Comparison Between Old & 代替モデル (Official Discontinuation Notice)

Original model CP1E-N40DT-D is gradually discontinued; 代替モデル: CP1E-N40SDT-D

アイテム	CP1E-N40DT-D (Old Version)	CP1E-N40SDT-D (New Replacement Model)
コミュニケーションの拡大	サポート 1 CIF option board	No expansion slot; only built-in USB + RS232
Analog Potentiometers	2 adjustable potentiometers onboard	Eliminated
Unit Depth	85mm	79mm (slimmer design)
I/O, パルス出力, カウンタ, プログラム容量	Fully identical	Fully identical

選択の推奨事項:

Retain stock of old model if Ethernet / RS485 expansion options are required.

If only HMI connection and PC programming are needed, directly replace with N40SDT-D. Programs are fully compatible; only communication expansion functions are unavailable.

典型的なアプリケーションシナリオ
Standalone Machine Automation: 包装機, コンベアライン, small assembly equipment, injection molding auxiliary machines
Multi-axis Positioning: Simple multi-axis cutting, drilling and transfer mechanisms with stepper / servo drives (4-axis pulse output)
Single-station Production Line Control: Assembly line workstations, test fixtures, small warehouse sorting systems
Environmental Protection Equipment: Small-scale water treatment, logic control of fans and valves for waste gas purification
List of Commonly Used Matching Expansion Modules

Digital Modules: CP1W-8ER / 16ER (リレー出力), CP1W-8ET (Sinking Transistor Output)

アナログモジュール: CP1W-MAD44 (4AI + 2へ), CP1W-MAD11 (4 アナログ入力)

Communication Option Boards (Only compatible with old N40DT-D): CP1W-CIF41 (イーサネット), CIF11 (RS485 Modbus)

Critical Wiring Rules & Operation Prohibitions
Sinking Output Wiring: Connect positive pole of load to DC24V, negative pole to PLC output terminal, COM terminal to 0V. Reverse wiring is strictly forbidden and will burn output points.
Servo Drive via Pulse Output: Pulse signal cables must be twisted-shielded and routed away from power cables to reduce interference and pulse loss.
Do not share the same switching power supply for PLC main unit DC24V and external sensors, which may cause drift of input signals.
プログラムのバックアップ: Built-in lithium battery retains DM data and user programs. Service life approx. 5 年; replace with CP1W-BAT01 upon expiry.
Troubleshooting Matrix for Common Faults

故障の症状	根本的な原因	解決
No pulse output action	Reversed output wiring, COM terminal not connected to 0V, pulse instructions not enabled in program	Verify sinking wiring; check parameters of PULS / SPED instructions
Input points permanently ON / No signal input	Missing external 24V power supply, mismatched NPN/PNP sensor type	NPN sensors match sinking input of this PLC; replace sensor or install signal conversion module
PLC Link communication failure	RS485 terminal resistor not activated, duplicated station numbers, reversed A/B wiring	Enable terminal resistors on both ends, standardize A/B cable sequence, modify duplicated station numbers
Red ERR light flashes after power-on	Program error, short-circuit on expansion module, low battery voltage	Clear program for testing; disconnect expansion modules one by one for inspection; replace lithium battery

Full Specification of Programming Software for OMRON CP1E-N40DT-D

Core Programming Software: CX-Programmer (Abbreviated as CX-P)

It is the only official programming tool dedicated to all OMRON PLC series (CP1E/CP2E/CJ/CS etc.), fully compatible with CP1E-N40DT-D.

Minimum Version Requirements

基本機能 (pulse control, RS485通信): CX-Programmer V9.03 or higher
When using CP1W-CIF41 Ethernet option board: Must install V9.12 or higher

CX-Programmer (PLC programming)

CX-Simulator (Offline PLC simulation; supports CP1E program emulation)

CX-Designer (HMI programming)

CX-Motion, CX-Protocol, communication drivers and other servo / HMI configuration tools

Suitable for projects requiring simultaneous debugging of PLC, HMI and servo drives.

2.2 CX-One Lite (Compact Version for Micro PLCs Only)

Only contains Micro PLC edition of CX-Programmer, without HMI and servo software. Smaller installation size, exclusively for compact CP1E/CP2E PLCs, ideal for standalone projects requiring only PLC programming.

Supported Programming Languages (All compatible with CP1E-N40DT-D)
ラダー図 (LD) – Most widely used
機能ブロック図 (FBD)
Structured Text (ST) – C-like high-level language
逐次関数チャート (SFC) – Step-based process flow

Pre-built function blocks for pulse positioning, high-speed counter and Modbus-RTU are embedded in the software, matching the 4-axis pulse output capability of this PLC.

PC-PLC Connection Methods (Communication Settings in Software)
Direct USB Connection (Most Convenient)

Mini-USB port on PLC main unit, standard printer USB cable. 選択 “USB” as communication type in software; driver-free recognition.

RS232 Serial Port: Onboard DB9 port for connection with HMI or PC serial port
RS485通信: Install CP1W-CIF11 option board
Ethernet Communication: Install CP1W-CIF41 Ethernet option board for remote program upload/download
Auxiliary Supporting Tools
CX-Simulator: Offline simulation without physical PLC; supports logic debugging, pulse positioning and I/O simulation. Only available in full CX-One package.
CX-Protocol: Debug custom communication messages between host computer and PLC
SLM License Manager: Software activation and authorization tool
一般的な注意事項
CX-One and CX-One Lite cannot be installed simultaneously; only one suite can be selected.
This software is commercial licensed. Official trial versions with time limits are available; official license purchase is required for long-term use.
Old CX-P versions V7 / V8 cannot recognize CP1E-N40DT-D and will trigger model mismatch errors.
When creating a new project, select device type: CP1E → N40DT-D to fully activate 4-axis pulse control, expansion module and communication option board functions.
