Why Choose the ABB 2TLA020071R9400 GATE-MT Ethernet Gateway?
The ABB 2TLA020071R9400, designated GATE-MT, is a dedicated Ethernet gateway for Modbus TCP designed to provide two-way communication between the ABB Pluto Safety Bus and Ethernet-based industrial automation networks. Classified within the Safety PLC product group, it enables Pluto safety controllers to exchange operational information with compatible PLCs and supervisory control systems using the widely adopted Modbus TCP protocol.
The GATE-MT bridges the Pluto Safety Bus and standard Ethernet using Modbus TCP. Through the gateway, an external control system can read Pluto status, global data and additional data, while supported information can also be transmitted from the external controller to the Pluto system. This makes the gateway particularly useful where machine safety and standard automation need to exchange information while remaining separate control functions.
Powered from 24 V DC, the GATE-MT is designed for industrial control-panel installation and features a compact housing measuring approximately 23 × 108 × 114 mm. It is compatible with a broad range of ABB Pluto controllers and uses the familiar Pluto interface, allowing existing Pluto cabling and Pluto Manager software to be used for servicing and configuration where required.

Reliable Modbus TCP Integration for Pluto Safety Systems
The ABB GATE-MT provides the communication bridge required when information from a Pluto Safety PLC installation must be exchanged with a Modbus TCP-based automation system. A compatible external controller can use the gateway to access Pluto unit status, global data and additional information, enabling safety-system status to be incorporated into machine control, diagnostics, HMI displays and supervisory systems.
The gateway can also support data transfer towards the Pluto system, enabling suitable non-safety information from the external automation controller to be made available to Pluto. ABB documentation includes integration examples with AC500 Ethernet controllers, demonstrating how the GATE-MT can be incorporated into a wider ABB automation architecture using Modbus TCP.
Typical Applications
- Connecting ABB Pluto Safety PLC networks to Modbus TCP systems.
- Integration between machine-safety and standard PLC architectures.
- ABB AC500 and Pluto system integration.
- HMI and supervisory monitoring of Pluto system information.
- Production, assembly and packaging machinery.
- Material handling and automated manufacturing systems.
