Embodiment Construction

[0034] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0035] Such as figure 1 Shown, the monitoring method of PLC of the present invention specifically comprises the following content:

[0036] Step 1: Generate configuration files. The generation process of the configuration file in the present invention is: on the graphical interface, the user combines the graphics representing the three-dimensional warehouse equipment by dragging and dropping the graphics according to the quantity of the three-dimensional warehouse equipment and the logical relationship between the equipment, and fills in the Or select the properties of each device to complete the configuration file generation. Such as figure 2 as shown, figure 2In , the figure of the pile with a square box indicates the stacker, the double-headed arrow indicates the conveyor, the direction of the arrow indicates the running direction of the conv...

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 configurationmodule, 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 moduleis 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 in particular relates to a monitoring method of a programmable logic controller (Programmable Logic Controller, PLC for short) and a monitoring system thereof.
