The AN-X-Mod gateway can be used in a redundant scanner application with the following considerations:
1) They cannot operate on completely separate S908 networks. They need to share the same physical media so that they are able to monitor the network for the presence of a Scanner.
2) The AN-X-Mod gateways have built-in termination so they need to be connected to the Modicon splitter.
3) It can be used in a regular ControlLogix application or in conjunction with a redundant ControlLogix application.
