Analog Module Setup Question - Q68DAVN

2 posts in this topic

I need to set up D/A module. I have few questions. What is the difference between offset and gain setting mode? I would like to use range 0 to 10V which would have to be set as user range setting, can I do it using GX Works 2? Or do I have to use the GX Configurator-DA package?

If you have GX Works2 all settings can be done there, no further need for the configurator software. Offset and gain adjust mode is to fine tune the scale of the input, such as if your scale is actually not perfectly 0-10V. You should not need to use it. But if your device is really only putting out 0-9.5V and you want the full scale reading, the gain can be adjusted to fine tune it. I never do offset/gain adjustment, I just make my code match the actual input. There are very easy ways to scale a numeric value.
