Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller Installation - Manual (Page 75)

4.1.4 CONTROL OPTIONS
4.1.4.1 REMOTE SETPOINT
1. Configure the RSP input signal parameters:
•
Set C257 to the span (in Engineering Units) of the RSP range.
•
Set C277 to the minimum (in Engineering Units) of the RSP range.
•
The 53MC5000 is set to accept a 1-5 V RSP signal. If 0-5 V is required, set L417=1.
•
The 53MC5000 is set to accept a linear PV signal. If square root extraction is
required, set L441=1.
2. Enable the Remote Setpoint capability by setting L115=1.
3. The 53MC5000 will permit remote setpoint operation if DI1 is closed.
4.1.4.2 FEEDFORWARD INPUT
Additive feedforward provides the ability to add a remotely generated analog value to the control
output of the PID controller:
1. Configure the FF input signal parameters:
•
Set C258 to the span (in Engineering Units) of the FF range.
•
Set C278 to the minimum (in Engineering Units) of the FF range.
•
The 53MC5000 is set to accept a 1-5 V RSP signal. If 0-5 V is required, set
L418=1.
•
The 53MC5000 is set to accept a linear PV signal. If square root extraction is
required, set L442=1.
4.1.4.3 OUTPUT TRACKING
The 53MC5000 is capable of forcing the control output to track an analog value based on the
status of a discrete input. This value can come from two sources; either an internal database loca-
tion or a remotely generated analog signal:
To track an internal database location:
1. Softwire the FCS Auto/Manual module to the internal value to be tracked by setting B160=129.
2. Set C129 to the desired value.
3. Enable Output Tracking by setting L119=1.
4. The 53MC5000 will track C129 only if DI0 is open (0 state).
To track a remotely generated analog signal (AI3):
1. Configure the RSP input signal parameters:
•
Set C259 to the span (in Engineering Units) of the OTV range.
•
Set C279 to the minimum (in Engineering Units) of the OTV range.
