Terry,
Thanks for that heads up, I'll also check the existing CP40 loading...

Joe,
Another item that requires some care is the fact that the CP40B incorporates
memory error detection and correction. This takes up some cpu power.
There were instances where a CP40A (original CP40) would run OK but the
CP40B experienced overruns. The excel spreadsheet for each type of CP
could be used to try and determine the loading difference you can expect to
see. The absolute number on the spreadsheets (CP40B and CP40A) may not be
the same as real performance but the ratio excel CP40B / CP40A, should
give you expected performance compared to your current CP40A station display
load.
If my memory is correct, high field bus load made the situation worse.
