Command Series Migration to MOD 30ML
Pre-configured Single 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
