本篇文档《西门子_Sending Syslog Messages with a S7 CPU.pdf》主要介绍了如何在西门子S7系列PLC（可编程逻辑控制器）上实现SYSLOG功能，以便发送日志消息。SYSLOG是一种标准的网络事件报告协议，常用于监控和管理系统中的关键信息。在工业自动化环境中，S7 CPU通过集成的库或模块来支持SYSLOG通信，这有助于故障诊断、设备状态跟踪以及与企业网络和互联网的集成。 文档首先强调了该内容是西门子Applikations&Tools的一部分，旨在提供针对特定应用领域的解答，适用于 Siemens Industry Online Support。文章详细描述了如何配置和设置S7 CPU以实现SYSLOG功能，包括可能涉及的软件库描述（Library description更新至2011年6月），并指出所有信息受版权保护。 文中提醒读者，尽管这些功能专注于自动化任务的实现，但在实际操作时必须考虑工业安全。连接设备到其他系统组件，如工厂网络或互联网时，需要采取相应的防护措施，以防止潜在的安全威胁。相关的信息可以在Item-ID 50203404的文档中找到，那里提供了更多关于工业安全的指导。 此外，文档还推荐用户利用西门子在线技术支持平台——Technical Forum，通过讨论区主动参与问题交流，提出疑问、分享建议和解决技术难题。在这个平台上，工程师和技术专家可以共同探讨和解决问题，确保在实际应用中能够充分利用SYSLOG功能，提升整体系统的可靠性和效率。 这篇文档是西门子用户在使用S7 CPU进行SYSLOG消息发送时的重要参考资料，涵盖了技术细节、安全注意事项以及寻求技术支持的途径。通过理解和遵循其中的指南，用户能够更好地管理他们的自动化系统，并确保与企业网络的无缝集成。

The 18th China Jiliang University Programming Contest is approaching, Little Gyro wants to send plenty of messages by e-mail to invite people participating in the competition. However, Little Gyro only has one e-mail account (acm309@126.com) to send these messages. In order to invite more candidates as possible, Little Gyro needs your help. Given the whole time table of the e-mail messages Little Gyro wants to send, including the start time and the end time of each message, and it usually doesn’t take the same time when Little Gyro sending different e-mail messages. Besides, Little Gyro cannot send two or more messages at the same time. That means Little Gyro can send the next message only if the start time after the end time of the previous one. Now Little Gyro wants to know how many e-mail messages he can send to the competition candidates at most.

Then, we can start sending messages from the earliest end time to the latest end time, and choose the message with the earliest start time that doesn't conflict with the previously sent messages....

Connect to the USB stack (usbd_connect()) and provide two callbacks: one for insertion and one for removal. In the insertion callback: Connect to the USB device (usbd_attach()). Get descriptors (usbd_descriptor()). Select the configuration (usbd_select_config()) and interface (usbd_select_interface()). Set up communications pipes to the appropriate endpoint (usbd_open_pipe()). In the removal callback, detach from the USB device (usbd_detach()). Set up all data communications (e.g. reading and writing data, sending and receiving control information, etc.) via the usbd_setup_*() functions (usbd_setup_bulk(), usbd_setup_interrupt(), etc.). Initiate data transfer using the usbd_io() function (with completion callbacks if required). 这是官方的示例流程
