ABSTRACT:
A plant controller calculates the updated value of a control parameter for a motor controller for controlling motors for driving process machines in accordance with the change in the operational condition of a process plant so as to transmit it to the motor controller. The motor controller updates the set value of the control parameter relating to the control characteristics of the motor in accordance with the supplied updated value of the control parameter. The plant controller transmits the updated value of the control parameter to the motor controller in such a manner that the parameter code denoting the type of the control parameter and the updated value are allocated to predetermined bits of one word. The motor controller separates the received parameter code and the updated value from each other to change the setting of the control parameter, which corresponds to the parameter code, in accordance with the updated value.
