CONTROL OUTPUT CO2 C195

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 S

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 input is less than one, the module output will track the reset

feedback input (B)by back calculating 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 con-

trol track command should be AUT.
