IMC Function Block Initialize

A Model Initialization occurs:
  • during First Scan of the block
  • when the ModelInit request parameter is set
  • when DeltaT changes
You may need to manually adjust the internal model parameters or the response time constants. You can do so by changing the appropriate parameters and setting the appropriate ModelInit bit. The internal states of the function block will be initialized, and the bit will automatically reset.
For example, if you modify the IMC function block Model Gain for CV - PV, set the ModelInit parameter to TRUE to initialize the CV - PV internal model parameters and for the new model gain to take effect.
