Abstract

PURPOSE: To reduce the effect caused by the trouble of the master station, by setting the master station when a connection is given to each digital control device by the data transmission line and the information is available to be received by each control device and thus having no specified master station.
CONSTITUTION: The digital controllers 3-1, 3-2W3-n are provided to each of the control loops, and no specified master station exists among these controllers. These controllers obtain the process variable from the process sensor for each of their process control, and then deliver the quantity of operation to the operation terminal to control each control loop. When one of these controllers wants some information from other controllers, the controller has a role of the master station to obtain the desired information through the data transmission line 32.
