The 0TG Terminal Guards series is a family of USB-based hardware key modules used for B&R license management and protection of individual software components on the target system.
The series stores licenses on a removable Technology Guard dongle and supports secure handling with encryption methods including AES, SHA-256, RSA, and ECC, while Automation Runtime checks whether the required licenses are present. Within the range, the modules are available as MSD and HID variants, and one version also combines the licensing function with integrated flash memory for additional application or machine data storage. The series also includes features such as tamper-resistant operating-hours counters, support for multiple licenses on one device, user-specific data storage, and operation through the AsGuard library. Overall, the 0TG series is intended to provide portable license protection and optional data storage for B&R automation systems through compact USB-connected hardware keys.
