Features:
- PROFIBUS FDL role: Siemens uses CP 5431 in an S5 station for FDL communication with free Layer 2 access.
- SDA data service: the documented communication example uses Send Data with Acknowledge between the S7 and S5 stations.
- S5-system context: the example places the processor in an S5-135U/155U station with CPU 928.
6GK1543-1AA01 is the CP 5431 used by the passive S5 station in Siemens’ documented S5-to-S7 communication example.
The example uses a PROFIBUS network and an FDL/SDA data exchange, so the installed communication arrangement is the relevant engineering context.
Siemens notes that its sample project uses a specific hardware configuration; a different CPU or communication processor requires the sample program to be changed accordingly.
Apter Power supports documentation review, quotation and procurement for the Siemens 6GK1543-1AA01 CP 5431 Communications Processor.
