Configuration Of The Field Bus Variables - WAGO I/O SYSTEM 750 750-833 Manual

3.6.2 Configuration of the Field Bus Variables

With the 750-833, after configuration of the connected periphery, the memory
area is configured due to the variable arrangement of the field bus variables.
There are configuration modules up to SW 02.
For the Input Image
1 byte PFC-Outputs
2 byte PFC- Outputs
64 byte PFC- Outputs
PFC configuration modules are used in the GSD file with data type
information from SW 03.
For the Input Image
1 byte PFC-Outputs (data type)
2 byte PFC-Outputs (data type)
Data types:
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.
Attention
The SFC 14 or SFC 15 is to be used with S7 if the PFC inputs or PFC outputs
are more than 4 bytes. The same also applies for I/O modules with a data
width of more than 4 bytes.
