CONTROL OUTPUT CO0 C123

Description:

This module computes a control output signal based on the above listed inputs and parameters.

The result is simultaneously available as the module output Sn and as a database parameter CO.

The A, B, and C inputs can be any L,B, C[S], or H type datapoint. When the control track command

lating the integrator term. When (C) input is greater than or equal to 1 the reset feedback is used

by the integrator to calculate the next output and should reflect the value (scaled 0-100%) of the

value of the final control element. For standard PID controller reset feedback, (B) should be OUT

and control track command should be AUT.
