Hello,

there is no direct way to use OPC UA protocol with LOGO!

The LOGO! only supports S7 and ModbusTCP as communication protocols.

Therefore you do need a S7/Modbus <----> OPC UA Gateway.

From Siemens you can use this industrial gateway -6GK1411-1AC00 Simatic Cloud Connect 7, CC712, depending on the level of your application (privat or business)

There all functions you need are already included.

You can also build the gateway yourself with an IOT2040 from Siemens and other small application IOT Boards. Most of them can install a S7 and OPC librarys.

An other way could be to use the cloud function with LOGO! 8.3 into AWS. From AWS it should be possible to get the data to an OPC Server.

Best greetings
