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

(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.
