Problems solved by technology

However, the current programmable logic controllers do not have a visual interface without exception, and usually the programs are pre-written on the computer, and then imported into the PLC for debugging, and online debugging cannot be performed; in the actual debugging process, once found Abnormal situation, the debugger has no way of knowing the exact location of the abnormal situation in the program, which brings great inconvenience to the correction work of the program. In most cases, it may be a small problem that is easy to solve, but it makes debugging difficult. The personnel are distracted and overwhelmed, which takes a lot of energy and debugging time of the debugging personnel

Description

technical field [0001] The present invention relates to programmable logic controllers or PLCs. Background technique [0002] At present, PLC (Programmable Logic Controller) has been widely used in various industrial controls, and its convenient and flexible control methods have been generally recognized. However, the current programmable logic controllers do not have a visual interface without exception, and usually the programs are pre-written on the computer, and then imported into the PLC for debugging, and online debugging cannot be performed; in the actual debugging process, once found Abnormal situation, the debugger has no way of knowing the exact location of the abnormal situation in the program, which brings great inconvenience to the correction work of the program. In most cases, it may be a small problem that is easy to solve, but it makes debugging difficult. The personnel were distracted and overwhelmed, and it took a lot of energy and debugging time for the d...
