  • Associated product(s)
As of firmware version V2.5 and TIA Portal V15, the SIMATIC S7-1500 control system also offers OPC UA methods for the clients via its integrated OPC UA server.

For standardized, communication of an S7 control system that applies to all platforms and manufacturers, Siemens offers you the communication protocol OPC UA.

As of firmware version V2.5 and TIA Portal V15, the SIMATIC S7-1500 control system can also offer OPC UA methods for the clients via its integrated OPC UA server. With this addition to the functions, you not only have the option of reading or writing OPC UA variables of the control system, you can now also start complex functional sequences via OPC UA. This enables almost complete M2M communication via OPC UA, for the networking of plants or for the control of plants from an ERP / MES level.

In this application example, we explain how to program an S7 function block so that it can be called as an OPC UA method on the server of an S7-1500.
