PROGRAMMABLE CONTROLLER SYSTEM, TOOL DEVICE, TOOL PROGRAM AND RECORDING MEDIUM, AND PROGRAMMABLE CONTROLLER

摘要

Provided are a programmable controller system, a tool device, a tool program and recording medium, and a programmable controller, with which it is possible to improve utility for preventing unauthorized use of a user program which is executed on a programmable controller. In a programmable controller system (300), a tool device (200) sets a first user program execution ID (10) in a second non-volatile memory (113) which is disposed in a PLC (100), and sets a second user program execution ID (20) in a project (PR) which is disposed in the tool device (200). The PLC (100) queries whether the first user program execution ID (10) and the second user program execution ID (20) match, and prohibits execution of a user program (YP) if they do not match.
