ECx-4XX I/O Extension Module Addressing
Each ECx-4XX I/O Extension Module on a 2-Wire subnetwork data bus needs to be set to a
unique address. The address is set through the DIP switch located on the ECx-4XX I/O Exten-
sion Module's faceplate. The range of valid addresses is 1 to 7.
An example of how to set an ECx-4XX I/O Extension Module address DIP switch is shown
