    Abstract: An industrial device is configured to implement a lightweight file authentication sequence that rapidly verifies the integrity of mobile code supplied to the industrial device. The industrial device generates a file authentication code (FAC), which is stored on the industrial device and only made accessible to users via a local connection to the industrial device. The device-specific file FAC is installed on the program development application used to develop or edit the mobile code to be executed on the industrial device. The development application provides the mobile code to the industrial device together with a hash-based message authentication code (HMAC) generated using a retrieved copy of the FAC. The industrial device only permits execution of the mobile code if the HMAC included with the mobile code matches a locally created HMAC generated by the industrial device based on the mobile code and the device's local copy of the FAC.

    Abstract: In some embodiments, a motor drive system includes a communication subassembly electrically coupled to a control subassembly for providing communication between the control subassembly and at least one external device. The control subassembly and the communication subassembly transmit and receive control data independently of messaging data, greatly enhancing performance and reducing the workload of processors on the control subassembly and communication subassembly. Additionally, the control subassembly and the communication subassembly transmit message data via sequence count based messaging. Communications between the communication subassembly and the control subassembly may include a series of timeout periods and retries, increasing reliability.

    Abstract translation: 在一些实施例中，电机驱动系统包括电连接到控制子组件的通信子组件，用于提供控制子组件与至少一个外部设备之间的通信。 控制子组件和通信子组件独立于消息传送数据发送和接收控制数据，大大提高了处理器在控制子组件和通信子组件上的性能并降低了其工作量。 此外，控制子组件和通信子组件通过基于序列计数的消息传送来发送消息数据。 通信子组件和控制子组件之间的通信可以包括一系列超时周期和重试次数，增加可靠性。
