ABB 2TLA020071R8000 GATE-P2 Pluto Gateway PROFIBUS-DP Communication Module

ABB 2TLA020071R8000 is the GATE-P2 Pluto gateway designed to provide two-way communication between the ABB Pluto safety bus and a PROFIBUS-DP network. It is part of the ABB Jokab Safety product family and is used as a communication interface between Pluto safety controllers and a larger automation or control system. By connecting the Pluto safety bus to PROFIBUS-DP, the GATE-P2 allows relevant information from the safety control system to be exchanged with another control architecture.

The GATE-P2 is particularly useful in industrial installations where a Pluto safety system needs to communicate with a PROFIBUS-based control environment. The gateway operates as a PROFIBUS-DP slave and uses an isolated PROFIBUS RS485 interface together with the isolated Pluto safety bus. Its compact DIN-rail design allows it to be installed alongside other control and safety components within an industrial control cabinet.

Product Identification

The complete ABB product identification is 2TLA020071R8000, while the extended product type is GATE-P2. ABB product documentation describes the device as a Pluto gateway for PROFIBUS-DP. The primary function is not to act as a standalone PLC, but to provide communication between the Pluto safety bus and PROFIBUS.

The GATE-P2 belongs to a family of Pluto gateways with different fieldbus interfaces. For example, related versions include GATE-C2 for CANopen and GATE-D2 for DeviceNet. The 2TLA020071R8000 designation specifically identifies the PROFIBUS-DP version.

Communication Between Pluto and PROFIBUS

The main purpose of the GATE-P2 is to connect two different communication environments. On one side, the gateway communicates with the Pluto safety bus used by ABB Pluto safety controllers. On the other side, it communicates with a PROFIBUS-DP network. This arrangement allows a Pluto-based safety architecture to exchange information with a supervisory PLC or automation system using PROFIBUS.

The communication is bidirectional. Information can therefore be exchanged between the Pluto system and the PROFIBUS network rather than being limited to a simple one-way signal conversion. The gateway provides the interface required to integrate Pluto safety functions into a broader automation architecture while maintaining the dedicated communication structure of the Pluto safety bus.

Pluto Safety Bus Interface

The Pluto side of the GATE-P2 uses the Pluto safety bus, which is based on CAN communication. The interface is isolated and supports several bus speeds. According to ABB technical documentation, supported Pluto safety bus speeds include 100, 200, 250, 400, 500, 800, and 1000 kbit/s, with automatic speed detection.

This communication arrangement allows the gateway to participate in a Pluto safety system without requiring the PROFIBUS network to directly access the internal Pluto bus structure. The GATE-P2 therefore functions as a dedicated communication bridge between the two network environments.

PROFIBUS-DP Interface

On the fieldbus side, ABB 2TLA020071R8000 provides an isolated PROFIBUS RS485 interface. The gateway operates as a DP-V0 slave and supports PROFIBUS communication speeds up to 12 Mbit/s. The PROFIBUS address is configured using DIP switches, with an address range from 0 to 99.

The use of PROFIBUS-DP makes the GATE-P2 suitable for control systems in which a master PLC or supervisory controller manages field devices and exchanges process information through a PROFIBUS network. The gateway provides the necessary interface for communication between that PROFIBUS master environment and the Pluto safety system.

Electrical Connections

The GATE-P2 has dedicated connections for the Pluto safety bus, PROFIBUS, and the 24 VDC power supply. The Pluto safety bus connection is located at the top of the unit and uses a three-pole terminal. A standard nine-pole PROFIBUS connection is provided at the front of the device, while the 24 VDC power connection is located at the bottom and uses a two-pole terminal.

This arrangement separates the main communication interfaces and power connection around the compact gateway enclosure. Status LEDs provide visual indication of the Pluto safety bus and PROFIBUS communication status, making it easier to identify the operating condition of the communication interfaces during commissioning and maintenance.

Power Supply

ABB specifies a nominal operating voltage of 24 VDC for the GATE-P2. The documented operating range is 24 VDC with a tolerance of -15% to +20%. Current consumption at 24 V is specified as less than 100 mA. ABB documentation also identifies a recommended fuse rating of up to 6 A for the supply circuit.

When installing the gateway, the power supply should be connected according to the applicable wiring instructions. Correct polarity and an appropriate protective arrangement are important because the gateway is an active communication device that requires a stable DC supply for operation.

DIN Rail Installation

The GATE-P2 is designed for installation on a standard 35 mm DIN rail. Its compact dimensions of approximately 22.5 mm wide, 101 mm high, and 119 mm deep allow it to occupy a relatively small space in a control cabinet.

The narrow housing is useful when several Pluto safety components and communication devices are installed in the same cabinet. Adequate space should nevertheless be provided for the PROFIBUS connector, wiring, power connection, and access to the configuration switches. The installation position should also allow the status LEDs to remain visible during commissioning and troubleshooting.

Operating Environment

ABB technical documentation specifies an ambient operating temperature range of -10°C to +55°C for the GATE-P2. The documented transport and storage temperature range is -25°C to +55°C. The enclosure classification is IP20, and the terminal connections are also specified as IP20.

The gateway should therefore be installed in an appropriate control enclosure when used in an industrial environment requiring protection from dust, moisture, or other external influences. The installation environment should remain within the specified operating conditions to maintain the intended communication performance.

Application in Safety Control Systems

The GATE-P2 is intended for installations based on the ABB Pluto safety platform. Pluto safety controllers can be used to monitor and control safety-related functions such as emergency stops, safety switches, light curtains, two-hand controls, and other safety devices. In a larger automation system, the GATE-P2 provides the communication path between this safety architecture and a PROFIBUS-based control system.

For example, a production line may use Pluto safety controllers to manage safety devices distributed around machines while a central PLC communicates through PROFIBUS. The GATE-P2 allows the two systems to exchange the required information, providing a practical interface between the safety-control layer and the wider automation network.

Configuration and Commissioning

During commissioning, the PROFIBUS address must be configured correctly using the DIP switches. The address selected on the GATE-P2 must correspond with the configuration of the PROFIBUS master and the network design. The PROFIBUS communication speed is automatically detected according to the supported bus configuration.

The Pluto safety bus connection should also be checked before starting communication. The correct bus wiring, termination, supply voltage, and compatible Pluto devices should be confirmed according to the system documentation. Status LEDs on the gateway can then be used to verify the operating condition of the two communication interfaces.

System Integration

In a complete automation system, the GATE-P2 does not replace the Pluto safety controller or the PROFIBUS master. Instead, it provides the communication interface between them. This distinction is important when designing the system because the gateway is responsible for communication while safety logic remains within the appropriate Pluto safety architecture.

The gateway can therefore be considered a communication bridge within a larger safety and automation system. Its compact design, isolated interfaces, configurable PROFIBUS address, and support for PROFIBUS-DP make it suitable for integrating Pluto-based safety systems with established PROFIBUS control networks.
