3. Comparison Between Old & Ersatzmodelle (Official Discontinuation Notice)

Original model CP1E-N40DT-D is gradually discontinued; Ersatzmodell: CP1E-N40SDT-D

Auswahlempfehlung:

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.

4. Typische Anwendungsszenarien
5. Standalone Machine Automation: Verpackungsmaschinen, conveyor lines, small assembly equipment, injection molding auxiliary machines
6. Multi-axis Positioning: Simple multi-axis cutting, drilling and transfer mechanisms with stepper / Servoantriebe (4-Achsenimpulsausgang)
7. Single-station Production Line Control: Assembly line workstations, test fixtures, small warehouse sorting systems
8. Environmental Protection Equipment: Small-scale water treatment, logic control of fans and valves for waste gas purification
9. List of Commonly Used Matching Expansion Modules

Digital Modules: CP1W-8ER / 16ER (Relaisausgang), CP1W-8ET (Sinking Transistor Output)

Analoge Module: CP1W-MAD44 (4KI + 2ZUM), CP1W-MAD11 (4 Analoge Eingänge)

Temperature Acquisition Modules: CP1W-TS002 / TS004 (Thermoelement), CP1W-PT100

Communication Option Boards (Only compatible with old N40DT-D): CP1W-CIF41 (Ethernet), CIF11 (RS485 Modbus)

6. Critical Wiring Rules & Operation Prohibitions
7. 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.
8. Servo Drive via Pulse Output: Pulse signal cables must be twisted-shielded and routed away from power cables to reduce interference and pulse loss.
9. Do not share the same switching power supply for PLC main unit DC24V and external sensors, which may cause drift of input signals.
10. Programmsicherung: Built-in lithium battery retains DM data and user programs. Service life approx. 5 Jahre; replace with CP1W-BAT01 upon expiry.

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

1. 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

1. Grundfunktionen (pulse control, RS485-Kommunikation): CX-Programmer V9.03 or higher
2. When using CP1W-CIF41 Ethernet option board: Must install V9.12 or higher
3. New main units / updated N40SDT-D model: Recommended version V9.6 / V9.73 (included in CX-One V4 series)
4. Two Installation Suites (CX-Programmer cannot be downloaded independently)

2.1 CX-One (Full Version, Empfohlen)

Integrated OMRON automation toolset including all industrial control software:

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.

3. Supported Programming Languages (All compatible with CP1E-N40DT-D)
4. Leiterdiagramm (LD) – Most widely used
5. Funktionsblockdiagramm (FBD)
6. Strukturierter Text (ST) – C-like high-level language
7. Sequential Function Chart (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.

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

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

2. RS232 Serial Port: Onboard DB9 port for connection with HMI or PC serial port
3. RS485 Communication: Install CP1W-CIF11 option board
4. Ethernet Communication: Install CP1W-CIF41 Ethernet option board for remote program upload/download
5. Auxiliary Supporting Tools
6. CX-Simulator: Offline simulation without physical PLC; supports logic debugging, pulse positioning and I/O simulation. Only available in full CX-One package.
7. CX-Protocol: Debug custom communication messages between host computer and PLC
8. SLM License Manager: Software activation and authorization tool
9. Allgemeine Hinweise
10. CX-One and CX-One Lite cannot be installed simultaneously; only one suite can be selected.
11. This software is commercial licensed. Official trial versions with time limits are available; official license purchase is required for long-term use.
12. Old CX-P versions V7 / V8 cannot recognize CP1E-N40DT-D and will trigger model mismatch errors.
13. 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.
