Personally I'm a little nervous about this thread. You say that you are "a younger, inexperienced electrical engineer" and "am aware of what a relay coordination study is" - which suggests to me that you haven't actually done one or even truly appreciate what's involved or at stake.
If you do...
I have developed a number of applications using the GE-Fanuc series 90-70 PLC's. These have been working well for some time. But a possible client has asked if I can provide one application on the latest series PAC RX7i controller.
Has anybody experience of converting applications to the new...

At last ... this question, or variants of it, has been posted many times. Your first paragraph is the clearest and most logical answer I recall seeing ... star from me !
You need to appreciate the characteristics of a slow speed diesel engine to understand the difficulties on this subject, which is why I posted in the Marine Engineering forum. The techniques I suggested are not actually "if all else fails" rather they are the very techniques that the major slow...
I work for a stationary power plant that uses slow speed deisel (Sulzer RNF and RTA series) engines. At present in my location there is no specific environmental legislation in place in respect of emissions from the power plant, but this is currently under review.

I think you were right first time. I believe IRR stands for Internal Rate of Return. This is method of financial analysis by which accountants justify withholding money from engineers, who simply want to spend it on fun and interesting projects.

It seems to me that the scheme proposed is a method of providing communications to a remote I/O station, with redundant communications paths (ie. fibre and microwave). At first sight, I would suggest the scheme design will be expensive.
