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
For the Output Image
1 byte PFC-Outputs
2 byte PFC- Outputs
up to
64 byte PFC- Outputs
1 byte PFC- Inputs
2 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
Visib. String
Octet String
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.
