EPAS-3 (Electronic Programmable Automation System) is an IEC 61131-3 compliant programming environment. It integrates PLC functionality, motion control, and robotic path planning into a single software suite. Key Capabilities
You will likely need to register for a free standard business account to gain access to the download links.
Remember: Free software is not free if it costs you a $50,000 machine repair or a week of production loss. Always obtain industrial software through verified channels.
Once installed, establishing a connection to a PacDrive M controller requires correct network routing configurations. IP Address Configuration

Despite the download difficulties, EPAS-3 was a crucial tool in its time, specifically designed to work with ELAU's and PMC-2 product lines. It combined the configuration, programming, and diagnostic functions for these servo controllers and positioning drives.
Requires "Compatibility Mode" or deployment inside a 32-bit Windows 7 Virtual Machine (VM) such as VMware or VirtualBox.
: You can download ELAU PacDrive Diagnostics for free, which provides error analysis and service data for the PacDrive system without requiring the full EPAS-3 suite. Technical Details
EPAS3 was essentially the tool for working with the PMC-2, while later versions like EPAS-4 were designed for the PacDrive system. This distinction is critical: while EPAS-4 works with PacDrive controllers (C400, C600, etc.), EPAS3 is the specific software for the older PMC-2 hardware. These two versions are not interchangeable—attempting to use EPAS-4 to program a PMC-2 controller may not be effective, as confirmed by users who have tried. EPAS-3 (Electronic Programmable Automation System) is an IEC
Schneider Electric provides conversion utilities and engineering services capable of porting legacy EPAS-3 source code into the modern Machine Expert platform.
Uses IEC 61131-3 programming languages, allowing for industry-standard logic development.

If the 2-hour runtime limit is a dealbreaker, consider these legal alternatives (though they are not Elau): Remember: Free software is not free if it
Enter the exact IP address configured on your ELAU controller (verify this via the controller's integrated display panel if available).
The same caution applies to DLL files or other software components that appear to offer EPAS functionality—these could easily be security threats.
Windows XP (32-bit) and Windows 7 (32-bit) are the native operating systems for EPAS-3.
