Hello. I have started Siemens SIMIT as OPC Server. Am running 2 clients, UAExpert and TW3. The thing is that i am only able to read the signals, not write to them (have tried turning the other client off). But the same signal can be written to by UAExpert.

Funny thing is also that when twincat asks about linking a variable, it suggests an input even though it is an output.

Any idea?

Cheers

After some searching i realized i had to write to 1 "execute" and "write enable" under controls.
