Hi everybody.

I faced a problem with analog output module 6ES7135-4FB01-0AB0 that drives a 0-10V signal to FESTO proportional valve.

FESTO module has a pair of terminal for power supply and a pair for the signal (so I supposed that the input signal is isolated from the power supply. No tell clearly on Festo instruction manual).

So I connectthe Siemens module in the follow manner:

terminal 1 (Q+) and 2 (S+)-> Signal +(Festo)

terminal 3 (Mana)and 4 (Sense-) -> Signal-(Festo)

In that mannerI can't see a voltage variation on module based of the command.

I mustreferenced all the - signal to my 0V? Thanks.

The module is located in the red circle. Tks

Solved. No problem at the hw side. I made a silly mistake on sw. Instead writing PAW316I used a symbol named AW316. So my peripheral addressingdoesn't reach the analog module.

It's always apparently a simple answer towhat we think abig problem.

Thanks your your replies.
