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 LED 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

Maximum Overload at Input

(1)

Repeatability is the ability of the input module to register the same reading in successive measurements for the same input

signal.

(2)

Damage may occur to the input circuit if this value is exceeded.
