ProSoft 5302‑MBP‑MCM4 Modbus Plus to Modbus Master/Slave Gateway (4 Serial Ports)

Product Description

The ProSoft 5302‑MBP‑MCM4 is an industrial‑grade, rack‑mountable protocol gateway engineered to bridge seamless, bidirectional communication between Modbus Plus (MB+) networks and up to four independent Modbus RTU/ASCII serial devices (RS‑232/RS‑485). Purpose‑built for mission‑critical industrial automation, process control, and legacy system integration, this module features a configurable DB9 Modbus Plus port (supports Master/Slave modes) and four individually configurable serial ports (each can act as Modbus Master or Slave, with baud rates up to 115.2 kbps, parity/stop‑bit settings, and electrical isolation). It includes an internal shared database for protocol‑agnostic data mapping, built‑in diagnostics with LED status indicators, and compliance with industrial EMI/RFI standards, making it ideal for retrofitting legacy MB+ systems, integrating Modbus sensors/meters/VFDs, and reducing PLC messaging overhead in oil & gas, power generation, manufacturing, and water/wastewater applications.

Key Functions

The 5302‑MBP‑MCM4 gateway delivers robust protocol conversion and data integration with these core features: 1× DB9 Modbus Plus port (Master/Slave configurable, fully compliant with MB+ standards); 4× independent RS‑232/RS‑485 serial ports (each configurable as Modbus RTU/ASCII Master or Slave, electrically isolated for noise immunity); Internal shared database for automatic data mapping between MB+ and Modbus networks, reducing PLC MSG instruction overhead; Individually configurable serial parameters (baud rate, parity, stop bits, flow control) and MB+ network settings (node address, baud rate); Built‑in diagnostics with LED indicators (port activity, network status, fault alarms) and remote configuration via ProSoft Configuration Builder software; Hot‑swappable design for maintenance without system shutdown; Industrial‑grade EMI/RFI filtering, surge protection, and wide temperature operation (-40°C to +70°C).

Application Scenarios

The ProSoft 5302‑MBP‑MCM4 gateway is designed for high‑availability industrial applications including: Legacy Modbus Plus system retrofits to integrate modern Modbus RTU/ASCII sensors, meters, variable frequency drives (VFDs), and PLCs; Process control systems in oil & gas refineries, chemical plants, and power generation facilities requiring bidirectional data exchange between MB+ networks and distributed Modbus devices; Manufacturing automation lines connecting Modbus Plus‑based HMIs/Controllers with Modbus‑enabled robotics, machine vision systems, and production data loggers; Water/wastewater treatment plants integrating Modbus Plus SCADA systems with Modbus RTU/ASCII‑based flow meters, level sensors, and pump controllers; Retrofit projects for Allen‑Bradley PLC‑5/ControlLogix systems needing Modbus Plus to Modbus protocol conversion without replacing existing hardware.
