Abstract

The invention provides a method and a device for polling IO (Input / output) modules, a storage medium and an electronic device. The method comprises the following steps that: a main control module sends a first polling request to the first IO module, wherein the main control module is connected with a first data bus and a second data bus simultaneously, and the first IO module is connected with thefirst data bus; while waiting for feedback data from the first IO module, the main control module sends a second polling request to the second IO module, wherein the second IO module is connected with the second data bus. The problem of low efficiency caused by too long polling time in a PLC system in a related technology is solved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a polling method and device for an IO module, a storage medium, and an electronic device. Background technique [0002] In the application of the safety programmable logic controller (Programmable Logic Controller, referred to as PLC) system, the running state of the safety PLC system needs to poll the information of each input and output IO module in each cycle. This stage is called IO bus polling ( IOBUS Polling) stage; in order to improve the response time of PLC, it is necessary to shorten the operation cycle, most of the equipment cannot shorten the time in the IOBUS Polling stage at present. [0003] In the related art, there is no better solution to the problem of low efficiency caused by too long polling time in the PLC system. Contents of the invention [0004] Embodiments of the present invention provide a polling method and device, a storage medium, and...
