Good morning
at first I apologize for my bad English, and I hope this is the right section to do my questions. I would like to ask you help about a problem with the communication between DCS and MakV.
In particular we have two turbine unit controlled by MKV and one DCS system. Each turbine unit have one PC HMI (HMI TG1 and HMI TG2). The configuration of the PC HMI offer the possibility to control both TG1 and TG2 with only one PC HMI.
During last week we noticed that the communication between the systems falls and DCS doesn't read the data from MKV. I opened the page of DCS's application where, in normal conditions, there are a list of parameter read from MKV. In this case there was a long messages list with a series of "Point Cmd not definite IDHint: number", and one of the last (not the least) was: "Point not definite : Controller T1 Point Name L30VL2" (this is strange because L30VL2 is the feedback from the power distribution).
After a long series of effort I restart the communication in this way:
stop the TCI service on the HMI
stop the RCE_GSM on the DCS Client
then start TCI and RCE_GSM
At the moment remains the problem of the list of not definite points that (I suppose) sometimes cause the stop of the service (from the DCS, because on the HMI the GSM application continue to run).
My questions are:
- do you think I have to continue to looking for a problem on the HMI/MKV side or there should be a problem with DCS?
- How GSM manage the communication to DCS? In other words, in one HMI master and the other slave (or stand-by)?
- I saw that the hard disk of the PC HMI TG2 have one more partition than the other HMI. This partition is named HMI(D. This means that in this section there are files for the HMI functions, or those files are in the partition G: where are GSM.exe files and other .exe files?
- do you think it could be helpful recompile the GSM database in order to be sure all points are correct? If yes, can you send me a procedure to do this operation?
I hope to have given you information clear enough to understand my problem.
Thank you very much in advance
best regards
