External Input Setup
Input devices can be connected to the system monitor via Input/Output (I/O) Combination Interface Modules. You
must 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 Function
To select External Input Setup, press FUNCTION until you see the message:
Press STEP to continue.
External Input Configuration
If 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 DEVICES
If input devices are installed, the system recognizes the presence and module slot locations of I/O Combination
Interface Modules. It also establishes a module number based on the slot location. For example, if modules are
installed in slots #3 and #6, the module in slot #3 automatically becomes module #1 and the module in slot #6
becomes module #2.
As you specify which input positions on a module are connected to external devices, the system establishes a
number 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 X
for that position.
SPECIFYING INPUT POSITIONS
To indicate whether position 1 is connected, press CHANGE until the correct choice appears (1 if the position is
connected, X if it is not). Press the Right Arrow key to move to position 2 and press CHANGE again until the
correct 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 CONFIG
message for the next module.Up to 8 modules may be installed. Repeat the steps described above for each
