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.
