Input channel configuration Via configuration software screen or the user program (by writing

a unique bit pattern into the module’s configuration file). Refer to

your controller’s user manual to determine if user program

configuration is supported.

Module OK status indicator On: module has power, has passed internal diagnostics, and is

communicating over the bus.

Off: Any of the above is not true.

Channel diagnostics Over- or under-range by bit reporting, process alarms
