Ciao Lambert_86. Yes I followed procedures. Here some details.


EUROTHERM1.JPG

When I chose the server I can see it properly.

When I add new variable, after choosing it I found the first error: EUROTHERM2.JPG

EUROTHERM3.JPG

I can solve this problem by manually choosing the variable:

EUROTHERM4.JPGIt is esactly the same variable in the same directory.

The Vi for reading variable:

EUROTHERM6.JPGAfter running Vi:

EUROTHERM7.JPGAnd value is always 0.

using Data socket i can read it properly:

EUROTHERM8.JPG

But I think the most usefull information is the Server diagnostic report: it is in italian but i suppose you can read it.

With server explorer i can read the same variable properly.
