SP low limit value, scaled in PV units.
If SPLLimit < PVEUMin, or SPHLimit <
SPLLimit, 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.
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.
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.
CV1 initialization request. While TRUE,
set CV1EU to the value of CVInitValue.
This signal will normally be controlled
by the In Hold status on the analog
output module controlled by CV1EU or
from the InitPrimary output of a
secondary loop.
CV2 initialization request. While TRUE,
set CV2EU to the value of CVInitValue.
This signal will normally be controlled
by the In Hold status on the analog
output module controlled by CV2EU or
from the InitPrimary output of a
secondary loop.
CV3 initialization request. While TRUE,
set CV3EU to the value of CVInitValue.
This signal will normally be controlled
by the In Hold status on the analog
output module controlled by CV32EU
or from the InitPrimary output of a
secondary loop.
