12.4.4 Preparing the control system for consistent data transmission
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 + service
pack 5 (V5.4+SP5) or higher is used.
12.5 Variable configuration of the communication data width
The communication of the MA 248i with the fieldbus system can be configured with a vari-
able data width; the upper limit is restricted by the fieldbus. The following sizes are available
for the data frame for PROFINET-IO:
4 … 1024 bytes
