The gateway signal is held even though the protection signal has reached 0
Hi Support !
I have a problem, please help me!
My system has 3 computers. 2 computers (Host A and Host B use zenon ver 6.5) for HMI. The 3rd computer (gateway function) is used as a gateway to send signals to the dispatching center. The 3rd machine receives data from Server A and Server B. When I pump the fault current to Nari relay PCS9611, the protection signals that are sent to the dispatching center (using IEC-101) are kept (values) variable = 1 at the gateway) while at Host A and Host B the value has already gone to 0.
