OPC UA Server Development Technology Based on Domestic Industrial Control Configuration Software

Aiming at the problem of weak semantic information service ability of domestic industrial control configuration software, this paper studies the key technology of integrated application of industrial control configuration software and OPC UA, packages OPC UA server source code into functional blocks complying with IEC61131-3 international standard, on the basis of domestic AnyControl configuration software and its secondary development kit, and designs OPC UA information model creation module. Thus, OPC UA service can be opened through function blocks in configuration software and the OPC UA information model can be developed visually with low code. By verifying on Arm+Linux platform, this paper shows that the OPC UA service can be started quickly and a four-layer information model can be created by using the domestic configuration software. The OPC UA service function of the domestic industrial control configuration software is realized, which is beneficial for the industrial control system and software developers to quickly master the development technology of OPC UA.
