## PLC-Interface Ethernet Gateway Solution from Phoenix Contact

Phoenix Contact has developed a new Ethernet gateway to simplify communication between PLCs and relays. This modular remote relay system enables communication over a single Ethernet cable, significantly simplifying installation and troubleshooting processes.

### Easy Communication with the Ethernet Gateway

The PLC-Interface Ethernet Gateway supports EtherNet/IP, PROFINET Class C, and Modbus/TCP protocols. It also provides reliability in simple distributed applications with S2 redundancy. The system eliminates classic complex wiring problems, enabling the transmission of different relay control signals via Ethernet from a single PLC.

### System Architecture Working Principle

In an automation system, multiple relays need to be controlled. Normally, each relay control signal would be wired separately, but in this system, the PLC decides which signals go to which relay, and the Ethernet gateway manages this communication. This reduces wiring errors and maintenance processes.

### PLC-Interface Ethernet Gateway Features

• Supports up to 56 digital or analog I/O channels with a modular design
• Compatibility with EtherNet/IP, PROFINET Class C, and Modbus/TCP protocols
• S2 redundant operation support
• Long-term support and new feature additions with firmware updates
• Signal transmission up to 100 meters over Ethernet
• Flexible system design with distributed I/O relay blocks
• Space-saving in the control panel by allowing use near PLCs and relays

### Application and Usage Advantages

This system offers the advantage of controlling relay modules from a separate location. This allows for easy integration as the system expands, without adding a new PLC or control cabinet. Compact and simple wiring ensures more organized use of space in control panels and contributes to quick installation and troubleshooting processes.

### Starter Kits and Expansion Modules

Phoenix Contact also offers starter kits, which include two different relay modules, and expansion modules. These models enable quick system setup and simplification of complex cable networks. Businesses can facilitate the transition to new automation systems or modernize their existing ones.

Phoenix Contact's innovative PLC-Interface Ethernet Gateway simplifies hardware integration and provides high-performance communication in modern industrial automation systems.
