ABB RLM01 一種冗余鏈接模塊
ABB RLM01是一種冗余鏈接模塊，用于將兩條冗余鏈路轉(zhuǎn)換為一條PROFIBUS DP鏈路，反之亦然。它能夠擴大信號形式和輸入數(shù)據(jù)的振幅，同時監(jiān)控3條鏈路的活動和錯誤狀態(tài)。RLM01具有3個PROFIBUS接口，支持的傳輸速率范圍為9.6 Kbps-12 Mbps，并可以連接多達31臺PROFIBUS客戶端。此外，如果通過前面板的LED或是信號接觸器來指示錯誤，可以從8個接頭的端子板讀取特定信息來進行診斷。
ABB RLM01模塊可以直接定位在主模塊旁邊，或者在幾個奴隸的公共汽車段前面，或者在單個奴隸面前。
ABB RLM01 適合各種工業(yè)現(xiàn)場環(huán)境，實現(xiàn)單總線和冗余雙總線的相互轉(zhuǎn)換，有廣泛的應用場景。
例如，可以將單電纜總線轉(zhuǎn)換為冗余的Profibus DP總線，也可以將冗余的Profibus DP總線轉(zhuǎn)換為單電纜總線。另外，它可以將不冗余的DP設(shè)備轉(zhuǎn)成冗余的DP接口，例如把AC800F的FI830F的單DP轉(zhuǎn)成雙DP。同時，它也可以將冗余的雙DP轉(zhuǎn)成單DP，例如把冗余的CI854A的2根DP轉(zhuǎn)成1個DP去連接變頻器的1個DP口。
RLM01也可以用非ABB系統(tǒng)中，例如AC800F的單DP去連接圖爾克的EXCOM(雙DP)，或者西門子400的單DP轉(zhuǎn)成雙DP，來連接ABB的S800(雙DP)。這些說明了RLM01具有廣泛的適用性。
ABB RLM01在應用場景中具有以下用途：
總之，ABB RLM01在應用場景中可以用于轉(zhuǎn)換DP設(shè)備類型、增加或減少設(shè)備的冗余性，以及兼容非ABB系統(tǒng)，成為不同設(shè)備之間進行轉(zhuǎn)換的關(guān)鍵模塊。
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.
