We have Mark V TMR system in our site and we want to make it become simplex system. Any experiences about changing TMR to Simplex?
Because there would be limited spare parts in <S>, <T> and <QD1>, AND if they can't get a READY TO START because of a problem with one of the TMR components they could start as a SIMPLEX.
I'm not going to go into the details of every step, but here's the outline of what has to happen. You need a SIMPLEX FORMAT file for BOTH <R> and <C>. You need to loop <R>'s IONET from <X> to <Y> <Z> to the TCDA in <QD1>. There are a couple of oddities with <Q> I/O (in IO.ASG) that would need sorting out. And, I believe there is some change that has to be made to MSTR_SEQ.CFG, and possibly CONFIG.DAT. MK5MAKE, EEPROM DOWN USER (after EEPROM DOWN FORMAT and a hard re-boot of both <R> and<C> (and another hard re-boot of both processors, starting with <R>). I think the DENET from <R> to <S> would also have to be disconnected and there might be some jumpers in <R> that would have to be reset, and maybe some jumpers in <P>, too, and that should be about it.
OH--forgot there would have to be some servo wiring changes, and LVDT wiring changes, too. And probably some ribbon cables to <S> and <T>
would have to be made. And I believe there would have to be some ribbon cable changes from the TBQA to the TCQA (for T/CS).
Finally, to have true protection for a GT, there would have to be some I/O moved from <R> to <C>, and some logic changes.
Not impossible. Not easy. Not recommended, especially if the unit is a GT with DLN combustors.
Never heard of it being tried, except in a lab setting without a real turbine and I/O.
Best of luck.
It's a Panel for training in Lab. Like CSA said, we need to make additional spare so we want to remove <S> <T> into stock.
We only use IO for servo testing. And other IO is just for testing as needed.
So what should we do in cable that has daisy chain to <R> <S> <T> ,such as VARC ?
And also JL cable that connect from <X><Y><Z> ?
Are there any GE document that explain about Simplex system?

I believe VARC is the DENET.

Not familiar with that one, and I don't have access to my Mark V manuals at this writing.

Not that I'm aware of.
