Command Series Migration to MOD 30ML
Pre-configured Dual Loop PID Control
EXPLANATION
Configuration with this compound requires understanding of the compound and how the
PID block is configured in the MOD 30ML/Modcell controllers. Following is the
reference that includes listing of most commonly used / changed attribute and inputs and
outputs. Necessary block configuration tabs are also explained to make it easier.
INPUTS – OUTPUTS
The I/O table is identical to both the loop compounds.
Signal Block Type Description
S1 PID Input – S1
Floating Point Result (R) of the VCI block VCI-1 is
already connected to PID.S1 signal of
the compound for the first loop.
Result (R) of the VCI block VCI-2 is
already connected to PID.S1 signal of
the compound for the second loop.
Process Input signals.
S1Q QUALLOGIC Output – S1Q
Boolean (Discrete) Connect to the QUALLOGIC.S1Q
signal of the compound. Process Input
Quality
S2 N/A N/A N/A
S3 PID Input – S3
Floating Point Connect to the PID.S3 signal of the
compound. Track Reference.
S4 PID Input – S4
Boolean Connect to the PID.S4 signal of the
compound. Track Switch.
S5 PID Input – Floating
Point Change in the Control tab of the
corresponding PID block. Change the
value for MANUAL RESET – BASE
VALUE.
S6 PID Input – S6
Floating Point Feed-forward input for the PID. Enable
in the Options tab of the PID block.
Change the calculation type to Add.
Connect the feed forward input to the
PID.S6 signal of the compound.
