Abstract

PURPOSE:To attain extremely flexible control by allowing a master computer to switch an electric control operation mode to manual mode during the period of control operation and allowing an instrument control programming device to change and correct a measurement control memory while continuing the operation of an electric controlled system. CONSTITUTION:At the time of changing the set point of a water level by the programming device 4 for controlling the calculation of the master computer 1 during the operation of a controller 7 and changing and correcting the contents of the slave controller 7, the operation mode is switched from an automatic mode to a manual mode by an operation part 3 in the CPU 1. During the electric control operation of the controller 7, remote loading to the instrument control memory 10 is executed by the computer 1 and the set value and a program are changed, so that the operation can be continued without stopping the slave controller 7. Thereby, the functions of ordinary microcontroller and sequence controller can be attained only by one function.
