ABB RLM01

ABB RLM01 is a redundant link module designed for PROFIBUS DP and FMS fieldbus.The following is a detailed introduction to the module:

1.Product Overview

Product Name:ABB PROFIBUS Redundant Link Module RLM01

Brand:ABB

Function:Improve the reliability of the PROFIBUS network,prevent single point failures,and ensure the continuous operation of the system

ABB RLM01

2.Main Functions and Features

Redundant Design:

The RLM01 module supports two independent communication lines.When the main line fails,it automatically switches to the backup line to ensure uninterrupted communication.

The module can flexibly convert a non-redundant PROFIBUS link into two redundant links,or integrate two redundant links into one PROFIBUS DP link.

Fault Detection and Switching:

Real-time monitoring of the status of the two links,once a fault is detected,automatically switch to the backup link.

Provide hot backup function.The backup line is in standby state under normal circumstances.Once a fault occurs,it can immediately take over the communication task and achieve seamless switching.

Data Forwarding and Integrity:

Forward the data from the main link to the backup link to ensure the integrity and real-time nature of the data.

Signal enhancement and monitoring:

Enlarge the signal form and amplitude of input data to ensure the quality of the signal during transmission.

Monitor the activity and error status of three links(including the main link,backup link and possible third link).

ABB RLM01

Easy to configure and manage:

Through ABB’s dedicated configuration software,users can easily configure and manage the RLM01 module.

Realize the monitoring,diagnosis and alarm functions of the communication line.

Wide compatibility:

Supports a variety of transmission rates,from 9.6Kbps to 12Mbps,and can be seamlessly connected to various PROFIBUS devices.

The transparent PROFIBUS configuration design eliminates the need for additional slave address settings,simplifying the configuration process.
