<div class="markdown_content"><p><em>Originally created by:</em> crthomas1234</p> <p>If I have a V3 PLC that I know is at a defined IP address, what is the best way to connect to that controller with PLC Handler? The V3 connection methods seemed to be limited only to the device name or CoDeSys address. Both of these will change from device to device but the IP is fixed on every controller.</p> <p>Is there a way to resolve a device name or address from the IP address?</p></div>
