Embedded OPC UA server/client with integrated firewall for SIMATIC, Mitsubishi and Rockwell controllers. It is a compact device for DIN rail mounting with two 1Gbit Ethernet ports and a 24V power supply.
The IBH Link UA Quad Core 64 Bit is a much more powerful device for demanding applications, as it works with a 64 bit 1.8 Ghz processor with 4GB RAM.
(For comparison: The IBH Link UA Quad Core 32 Bit works with a 32 Bit 1 Ghz processor with 2GB RAM.)
Furthermore, the IBH Link UA Quad Core offers the possibility to extend the functionality with Cloud Services by using an SD card.
MQTT connection:
User-defined OPC UA variables can be exchanged with an MQTT broker/server.
The IBH Link UA can therefore be used as a layer between machines and control systems (MES, ERP…) independently of controllers.
Support of data models and methods with Python:
To link data models or companion specs with Python modules on the IBH Link UA, the desired companion spec or data model is integrated into the project on the IBH Link UA. The OPC Foundation has specified data models for a variety of industries. For industrial automation, for example, there are data models for the automation of production plants and machines, such as machine control, monitoring and diagnostics, as well as production process management and energy management. This means that all the possibilities offered by Python can be used.
GDS – Global Discovery Service (Server/Client):
A Global Discovery Server (GDS) provides mechanisms for the central administration of the following components:
• CA-signed certificates and self-signed certificates
• Trusted lists and certificate revocation lists (CRL)
A GDS thus provides an access point for central certificate management.
It therefore takes on the role of a security server within an OPC UA network.
Optionally, it is possible to install a GDS server from Unified Automation as a Docker container.
