Title:
COMPUTATION UNIT, OUTPUT CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/124144
Kind Code:
A1
Abstract:
In the present invention, the CPU unit of a PLC executes motion control and sequence control. The CPU unit stores: a control program for executing motion control using a CAM table; and a first CAM table and second CAM table. When a microprocessor receives a predetermined instruction during execution of the control program, the microprocessor switches the CAM table used in the execution of the control program from the first CAM table to the second CAM table. On the basis of the switching of the CAM table, the microprocessor outputs the execution results of the control program using the second CAM table to an apparatus to be controlled.
