Setpoint Rate Up Setpoint Rate Up
Setpoint Rate Up
R/W Ramp rate at which upward setpoint changes are acted on in
"Auto" mode, in PV units per second. If the ramp rate is set to
zero or the block is in a mode other than "Auto", then the
setpoint will be used immediately.

R/W Options which the user may select in the block processing of
status.
No option selected
Setting:
•
IFS if Bad IN: Set Initiate Fault State status in OUT if the
status of IN is "Bad".
•
IFS if Bad CAS_IN: Set Initiate Fault State status in OUT if the
status of CAS_IN is "Bad".
•
Use Uncertain as Good: If the status of IN is "Uncertain",
treat it as "Good" otherwise treat it as "Bad".
•
Target to Man if Bad IN: Set the target mode to "Man" if the
status of the IN parameter is "Bad". This latches a PID block
into the "Man" state of the input ever goes "Bad".
•
Target to next permitted mode if BAD CAS_IN
