Operator Control and Monitoring DevicesMicro panelsTD 200 Text Display2■ Overview• The user-friendly text display for the S7-200• 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• Addressing and setting of contrast in supplied menu■ ApplicationThe TD 200 text display is the optimum solution for all HMI taskswith SIMATIC S7-200.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 on andoff■ DesignThe TD 200 is simply connected to the PPI interface of theS7-200 using the cable supplied. A separate power supply is notrequired. It is also possible to connect several TD 200 displaysto 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 200 can be mounted without additional accessories incontrol cabinets or operator panels, or used as a handheldunit.•Backlit LCD;easy to read even under poor lighting conditions• User-friendly layout of input keys,some of which are programmable function keys• Integrated interface for connection of cable• Connection for optional power supply:a power supply unit is required if the distance between theTD 200 and S7-200 is more than 2.5 m. PROFIBUS bus cablesare then available instead of the connection cable.• User-specific labeling strips:It is necessary to remove the rear of the housing before fittingthe labeling strips. Therefore, please fit the strips before installingthe device.■ FunctionThe TD 200 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 memory bit is assigned to each of the 8 programmable functionkeys. These can then be set during operation, e.g. duringcommissioning, testing and diagnostics. It is then possible e.g.to control motors without having to install additional controlelements in the system.• Additional functions and features:e.g. processing of floating-point numbers, symbols for bargraph display, various data blocks for operation of severalTD 200 displays on one CPU, password protection for integralSETUP menu and modified variables.• Activation of TD 200 editing mode by PLC:Variables embedded in messages can be edited directly withouthaving to press the Enter key or to place the cursor at thevariable.• 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.ProgrammingThe configuration data of the TD 200 are saved in the CPU of theS7-200. The message text strings and configuration parametersare created with the STEP 7 Micro/WIN configuration softwareof V4 and higher. Additional parameterization software is not required.Special data areas are reserved in the CPU of the S7-200 fordata exchange with the TD 200. The TD 200 directly accessesthe respectively required functions of the CPU via these dataareas. A separate TD 200 wizard in STEP 7 Micro/WIN V4 andhigher supports user-friendly parameter assignment.2/16Siemens ST 80 · 2006
