Features:

  • Multi-Format Dual-Protocol Translation Layer
  • Bi-Directional Multi-Client/Server Flexibility
  • Driver-Level Word Buffering & Direct CIP Mapping
The PROSOFT 5201-MNET-DFNT serves as an intelligent data translation bridge, breaking down protocol barriers between Modbus TCP/IP architectures and Rockwell Automation EtherNet/IP infrastructures. It eliminates the need for expensive, proprietary hardware expansions, allowing heterogeneous PLCs, instruments, and SCADA systems to execute real-time, deterministic cross-network data exchanges smoothly.

Offering maximum topology adaptability, the network drivers within the PROSOFT 5201-MNET-DFNT can be independently deployed in concurrent Client and Server configurations. It accepts up to 20 Modbus server connections on ports 502/2000 and executes fully customizable command polling lists of up to 100 commands per client to fit dense field layouts easily.

Equipped with an internal memory cache scalable up to 1,000 words, the PROSOFT 5201-MNET-DFNT processes native 0x4C (Read) and 0x4D (Write) CIP explicit services directly. It maps memory blocks straight into ControlLogix, SLC, or PLC-5 register ranges, drastically reducing network bandwidth consumption while requiring absolutely zero complex ladder logic programming.

The 5201-MNET-DFNT PROSOFT Modbus TCP/IP to EtherNet/IP ProLinx Communication Gateway may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Designed for multi-system interoperability, the PROSOFT 5201-MNET-DFNT provides seamless vertical and horizontal data integration, allowing legacy Modbus TCP/IP devices to communicate bidirectionally with modern Rockwell Automation architectures. Built inside a sturdy, heavy-duty extruded aluminum housing, the module delivers outstanding mechanical ruggedness and continuous-duty reliability, ensuring maximum uptime across diverse factory environments.

Featuring advanced dual-protocol versatility, the network drivers on the PROSOFT 5201-MNET-DFNT function independently and can be simultaneously configured as Client (Master) or Server (Slave) nodes. The Modbus TCP/IP implementation natively supports both MBAP and Encapsulated formats across multiple concurrent connections, while the EtherNet/IP driver utilizes CIP explicit messaging to interface effortlessly with ControlLogix, SLC, PLC-5, and legacy PLC2 processors.

System integrators benefit from an integrated, high-capacity internal database mapping up to 1,000 words, allowing precise memory allocation and swift data buffering between industrial control loops. Backed by 1500 Vrms electrical isolation, hardware-level broadcast storm protection, and deep per-command diagnostic subroutines, this module eliminates data transmission bottlenecks and protects critical control loops from electromagnetic noise on active plant floors.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What protocols and register services are supported by the PROSOFT 5201-MNET-DFNT for PLC data table mapping?
The PROSOFT 5201-MNET-DFNT natively supports full Modbus TCP/IP (MBAP on service port 502 and Encapsulated formats on port 2000) alongside EtherNet/IP explicit messaging. For direct Rockwell Automation integration, it maps registers using standard CIP Data Table services (0x4C Read / 0x4D Write), establishing native compatibility with ControlLogix, SLC, PLC-5, and legacy PLC2 processors, as well as Modbus-compliant Schneider Electric platforms.
How does the PROSOFT 5201-MNET-DFNT physically route network data, and what configuration interfaces are provided?
The PROSOFT 5201-MNET-DFNT is equipped with a single 10 Base-T half-duplex RJ45 Ethernet port for protocol communications, protected by 1500 Vrms galvanic isolation and a built-in hardware resilient broadcast storm threshold (≤5000 ARP frames/sec). For local module engineering, parameter adjustments, and firmware configuration, the gateway features a separate, dedicated front-panel DB-9M RS-232 serial configuration port.
What level of diagnostic depth does the PROSOFT 5201-MNET-DFNT offer for system testing and loop troubleshooting?
The PROSOFT 5201-MNET-DFNT provides discrete command-level diagnostic tools, reporting dedicated error codes and status data individually for every command across its 100-entry client command list. Maintenance technicians can map these status data registers and command error pointers directly back into their control application, complemented by clear, front-panel multi-status LED indicators that track physical power, hardware fault states, and application communication traffic.
Can the PROSOFT 5201-MNET-DFNT map complex variables like floating-point values between multi-vendor SCADA networks?
Yes, the PROSOFT 5201-MNET-DFNT acts as a fully customizable internal data buffer that easily handles advanced data types. Engineers can configure Modbus data type starting address offsets, floating-point start addresses, and corresponding internal database offsets, enabling third-party Modbus TCP/IP SCADA or DCS systems to aggregate floating-point process variables safely from EtherNet/IP loops via the gateway’s 1000-word register space.
What are the thermal parameters and cabinet spacing considerations when deploying the PROSOFT 5201-MNET-DFNT?
The PROSOFT 5201-MNET-DFNT is rated to operate dependably within industrial ambient temperatures ranging from -20°C to 50°C (-4°F to 122°F) and can tolerate relative humidity levels between 5% and 95% without condensation. Because it uses a passive cooling, rugged extruded aluminum chassis, installers should ensure standard thermal clearance on the 35mm DIN rail inside sealed enclosures, especially when mounted near heavy heat-generating equipment like VFDs.
