The module exceeds the maximun external user prmdata count
Hello community, i am using Control Builder F 2013, and i need integrating a redundant ET200M perifery (12 modules). When i add the module I/O 11 it appear the next message "The module exceeds the maximun external user prmdata count". Any idea?

Profibus can handle max 244 bytes per telegram. If total length of all user parameter exceeds 244 bytes you get the error even if you have less than 12 modules.Each module has different length of user parameter data.

The answer from elemravi means, you need to create a second slave on that Profibus
