Claims6
A controller that can detect a loop process being stuck in an infinite loop during execution of a ladder program, the controller comprising:
- an infinite loop escape unit for escaping the infinite loop by forcefully making an execution condition for a jump instruction false when the infinite loop occurs, the jump instruction being included in the loop process.
An editor for editing a ladder program, the editor comprising:
- an infinite loop detection unit for recording an execution condition signal of a loop process that may cause the infinite loop, in an infinite loop occurrence condition information table.
