Integration options

The integration options parameter (INTEG_OPTS) allows you to specify integration and reset behavior. You can set integration options in any mode. The following integration options are supported in the Integrator function block:
  • Carry — Determines what to do with the integration value after a reset condition is reached. When the Carry option is not enabled (False), the integrated value starts over (at zero or SP) when it is reset. When the Carry option is enabled (True), the excess values are carried over past the trip point into the next integration cycle as the initial value of the integrator.

  • Flow Reverse — Determines the net flow direction. When Flow Reverse is selected (True), negative increments are included in the integration.

  • Flow Forward — Determines the net flow direction. When Flow Forward is selected (True), positive increments are included in the integration.

When both Flow Forward and Flow Reverse are selected, positive and negative increments are included in the integration.
