IEC61850 Driver - Report control blocks - Communication Problem

IEC61850 Driver - Report control blocks - Communication Problem

I'm working on Zenon Operator 7.50. I have read IEC850 Zenon Driver Manual. I need to connect to a device via IEC61850 protocol. I detected 2 different working case: CASE 1: if my device doesn't include REPORT CONTROL BLOCKS -> ZENON reads variables from device OK (Variable ConnectionState = 65538 -> TCP Connection and MMS are ok) CASE 2: if my device include Variable ConnectionState = 2 only TCP Connection is OK) My problem is: new configuration of my device include REPORT CONTROL BLOCK automatically, therefore zenon is not able to read desired variables from the device. What can I set in IEC61850 Configuration Driver to enable the communication? I tried to set 0 Max auto used URCBs field but communication still not working. Any idea? Thank you, Andrea
