It carries integrated EtherCAT and EtherNet/IP ports, an SD-card flash memory slot, and a programming connection over USB or Ethernet. Programming is Ladder, Structured Text, or Function Block; motion control runs over EtherCAT, with 0/0/0 axes on this CPU variant. ## Cross-shop: NJ101-9020 vs NJ301-1200 The closest functional sibling in the Sysmac NJ line is the NJ301-1200, which is the next step up the same family. ## Sourcing posture Mounting is DIN rail, so the unit drops into the standard Sysmac NJ cabinet footprint without a subpanel cutout; size the cabinet for the expansion headroom of up to 40 units per CPU if the cell is distributed. Both EtherCAT and EtherNet/IP are on-board, which removes a separate coupler from the bill and leaves the fieldbus slice to one CPU module plus its slices. Programming port is USB or Ethernet, so the commissioning laptop connects without a dedicated serial cable — keep a known-good USB cable in the panel spares kit because that path is what carries the first download.","metaTitle":"Omron NJ101-9020 NJ1 CPU, 1 ms, 3 MB, DIN Rail","metaDescription":"Omron NJ101-9020 Sysmac NJ1 CPU with 1 ms cycle, 3 MB program memory, EtherCAT and EtherNet/IP, 2,560 local I/O.
