are saved in the CPU ofthe S7-200. The message text strings and configuration parametersare created with the STEP 7 Micro/WIN V4 programmingsoftware. Additional parameterization software is not required.The Keypad Designer (a component of STEP 7-Micro/WIN V4) isused to configure the operating front design.Special data areas are reserved in the CPU of the S7-200 fordata exchange with the TD 200C. The TD 200C directly accessesthe respectively required functions of the CPU via thesedata areas. A separate TD 200 wizard in STEP 7 Micro/WIN V4supports user-friendly parameter assignment.2/18Siemens ST 80 · 2006
