The official version of Zelio Soft 2 v5.4.0 was released by Schneider Electric on April 6, 2021. While there is no official "portable" version (standalone .exe without installation) provided by the manufacturer, the software is free and can be managed through standard installation on Windows 10 systems. Download and Official Sources
For the most secure and up-to-date experience, you should use the official installer. Note that while v5.4.0 is widely used, a newer stable version, v5.4.2.2, is currently available.
Official v5.4.0 Download: Available on the Schneider Electric Global Download Center.
Latest v5.4.2.2 Download: Can be found on the Schneider Electric India support page.
Drivers: If you are using a programming cable (like the SR2USB01), you must also download and install the specific USB drivers separately for the hardware to be recognized. Software Overview & Features
Zelio Soft 2 is the primary configuration tool for Zelio Logic smart relays (SR2 and SR3 ranges), aimed at managing simple automation systems.
Programming Languages: Supports both Ladder Diagram (LD) and Function Block Diagram (FBD).
Multi-language Support: Available in English, French, German, Italian, Portuguese, and Spanish.
Simulation & Testing: Includes a simulation mode that allows users to test programs on a PC without needing the physical relay connected.
Communication: Manages program transfers (Upload/Download) between the PC and the module via serial or USB cables. How to Create a "Portable" Setup (Unofficial) zelio soft 2 v540 download portable
Since an official portable executable does not exist, users who need to run the software without a full installation process on multiple machines typically use one of two methods:
Virtual Machine (VM): Install Zelio Soft 2 on a lightweight Windows VM (using VirtualBox or VMware). You can move the entire VM file on a USB drive and run it on any computer with the VM player installed.
Installation Directory Copy: Some users attempt to copy the installed program folder (usually in C:\Program Files (x86)\Schneider Electric\Zelio Soft 2) to a USB drive. However, this often fails because the software requires registered DLLs and specific communication drivers (COM ports) to be installed in the host's Windows registry to function correctly with hardware. Standard Installation Steps
If you choose the official route, the process is straightforward: Launch Setup: Double-click the downloaded .exe file.
Configuration: Accept the license and choose the installation directory (default is recommended).
Driver Setup: During installation, ensure you allow any prompts for device drivers or communication protocols, as these are critical for PLC communication.
First Launch: Open the software and navigate to Transfer > Communication Configuration to select the correct COM port for your relay.
ZelioSoft2 (V5.4.0) programming software - Schneider Electric
Finding a truly "portable" version of Zelio Soft 2 v5.4.0 is difficult because Schneider Electric typically distributes the software as a full Windows installer. Official "portable" (no-install) versions are not standardly released by the manufacturer. The official version of Zelio Soft 2 v5
However, you can achieve a portable-like setup or find the official installer using the steps below. 1. Official Download (Recommended)
The safest and most stable way to get Zelio Soft 2 v5.4 is directly from Schneider Electric. Using an official installer ensures you have all the necessary USB drivers for the Zelio logic modules, which "portable" versions often lack.
Source: Visit the Schneider Electric Software & Firmware page. Version: Look for "Zelio Soft 2 v5.4.x".
Installation: Even though it's an installer, it is lightweight and runs well on most Windows versions (7, 10, and 11). 2. Creating a "DIY" Portable Version
If you need to run the software without a full installation on multiple machines, you can try this method: Install the software on a "master" PC.
Copy the installation folder (usually C:\Program Files (x86)\Schneider Electric\Zelio Soft 2) onto a USB drive.
Drivers: On any new PC, you will still likely need to install the USB communication drivers separately for the PC-to-PLC cable to work. The executable (ZelioSoft2.exe) may run, but it won't "talk" to the hardware without those drivers. 3. Caution on Third-Party "Portable" Links
You may find "Portable Zelio Soft" on file-sharing sites or forums. Exercise extreme caution:
Security Risks: These are often modified by third parties and can contain malware. Download the official installer as described above
Stability: PLC software requires specific registry entries and .NET framework versions to compile logic correctly. Portable rips often crash during the "Simulation" or "Transfer" phases. Key Features of v5.4 Compatibility: Improved support for Windows 10 and 11.
Programming: Supports both LADDER and FBD (Function Block Diagram) languages.
Simulation: Includes an offline simulator so you can test your logic without the physical hardware.
I understand you're looking for a portable version of Zelio Soft 2 v5.40 (likely for Schneider Electric's Zelio Logic programmable relays).
Here is an honest, practical review of what you can expect regarding a "portable" download for this specific version:
D:\PortableApps\ZelioSoft2_V540.ZelioSoft2.exe.C:\Windows\System32 (if missing) into the same folder:
msvcp71.dll, msvcr71.dll (Visual C++ runtimes).comdlg32.ocx (if using old VB6 components).regsvr32 /s comdlg32.ocx from the local folder using a batch script.Instead of hunting for a "portable" hack:
