Product Overview
The Omron CP2E-N40DT-D is the 40 I/O head of the CP2E-N slim network PLC line. It is manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports. Specifications on this page were checked against Omron's CP2E dimensional table and product page.

Best-Fit Applications
- Multi-station assembly machine where each station is a CP2E-N on the same network
- OEM skid with a CP2E-N plus one CP1W analog option board for a pressure / flow loop
- Conveyor cell with 4-axis encoder feedback and 2-axis stepper / servo control
Buying Checklist
- Pick CP2E-N60DT1-D instead when 60 I/O with PNP sourcing outputs is the requirement.
- Pick CP2E-N30DT-D instead when 30 I/O is enough and a slightly smaller body fits the cabinet.
- Pick CP2E-S30DT-D instead when the machine does not need factory Ethernet and one Ethernet port is enough.

FAQ for CP2E-N40DT-D
What is the difference between CP2E-N40DT-D and CP2E-S30DT-D?
Ethernet ports and I/O count. The CP2E-N40DT-D is the dual-Ethernet network head with 40 I/O (24 inputs / 16 NPN sink outputs). The CP2E-S30DT-D is the slim single-Ethernet head with 30 I/O. The N40 head costs more but carries the second Ethernet port for SCADA + HMI on a daisy chain, plus a larger program capacity (10K steps vs 8K on the S30). Pick the N40DT-D for networked machines; pick the S30DT-D for stand-alone machines that only need one Ethernet port for an HMI.
How many expansion units can I add to a CP2E-N40DT-D?
Up to 3 CP1W expansion units for a maximum of 160 I/O total (40 built-in plus 3 x 40 I/O expansion). The 40 I/O expansion units are CP1W-40EDR (24-in / 16-relay-out), CP1W-40EDT (24-in / 16-NPN-out), and CP1W-40EDT1 (24-in / 16-PNP-out). The CP1W-8ET / 8ET1 (8-point output), CP1W-16ER (16-point relay), and CP1W-AD042 (4-point analog) are smaller alternatives. The CP2E-N40DT-D also has 1 CP1W option board slot for a serial port or analog channel on the front face.
Is the CP2E-N40DT-D programmed with CX-Programmer?
Yes. CX-Programmer version 9.6 or later supports the CP2E family with ladder logic, structured text (ST), and function block (FB) programming. CX-One is the bundle that includes CX-Programmer plus the network configurator. The CP2E series shares the same instruction set as the CP1E and CP1L families, so existing CP1 ladder programs move to the CP2E with minimal rework. Sysmac Studio does not support the CP2E -- the CP2E is the CX-Programmer platform, not the Sysmac NJ / NX1 / NX5 platform.
Does the CP2E-N40DT-D have a battery-backed clock?
Yes, but the battery is sold separately. The CP2E-N40DT-D has a real-time clock (RTC) for time-stamped events, scheduled outputs, and astronomical timer instructions. The CP2W-BAT02 battery (sold separately) is required to keep the clock running when the 24 VDC supply is off. Without the battery, the RTC resets on every power cycle. The S and E heads do not have the RTC at all. Add the CP2W-BAT02 on the build sheet when the application uses time-of-day logic or scheduled events.
