InitPrimary is set
(1)
WindupHOut is set
WindupLOut is set
CVInitializing is set or not Cascade/Ratio mode
(2)
CVInitializing is cleared and Cascade/Ration mode
(3)
SHPAlarm is set or appropriate Cv alarm
(5)
SHPAlarm is cleared and no CV alarm
(6)
SPAlarm is set or appropriate CV alarm
(7)

(8)
1. During first scan, the instruction sets InitPrimary
2. When CVInitializing is set or when not in Cascade/Ratio mode, the
instruction sets InitPrimary.
3. When CVInitializing is cleared and in Cascasde/Ratio mode, the
instruction clears InitPrimary.
4. During instruction first scan, the instruction clears the windup outputs.
The instruction also clears the windup outputs and disables the CV windup
algorithm when CVInitializing is set or if either CVFaulted or
CVEUSpanlnv is set.
5. The instruction sets WindupHOut when SPHalarm is set, or when
ControlAction is cleared and CVHAlarm is set, or when ControlAction is
set and CVLAarm is set.
The SP and CV limits operate independently. A SP high limit does not
prevent CV from increasing in value. Likewise, a CV high or low limit does
not prevent SP from increasing in value.
6. The instruction clears WindupHOut when SPHalarm is cleared, and not
(ControlAction is cleared and CVHAlarm is set), and not (ControlAction
is set and CVLAlarm is set).
7. The instruction sets WinindupLOut when SPLAlarm is set, or when
ControlAction is cleared and CVLAlarm is set or when ControlAction is
set and CVHAlarm is set.
The SP and CV limits operate independently. A SP low limit does not
prevent CV from increasing in value likewise a CV low or high limit does
not prevent SP from increasing in value.
