PIO Bus is your fieldbus. If you are having PIO Bus errors and you
have replaced the CP module, check your cabling, TCA, terminators,
terminating resistors, etc... For your CP30s and 40s, do you have
local or remote I/O? If you are using FBIs (which provide full
fieldbus termination) do you also have terminators plugged in to the
cellbus?
Your counters are re-setable. Easiest for the overruns is from the
Station block - access from the SELECT screen.
Your total overruns are less important than the change. How many
control and object manager overruns are you getting in a day? Week?
PIOEGB is FBM good to bad transitions - may indicate noise on the
fieldbus or a faulty FBM or slot.
PP_NFD is bad peer to peer links - C:B.P references from one block
that do not exist. You can use the dbvu tool to examine your
checkpoint file and get details on these. These may be important to
fix unless they are in unused logic.
PIOE1R is no longer used - should not be incrementing.
PIOEFT - fault tolerant output mismatches - your CPs are fault
tolerant? This counter increments when (as I understand it) there is
a difference between what the shadow CP would have written to the FBM
and what the primary CP did write to the FBM.
