Features: Plug and play, no additional configuration required, communication status monitored through LED (Swg Bus Rx/Tx).
2. Switchgear Control Network
Architecture: Based on standard Ethernet (LAN2), supporting direct connection (cross cable) or connecting multiple MLinks, MView (human-machine interface), and engineering tools (MNavigate) through switches.
Security requirements: If you need to access the factory network, you need to configure a firewall and router to prevent unauthorized access.
Time synchronization scheme:
Option 1: Third party NTP servers (such as switches with GPS) provide time signals.
Option 2: MLink acts as an NTP server to synchronize time with other devices (with a built-in RTC that can cache for 3 hours).
Operation and maintenance
1. Initial setup
Tool: Use MNavigate software to configure parameters such as IP address, subnet mask, time server, etc. The parameters need to be written to the CF card and restarted to take effect.
Default value:
LAN2 IP：192.168.200.100，LAN1 IP：192.168.100.100
DHCP is not supported, network parameters need to be manually configured.
2. Installation steps
Physical installation: Installed in the control cable compartment of the MNS iS cabinet, fixed with metal brackets and supporting quick insertion and removal.
CF card operation: When inserting, pay attention to the direction (mechanical coding to prevent reverse insertion), and the configuration file needs to be written through MNavigate.
3. Fault diagnosis
LED indicator light: It displays the operating status, communication faults, and redundancy status through 8 LEDs (such as LED2 indicating system faults and LED6 indicating DCS communication activation).
Common problem handling:
Network failure: Check IP configuration, ping test connectivity, and rewrite CF card configuration.
MControl offline: Confirm internal bus connection and MControl online status settings.
Documentation and Compatibility

System compatibility: Only applicable to MNS iS System Release 7.0, please refer to the latest system guidelines for functional implementation.
Summarize
The MLink module is the communication hub of ABB MNS iS system, which seamlessly integrates motor control with upper level systems in industrial environments through flexible protocol support and reliable hardware design. Its core advantages include multi protocol compatibility, high time synchronization accuracy, and strong redundancy reliability, making it suitable for automation control systems that require high real-time performance and stability. Operation and maintenance rely on the specialized tool MNavigate, and attention should be paid to network configuration specifications and hardware installation details.
