Greetings to the forum. My name is Michael and I'm a newbie to GE controls particularly the Mark V.
I've done some work over the years with various instrumentation, controls, and PLC type systems so I'm not totally green. For about a year now I have been working in the power generation industry, notably a combined cycle power plant utilizing one GE 6FA type gas turbine. Having never seen a Mark V system, I have been spending quite some time trying to understand how it all operates under the hood. I've been reading the manuals: User's, Maintenance and Application as well as trying to decipher the unit specific files on the HMI. I've also been perusing through quite a number of posts on this site of which there is a wealth of knowledge and quite obviously intelligent folks. I have many questions and I've searched the site and did not find exactly the answer I was looking for and please forgive me in advance if the answer is here and I just simply overlooked it.
At the moment I'm trying to wrap my mind around signal addressing, naming and basically the overall marriage of signals to physical I/O. I've been digging around in the TC2KREPT, IO.ASG, CSP and other files trying to piece together exactly which signal goes to what termination board and from there to what board in the core. I've come across termination boards with wiring landed to certain I/O of which I can't locate anything defined in any of the aforementioned files. Am I right in the belief that if there is nothing noted in the IO.ASG file that there is nothing configured in the Mark V for a particular input or output? Also are there non configurable I/O in some of the Core units such as with a P Core and items landed on the PTBA termination board? I was searching for the E-Stop and ETR signals in the various files that land at the P core and could not find them and thought that perhaps they had a fixed function and operated independently from any configuration.
I'll leave it at that for now. Any help with my questions and any advice as to how to tackle learning the Mark V is greatly appreciated. Thank you all for the great threads here.
