Description

The ABB 1TGE120021R0010 is an MLink Communication Gateway designed for the MNS iS Low Voltage Motor Control Center (MCC) system. It functions as an industrial PC and protocol converter, providing a central data interface between internal MControl modules and external process control systems such as DCS or PLCs. A single MLink unit can manage internal communication for up to 60 MControl modules.

Features

• Industrial PC-based communication gateway for MNS iS systems.
• Supports up to 60 MControl modules via the internal switchgear bus.
• Multi-protocol support: Modbus RTU/TCP, PROFIBUS DP (V0/V1), and PROFINET IO (for ABB 800xA integration).
• Dual Ethernet LAN ports (LAN1 for fieldbus, LAN2 for network).
• Embedded software modules including Web Server, OPC Server (DA & AE), and Time Synchronization.
• 11 integrated LED status indicators and reset buttons for diagnostics.

Applications

• Oil, Gas, and Petrochemicals: Refining, drilling, and pipeline management.
• Mining, Minerals, and Metals: Conveyor systems, crushing, and smelting operations.
• Power Generation and Utilities: Thermal, nuclear, wind, and solar plant control.
• Chemical Manufacturing: Reactor control, mixing, and pump monitoring.

Technical Specifications

Connections

• Power: Terminal 1 (0V DC), Terminal 3 (+24V DC), Terminal 2 (Not used).
• LAN1: Modbus TCP / PROFINET communication.
• LAN2: Network connection.
• Serial 1: Redundancy interface.
• Serial 2: Modbus RTU interface.
• Fieldbus: PROFIBUS DP Slave interface.
• Internal: Switchgear Bus interface.

Installation Guidelines

• Ensure the device is powered down before inserting or removing any cables.
• For redundant operation, interconnect two MLink units directly using an RS232 Null Modem cable.
• Both units in a redundant pair must have their LAN2 ports connected to the same managed network switch to ensure correct primary/backup handover.
• Use only specified redundant-type switchgear bus connectors to prevent network instability.
• Maintain proper ventilation and avoid installing near high-EMI sources to ensure stable operation.

FAQs

What is the 1TGE120021R0010?
