CODESYS OPC UA

Standard Interface for Communication in Smart Factory and Industry 4.0 Systems

Platform Independent Standard Access to Variable Data

OPC UA (Unified Architecture) is a new development of OPC specifications which allows not only for transportation of machine and plant data but also for a semantic description of these data in a machine-readable way. OPC UA is a platform independent standard based on TCP. The protocol stack is available for all members of the OPC Foundation. The OPC UA specification provides different profiles for the scaling of individual features.

Overview CODESYS OPC UA Server

  • Implementation of the communication according to the OPC UA specification using  the profile "Micro Embedded Device Server", based on the communication stack of the OPC Foundation
  • Additional component to the CODESYS Control Runtime System for device manufacturers as an alternative to the CODESYS Control Runtime Toolkit. Can be implemented in all device platforms with sufficient performance and existing TCP/IP stack and real-time clock supported by CODESYS
  • Already included in the CODESYS Control SoftPLC systems available in the CODESYS Store (without additional license fees)
  • Provision of data about the symbol configuration in the CODESYS Development System
  • Communication with any OPC UA client

Overview CODESYS OPC UA Client

  • Additional component to the CODESYS Control Runtime System for device manufacturers as an option to the CODESYS Control Runtime Toolkit
  • Allows for the implementation of different clients in all device platforms supported by CODESYS with sufficient performance, existing TCP/IP stack, and real-time clock
  • Support of all available functions in the CODESYS OPC UA Server
  • Currently realized as library function
  • First release with CODESYS V3.5 SP16
  • Under development:
    • Integration into the CODESYS Control SoftPLC systems available in the CODESYS Store
    • Integration of a convenient configuration interface for the CODESYS Development System

Howtoget

  • You are a system integrator or a user in the machine/plant construction sector or the like:
    • Apply controllers which are already equipped with the CODESYS OPC UA Server.
    • Purchase SoftPLC systems from the CODESYS Store which include the CODESYS OPC UA Server without additional license fees.
  • You are a manufacturer of programmable devices:
    • Purchase the CODESYS OPC UA Server and use the CODESYS Control Runtime Toolkit to implement the additional components delivered in your device. In order to do so, integrate the source code of the OPC UA communication stack available for all members of the OPC Foundation.
