ABB RLM01 一种冗余链接模块

ABB RLM01是一种冗余链接模块，用于将两条冗余链路转换为一条PROFIBUS DP链路，反之亦然。它能够扩大信号形式和输入数据的振幅，同时监控3条链路的活动和错误状态。RLM01具有3个PROFIBUS接口，支持的传输速率范围为9.6 Kbps-12 Mbps，并可以连接多达31台PROFIBUS客户端。此外，如果通过前面板的LED或是信号接触器来指示错误，可以从8个接头的端子板读取特定信息来进行诊断。

ABB RLM01模块可以直接定位在主模块旁边，或者在几个奴隶的公共汽车段前面，或者在单个奴隶面前。

ABB RLM01 适合各种工业现场环境，实现单总线和冗余双总线的相互转换，有广泛的应用场景。

例如，可以将单电缆总线转换为冗余的Profibus DP总线，也可以将冗余的Profibus DP总线转换为单电缆总线。另外，它可以将不冗余的DP设备转成冗余的DP接口，例如把AC800F的FI830F的单DP转成双DP。同时，它也可以将冗余的双DP转成单DP，例如把冗余的CI854A的2根DP转成1个DP去连接变频器的1个DP口。

RLM01也可以用非ABB系统中，例如AC800F的单DP去连接图尔克的EXCOM(双DP)，或者西门子400的单DP转成双DP，来连接ABB的S800(双DP)。这些说明了RLM01具有广泛的适用性。

ABB RLM01在应用场景中具有以下用途：

1. 转换DP设备类型：RLM01可以将单电缆总线转换为冗余的Profibus DP总线，也可以将冗余的Profibus DP总线转换为单电缆总线。这使得RLM01成为不同DP设备之间进行转换的关键模块。
2. 增加设备冗余性：RLM01可以将不冗余的DP设备转成冗余的DP接口，从而提高设备的可靠性和稳定性。例如，它可以将在AC800F的FI830F的单DP转成双DP，增加了设备的冗余性。
3. 减少设备冗余性：另一方面，RLM01也可以将冗余的双DP转成单DP，例如把冗余的CI854A的2根DP转成1个DP去连接变频器的1个DP口。这可以简化设备连接，减少冗余的线路和设备。
4. 兼容非ABB系统：RLM01不仅适用于ABB系统，也可以用于非ABB系统。例如，它可以用于AC800F的单DP去连接图尔克的EXCOM(双DP)，或者西门子400的单DP转成双DP，来连接ABB的S800(双DP)。这意味着RLM01可以作为不同系统之间进行连接的关键设备。

总之，ABB RLM01在应用场景中可以用于转换DP设备类型、增加或减少设备的冗余性，以及兼容非ABB系统，成为不同设备之间进行转换的关键模块。

ABB RLM01 is a redundant link module used to convert two redundant links into one PROFIBUS DP link, and vice versa. It can expand the signal form and amplitude of input data, while monitoring the activity and error status of three links. RLM01 has three PROFIBUS interfaces, supports a transmission rate range of 9.6 Kbps to 12 Mbps, and can connect up to 31 PROFIBUS clients. In addition, if an error is indicated through the LED or signal contactor on the front panel, specific information can be read from the terminal blocks of the 8 connectors for diagnosis.

The ABB RLM01 module can be directly located next to the main module, in front of several slave bus sections, or in front of a single slave.

ABB RLM01 is suitable for various industrial field environments, achieving mutual conversion between single bus and redundant dual bus, and has a wide range of application scenarios.

For example, a single cable bus can be converted to a redundant Profibus DP bus, or a redundant Profibus DP bus can be converted to a single cable bus. In addition, it can convert non redundant DP devices into redundant DP interfaces, such as converting single DP of AC800F's FI830F to dual DP. At the same time, it can also convert redundant dual DPs into single DPs, such as converting the two DPs of redundant CI854A into one DP to connect to one DP port of the frequency converter.

RLM01 can also be used in non ABB systems, such as AC800F's single DP to connect to Turk's EXCOM (dual DP), or Siemens 400's single DP to double DP to connect to ABB's S800 (dual DP). These demonstrate the widespread applicability of RLM01.

ABB RLM01 has the following uses in application scenarios:

Convert DP device type: RLM01 can convert a single cable bus to a redundant Profibus DP bus, and can also convert a redundant Profibus DP bus to a single cable bus. This makes RLM01 a key module for converting between different DP devices.

Increase device redundancy: RLM01 can convert non redundant DP devices into redundant DP interfaces, thereby improving device reliability and stability. For example, it can convert the single DP of FI830F in AC800F to dual DP, increasing the redundancy of the equipment.

Reduce device redundancy: On the other hand, RLM01 can also convert redundant dual DPs into single DPs, such as converting two DPs of redundant CI854A into one DP to connect to one DP port of the frequency converter. This can simplify device connections and reduce redundant lines and devices.

Compatible with non ABB systems: RLM01 is not only suitable for ABB systems, but can also be used for non ABB systems. For example, it can be used for AC800F single DP connection to Turk's EXCOM (dual DP), or Siemens 400 single DP conversion to dual DP connection to ABB's S800 (dual DP). This means that RLM01 can serve as a key device for connecting different systems.

In summary, ABB RLM01 can be used in application scenarios to convert DP device types, increase or reduce device redundancy, and is compatible with non ABB systems, becoming a key module for conversion between different devices.
