The Moxa MGate EIP3170I is an industrial-grade gateway for protocol conversion between EtherNet/IP and DF1. It is designed for integrating Allen-Bradley PLC systems into modern EtherNet/IP networks, particularly in environments where older serial devices are still in operation. Devices from the EIP3170/EIP3270 series enable reliable communication between different control systems and support connection to SCADA systems such as RSLinx via PCCC objects on the EtherNet/IP CIP protocol.

Applications
This gateway is designed for industrial applications requiring a bridge between modern Ethernet-based control systems and older serial communication protocols such as DF1. It is particularly suitable for production environments where existing machines with RS-232/RS-422/RS-485 interfaces need to be connected to new, Ethernet-based control systems. Support for up to 16 simultaneous EtherNet/IP connections and 8 DF1 client connections enables flexible use in complex networks with multiple control and monitoring systems.

Functions and Features in Detail
The MGate EIP3170I features a serial redirector function that allows a serial and an EtherNet/IP master to operate simultaneously on the same serial interface. This reduces the number of required physical interfaces and simplifies network architecture. Virtual COM port assignment via ProCOM enables use of the serial interface through a PC- or server-based operating system, facilitating integration into existing software solutions. An integrated protocol monitor supports configuration, monitoring, and fault diagnosis by displaying data traffic in real time.

Technology Explained Simply
The device offers two Ethernet interfaces (10/100BaseT(X), RJ45) with Auto MDI/MDI-X, enabling flexible network connectivity. The serial interface of the EIP3170I includes a DB9 connector (RS-232) and a terminal block for RS-422/RS-485, allowing connection to various serial devices. The baud rate can be set between 1200 bps and 921.6 kbps, with data bits fixed at 8, parity set to None, Even, or Odd, and stop bits set to 1 or 2. Flow control is supported via RTS/CTS and DTR/DSR (RS-232 only). Power supply is provided via a redundant DC input ranging from 12 to 48 VDC, with maximum current draw of 555 mA at 12 VDC.

Compatibility and Accessories
The gateway is compatible with EtherNet/IP and DF1 protocols and supports DF1 modes Transparent and Full Duplex. Integration into existing control systems is facilitated by support for PCCC objects on the CIP protocol, enabling direct communication with SCADA systems such as RSLinx. The devices are designed for industrial environments and meet EMC requirements (EN 55032/35, CISPR 32, IEC 61000-4-x) as well as safety standards (UL 60950-1, EN 62368-1, UL 508). Additionally, they are certified for use in hazardous areas (ATEX, IECEx, Class I Division 2).

Mounting and Installation
The device features a robust industrial housing with a plastic lid and metal base, rated to IP30. Dimensions are 29 x 89.2 x 124.5 mm (with mounting flanges), making it suitable for installation in standard 19-inch racks or on panels. Installation is supported by the included quick installation guide, which assists with configuration and commissioning. DIP switches allow setting of termination and pull resistors, facilitating adaptation to various network environments.

Operational Advantages
High availability is ensured by redundant power supply and support for up to 16 EtherNet/IP connections. The MTBF is up to 1,344,456 hours (according to Telcordia SR332), indicating high reliability. The devices are designed for operating temperatures of 0 to 60 °C (standard) or -40 to 75 °C (Wide Temp models), making them suitable for use in demanding climatic conditions. Relative humidity may range from 5 to 95 %, provided no condensation occurs. Vibration and shock resistance according to IEC 60068-2-6, -2-27, -2-64 ensures reliable operation under industrial conditions.

The device is delivered with a quick installation guide and a warranty card. The warranty period is 5 years.
