ABB MNS iS System MLink 1TGE120021 Interface Module

This document is the user manual (system version V7.0) for the MLink interface module (model 1TGE120021) in the ABB MNS iS system. It mainly introduces its hardware features, software modules, communication interfaces, and operation and maintenance. The following is a detailed summary:

Product positioning and target users

Positioning: MLink is an industrial PC module that serves as the core communication interface for MNS iS systems, connecting internal motor control units (MControl) and external control systems (such as DCS, PLC), supporting data exchange, status monitoring, and system integration.

Target users: System engineers, control engineers, familiar with fieldbus (such as PROFIBUS, Modbus) and industrial communication basics.

hardware features

1. Model and Communication Protocol

Supported protocols: PROFIBUS DP/DP-V1, Modbus RTU/TCP, PROFINET IO (only compatible with ABB 800xA system).

Hardware model:

PROFIBUS DP：1TGE120021R0110

Modbus：1TGE120021R0010

Key parameters:

Power supply: 24V DC (19-31V DC), typical power consumption 800mA

Size: 140 × 160 × 165mm, weight 2.5kg

Working temperature: 0 ° C~55 ° C, protection level IP51

Mean Time Between Failures (MTBF): 46 years (40 ° C environment)

2. Interface and Connection

Front board interface:

Internal communication: Blue Sub-D 9-pin interface (Switchgear Bus), connected to MControl, supports redundant configuration.

External communication:

PROFIBUS DP: Black interface with communication status LED (yellow running, green ready).

Modbus RTU: RS485 interface (Serial 2).

Ethernet (LAN1/LAN2): LAN1 is used for Modbus TCP or PROFINET, while LAN2 connects to the control network (10/100 Base-T).

Other interfaces: reset button, CF card slot (supporting hot swappable protection), power terminal (+24V/GND).

Software modules and functions

Core module:

Web Server: Access the MView interface through a browser to monitor system status (activation required).

OPC Server: Supports data acquisition (DA) and alarm events (AE), requiring separate software installation.

Fieldbus module: Implement protocol conversion with DCS, depending on hardware model (such as PROFIBUS/Modbus).

Time synchronization: Supports NTP protocol and can provide timestamps through GPS or internal RTC to ensure event recording accuracy.

Redundancy support: Dual MLink modules are synchronized through redundant cables, with primary and backup switching to ensure system reliability.

Communication network configuration

1. Internal network (Switchgear Bus)

Function: Connect MLink and MControl (up to 60), the cable shielding layer needs to be grounded at both ends, and supports bus topology and terminal resistance configuration.

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.
