Programmable Logic Controller(PLC) board-level tooling test system, designed to test the single-board hardware connectivity and basic functions of N series PLC which was localized，it provided software support and verification for simple hardware design and problem locating. General board-level tooling test products whose testing environment was different for each board, even the manual operation was complicated that lead to human and material costs are too high. This paper provided a cross-platform PLC board-level tooling test method and system based on Qt, which was a automated test system for single-board PLC module function and interface. The results show that the system can increase efficiency and cut the cost greatly.
