ProSoft PLX31-EIP-MBTCP ProLinx EtherNet/IP to Modbus TCP/IP Gateway

Product Overview

The ProSoft PLX31-EIP-MBTCP functions as a high-speed communication gateway that bridges EtherNet/IP and Modbus TCP/IP networks. It allows Allen-Bradley Logix processors to exchange data effortlessly with Modbus TCP/IP devices, such as power meters, VFDs, and flow controllers. This unit stands as a critical integration tool for multi-vendor automation environments. We supply this gateway as 100% brand new and original, ensuring maximum network uptime and technical compliance.

Technical Specifications

The PLX31-EIP-MBTCP utilizes a ruggedized hardware platform to maintain high-speed protocol translation under harsh conditions:

• Input Power: 24VDC nominal (Accepts 10 to 36 VDC)

• Current Load: 300 mA @ 24VDC (610 mA maximum at lower voltages)

• Operating Temperature: -25°C to 70°C (-13°F to 158°F)

• Storage Temperature: -40°C to 80°C (-40°F to 176°F)

• Humidity: 5% to 95% RH (Non-condensing)

• Shock Resistance: IEC 60068-2-27 (15G Operational / 30G Non-Operational)

• Vibration Resistance: IEC 60068-2-6 (5G @ 10 to 150 Hz)

• Physical Dimensions: 5.38 x 1.99 x 4.38 inches (13.67 x 5.05 x 11.13 cm)

• Terminal Type: Positive, Negative, and GND Terminals

Engineering Advantages

• Extreme Thermal Resilience: The gateway operates reliably from -25°C to 70°C. This wide temperature range eliminates the need for expensive cabinet cooling or heating in most outdoor or high-heat manufacturing environments.

• Superior Mechanical Durability: Certified to IEC 60068-2 shock and vibration standards, the PLX31-EIP-MBTCP withstands the physical stress of heavy industrial machinery. It maintains stable connections in applications involving mining equipment, compressors, or vibrating conveyors.

• Wide Range DC Input: The power circuit accepts any voltage between 10 and 36 VDC. This flexibility allows engineers to power the device from 12V battery systems or standard 24V industrial rails without requiring specialized voltage converters.

• Compact Footprint for High-Density Racks: At under 2 inches wide, the module maximizes rail space. This compact profile allows for easy retrofitting into existing overcrowded control panels where space is at a premium.

• Protocol Transparency: The PLX31 architecture minimizes data latency during translation. It ensures that critical process variables from Modbus TCP/IP devices reach the EtherNet/IP controller fast enough for real-time logic execution.

FAQs

• Can the PLX31-EIP-MBTCP act as both a Modbus TCP Client and Server? Yes. The gateway supports simultaneous Client and Server roles. It can actively poll Modbus devices while concurrently serving data to other Modbus Masters or EtherNet/IP scanners.

• What is the best way to mount this unit? The hardware includes a standard integrated DIN rail clip. Mount the unit vertically and ensure at least 1 inch of clearance above and below the device to facilitate natural convection cooling.

• Does this unit support Power over Ethernet (PoE)? No. The PLX31-EIP-MBTCP requires a dedicated DC power supply connected to the screw terminals (10 to 36 VDC). It does not draw power from the Ethernet cable.

• How do I configure the protocol mapping? You must use the ProSoft Configuration Builder (PCB) software. This utility allows you to define the internal data map and set up EtherNet/IP Class 1 or Class 3 messaging for seamless integration with Studio 5000 projects.
