hi all
i use a analog output module +-10 volt but i need 0-10 volt for control valve actuator
can i exchange output(+_10 volt to0-10 volt) in plc softwear?
my base unit is twido and my analog module is 2HT
I'm not familiar with the Twido, but it would apear a quick solution would be to limit your output to 50%, corresponding to 0 VDC. You would loose resolution, but the output probably has more resolution than the valve anyway.

As stated, you can simply set up your scaling for 0 - 10V... If you desire, you could also add a line of code, that if the output is less than zero... Move zero to output.
in S7-200 Plc for example,if i want 10V output i move 32000 value in the output address,if i want 5V than 16000 and 0 than it should be 0.
i dont know how you can vary the output in twido.
