Abstract

The invention discloses a programmable controller variable forcing method, system and device and a storage medium, and belongs to the technical field of automation. The programmable controller monitors whether the first forcing signal sent by the master control terminal is received or not in real time, so that after the first forcing signal is monitored, the forcing response operation is triggered according to the first forcing signal; the characteristics of function complication of the programmable controller and system deployment flexibility during operation of the programmable controller can be adapted through triggering of the first compulsory signal, variable compulsory action is started to be executed through the compulsory response operation, the variable value of a target variable in the programmable controller is changed according to the compulsory response operation, compulsory of the target variable is achieved, and the compulsory control accuracy of the programmable controller is improved. Therefore, according to the changed variable value, the user program in the programmable controller is executed, and the mandatory operation result after the user program is executed is sent to the main control terminal, so that the execution efficiency of programmable control is effectively improved, and meanwhile, the software design mechanism and process are simplified.

Description

technical field [0001] The invention relates to the technical field of automation, in particular to a programmable controller variable forcing method, system, equipment and storage medium. Background technique [0002] Programmable controllers are widely used in the modern industrial automation industry, and as the brain of industrial equipment and factories, they play an irreplaceable role in the field of modern industrial automation. As a key technology for PLC debugging, forcing technology has been widely used in the field of discrete, especially process control. In the process of automatic debugging, due to reasons such as uncompleted installation or failure of on-site sensors, instruments and other equipment, it is necessary to force some Variables are used to simulate the actual signal value on site, and complete the debugging and function verification of a certain program. Among them, the rewriting of mandatory variables can be done by adding mandatory logic interface...
