Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller Installation - Manual (Page 61)

SETPOINT TRACKING ENABLE:
When the Setpoint Tracking Enable bit STE (L118) is configured to a 1 the controller’s setpoint can
be forced to match Setpoint Track Value STV (C128) when Setpoint Track Switch SWSPT (L116)
is a 0. Based on the sources of the later two data points; PV tracking, SP fallback, SP override and
other schemes can be implemented in the local setpoint generator.
SETPOINT LIMITS:
Parameters SH (C125) and SL (C126) are configured to indicate the maximum and minimum con-
troller setpoint value allowed. These parameters are applied to the final output of the setpoint
generator and thus effect the remote and track setpoint results.
OUTPUT HIGH AND LOW LIMIT:
Parameters OH (C109) and OL (C110) are configured to indicate the maximum and minimum con-
troller output value in percent. These values may or may not be applied to the output in manual op-
eration, depending on the setting of Hard Manual Limiting bit HML (L122).
OUTPUT SLEW RATE:
The value configured into parameter T3 (C118) is the maximum output change in percent allowed
for the PID algorithm. A zero disables output slewing. This value has no effect on the manual op-
eration of output.
OUTPUT TRACK ENABLE:
When Output Tracking Enable bit OTE (L119) is configured to a 1 the controller’s output can be
forced to match Output Track Value OTV (C129) when Output Track Switch SWOVT (L117) is a 0.
Based on the sources of the later two data points; Output fallback or override as well as other
schemes can be implemented in the auto/manual switch generator.
AUTO ENABLE:
When the Auto Enable bit AE (L114) is a 1 the control output CO (C123) becomes the auto/manual
generator result OUT (C102) based on the A/M pushbutton or if the auto switch SWA (L112) is a 1.
HARD MANUAL LIMITING:
This parameter HML (L122) when set to a 1 applies the output limits to the final output of the
auto/manual generator, effecting both the manual pushbutton and the controller’s result.
REVERSE VALVE:
This parameter provides information for the various control displays to indicate which direction the
control output must go to close the final control element. A "1" indicates that 20mA closes the valve.
ALARM LIMITS:
These parameters PL1 (C103) and PL2 (C104) are the points in engineering units at which the
alarms are triggered.
ALARM DEAD BAND:
Parameter ADB (C105) sets the activation/deactivation gap for the alarm. This value in engineering
units defines an area of hysteresis at the alarm point.
