AllenBradley Communication Module Types

What scenarios to use the different communication modules is a sore topic for me. When to choose between the ControlNet, DeviceNet, and Ethernet modules; down to their integration into the system.

It’s a good question.

At this point, I’d only use EtherNet in all plant projects. ControlNet and Device net had their place before EtherNet became reliable and widely adopted by distributors.

That being said, ControlNet and DeviceNet are still widely used in plants all over the world and we’re planning to release content on how to use them effectively, how to interface with them, etc.
