OPC UA Client for WinCC

Enables process communication of Simatic WinCC with OPC Unified Architecture Servers (data Access) via Ethernet TCP/IP and the OPC Unified Architecture binary protocol.

The Software package contains the channel-DLL (OPCUA.chn) and a browsing tool (UATags.exe), which enables the discovery of OPC UA Servers via the OPC UA Discovery Service to find OPC UA Servers in the network or specific machines. With the tool it’s easy to navigate through the address space of the choosen OPC UA Server and choose the node which then will be automatically added to the Simatic WinCC Project. The needed connections in the WinCC Tag Management will also be created automatically and will be parameterized due to the choosen endpoint.

The channel will take care of the sucscription and monitored item Management and will create and parameterized them according to the use of the tags in the Simatic WinCC Project. Of course single or multiple tags can also be read in C-/VBA-Scripts, like in other channels.

For an easy overview of the address space, the browser does also give the opportunity to read and write single variables.

This solution has full Support of security mechanism (Sign and SignAndEncrypt) as well as User Access Control. The entered username and password are stored encrypted in the project, so they won’t be needed when reactivating the project.
