Hello Everyone,
I have a SCADA project with WinCC OA 3.12 and SIEMENS Siprotec 4 Protection relays. I can successfully read values from protection relays. But i can't create output. I have to control circuit breakers from SCADA. I can get circuit breaker positions from IEDNAME/CTRL/Q0XCBR1 but i cant control it.
I try to set value of IEDNAME/CTRL/Q0CSWI1/CO/Pos/ctVal. But there is no action. There is no interlock in the relay. I also tried to use Reset LED (LLN0) function to test how to create output. But its same.
Is there any circuit breaker object library for IEC61850 ?
I would be very pleased if you can help me to solve this problem.
Best Regards
