<div class="markdown_content"><h3 id="hello-there">Hello there</h3> <p>I need to know if there is any way to discover the IO Device only by IO address.</p> <p>For example, I know that %QW12 is used somewhere in the project, is there a library that allow me pass this address and retrieve the device or some usefull info?</p> <p><img src="./attachment/expansions.png" width="50%"/></p> <p>I found an interesting FB from library CAA Device Diagnosys called GetIDeviceInstByIoAddr, but I couldn't find out how to get it work, because whenever I execute the block it throws an error and by the way it doesn't show nothing more than a bit xError output for debugging.</p> <p>[-img src=FB Idevice.png width=50%: missing =-]</p> <p>What I'm trying to do, is basically a 'In runtime address discovery' to find every device that uses IO address mapping.</p> <p>Can someone help me? is something like achievable?</p></div>
