Hello. I have problem, with analog output card Simatic AO 8x 12 bit 6ES7-332-5HF00-0AB0. I m using all 8 outputs with 0-20mA.I have disconnecded all outputs and start measuring. First output is doing well, but other 7 are behaving strange...for example, when output on all channels shoud be 0, I have on first channel 0mA, but on second -1,5mA and so on(its nothing wrong with software, because Im sending the same signal on all outputs)....Does this mean there is something wrong with card? I have also checked modul information, and nothing there. Any idea? Thx.
