XBTGT HMI cannot open connection with Quantum PLC

Published date: 24 September 2019

Issue:
NOE 771 card has a fault light activated

Product Line:
Quantum PLC
NOE 771
Magelis XBTGT7340

Cause:
A new IED was added to the network and had its IP configured to be the same as the NOE 771.
This resulted in the NOE 771 card crashing due to duplicated IP Address.
The crashing/faulting of NOE Card meant the HMI was no longer able to communicate with PLC system

Resolution:
Make sure the IP address of the NOE 771 card is different than any other device on the network
