WAGO PLC - on Zenon 7 - what drivers are needed?

Dear forum
We use Zenon 7 to visualise our building automation systems. It mainly consists of Siemens S7 PLCs and and a number of KNX installations. One of the cooling system, however, comes with a WAGO PLC, 750-842. CoDeSys 2.3.9.7 was used to program the plc.
What driver and what lisence is needed to map the WAGO data points on Zenon 7? The PLC is on the same TCP/IP network. When I look through the list of drivers I come accross 3 versions of 3S drivers, namely Codesys Arti NG SloftSPS, Codesys Arti SoftSPS and Codesys SoftSPS, and in the Wago folder there is another 4 drivers, Modbus Energy, Modbus RTU and Open Modbus TCP, straton NG and straton driver. Unfortunately, their descriptions do not really help me in finding the appropriate driver and documentation.
I’d be grateful if anyone could point me in some direction.
I look forward to hearing from you.
Regards,
Martin
