Hi, we are trying to use Open PDC to connect some old RES521 ABB pmus using 1344 protocol. When try to connect PMUs we see on the console this message: "index was outside the bounds of the array" and PMU is disconnected. On the same workstation with same configuration parameters, we connect with 1344 protocol the same PMU with TVA without any problem. Seems a problem related to the 1344 library of OPENPDC ....

Are you connecting to the same port? The ABB PMU's can be configured to report different protocols on different ports.

Have you tried using the PMU Connection Tester?

This tool is normally already installed with openPDC.

Also - what version of the openPDC are using? One openPDC user we assist still connects to older ABB-521 units with their openPDC with issue.

Thank you, we solved. The problem, signalled by my colleague Pietro, was related to digital inputs od ABB PMU. Disabling on the PMU the protocol 1344 works. Best regards. Giorgio
