Jeff,
Verify that PRIBLK is set correctly in each block. It should be TRUE (1) for
all but the most Primary (upstream) block. Because AIN is not a Primary block
this means the SWCH bloc should have PRIBLK = 0. What do the other downstream
blocks (BIAS, AOUT) do when SWCH is tracking? Is the SWCH block TOGGLE set to
look at the AIN Input?

Subject: [foxboro] BCALCI/BCALCO question
We're building a control loop that looks like this:
AIN -> SWITCH BLOCK -> BIAS BLOCK -> AOUT
The connections are made automatically in the IACC. When the BCALCI, BCALCO,
BCALC1, BCALC2 connections are made, there is no output out of the switch block
and it indicates it is tracking. When the BCALC connections are removed,
everything works correctly and the switch block no longer indicates
it is tracking. Any thoughts as to why it doesn't work with the BCALC
connections?
Thanks,
Jeff
