The logic execution is thought of as “power flow”, which proceeds down along the left “rail” of the ladder, and from left to right along each rung in sequence. Figure 55 The flow of logical power through each rung is controlled by a set of simple program functions that work like mechanical relays and output coils.

Page 276: Error Term
User Manual Chapter 14 GFK-1503F Jan 2020 The ISA (PID_ISA) algorithm has different coefficients for the terms: PID Output = Kc * (Error + Error * dt/Ti + Td * Derivative) + CV Bias where Kc is the controller gain, Ti is the Integral time and Td is the Derivative time. The advantage of PID_ISA is that adjusting Kc changes the contribution for the integral and derivative terms as well as the proportional term, which can simplify loop tuning.
