The MGate EIP3270I from Moxa is an industrial 2-port gateway that enables communication between the EtherNet/IP (PCCC) protocol and the DF1 protocol. It serves as a bridge between modern Ethernet-based control systems and older serial PLC systems using DF1. With serial isolation of 2 kV and a robust housing, the device is designed for use in automation technology, where high electrical immunity and mechanical durability are required.

Applications
This gateway is suitable for industrial environments where existing DF1-based PLC systems need to be connected to modern EtherNet/IP networks. This includes applications in manufacturing automation, process control, and machine building, where bidirectional data transfer between different control levels is necessary. Support for up to eight DF1 clients allows simultaneous communication with multiple PLC devices, simplifying integration into complex systems.

Functions and Features in Detail
The MGate EIP3270I features two serial RS-232/RS-422 interfaces with DB9 male connectors, enabling flexible connection to various serial devices. The baud rate can be set between 1200 bps and 921.6 kbps, with configurable data bits (8), parity (none, even, odd), and stop bits (1, 2). Flow control is supported via RTS/CTS and DTR/DSR (RS-232 only). The 2 kV serial isolation protects against electrical interference and potential differences. Additionally, two Ethernet ports with 10/100BaseT(X) and RJ45 connectors are provided, supporting Auto MDI/MDI-X to simplify cabling.

Technology Explained Simply
Configuration of the gateway is performed via the MGate Manager software or a Telnet console, enabling flexible and centralized management. Protocol support includes EtherNet/IP (PCCC) and DF1 in transparent, full-duplex mode. Bidirectional communication ensures data can be transferred both from the PLC to the network and vice versa. The device features a relay output with a maximum load of 1 A at 30 VDC (resistive), suitable for simple control tasks. Power supply is 12 to 48 VDC, with power consumption of 510 mA at 12 VDC.

Compatibility and Accessories
The gateway is designed for use with PLC devices supporting DF1, enabling their connection to EtherNet/IP networks. Configuration via MGate Manager or Telnet console allows integration into existing network management systems. Support for SNMPv1, TCP/IP, UDP, and ARP enables network monitoring and management. MIBs RFC1213 and RFC1317 are implemented to support standard network management functions.

Mounting and Installation
The device has a housing made of plastic cover and metal base, designed for industrial environments. The protection rating IP30 protects against finger contact and solid foreign objects, but not against water or dust. Dimensions are 29 × 89.2 × 124.5 mm (with holder) or 29 × 89.2 × 118.5 mm (without holder). Weight is 380 g. Mounting is typically done in enclosures or on DIN rails, with mechanical durability ensured according to IEC 60068-2-x.

Operational Advantages
The MGate EIP3270I offers a reliable and low-maintenance communication solution for industrial applications. The high MTBF of 1,204,573 hours (Telcordia SR332) demonstrates high operational reliability. Certifications include EN 55032/35, CISPR 32, FCC Part 15B (EMC), IEC 61000-4-x (EMS), IEC/UL 60950-1, EN/UL 62368-1, UL 508 (safety), as well as ATEX, IECEx, Class I Div 2 (hazardous areas), ensuring suitability for various industrial environments, including potentially explosive areas. Operating temperature is 0 to 60 °C, and storage temperature is -40 to 85 °C, allowing use in a wide range of climatic conditions. Humidity of 5–95 % (non-condensing) is also typical for industrial applications.

Warranty
The device is supplied with a 5-year warranty. Further information is available at www.moxa.com/warranty.
