Morning,

I'm trying to set up a zenon v14 application. The application communicate with a S7-1511 with the new firmware 4.0. This firmware allows to adjust several types of acces control, but I've disabled all of them. 

I can't get Zenon to communicate with PLC. All variables are "invalid". 

Although zenon engineering application is able to read and import variables from PLC.

Is Zenon compatible with 4.0 firmware PLC's of Siemens?

What am I doing wrong?

Thnks
