About Command Plus Error Control Mode
The Command Plus Error control mode is typically used to program external controllers. For example, this
control mode may be used for pressurizing aircraft chambers.
When providing programming to external controllers, this control mode corrects the error between the command
and feedback by adding the error into the command (while the external controller maintains closed-loop
control).
