Wire Size and Terminal Screw Torque

Each terminal accepts as many as two wires with these restrictions:

I/O Memory Mapping

Output Data File

For each module, slot x, word 0 in the output data file contains the control
program’s directed state of the discrete output points.

w = write

Output Module’s Input Data File

For each module, slot x, input data file word 0 contains the state of the module’s
output data (output data echo) file word 0. During normal operation, these input
bits represent the logic state that the outputs are directed to by the control program.
They are also dependent upon the:

• Program Mode configuration (if supported by the controller)
• The Fault Mode configuration (if supported by the controller)
