Step 2: Use the Schneider Electric Software Installer (SESI)
As of 2024/2025, Schneider Electric has ended mainstream support for SoMachine V4.3. It is no longer receiving security patches or functional updates. You should only use this version for maintaining existing machines, not for new greenfield projects.
: It programs Modicon M238, M241, M251, and M258 logic controllers, as well as LMC058/078 motion controllers and Magelis HMIs.
Schneider Electric’s SoMachine V4.3 is a legacy flagship software environment designed for developing, configuring, and commissioning entire automation systems. Built on the robust CODESYS platform, this single software environment handles logic control, motion control, HMI configuration, and network automation. --- Schneider Somachine V4.3 Download -

Preferred for process control loops and interlocking logic due to its clear visual representation of data flow. : It programs Modicon M238, M241, M251, and
The software typically includes a 21-day trial license , making it highly useful for emergency troubleshooting or evaluating compatibility before committing to a permanent team or single-station license.
SoMachine V4.3 projects use the .project or archived .projectarchive format, which can be cleanly imported into EcoStruxure Machine Expert V1.1 or higher. The modernization wizard automatically converts older device descriptors to their newer counterparts, though manual validation of pointer addresses and industrial network configurations is highly recommended after conversion.
Before attempting to install SoMachine V4.3, ensuring your engineering workstation meets the baseline operating system and hardware criteria is vital.
Newer versions include an automated project converter that safely updates older .project files created in SoMachine V4.3.
: Includes tested, validated, and documented (TVDA) project templates and application libraries.
