2.7 Adapting the Process Data Mapping
The mapping of process data can be adapted application-specifically via the IO-Link-master's
parameterization.
Depending on the used fieldbus, it can be necessary to swap process data word-wise, double word-
wise or completely in order to align them to the data structure in the PLC.
The process data mapping is determined channel by channel through the parameters "process
input data mapping" and "process output data mapping" (see
Parameters, s. page 14 ).
Example mapping for field buses with Little Endian-format:
