Product DescriptionApplications ofTD171With text display TD17, you can visualize the operating states, malfunctionsand current process values of a connected PLC.The Text Display features a number of standard functions. The displays andoperation of the device can be optimized by the configurer to meet the requirements of the process.The TD17 is suitable for installation in cabinets and consoles.1.1Configuration and Process Control PhasesCreating dataareasBefore the TD17 can be commissioned, it has to be prepared for its job ofvisualizing data from the PLC; in other words, it has to be configured. Thismeans that you have to create data areas in the PLC memory in your configuration which can be used by the TD to communicate with the PLC.Configuring withProToolThe configuration for your TD17 is created on a computer (PC or PU) usingthe ProTool configuration software under MicrosoftR WindowsT. Once theconfiguration is ready, it is downloaded to the TD. For this you have to connect your computer to the TD. After the configuration has been downloaded,you have to connect the TD to the PLC.The TD now communicates with the PLC and reacts to program flows on thePLC on the basis of the configured requirements.TD17 Equipment ManualEdition 06/971-1
Product DescriptionFigure 1-1 outlines the configuration and process control phases. Figure 1-1Static and variabletext components Configuration and Process Control PhaseText which is required to be displayed on the TD17 has first to be created onthe PC or PU with ProTool and then downloaded to the Text Display. If, forexample, the text you wish to display has to consist of static and variablecomponents, the variables have to be configured and the static text for explaining the variables has to be entered – for example:Temperature Variable1 C of Furnace1where Temperature C of Furnace1 is the static text andVariable1 is the variable that is read from the memory area of the PLC.Furtherinformation1-2You will find information on configuring the TD in the ProTool/Lite User’sGuide. The Communication User’s Guide provides information on connectingthe TD to the PLC.TD17 Equipment ManualEdition 06/97
Product Description1.2Functions of a Text DisplayDisplay functionsThe basic function of a Text Display consists in displaying process states.The following display functions can be configured for the TD17: event messages information text languages.Event messagesEvent messages are information and operating notes on current machine orprocess states. Event messages may contain process values. Process valuesare displayed either numerically – for example,Motor running at 3000 revs.or symbolically – for example,Motor running normally,where a specific control value is assigned to normally.You classify a message as an event message when you are configuring.Information textInformation text is additional information and hints on operation referring tothe current display. This means that additional information can be displayedwhen an event message is issued.LanguagesMessage text, information text and system messages may be displayed inseveral languages. Up to three of the following languages can be loaded simultaneously on the TD17 and selected in online mode by the operator: German English French Italian Spanish and Russian (Cyrillic characters).TD17 Equipment ManualEdition 06/971-3
Product Description1.3Design of the TD17TD17 versionsThe TD17 has a plastic housing with a touch-sensitive front and is thus suitable for ungrounded installation. The coloring of the universal front foil complies with machinery directive EN 60204. Figure 1-2 shows the design of theTD17.

Operatingdata are retained in a non-volatile state in the flash memory on the TD. Theinternal hardware clock has reserve power for several days after the power isturned off.The TD17 can be upgraded with an optional lithium battery to back up themessage buffer and the hardware clock (longer than the reserve power). Thebattery is not supplied with the TD.Interfaces 1 x RS232/TTY for connecting to the PLC or computer 1 x RS422/485 for connecting to the PLC or computer.FuseMaintenance-free electronic fuse.1-4TD17 Equipment ManualEdition 06/97

Standard Functions4Loading aconfigurationAfter the operating voltage has been turned on, a configuration has to beloaded onto the TD so that it can be operated. The TD remains in Downloadmode until a configuration is loaded.Using standardscreensThe TD17’s firmware contains a number of standard screens. You use thesestandard screens to select all the functions necessary for operating the TD.The individual functions are described in this manual by means of the standard screens.4.1Operating LevelsMessage level andstandard screenlevelWhen operating the TD, you have to distinguish between two different operating levels, it being possible to switch from one to the other. Message level:The message level is the highest level on the TD. All waiting event messages and system messages are displayed at message level. Followingstartup, the TD is always at message level. Standard screen level:At standard screen level, functions are selected, processed and executed.When you select standard screen level, the directory of the standardscreens appears from which you can branch to the different standardscreens.If a system message is queuing and the TD is at standard screen level, the TDchanges immediately to message level.TD17 Equipment ManualEdition 06/974-1
Standard FunctionsChangingoperating levelsChanges of operating level are performed either manually or automaticallyby the TD (refer to Figure 4-1). Operator-initiated change:Press the following key:ENTERto change from message level to standard screen levelESCto change from standard screen level to message level. Forced change to message level:You exit from standard screen level automatically as soon as a systemmessage is waiting to be displayed. The TD then goes to message level.To hide a system message, pressESC.Once the system message has been hidden, the TD17 reverts to the pointfrom which it previously went to message level.
