Abstract

The invention provides a monitoring method and monitoring system of a programmable logic controller (PLC). The monitoring method is characterized by comprising the following steps: firstly generating a configuration file for a project, then verifying the configuration file, setting a user interface (UI) element and obtaining paths for equipment to carry out combined working; then obtaining equipment telegraphs corresponding to the paths; and finally selecting the stacker single automatic or combined automatic operation mode to complete the task. The monitoring system comprises a configuration module, a logic processing module, a main interface module and a system configuration module, wherein the configuration module is used for managing the configuration file; the logic processing module is used for verifying and analyzing the configuration file and generating the equipment telegraphs corresponding to the working paths; the main interface module is used for modifying the UI element and selecting the working mode; and the system configuration module is used for setting a database and the IP address of a camera. The monitoring method and the monitoring system have the following advantages: the reuseability is strong; the developing and debugging cycles are shorter; and the difficulty in electrical program development is reduced.

Description

Technical field [0001] The invention belongs to the field of automation equipment control, and specifically relates to a programmable logic controller (Programmable Logic Controller, PLC for short) monitoring method and monitoring system thereof.
