23-123 External Input SetupInput devices can be connected to the system monitor via Input/Output (I/O) Combination Interface Modules. Youmust enter data individually for each input device. The information you enter tells the system the number, location,type, and name of installed input devices.Selecting the External Input Setup FunctionTo select External Input Setup, press FUNCTION until you see the message:Press STEP to continue.External Input ConfigurationIf necessary, press STEP until you see the message:Use this display to tell the system which input positions on a module are connected to external devices.NOTE: If external devices are not installed, this function is not available.HOW THE SYSTEM CONFIGURES INPUT DEVICESIf input devices are installed, the system recognizes the presence and module slot locations of I/O CombinationInterface Modules. It also establishes a module number based on the slot location. For example, if modules areinstalled in slots #3 and #6, the module in slot #3 automatically becomes module #1 and the module in slot #6becomes module #2.As you specify which input positions on a module are connected to external devices, the system establishes anumber for each input position. For example, if an external device is connected to positions 1 and 2 of module 1,input position 1 becomes I1 and input position 2 becomes I2.To indicate that an input position on the module is connected, choose the number corresponding to that position.For example, if the position is 3, choose 3 for the position. To indicate that a position is not connected, choose Xfor that position.SPECIFYING INPUT POSITIONSTo indicate whether position 1 is connected, press CHANGE until the correct choice appears (1 if the position isconnected, X if it is not). Press the Right Arrow key to move to position 2 and press CHANGE again until thecorrect choice appears. When you have entered a choice for both positions, press ENTER to confirm your entry:Press STEP. If more than one module is installed, the system automatically advances to the INPUT CONFIGmessage for the next module.Up to 8 modules may be installed.
