Where to get files (recommended sources)

  • Schneider Electric official website — product support / downloads for Zelio Logic.
  • FTDI Drivers (if the module uses FTDI chip): https://ftdichip.com/drivers/ (download the VCP driver matching Windows 10 x86/x64).
  • Avoid unofficial driver-hosting sites to reduce malware risk.

5. Known Issues in 2021

  • Code 10 / Code 52 – Driver signature or legacy chip error.
  • Cable not recognized after Windows 10 update (e.g., 2004, 20H2).
  • Incompatibility with genuine Prolific v3.8+ drivers – Schneider’s driver had to be forced.
  • 64-bit Windows 10 – required workaround (disable signature enforcement) for many users.
