PURPOSE:To obtain a sequence controller capable of complicate, high-function interruption processing by providing a means which selects interruption operation corresponding to an interruption request and a means which decides on whether the interruption operation is allowed or not. CONSTITUTION:A microprocessor 2 confirms the generation of an interruption during sequence processing. If there is contact information for selecting whether an interruption program is permitted or not, the microprocessor 2 refers to an internal jump table generated in power-on operation and starts the corresponding interruption program to perform the interruption processing shown by a relay ladder circuit. When there is not said contact information, no interruption is allowed and a return to the original sequence control is made. |
