ABB 1TGE120021R0010 MLink Communication Gateway Module for MNS‑iS Intelligent MCC System

1. Basic Information

2. Electrical & Interface Specifications

• On‑board Interfaces: 2 × Ethernet ports, RS‑485 field bus interface, RS‑232 service port, local HMI interface
• Internal bus: MNS‑iS back‑plane bus for communication with MControl motor‑control units
• Supported protocols: Modbus TCP, Modbus RTU, proprietary MNS‑iS internal protocol
• Function: Data collection of motor status, fault alarms, current/voltage measurement values; forward commands from upper system to motor‑control units
• Isolation: Galvanic isolation between field bus and Ethernet interfaces
• No direct process I/O channels; purely communication gateway hardware

3. Environmental Conditions

• Operating temperature: 0 ℃ ~ +55 ℃ (inside MCC cubicle)
• Storage temperature: ‑40 ℃ ~ +85 ℃
• Relative humidity: 5‑95 % RH, non‑condensing
• Approvals & standards: CE, IEC 61850‑3, IEC 61000‑6‑2
• Enclosure rating: IP20
• Dimensions (W×H×D): 280 mm × 130 mm × 210 mm
• Weight: 2.1 kg

4. Main Functions

1. Central communication gateway for MNS‑iS intelligent MCC, collects real‑time status, measurement data and fault events from multiple MControl motor‑protection units.
2. Protocol conversion between internal MNS‑iS bus and standard Modbus TCP / RTU for connection to DCS, SCADA and plant monitoring systems.
3. Route remote control commands (motor start / stop, reset) from upper‑level system down to individual motor‑control units.
4. Local service access via service port for parameter setting, diagnostic readout and firmware upgrade using MNavigate software.
5. Provide system‑wide time‑synchronisation for connected MNS‑iS devices.
6. Product lifecycle status: End‑of‑Life, ABB no longer manufactures new units; procure spare parts with complete part‑number only.

5. Typical Applications

1. Large‑scale industrial low‑voltage motor control centres (MNS‑iS MCC cabinets) for petrochemical, power‑plant auxiliary systems, water‑treatment plants.
2. Real‑time monitoring and remote control of dozens to hundreds of LV motors integrated with plant‑wide DCS/SCADA.

6. Important Notes

1. This gateway is dedicated exclusively for MNS‑iS MCC system; cannot be used as general‑purpose standalone Modbus gateway for third‑party devices.
2. Configuration must be performed with ABB proprietary MNavigate software; no manual DIP‑switch setup.
3. Observe 24 VDC power‑supply range; voltage over‑range will damage module hardware.
4. Full ordering part‑number 1TGE120021R0010 must be used for spare‑part purchasing.
