1788-CNC is an Allen-Bradley ControlNet daughtercard designed for compatible FlexLogix, DriveLogix, and supported daughtercard hosts.
Its coax interface connects through an approved tap and provides module, I/O, and network-status information together with temporary NAP programming access.
Before installation or replacement, verify Series, firmware, host support, node address, channel-A connection, tap, cable, termination, network schedule, and keeper records.
