1 byte PFC-Outputs
2 byte PFC- Outputs
up to
64 byte PFC- Outputs
1 byte PFC- Inputs

up to
64 byte PFC- Inputs
PFC configuration modules are used in the GSD file with data type
information from SW 03.
For the Input Image For the Output Image
1 byte PFC-Outputs (data type)
2 byte PFC-Outputs (data type)
etc.
1 byte PFC- Inputs (data type)
2 byte PFC- Inputs (data type)
etc.
Data types: Boolean
Integer8, Integer16, Integer32
Unsigned8, Unsigned16, Unsigned32

The previously used modules are still supported.
By optionally combining the existing modules it is possible to project the
required length on the field bus variables for PROFIBUS DP.
