{{DISPLAYTITLE:IBH OPC UA}}
The '''IBH OPC UA Server/Client''' is a 64-bit software solution for Windows and Linux PCs. It connects controllers and devices to OPC UA, provides an integrated OPC UA Client and is administered through a Web Configurator.

The software variants for Windows, Linux PCs, IOT2050 and RevPi use the product name '''IBH OPC UA'''. The dedicated hardware products continue to use the established name '''IBH Link UA'''.

== Core functions ==
=== Optimized data blocks for S7-1200 and S7-1500 ===
The enhanced S7CommPlus driver directly accesses optimized data blocks of current SIMATIC S7-1200 and S7-1500 controllers. Read and write operations, sampling and subscriptions are designed for high performance, balanced load and stable continuous operation.

=== Python, NodeSets, methods and data models ===
Python 3 can be used to integrate custom scripts, variables, OPC UA methods and information models. On Windows, Python runs in a separate host process.

XML NodeSets and data models are also loaded without Python. Types, variables, methods and references remain visible; only Python callbacks are not executed. Python methods return <code>BadNotSupported</code> in this case. The '''Nodeset''' menu remains visible and clearly indicates that Python is not installed.

=== OPC Classic on Windows ===
The optional OPC Classic Gateway exposes the OPC UA address space as OPC Data Access 2.0/3.0. Both 32-bit and 64-bit OPC Classic clients can access the native 64-bit server. Remote DCOM can be enabled as a separate setup option when required.

=== Security and certificates ===
OPC UA security policies, signed and encrypted connections and central GDS integration support secure operation. GDS functions include application registration, certificate renewal and Trust List management.

* historical data
* MQTT connectivity
* integrated S7 SoftPLC
* web-based administration, diagnostics, backup and restore
* configuration with the free [[IBH OPC UA Editor]]
