Hello SIOS Forum Community, In the course of digitalisation, OPC UA is increasingly establishing itself as an important communication standard, which is also being used more and more in the immediate environment of PLC controllers. In addition to the OPC UA functions, the possible access paths are of particular interest. The available access paths for the SIMATIC S7-1200 and S7-1500 controllers are shown below. In addition, solutions are presented as to how access via OPC UA is also possible for older existing systems with SIMATIC S7-300 and S7-400 controllers without integrated OPC UA functionality. Please note that not all available OPC UA functions (client, server, access methods, e.g. Companion Specification, etc.) are discussed in this article. Information on the available OPC UA functions can be found in the manuals of the respective products. Available access paths for the integrated OPC UA functions by controller type: 1. Basic controller (SIMATIC S7-1200, FW version from 4.4) Access only available via the integrated PROFINET interface 2. Distributed controller (SIMATIC ET200SP/ ET200PRO FW version from 2.0) Access only available via the integrated PROFINET interface! 3. Advanced controller (SIMATIC S7-1500 FW version from 2.0) Access available via the integrated PROFINET interface(s) and also via CP 1543-1 from V2.2. " IP accessibility for S7-1500 CPUs via communication processor CP 1543‑1 V2.2: OPC UA server and client of S7‑1500 CPUs can transfer data using a CP 1543‑1 V2.2. The functionality can be enabled for a CP 1543‑1 V2.2 communication processor with disabled security functionality in the SIMATIC S7-1500 system by configuring the virtual CPU interface."

Frequently used systems for external OPC UA functions a) SIMATIC NET PC software e.g. SOFTNET S7 IE Lean(PC system required)
b) IoT Gateway SIMATIC Cloud Connectors CC7
c) SIMATIC Comfort Panels with integrated OPC UA Server
