Chapter 1 Overview
Each time a new output value is sent to the module, it is tested for an
over-range or under-range condition. In addition, the module
supports user-configured high and low output clamps for each output
channel. If any of these conditions are detected, unique bits are set in
the output-channel status word.
The channel status words are described in the
The controller uses two’s complement binary data when
communicating with the module. This typically occurs at the end of
the program scan or when commanded by the control program. If the
controller and the module determine that the bus data transfer was
made without error, the input data is used in your control program
and the output data is used by the module.
No field calibration is required.
