Modbus Serial Port Expander

5102-MBS3-MBM

Descontinuado: Producto no disponible en stock. More Info

The ProLinx Modbus Serial Port Expander module allows you to attach up to three separate Modbus master devices to a single Modbus slave.

The module is designed to act as a multiplexer, allowing simultaneous connections from multiple Modbus masters to a single Modbus slave. A common use for the module is to have an HMI panel and a SCADA application all communicating to the same Modbus slave port of a Modicon processor.

This stand-alone DIN-rail mounted protocol gateway provides a single Modbus Master port and three Modbus Slave ports.

All Modbus serial ports are individually configurable, providing a very powerful and flexible host or device interface solution.

Características y Beneficios

Applications

The Serial Port Expander adds three additional slave ports for a Modbus based device. This allows users to connect SCADA software, HMI, and modems to processors simultaneously. Commands from the host devices are passed through the module and routed directly to the front port of the processor. This allows a port on the processor to be expanded to allow communication with a variety of devices at the same time. Typical applications include SCADA software, local operator interface, and wireless concentrator for remote data collection.

The serial port(s) on the gateway can be individually configured to support the Modbus protocol (RTU or ASCII, Baud rate, etc.).
