Abstract

PURPOSE:To prevent the generation in malfunction surely, by simple grasp of the execution cycle time of control operation by the users, by providing the means counting the cycle time executing a series of operation and a display device for the count value. CONSTITUTION:A user's program memory 1, input/output memory 3, logical operation processor 4, and system working memory 5 are provided. The output status at an input/output circuit 2 is set in accordance with the input/output state at the circuit 2, by the processor 4 which repetitively repeats a series of operations consisting of renewal of input/output data in the memory 3, execution of the control program and of service operation of the system including the processor. A scanning type programmable controller of such operation is provided with a clock means 6 counting cycle time for the execution of a series of operation and a display 7 displaying the count value.
