2.9 Process data words
The module uses 8, 16, or 24 words in the VersaPoint system. How these words are
mapped is described in "Process image" on page A-13.
The input data only indicates the actual status of the outputs if no bus errors or device
errors are present. Even during the parameterized switch-off delay in stop category 1, the
status of the outputs on the module does not correspond to the status of the outputs on the
controller.
The parameterization of the outputs determines whether the input data is mapped in
single-channel or two-channel mode. The value for "parameterized output" for the outputs
is also set for the input data.
