The 3 single loops are independent and are represented by a diagram equivalent to that of the process loop, with the exception of:
-
The Feed forward branch does not exist.
-
A Split Range or Heat/Cool loop controller cannot be configured.
-
The Process Value and Setpoint branches are simplified.
Single Loop With a PID Loop Controller
The following diagram illustrates a single loop with a PID loop controller.
Only one autotuning operation can be launched at a time on the 3 loops from the process control channel. If a second autotuning operation is requested, it is refused.
