Suco has transitioned newer devices (like e-timer) to CODESYS V3 or web-based IDEs. If you are programming a legacy S40 (K-timer), Sucosoft S40 is your only option. In rare cases, you may use CODESYS V2.3 with the Suco target file, but this is unsupported and lacks hardware-specific libraries.
If you work in industrial automation, wind energy, or mobile hydraulics, you have likely encountered the robust line of Suco controllers. At the heart of programming these devices lies Sucosoft S40—an IEC 61131-3 compliant programming environment based on CODESYS. This software allows engineers to program, debug, and deploy logic onto Suco ESX, ESX-M, and other 32-bit controller families.
However, finding a legitimate, safe download link for Sucosoft S40 and correctly installing it can be challenging. Unlike mainstream PLC software, Suco’s distribution often requires direct contact with distributors or specific portal access. This article will walk you through everything you need to know about the sucosoft s40 programming software install download process, including system requirements, installation steps, driver configuration, and common pitfalls.
The last stable release of Sucosoft S40 is V4.5.x. Do not confuse this with Sucosoft S50 (V5.x). Installing the wrong version will prevent detection of your ESX controllers.
Warning: Avoid random third-party websites offering “cracked” or “free” Sucosoft S40 downloads. These often contain malware or missing runtime components. Always verify file hashes with your supplier.
Follow these steps precisely. We assume you have obtained the legitimate Sucosoft_S40_V4.5.2.0_Setup.zip (or similar) from your distributor.
To avoid corrupting your installation:
Software installation is only half the battle; establishing communication with the PLC is the critical next step.

How to Download and Install SucoSoft S40 Programming Software
If you are working with legacy Moeller (now Eaton) PLC systems like the PS4-200, PS416, or PS4, you likely need the SucoSoft S40 programming software. While modern automation has moved toward CODESYS-based platforms like xSoft-CoDeSys, many industrial machines still rely on the stability of S40.
This guide provides a walkthrough on how to safely find, download, and install SucoSoft S40 to get your logic controller back online. 1. Where to Download SucoSoft S40
Because SucoSoft S40 is considered a legacy product, it is no longer the flagship software on the primary Eaton website. However, you can still acquire it through the following channels:
Eaton Download Center: Search the Eaton Software Download Portal for "SucoSoft" or "S40." You may need to look under the "Support" or "Documentation" sections. Suco has transitioned newer devices (like e-timer) to
Authorized Distributors: Many automation parts suppliers provide download links for legacy software to support the hardware they sell.
Original Installation Media: If your facility has the original CD-ROM, this is often the most reliable source, as it includes the necessary license keys and hardware drivers for serial communication.
Note: Always ensure you are downloading from a reputable source to avoid malware or corrupted installation files. 2. System Requirements & Compatibility
SucoSoft S40 was designed during the Windows 95/98 and XP era. To run it on modern hardware, keep these requirements in mind:
Operating System: Windows XP (32-bit) is the native environment.
Windows 10/11 Workaround: S40 generally does not run natively on 64-bit Windows 10 or 11. To use it today, you should use a Virtual Machine (VM) running Windows XP.
Communication Port: You will need a physical COM port or a high-quality USB-to-RS232 adapter (specifically one that supports the Moeller programming cables like the UM 1-1 or PRG 3-G). 3. Installation Steps
Once you have located the setup files (usually a zipped folder or an ISO image), follow these steps:
Run as Administrator: Right-click setup.exe and select "Run as Administrator."
Compatibility Mode: If installing on Windows 7, right-click the setup file, go to Properties > Compatibility, and set it to "Windows XP Service Pack 3."
License Key: During installation, you will be prompted for a license key. This is typically found on the original software jacket. The last stable release of Sucosoft S40 is V4
Select Components: Choose the libraries relevant to your specific PLC hardware (e.g., PS4-200 series).
Restart: Once the installation bar reaches 100%, restart your computer (or VM) to initialize the communication drivers. 4. Configuring Communication
After installation, the most common hurdle is establishing a link between your PC and the PLC.
S40 Settings: Open the software and go to the communication settings. Ensure the COM port matches the one assigned by your Windows Device Manager. Baud Rate: The default is usually 19,200 or 9,600 bps.
Cabling: Ensure you are using the correct Moeller-specific pinout; a standard null-modem cable may not work for all PS4 models. 5. Why Still Use SucoSoft S40? While it may seem outdated, SucoSoft S40 is essential for: Uploading code from older machines that lack documentation.
Troubleshooting existing logic without migrating to a new (and expensive) PLC platform.
Minor modifications to timing or sensor logic in established production lines. Summary Checklist Keyword: SucoSoft S40 programming software install download Key OS: Windows XP (Use a VM for Win 10/11) Hardware: Moeller PS4 Series Tool: RS232 Programming Cable
