Description
SP2 Operator value, scaled in PV units. SP2 set to
this value when Operator control.
If value of SP2Prog or SP2Oper < SP2LLimit or >
SP2HLimit, set bit in Status and limit value used
for SP.
SP1 high limit value, scaled in PV units.
• If SP1LLimit < PV1EUMin, or SP1HLimit >
PV1EUMax, set bit in Status.
• If SP1HLimit < SP1LLimit, set bit in Status and
limit SP by using the value of S1PLLimit.
SP2 high limit value, scaled in PV units.
• If SP2LLimit < PV2EUMin, or SP2HLimit >
PV2EUMax, set bit in Status.
• If SP2HLimit < SP2LLimit, set bit in Status and
limit SP by using the value of SPLLimit.
SP1 low limit value, scaled in PV units.
• If SP1LLimit < PV1EUMin, or SP1HLimit >
PV1EUMax, set bit in Status.
• If SP1HLimit < SP1LLimit, set bit in Status and
limit SP by using the value of SPLLimit.
SP2 low limit value, scaled in PV units.
• If SP2LLimit < PV2EUMin, or SP2HLimit >
PV2EUMax, set bit in Status.
• If SP2HLimit < SP2LLimit, set bit in Status and
limit SP by using the value of SPLLimit.
Control variable 1 bad health indicator. If CV1EU
controls an analog output, then CV1Fault will
normally come from the analog output's fault
status.
If CV1Fault is TRUE, it indicates an error on the
output module, set bit in Status.FALSE = Good
Health
Control variable 2 bad health indicator. If CV2EU
controls an analog output, then CV2Fault will
normally come from the analog output's fault
status.
If CV2Fault is TRUE, it indicates an error on the
output module, set bit in Status.FALSE = Good
Health
Control variable 3 bad health indicator. If CV3EU
controls an analog output, then CV3Fault will
normally come from the analog output's fault
status.
If CV3Fault is TRUE, it indicates an error on the
output module, set bit in Status.FALSE = Good
Health
