Problems solved by technology

At present, this kind of signal simulation debugging is usually to establish signals in the simulation environment and add signal logic, but due to the limitation of simulation software, this method can only manually create signals one by one, adding signal logic is also relatively simple, and the signals cannot be classified, debugged and managed in a centralized manner.
When the PLC program is changed, the signal update is also very inconvenient

Abstract

The invention discloses a method for specifying signal simulation debugging in a virtual debugging system. The method comprises: step one, a signal corresponding to a manual part feeding operation isestablished in a simulation environment and the signal is outputted; step two, fault, upper computer initialization, and regional interaction signals are outputted in a PLC writing environment; step three, a signal list for an EXCEL file is established newly, and a station, a signal type, and a signal initial value are added; step four, connection parameters of an OPC server are set and signal interaction is carried out on PLC hardware and a digital production line in the simulation environment; step five, a signal list is inputted and a project file in a specific format is generated; and stepsix, signals are displayed in a visualization interface based on locations of the station in different areas and the displayed signals are debugged. The method having high versatility and interactivity is a method that can be used comprehensively and conveniently and is used for specified signal debugging of part feeding operation, fault and initialization based on a virtual debugging system.

Description

technical field [0001] The invention relates to a signal simulation simulation method in the field of virtual debugging, in particular to a designated signal simulation debugging method in a virtual debugging system. Background technique [0002] The virtual debugging system is an electrical debugging technology based on digital simulation technology. Through the combination of simulation environment and physical PLC, HMI and other automation equipment, the joint debugging system of PLC program and robot program is completed. [0003] OPC protocol: (OLE for Process Control OLE for process control) industrial communication protocol. [0004] In the virtual debugging system, signal simulation is a very important debugging content, especially in the robot automatic production line, there are hundreds of faults in the signals of each PLC area, the initialization signal of the upper computer and the start signal of the manual loading part, and the signal debugging of this part...
