Product Description:

The C9900-H391 belongs to the Beckhoff C9 PC Accessories series and is supplied by Beckhoff as a bootable service medium for its industrial automation computers. The device operates as a self-contained USB flash module that loads diagnostic and imaging tools so users can back up or restore operating systems without removing drives from the machine. By starting the target PC from this stick, the system opens a clean environment that bypasses the installed operating system and allows image cloning or recovery.

The stick provides a storage capacity of 32 GB implemented with SLC NAND, giving higher write endurance than multi-level cell designs. Data exchange occurs over a USB 3.0 interface, yet the medium also works on controllers that only expose the USB 2.0 signaling rate. To execute the included software stack, the host needs at least 2 GB of RAM, after which the predefined RAM Boot procedure copies the Windows PE image into volatile memory and runs entirely from there. The internal build references BST version 2.1.x.xx, and the flash is preloaded with Acronis Backup utilities alongside Beckhoff scripts that automate image capture and deployment.

All recovery routines are driven by Acronis Backup release 11.x, so the interface remains uniform across machines. The boot environment supports both UEFI and Legacy BIOS types, allowing the same stick to initialize current CX series controllers and earlier IPC models. The operating environment is based on Windows PE, and the finished images target standard Windows installations that run production HMI or PLC software. The hardware works with any Beckhoff Industrial or Embedded PC that meets the minimum USB and memory requirements, providing a single portable tool for scheduled cloning, emergency restoration, or system deployment.
