<div class="markdown_content"><p>Hello, </p> <p>I'm trying to connect to a Keyance CL-P015N Optical unit, used with a CL3000 sensor. After configuring, I do not see any connection errors on the Log (I get "IOdrvethernetIP configuration successfully completed. Start communication"), but there seems to be no signal from the sensor.</p> <p>I have tried playing around with the connection parameters which helped me establish a connection with other Ethernet Drivers but it doesn't seem to work here. Any ideas why this might be happening? I'm able to connect with the sensor through Keyance's software via ethernet - so I know that part is working. Can't seem to do it through Codesys. </p> <p>Thanks in advance !</p></div>
