We also have CP60's (3.30/OP)and FCM10e (1.16/OK)(and a couple of ef's) and we experienced the same errors as you did. Our i/o's are +/- 130m from the CP's and we still used coax. Changing coax to Fibre took care of most of the errors. If you are already using fibre (I suppose you are because you have FCM10EF's) and you always have the errors on the same bus you might want to change the fibre patchcable, or if you have FT FCM's you could try swapping the FCM from the problem bus with an FCM that does not cause problems. If the errors move to the other FCM, you've found the origin of the errors. I suppose the CP60 was not one of Foxboro's most reliable processors, we've had problems with them from the start, I think they've all been exchanged for newer revisions about 3 times by now. We're planning on upgrading to ZCP270's if and when I ever get a price quote from Foxboro (applied for a quote in febr, still haven't received any quotes yet....)

We are experiencing excessive PIO bus errors from four of the CP's I have implemented the recommendations of the "SA2005064I - QF1007465b" and all FCM's are on software revision 1.16. I have monitored the PIOE1R, PIOEFT, PIOEGB parameters using the "all-pio-read" and "all-pio-reset" scripts and have not recoreded any errors on the problematic CP's. The System Monitor still records messages with PIO bus falures and errors for these CP's.
