The PLX31-EIP-MBTCP gateway is designed to solve one of the most common challenges in industrial automation: protocol incompatibility between different devices and control systems.
In modern factories, it is common to have a mixture of EtherNet/IP-based controllers and Modbus TCP devices such as drives, sensors, power meters, and legacy PLC systems. Without a gateway, these systems cannot communicate directly.
The PLX31-EIP-MBTCP solves this problem by acting as a translation layer. It maps data points between the two protocols in real time, ensuring continuous and reliable communication.
The device operates transparently within the network, meaning it does not require changes to existing PLC logic beyond configuration of data mapping rules. This makes it a practical solution for system upgrades and retrofits.
Enables communication between EtherNet/IP and Modbus TCP systems.
Supports fast and deterministic industrial data mapping.
PC-based setup allows flexible mapping without complex programming.
Allows legacy and modern systems to operate together seamlessly.
DIN rail mounting saves panel space and simplifies installation.
Designed for continuous industrial use with high communication reliability.
LED indicators and internal diagnostics simplify troubleshooting.
Allows different automation systems to communicate without replacing existing hardware.
Eliminates the need for complete system redesign when integrating new equipment.
Simple configuration reduces commissioning time.
