We're talking about it here, but we don't see any way to do it without building a companion CALC block for every PIDA block, which isn't going to happen. Tim, I have always done this with one calc block per pida, tying SPHLIM and SPLLIM to the appropriate real outputs. I start with the critical controllers and do others as time permits. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
