Hello, I am facing a problem with the analog output 6ES7 135-4FB01-0AB0 (0-10V 13bit) used with ET200s IM 151-1 Basic module. The problem is that the output voltage between QV+ and M ana is always at 16 V. Can anyone help me in this case? how do i have to use the outputs? and eventually send me a small program sample and maybe a scheme of the wiring (I am trying to control ac drives with the output) Thanks for help.
