<div class="markdown_content"><p>Hi, </p> <p>I'm using a Raspberry Pi 4 in combination with a Siemens ET200SP, but here's the problem:<br/> My the value of my input is only updated at +- 4 Hz, while my Profinet IO task is running at 4 ms interval, as are all my other tasks.<br/> If i let an analog output card send a sine wave directly to the analog input card, the trace shows a delayed signal with big jumps.<br/> I have checked the output signal with an oscilloscope, end the output is exactly as it should be. <br/> Also directly outputting the input signal again gives the same "blocky" signal on an oscilloscope.<br/> can anyone help me to get my input values updated at a higher rate?<br/> Thanks, <br/> Marnix</p></div>
