Ok, well this might be a bit off the subject, but here goes. Feel free to move it.
I have this project to bid where I am migrating a Joe White Malting Machine…which was built in your backyard somewhere around '96-'98 (actually Sumwerlakes Parade Ballajura, WA on last rev).
Anyway I am migrating the B100/B200’s to E1’s and E2 and then I was going to S1 it and use PPPro. The problem is that although they did an excellent job and the code is really nice and clean and notated and documented, there are 53 charts, and approx. 500 uses of the stop, start, continue, pause charts commands. That would not be the worst of it except the sequence of the strategy has no single main chart, so figuring out the sequence might be a lot of work.
Here is the quandary, I know that these chart commands may or may not be a problem, it really depends on how often they were used, etc, etc. If it only delays the operation of the machine here and there by 100ms, so what. However, if they used the commands in the right way, it could cause some strange operations if the chart queue gets filled up and then starts doing who knows what.
Do I just migrate the hardware to an S1, fire it up and see what happens at customer site (out of town) or, use SoftPac to brute force it, or go through the whole thing with an Excel spreadsheet and make a map of the sequence and then reassemble all the parts in the correct sequence in maybe a quarter of the charts?
I had another thought, make a main chart that provides the sequence control and use bits or integers in that chart in place of the start/stop/and continue commands?
Does SoftPac have exactly the same chart switch issue as S1, and would the 100 fold speed increase solve the problem or make it worse?
