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
(1) Output ripple is the amount a fixed output varies with time, assuming a constant load and
temperature.
(2) Repeatability is the ability of the output module to reproduce output readings when the same
controller value is applied to it consecutively, under the same conditions and in the same direction.
(3) Rated working voltage is the maximum continuous voltage that can be applied at the output terminal,
including the output signal and the value that floats above ground potential (for example, 10V dc
output signal and 20V dc potential above ground).
