OMRON CP1H-XA40DT-D-SC PLC CPU Unit

Explanation for suffix-SC: -SC stands for Special Customer, a custom-made version. Its hardware is identical to the standard model CP1H-XA40DT-D, only factory firmware/parameters are customized. Programmi, wiring and expansions are fully compatible for direct replacement. No official public datasheet is available for-SC variant. Prioritize CP1H-XA40DT-D for procurement and spare-part replacement.

Note chiave

-SC has no public documentation. Hardware is fully equivalent to CP1H-XA40DT-D. No wiring or program modification required for replacement. Verify whether custom special parameters need re-downloading.
Built-in analog channels are non-isolated. Signal isolators shall be added for heavy-noise operating conditions.
Sufficient power rating for DC24V power supply; supply voltage shall not drop below 21.6 V when multiple expansion units are installed.

The-SC custom variant uses exactly the same software as standard CP1H-XA40DT-D; no dedicated special software version exists.

Main Programming Software: Programmatore CX

Minimum version requirement: V6.1 or newer. Field-commonly used versions: V9.0 / V9.3 / V9.6 (bundled within CX-One suite).
Supported programming languages: Diagramma a scala, ST Structured Text, Function Blocks FB.

Complete tool suite including CX-Programmer, simulator, driver debugging and network configuration tools, for full-scale project development.

CX-One Lite Ver4 (Light-weight Edition)

Compact installation containing only tools for compact PLCs, for CP1E/CP1L/CP1H series only. CX-One and CX-One Lite cannot be installed on the same PC simultaneously.

❗Important: CX-Programmer3 (new-generation Omron software) does NOT support CP1H series. CP1H is legacy hardware; only CX-Programmer V9 releases are applicable. Do not install CX-Programmer3.

Metodi di connessione PC-PLC

On-board USB port (più comune): Standard USB A-to-B printer cable, direct PC connection, no option board required. PLC side uses USB-B connector.
Porta seriale: Requires option board `CP1W-CIF01(RS232)` / `CP1W-CIF11(RS485)` plus serial programming cable.
Ethernet: Install Ethernet option board `CP1W-CIF41` for program download & monitoring over Ethernet cable.

OS Compatibility

Recommended OS: Windows7 / Windows10. Windows11 supports V9.6; compatibility mode may be required on some PCs.

Engineering Tips

Quando si crea un nuovo progetto, select CPU model CP1H-XA40DT-D directly. Do not select-SC. No-SC model entry exists in software because hardware is identical.
Program upload/download, monitoraggio, analog configuration and 4-axis pulse motion work exactly the same as standard CP1H-XA40DT-D.
Downloading user programs will not overwrite the-SC custom factory firmware; only user application program is modified.
