Abstract

The invention discloses PLC reserved open type communication interface processing. The operation steps of PLC reserved open type communication interface processing comprise communication data configuration, human-computer interface editing, configuration information writing and PLC serial port data writing, so as to configure an open communication interface. The arrangement can reserve a communication interface at a batch project in use; through the arrangement, the programming amount can be reduced, and the workload can be reduced, and the work efficiency is improved, and an upper computer information management platform can process problems conveniently. According to PLC reserved open type communication interface processing, an open communication configuration format is adopted, so thathuman-computer interface resources can be effectively called, thus being simple and convenient to use; and usage of the open type interface is safe and reliable after a long time of testing and operating; and the problem of inconvenience in use due to the fact that programs need to be modified and a PLC (programmable logic controller) needs to be replaced when communication station numbers are repeated and conflicted can be greatly solved by the aid of the open type interface.

Description

technical field [0001] The invention belongs to the technical field related to reserved communication interfaces, and in particular relates to processing of PLC reserved open communication interfaces. Background technique [0002] With the continuous intelligent upgrading and application in the field of automation, as well as equipment big data management, currently relying on the man-machine interface to cooperate with the PLC serial port, configure (MODBUD RTU) communication interface, and the PLC serial port signal feeds back to the upper computer user management platform. [0003] The existing traditional technology for processing reserved communication interfaces has the following problems: when writing programs, the reserved interfaces can only be configured with fixed communication format data, such as baud rate, station number, check digit, etc., and the number of programs operated in this way is relatively large Many, and in the process of online debugging with the ...
