It worked great in the simulation! Tomorrow i'll install it in real.

many thanks! grtz

Hi there,

it's been a time but due to overload of work I wasn't able to try the program out earlier. I still have the same problem as before. The logo! doen't react on the pressure transmitter. The value on the screen stays at 0.004 and 0.008 despite moving the transmitter up and down in the water. The incoming voltage varies from 0 V until 4,5 V if 1.8 m deep in tank. So that's normal since the transmiiter scales from 0 to 4 m. 

For one reason or the other the signal is not recognized by the Logo! ? I connected the 2 signal+ wires to I1 and I2.

Any clue anyone?

 Hello 

AI1 and AI2 corresponding to the input terminals I7 and I8, not to I1 and I2 in your circuit program.

 Have a look under "File->Properties" and then click I/O settings, there you can enable 2 or 4 AI's.

There is also a good explaining text in that dialog box.

Thanks, it says if 2 Ai's are enabled to put them on I7 ad I8. didn't know that.

I'll try.
