ABSTRACT:
This invention relates to a modulating controller for controlling two operation terminals, and more particularly to a device to suppress disturbance to a process when a control signal is switched or when a bias is set. This invention, in a modulating controller to control a process amount by the total of two operation terminals disposed in parallel, when either of two H/A station devices outputs a manual operation value, provides a device which outputs a value obtained by reducing the manual operation value from the control amount of the process amount to be controlled by the total of two operation terminals as the control operation signal to the other H/A station device and prepares a value almost same with the operation terminal control signal outputted by one H/A station device as the control operation signal for one H/A station device. And, this invention automatically controls the process amount by either of the two operation terminals disposed in parallel, and in the modulating controller making one side as the backup, one operation terminal control signal is always tracked to the control operation device when both operation terminals are manually operated. When switching the other operation terminal to the automatic operation, timing to switch the other operation terminal to the automatic operation and timing to release tracking are delayed. During which a device to switch the tracking signal to the output of the other operation terminal is disposed.
