PLX31-EIP-MBS4 | ProSoft | Passerelle de communication série à quatre ports

Description

The PLX31-EIP-MBS4 is an industrial-grade communication gateway designed to establish bi-directional data exchange between EtherNet/IP networks and Modbus Serial protocols. By acting as a protocol converter, this module permits EtherNet/IP-enabled controllers, such as Rockwell Automation Logix processors, to seamlessly read and write data to Modbus Serial devices. The gateway features four isolated serial ports, allowing independent configuration for RS-232, RS-422, or RS-485 electrical interfaces. This flexibility enables high-density integration of field instruments, power meters, drives, and flow controllers into modern control systems.

Engineered for demanding industrial environments, this interface module supports both EtherNet/IP Class 1 I/O connections for real-time control and Class 3 messaging for diagnostic data transfer. The dynamic data mapping capabilities allow engineers to optimize throughput, ensuring minimal latency between networks.

Features

• Four fully independent, isolated serial ports supporting RS-232, RS-422, and RS-485 configurations.
• Supports up to 5 EtherNet/IP Class 3 server connections and 8 Class 1 I/O connections.
• Bi-directional data mapping between EtherNet/IP and Modbus Serial networks.
• Configurable serial parameters including baud rate, parity, stop bits, and handshaking.
• Diagnostics and monitoring available via web-based configuration tools.
• Wide operating temperature range suited for unconditioned control cabinets.

Applications

• SCADA and HMI integration with legacy Modbus field devices.
• Power distribution networks integrating Modbus RTU power meters.
• Oil and gas flow metering system communication.
• Water and wastewater remote telemetry integration.
• Industrial manufacturing assembly line automation.

Connections and Interfaces

Installation Guidelines

• Mounting: Install on standard 35mm DIN rails. Verify the locking mechanism is secure.
• Grounding: Connect the dedicated ground terminal on the power connector directly to the panel functional ground using low-impedance copper wire.
• Wiring: Route communication cabling (Ethernet and Serial) away from high-voltage AC lines to prevent electromagnetic interference.
• Clearance: Maintain at least 50mm of clearance at the top and bottom of the module to support proper convective cooling.

Compliance and Certifications

• CE Mark
• UL/cUL Class I, Division 2
• ATEX Zone 2
