AS-Interface is a topology-free network allowing the network cable to be routed in just about any shape desirable. Repeaters, and in some cases terminators, allow the creation of very large networks -- 1000 m or more.

AS-Interface gateways keep several data lists that are useful during commissioning and troubleshooting. These lists also play a role during the automatic node replacement procedure. Tim and Helge explain why these lists are important, how they can be accessed, and what the PRG enable LED means.

Continuing their discussion of AS-Interface gateways, Tim and Helge talk about mapping I/O into the PLC. Since gateways map this I/O into a fixed map, adding or even removing modules later is trivial. Specifically on EtherNet/IP, the I/O instances make it convenient for the programmer to define how much data a gateway...
