MOTOROLA MVME300 为在设备或插头中可选地激活

MOTOROLA MVME300:如果使用RS485传输技术，所有PROFIBUS现场设备通常连接成一个线路结构，在一个段中最多有32个节点(主节点和从节点)。每段的起点和终点都配有主动总线终端，必须连续供电。总线终端通常被实现为在设备或插头中可选地激活。如果有超过32个节点或网络跨度正在扩大，中继器必须用于连接网络。

MOTOROLA MVME300:如果使用MBP传输技术，基本上任何拓扑都是允许的。因此，线性和树形结构以及两者的组合都是可能的。在实践中，“主干和支线拓扑”已经成为事实上的标准，因为它特别清晰和布局合理。由于市场上技术成熟的安装技术，它还表现出高度的鲁棒性。一段的总长度不得超过1900米。此外，本质安全应用中支线的最大长度为60米

耦合MOTOROLA MVME300和MBP传输技术:MBP传输技术通常限于系统的某些子部分，例如危险区域中的一组现场设备。这些子段与RS485段的连接是使用段耦合器或链路实现的。

MOTOROLA MVME300: If RS485 transmission technology is used, all PROFIBUS field devices are typically connected in a line structure with up to 32 nodes (master and slave) in a segment. The start and end of each segment are equipped with active bus terminals, which must be continuously powered. Bus terminals are usually implemented to be optionally activated in the device or plug. If there are more than 32 nodes or the network span is expanding, Repeaters must be used to connect the network.

MOTOROLA MVME300: If you use MBP transport technology, basically any topology is allowed. Therefore, linear and tree structures and combinations of both are possible. In practice, the "trunk and feeder topology" has become the de facto standard because it is particularly clear and well laid out. It also shows a high degree of robustness due to the technically mature installation technology on the market. The total length of a section shall not exceed 1900 meters. In addition, the maximum length of the spur line in intrinsically safe applications is 60 meters

Coupling MOTOROLA MVME300 and MBP transmission technology :MBP transmission technology is typically limited to certain subparts of a system, such as a set of field devices in a hazardous area. The connection of these subsegments to the RS485 segment is achieved using a segment coupler or link.
