Port DeviceNet block

These blocks offer 14 DeviceNet nodes in footprints that are the same or smaller than existing 8-port blocks. When they're combined with ultra-thin DeviceNet cordsets, more connections can be put into a single trunk cable connection. The cordsets enable an M8 male connector to be connected to the passive network block with an M12 female connector for interfacing with DeviceNet field devices, which allows users to have a high-density intercom system without changing existing devices.
