And for good reason. Ethernet simplifies and homogenizes connectivity between industrial devices. We don’t have to worry about male or female DB9 and DB25 serial connectors, no concern for DTE or DCE devices, and forget about straight-through vs. null-modem cables. In general, the world is a much happier place. However, even with the added simplicity Ethernet offers, troubleshooting Ethernet networks can be a bit more involved than serial networks. Let’s assume you’re trying to establish communication with an industrial Ethernet device that for whatever reason has dropped off the network. Here are a few tips I always use when starting to troubleshoot an industrial Ethernet network.
