Abstract
A modular I/O system for an industrial automation network includes a network adapter including first and second adapter modules, wherein each adapter module is configured for connection with an industrial network. The I/O system further includes a first I/O device with first and second I/O modules each configured for operative connection to a controlled system for input/output of data with respect to the controlled system. The I/O system further includes first and second independent backplane data networks that connect each of the first and second adapter modules to each of the first and second I/O modules. The network adapter includes first and second removable backplane network switches and the first I/O device includes third and fourth removable backplane network switches that establish the backplane networks. The backplane network switches can be Ethernet gigabit switches.
