Industrial gateways and protocol converters in this category are designed for one clear purpose:
to connect Modbus TCP devices with EtherNet/IP networks quickly, safely, and without costly hardware replacement.
If your field devices communicate via Modbus TCP, while the higher-level PLC, production line, or corporate standard
requires EtherNet/IP, a Modbus TCP to EtherNet/IP gateway is the most efficient integration solution.
Why use a Modbus TCP to EtherNet/IP gateway?
In real industrial projects, this need usually appears in three situations:
(1) modernization of existing lines where Modbus TCP devices are already installed, but a new PLC platform is based on EtherNet/IP,
(2) corporate or end-customer standardization that mandates EtherNet/IP as the primary industrial protocol,
(3) system expansion, where energy meters, analyzers, drives, or I/O modules using Modbus TCP must be integrated into an existing
EtherNet/IP architecture.
In each case, a protocol converter gateway Modbus TCP to EtherNet/IP minimizes downtime, reduces engineering effort,
and allows continued use of proven field devices.
Key benefits for integrators and maintenance teams
A properly selected industrial gateway delivers tangible advantages throughout the project lifecycle:
- Faster commissioning – no need to replace devices or rewrite control logic.
- Lower project risk – existing Modbus TCP field infrastructure remains unchanged.
- Clear diagnostics – protocol separation simplifies troubleshooting and maintenance.
- Scalable architecture – easy expansion with additional Modbus TCP devices and data points.
- CAPEX optimization – reuse installed equipment within an EtherNet/IP environment.
For the end user, this means stable and predictable data exchange between PLCs and Modbus TCP devices,
while fully complying with EtherNet/IP communication standards.
How does a Modbus TCP to EtherNet/IP protocol converter work?
A typical Modbus TCP to EtherNet/IP gateway reads or exposes Modbus TCP registers and maps them into
EtherNet/IP objects or data structures. From the PLC or SCADA perspective, all values appear as native EtherNet/IP data,
while field devices continue to communicate using Modbus TCP.
This protocol separation is critical in industrial environments where deterministic communication, cycle time stability,
and EMC robustness are essential.
Typical applications of industrial gateways Modbus TCP to EtherNet/IP
Solutions from this category are commonly used in:
- production lines – integration of drives, energy meters, quality analyzers, measurement modules, scales, and dosing systems,
- packaging and intralogistics – fast connection of Modbus TCP devices to standardized EtherNet/IP networks,
- plant utilities – monitoring of electricity, compressed air, water, and gas via Modbus TCP data,
- retrofit projects – step-by-step modernization without shutting down entire installations,
- OEM machines – exporting equipment where EtherNet/IP is required, while peripherals use Modbus TCP.
What to consider when selecting a gateway?
To ensure that a protocol converter gateway Modbus TCP to EtherNet/IP operates reliably in your application,
selection should be based on concrete technical requirements:
- Number of data points – total Modbus TCP registers and required update rates.
- Network topology – control cabinet, machine-mounted, or distributed installation.
- Environmental conditions – temperature range, vibration, EMC, and industrial enclosure requirements.
- Commissioning tools – simplicity of mapping and configuration.
- Service and support – availability of documentation and technical assistance.
