I’m trying to set up communications between a new laptop and an existing AB PLC. The PLC has a 1756-ENBT/A Ethernet/IP module. In RSWho I get the yellow question marks and red X’s over the devices. I’ve tried pinging the Ethernet module but I get a message stating that the “destination host is unreachable”. I realize that this is a network problem but I’m stuck when it comes to fixing it. I can communicate with the PLC using our old laptop so I’m pretty sure the problem is in the setup of the new laptop. Any help would be greatly appreciated.
