Server addresses
The OPC UA server of the S7-1500 CPU can be reached over all integrated PROFINET
interfaces of the CPU (firmware V2.0 and higher).
Direct access to the OPC UA server of the CPU over the backplane bus of the automation
system is not possible via CPs under the following conditions:
• Configuration with TIA Portal Version V16 or higher, S7-1500 CPU firmware version 2.8 or
higher and CP 1543-1 firmware version V2.2 or higher.
For configuration, see Access to OPC UA applications (Page 157).
Direct access to the OPC UA server of the CPU over the backplane bus of the automation
system is not possible via CMs.
With SIMATIC S7-1500 SW controllers, access to the OPC UA server is possible via PROFINET
interfaces that are assigned to the software PLC.
Additional access options of SW controllers are described in the following application
example: Internal and external OPC UA connection via the virtual Ethernet interface of the
software controller V2.5 or higher
(https://support.industry.siemens.com/cs/ww/en/view/109760541).
