Abstract
In a programmable controller system, a sequence program, an operation sequence control program module and a plurality of I/O control program modules including interlock control are independently provided. In the interlock control of the start condition and the operation end condition of an actuator, an interlock condition set program is separated from the operation sequence control program, and the interlock condition is described in a table, thereby easily setting the interlock condition in the form of a table. As described above, when the operation sequence control program executed by a programmable controller and the input/output control program including the interlock control are independently provided, the number of steps in programming can be decreased, and reliability and maintenance performance of the program can be improved.
