C9900-H356 BECKHOFF 4 GB Industrial USB 3.0 Media

Product Overview

The C9900-H356 (C9900-H356) is an industrial-grade USB flash drive engineered for high-reliability data storage and system recovery within Beckhoff Industrial PC (IPC) environments. Optimized for the rigorous demands of the factory floor, this 4 GB USB 3.0 stick is specifically designed to function as a boot medium, backup target, or software installation tool. In sectors such as CNC machining, automated warehousing, and semiconductor fabrication, the C9900-H356 provides a stable and ruggedized alternative to consumer-grade storage. Its industrial SLC (Single-Level Cell) or high-end flash architecture ensures long-term data retention and high write-cycle endurance, even in environments subject to extreme temperatures and mechanical vibration.

Technical Configuration

The C9900-H356 hardware utilizes the USB 3.0 SuperSpeed interface, providing significantly faster read and write performance compared to legacy USB 2.0 devices, which is critical when deploying large TwinCAT configurations or OS images. While consumer sticks often fail due to internal bit-rot or controller instability, this Beckhoff industrial media is validated for compatibility with the BIOS and UEFI firmware of the CX and C-series Industrial PCs. The 4 GB capacity is specifically sized to accommodate Windows Embedded Standard, TwinCAT runtime environments, and critical system backups, ensuring that the drive remains a lean, dedicated tool for engineering and maintenance personnel.

Technical Specifications

Technical FAQs

Is the C9900-H356 backwards compatible with USB 2.0 ports?

Yes, the C9900-H356 is fully backwards compatible with USB 2.0 interfaces found on older Beckhoff IPC models. However, the data transfer speed will be limited to the maximum throughput of the USB 2.0 bus (480 Mbps).

Can this USB stick be used as a permanent boot drive for Windows?

While the C9900-H356 is highly durable and capable of booting an OS, it is primarily intended for service tasks, software updates, and backup/restore operations. For permanent OS storage, Beckhoff recommends internal CFast, CF, or SSD media.

Does this drive require specific drivers for recognition in TwinCAT?

No, the drive is recognized as a standard mass storage device by the underlying operating system (Windows 10 IoT, WES7, etc.). It can be accessed directly for logging data or loading PLC projects without additional driver installation.

Engineering & Installation Guide

Backup and Recovery Best Practices:

When using the C9900-H356 for system recovery, it is recommended to use the Beckhoff Service Tool (BST). Ensure the IPC BIOS is configured to prioritize "Removable Devices" in the boot order. To maintain data integrity, always perform a "Safe Removal" in Windows before physically unplugging the stick, especially after writing large log files or project archives.

Handling in Industrial Environments:

Although the C9900-H356 is built for industrial use, keep the USB contacts free from conductive dust, oil, and metallic shavings common in machining environments. Use the protective cap when the drive is not in use. If the stick is used in a high-vibration environment (e.g., mounted on a moving machine arm), ensure it is plugged into a USB port with adequate mechanical clearance to prevent leverage damage to the IPC's internal USB header.

Format and File System:

For maximum compatibility across Beckhoff tools and different operating systems, the drive should ideally be formatted in FAT32 or NTFS, depending on the file size requirements. For bootable service tools, the FAT32 format is generally required by the IPC's UEFI/BIOS for proper recognition during the pre-boot phase.
