Product Overview

The Omron CP2E-N40DT1-D is the 40-point network-type variant of the CP2E-series compact PLC. 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.

It runs on 24 VDC, holds 20K steps of user program and 16K words of data memory, and carries two built-in 10/100 Ethernet ports with a switching function for machine-to-machine communication. The 40 built-in I/O points break down to 24 DC inputs and 16 PNP sourcing transistor outputs.

The 4-axis linear interpolation works with any stepper or servo drive that accepts pulse + direction inputs at 100 kHz or below. Key specs: Model CP2E-N40DT1-D; Supply Voltage 24 VDC, 20.4 to 26.4 VDC operating; Digital Inputs 24 DC inputs (6 x 100 kHz high-speed counters); Digital Outputs 16 PNP sourcing transistor outputs; Program Memory 20K steps + 16K words data, LD 0.23 us execution; Communication Dual Ethernet (10/100 with switching) + 2 option-board slots; High-Speed Counters 6 inputs at 100 kHz (incremental, up/down, pulse+direction, 4x differential-phase); Pulse Outputs 4 axes at 100 kHz with linear interpolation.

Key Features

  • 4 pulse outputs at 100 kHz with linear interpolation
  • 6 high-speed counter inputs at 100 kHz (differential-phase, pulse+direction, up/down)
  • 20K steps program + 16K words data, LD 0.23 us execution, function-block programming
  • CP2E network-type compact PLC, 24 VDC supply, 24 DC inputs and 16 PNP sourcing outputs
  • SKU: CP2E-N40DT1-D
  • Series: CP2E network-type compact PLC
  • Voltage: 24 VDC

Best-Fit Applications

  • Multi-station assembly cell linking each CP2E to a cell controller.
  • Retrofit of older CP1L-N40 applications needing Ethernet but not CJ2M-class CPU.
  • Small packaging machine with 4-axis pulse positioning for indexing conveyors.

Buying Checklist

  • Confirm the output polarity is PNP - for NPN sinking loads, pick CP2E-N40DT-D instead.
  • Choose CP2E-N60DT1-D (60 I/O) when the cabinet needs more built-in digital I/O without an expansion rack.
  • Choose CP2E-S30DT-D for a basic-type CP2E without Ethernet - half the price when networking is not needed.

FAQ for CP2E-N40DT1-D

What is the difference between CP2E-N40DT1-D and CP2E-S30DT-D?
The N40DT1-D is the network-type variant with dual Ethernet, 6 high-speed counters, 4 pulse outputs with linear interpolation, 20K steps program and 16K words data. The S30DT-D is the basic-type without Ethernet, with fewer counters and no linear interpolation. Pick N40DT1-D for networked machines and small-positioning skids; pick S30DT-D for standalone machines that just need local I/O.
Does the CP2E-N40DT1-D need a battery?
No - the CP2E uses battery-free non-volatile MRAM for program and data retention, plus a built-in real-time clock. There is no scheduled battery replacement. An optional CP2W-BAT02 battery adds longer retention for applications with long power-off periods, but it is not required for normal operation.
How is the CP2E-N40DT1-D programmed?
Use CX-Programmer 9.0 or later, normally bundled with CX-One 4.x or later. The project uploads over either Ethernet port using FINS / TCP, or over USB on the lower-cost CP2E variants. Ladder, function block, and structured text are all supported on the same project - the CP2E does not require a separate IEC 61131-3 tool.
Can the CP2E-N40DT1-D connect to an NS-series HMI over Ethernet?
Yes - the NS5 / NS8 / NS10 / NS12 / NS15 HMIs support FINS / Ethernet, and the CP2E exposes its standard FINS port on either Ethernet socket. Use the HMI's Ethernet port for screen upload and runtime data, and the second CP2E Ethernet port for the plant network drop. No external switch is needed - the dual ports have a built-in switch.
