<div class="markdown_content"><p>Hi,<br/> I have been working on Codesys V3.5 with PFC200 controller and Can Gateway 750-658. I want to convert the incoming CAN data from bytes into UINT and for outgoing data bytes to UINT. Does anyone has experience with this kind of data? I tried few different ways but it doesn't seem to be working. </p></div>
