Abstract
A programmable controller includes a master CPU for processing data in accordance with a predetermined program including a prescribed sequence of operating steps, a plurality of operating devices responsive to the master CPU, each having at least two operating states, a monitor device for displaying the execution state of a predetermined number of steps in response to batch processing by the master CPU, and a slave CPU. The slave CPU includes a command execution circuit for generating command output information in response to the execution of each operating step, a register for storing the command output information and the operating state of selected operating devices, and a counter for counting the predetermined number of executed operating steps in the sequence of the program.
