Hello Thomasth,

Sorry, for the moment i do not have the solution of the problème!! I have contact the driver seller and they gave me some way to follow, but nothing is working.

It seems that this problem come from  security settings on the PLC project and web service. Maybe you can try in this way!

I have a question :

Did you bought the driver or you are just running a demo version like me?

 

regards

Hello Tomasth.

I solved the problem, now it is working fine for me.

The problem is when you made modification on the plc settings, you need to compil the settings and transfer theses modifications!!

A the beginin i was thinking that when you modify the parameter it modify automatically on the plc, but not. All parameter settings need to be compil and transfer.

So you can apply all the settings given by the supplier on the screeshot, then compil and transfer.

After that it should work.

Let me know if it's ok for you.

Good luck
