Hallo mattia22

YES WE CAN!

It is very simple to change the analog output value between 0..10 V DC using the Function Keys (F keys) of the LOGO! TD.

1) Use the F keys as inputs to a small circuit to increas or decrease an Up/Down counter.

2) You can make the Up/Down counter start at a 'middle value' or pre-defined value

3) You can improve the circuit so that the value increases faster if you hold the F key for longer

4) You can also limit the range of the value so that is does not go past 0 or 1000 (10,00 V)

5) Then you simply REFERENCE the counter value to an Analog Multiplexer (MUX) which has an analog output.

6) Wire the AM2 AQ analog output module for VOLTAGE (M1 & V1 or M2 & V2)

7) That is the solution.

8) See the linkto the sample code, courtesy of another Forum user (I forget who!)
