Setting up your IP address and subnet.
Have you ever found yourself asking “Why can’t I connect to this darn Allen Bradley Controller (MicroLogix, CompactLogix, ControlLogix) or Variable Frequency Drive (PowerFlex 525, 40, 70, 700, 755) over Ethernet”?
One of the most common mistakes I see is the PC’s network adapter is setup for DHCP and/or the device’s IP address and subnet have not been configured.
Most PC’s network adapters are setup for DHCP by default and need to be this way to connect to a majority of company and home routers. To connect to Allen Bradley Ethernet enabled devices your PC’s network adapter needs to be setup to have a static IP address on the same subnet as the device.
