VersaPro 2.04 (often called Version 204) was the last stable build before GE Fanuc transitioned to Proficy Machine Edition. While Proficy is powerful, many legacy plants still run on older PLCs (Series 90-30, 90-70, and Micro) that were programmed natively in VersaPro.
Before we dive into the download process, let's take a brief look at what VersaPro 204 software is and its significance. VersaPro 204 is a programming software used for industrial automation and control systems.
