Setpoint Related Datapoints (Primary, Secondary)
C114,
C150 5-9 CON0,
CON1 Control Zone - A gap on both sides of setpoint. When PV is
within this gap, the proportional and integral output changes
are suppressed. Derivative output is unaffected. 0
C125,
C161 5-9 CON0,
CON1 Setpoint High Limit - It is the maximum setpoint value
allowed. 100
C126,
C162 5-9 CON0,
CON1 Setpoint Low Limit - It is the minimum setpoint value allowed. 0
C117,
C153 5-9 CON0,
CON1 Setpoint Slew Rate - It is a rate limit applied to the setpoint.
When configured to a non-zero value, the setpoint used in
the PID algorithm is only allowed to change by this amount
each scan time. The final value of the setpoint always
appears on the units display. A zero disables setpoint
slewing. 0
Miscellaneous Datapoints (Primary, Secondary)
A000,
A002 5-9 CON0,
CON1 Tagname - Assignable 10 character name. CON-
0, 1
A001,
A003 5-9 CON0,
CON1 Engineering Units - Assignable 10 character designator.
(Engineering Units appear on the Single Loop CON0 and
Single Loop CON1 displays only.) PER-
CENT
L109,
L133 5-9 CON0,
CON1 Reverse Valve - Bottom of display loop output valve action
indicators: 1 = [O] [C] display order, 0 = [C] [O] display
order. (Reverse Valve indicators appear on the Single Loop
CON0 and Single Loop CON1 displays only.) 0
