Compact machine controller with twin-fieldbus connectivity
The NX1P29B40DT1 is a DIN-rail or panel-mount PLC packing 24 digital inputs and 16 transistor-sourced outputs at 24 V nominal. Built-in EtherCAT and EtherNet/IP remove the need for separate gateway modules, cutting cabinet space and component count. Cycle time sits at 2 ms, with 1 MB of program memory and 2 MB of data memory — enough for a mid-size pick-and-place or packaging machine with cam profiles. Motion control via EtherCAT handles up to 2 point-to-point axes and 1 coordinated path without an extra motion controller. Push-in terminals on the base unit speed wiring; an SD slot holds program backup or data logging. A battery-backed real-time clock keeps time-stamps accurate across power cycles.
Peer comparison: NX1P2-9B40DT1 vs NX1P29B40DT1
The alternate order code NX1P2-9B40DT1 carries identical headline specs — same 24 DI, 16 DO, 2 ms cycle, 1 MB program, twin-protocol networking, and same 2-axis motion capability. Both mount on DIN rail and use push-in terminals. The two part numbers are functionally identical; no rewiring is needed for substitution.
Integration and expansion options
Base unit accepts up to 8 local NX-series I/O slices, reaching 296 points local, or up to 808 with an NX coupler. Maximum total units per CPU is 24. The built-in EtherCAT master handles servo drives and remote I/O nodes. Ethernet/IP serves HMI, SCADA, or higher-level controllers.
