Method for preferentially setting data of local 485 communication equipment

Abstract

The invention discloses a method for preferentially setting local 485 communication equipment data, and relates to the technical field of data communication. The method comprises the following steps:S1, submitting a special instruction to a local upper computer; s2, enabling the upper computer to immediately read the information of the specified equipment and return the information; s3, enablinga remotely setting program to use the special instruction to achieve setting sending; s4, enabling the user to continuously send the instruction through the upper computer to observe the change process of the target equipment; and S5, when the change process reaches a predetermined purpose, enabling the upper computer to stop sending the instruction. By setting a special instruction for the localupper computer, the upper computer can immediately read the specified equipment information when the instruction is submitted, and a user continuously sends the instruction until the target equipmentreaches the preset purpose, so that the user can conveniently observe the target equipment, and the equipment debugging efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of data communication, in particular to a method for preferentially setting data of local 485 communication equipment. Background technique [0002] Since the local upper computer adopts 485 communication, each time when setting data or reading data to the lower computer, polling will be performed once or multiple times, and the local upper computer will poll and read all the lower computers. It is to view and set the data transmitted from the local host computer through a browser or other software. When the remote management terminal needs to set the lower physical device, the local upper computer program will immediately transmit the setting information to the target lower device after receiving the setting request, and return the instruction result. However, whether the lower device has successfully accepted the setting command or whether the setting purpose has been achieved can only be finally determin...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for preferentially setting local 485 communication device data. By setting a special instruction for the local host computer, the host computer can immediately read the specified device information when the instruction is handed in. The user can continue to send instructions Until the target device reaches the preset purpose, it solves the problem that the existing device does not accept multiple polls and the observation of target device changes is troublesome
