Has anyone encountered a problem integrating SIPROTEC 4 & 5 IEDs with ABB RTU560 using IEC61850. Whenever, I connect the SIP4 IED (7UT633) to the network, the RTU560 loses communication to National Control Centre. When it is disconnected from the LAN, the SIP5 IEDS (7SA82, 7SJ82) work perfectly.

The tests show that the IEDs have been successfully integrated to the RTU and IEC61850 communication is functioning properly on the local network. However, the RTU communication to NCC is cut off. Is it a problem of conversion of IEC61850 data to IEC ...101 link to NCC?
