ProSoft Technology 5201-MNET-DFNT – Modbus TCP/IP ↔ DeviceNet Bidirectional Gateway | MVI56E / FLEX Platform
Engineering Background: The 5201-MNET-DFNT is a standalone, DIN-rail-mounted protocol gateway engineered by ProSoft Technology to bridge Modbus TCP/IP Ethernet networks with DeviceNet (CAN-based) fieldbus systems. It eliminates the need for a host PLC to perform protocol translation, offloading conversion logic to a dedicated, deterministic hardware layer. This architecture is critical in brownfield integration projects where legacy DeviceNet device networks must be connected to modern Ethernet-based SCADA, DCS, or MES platforms.
Product Positioning: Targeted at controls engineers and system integrators managing mixed-protocol automation environments — particularly in automotive, food & beverage, material handling, and discrete manufacturing — the 5201-MNET-DFNT provides a hardened, rack-independent solution for real-time data exchange between Modbus TCP/IP masters/slaves and DeviceNet master/slave nodes. It is fully configurable via ProSoft Configuration Builder (PCB) software without requiring PLC programming changes.

Engineering Advantages
- Bidirectional, Simultaneous Translation: Operates as Modbus TCP/IP Client + Server and DeviceNet Master + Slave concurrently — no mode switching required.
- Host-PLC Independent: Standalone operation means zero PLC ladder logic changes; gateway handles all protocol mapping autonomously.
- Deterministic Data Exchange: Configurable scan rates ensure predictable, low-latency data updates between both network sides.
- Flexible Data Mapping: 4000-register internal memory table allows granular, engineer-defined mapping of DeviceNet I/O to Modbus registers.
- ProSoft Configuration Builder (PCB): Free Windows-based software with intuitive GUI for offline configuration, diagnostics, and firmware updates.
- Industrial-Grade Reliability: Wide temperature range, DIN-rail mounting, and CE/UL certifications ensure suitability for harsh panel environments.
- Compact Footprint: 45 mm wide DIN-rail profile minimizes panel space consumption.
System Architecture & Signal Flow
The 5201-MNET-DFNT maintains two independent protocol stacks in firmware, connected via a shared internal register memory table:
- Modbus TCP/IP Side: The gateway’s Ethernet port connects to the plant LAN. As a Modbus TCP/IP Client, it actively polls remote Modbus servers (PLCs, RTUs, drives) and writes data into the internal register table. As a Modbus TCP/IP Server, it exposes the internal register table to upstream Modbus masters (SCADA, HMI).
- Internal Register Table: A 4000-register shared memory space acts as the translation buffer. Engineers define which DeviceNet I/O bytes map to which Modbus register addresses using PCB software.
- DeviceNet Side: As a DeviceNet Master, the gateway polls DeviceNet slave devices (drives, I/O blocks, sensors) and maps their I/O data into the register table. As a DeviceNet Slave, it presents data from the register table to an upstream DeviceNet master scanner.
This architecture ensures that data flows bidirectionally and continuously between both networks with configurable update rates, without any host PLC involvement in the translation process.

Technical FAQ
Q: Can the 5201-MNET-DFNT operate as both Modbus TCP/IP Client and Server simultaneously?
A: Yes. Both roles are active concurrently, allowing the gateway to poll remote Modbus devices while also serving data to upstream Modbus masters at the same time.
Q: Does this gateway require a host PLC (e.g., Allen-Bradley ControlLogix) to function?
A: No. The 5201-MNET-DFNT is a standalone DIN-rail device. It operates independently of any host PLC and requires only 24 VDC power and network connections.
Q: What Modbus function codes are supported?
A: Supported function codes include FC01 (Read Coils), FC02 (Read Discrete Inputs), FC03 (Read Holding Registers), FC04 (Read Input Registers), FC05 (Write Single Coil), FC06 (Write Single Register), FC15 (Write Multiple Coils), and FC16 (Write Multiple Registers).
Q: How many DeviceNet slave devices can the gateway scan as a master?
A: As a DeviceNet Master, the gateway can manage up to 63 slave nodes (node addresses 0–63), subject to network bandwidth and I/O size constraints.
Q: Is ProSoft Configuration Builder (PCB) software included?
A: PCB software is a free download from ProSoft Technology’s official website. No license purchase is required. Konmask can provide configuration assistance as part of pre-sales support.
Q: What is the difference between the 5201-MNET-DFNT and the MVI56E-MNET-DFNT?
A: The MVI56E-MNET-DFNT is a ControlLogix backplane-mounted module requiring an Allen-Bradley rack. The 5201-MNET-DFNT is a standalone DIN-rail gateway with no PLC rack dependency, making it suitable for any brand of PLC or rack-independent installations.
