We have two GE Frame V gas turbines installed on our site. Each of the gas turbine is communicating with EX2000 and MarkV HMI (computer based and with cimplicity). The arcnet cables are terminated on CTBA card of the C core. Can we swap these cables on CTBA card? Is it possible while maintaining same functionality?
The reason for doing this is that we are experiencing communication problem between EX2000 and MarkV panel. EX2000 is showing the diagnostic alarm 418 on local display. As the communication link is failed between MarkV and EX2000 we can not reset it from HMI. HMI is only showing two process alarms regarding EX2000 i.e. P389 and P426. P389 tells that the communication link is failed and P426 is showing that there is some diagnostic alarm on EX2000.
I have read the other posts regarding the same problem and their solutions. Unfortunately I don't have authorization to implement any of these on EX2000 (Even I can't reset alarm on EX2000). I was instructed to change the CTBA card without any reason. Instead of changing the card I want to swap the Arcnet cables on CTBA card so that I don't have to change this card if after swapping there is no problem in communication between MarkV and HMI and troubleshooting can be done on EX2000 and the stagelink segment between EX2000 and MarkV.
