**课程名称：** RS485一切你需要知道的 **课程概述：** 本课程深入浅出地介绍了RS485通信的理论与实践知识，使其成为植物自动化领域事实上的数据通信标准。RS485在具有显著电干扰（噪声）和需要长距离传输的应用中表现出色，因此广泛应用于工业领域。它是一种经济高效的局域网（LAN）连接方式，允许在多点配置中连接多个接收器。需要注意的是，RS485本身并不包含通信协议。 通过本课程的学习，您将能够构建、维护和排除植物自动化领域中任何基于RS485网络的故障。课程包含一个PLC与计算机之间通过USB转RS485转换器进行的实际连接演示，这个例子对于有效排除RS485系统故障至关重要。完成本课程后，您将能够将来自相同或不同制造商的RS485兼容设备集成起来，形成一个完整、无缝的网络。
RS-485 is the de facto workhorse of data communications in the field of plant automation. It is very effective in applications with significant electrical interference (noise) requiring a long transmission distance. Thus, the standard is often used in industrial applications. It is as an inexpensive local area network (LAN) connection that allows multiple receivers to connect within a multi drop configuration. RS-485 does not include a communications protocol.This course delivers the theoretical and practical aspects of RS-485 in a very effective way, so that at the end, you will be able to build, maintain and troubleshoot any RS-485 based network in the plan automation field. The course features a live physical connection between a PLC and a Computer via a USB-to-RS485 converter, an example that is key to effective troubleshooting of RS-485 systems. After completing this course, you will be able to integrate devices from the same manufacturers and different manufacturers, that are RS-485 compliant, to form a complete seamless network.
