We try to add X20DC2396 module on X20BC0063 when we configure the module on Seimens side we find there are 2 modules what is the difference?
Hello,
basically different “operating modes”
Please have a look at the manual
PROFIBUS Bus Controller User’s manual | B&R Industrial Automation
The “C02” offers acyclic transfer of additional registers
Thanks, so does it mean that the module hardware itself is the same, but I can choose different modes in the Siemens software, that is, I can choose either C01 or C02?
Correct. The hardware is the same but different or more data is transfered. In your case acyclic data
