The Moxa MGate EIP3170-T is an industrial 1-port gateway specifically designed for converting between the DF1 protocol and EtherNet/IP. It serves as a bridge between older serial control systems, particularly Allen-Bradley PLCs, and modern Ethernet-based networks. This enables the integration of legacy devices into current automation environments without replacing existing serial devices. Support for PCCC objects ensures compatible communication with Rockwell Automation software such as RSLinx, simplifying integration into existing control architectures.

Applications
This gateway is designed for industrial applications requiring a connection between serial devices and EtherNet/IP networks. Typical use cases include connecting older PLC systems, such as Allen-Bradley PLCs, to modern networks to enable data transmission, remote maintenance, or monitoring. The serial redirector function allows parallel operation of EtherNet/IP and serial masters, enabling redundant or hybrid control systems. The use of virtual COM ports over the network supports integration into existing software environments that rely on serial interfaces.

Functions and Features in Detail
The device supports up to 16 simultaneous EtherNet/IP client/server pairs and up to 8 DF1 clients, enabling high parallel processing capability. The serial interface includes a DB9 connector for RS-232 and a terminal block for RS-422/485, allowing connection to various serial devices. Serial parameters are flexibly configurable: baud rate from 1200 bps to 921.6 kbps, 8 data bits, parity options (none, even, odd), stop bits (1 or 2), and flow control via RTS/CTS and DTR/DSR (RS-232 only). Integrated traffic monitoring for EtherNet/IP and DF1 enables efficient troubleshooting and network monitoring.

Technology Explained Simply
The gateway features two Ethernet ports (10/100BaseT(X), RJ45, Auto MDI/MDI-X) for connection to an EtherNet/IP network. Power supply is via dual DC inputs ranging from 12 to 48 VDC, allowing flexible connection to various industrial power sources. Optical isolation protects the device from electrical interference and voltage spikes. DIP switches allow setting of terminator and resistance values, facilitating adaptation to different network topologies. Ethernet cascading enables linking multiple gateways to form larger networks.

Compatibility and Accessories
The device is compatible with EtherNet/IP (PCCC) and DF1 (Transparent, Full Duplex). Support for PCCC objects ensures communication with Rockwell Automation software. The serial interfaces enable connection to legacy devices communicating via RS-232, RS-422, or RS-485. The serial redirector function allows simultaneous use of EtherNet/IP and serial masters, increasing flexibility in system design. The use of virtual COM ports over the network supports integration into software relying on serial interfaces.

Mounting and Installation
The device is housed in a robust enclosure with a plastic cover and metal base, designed for industrial environments. The protection rating IP30 protects against contact with moving parts and larger solid objects, but not against splashing water or dust. Dimensions are 29 x 89.2 x 124.5 mm (with mounting), allowing installation in standard 19-inch racks or on panels. Installation is guided by the included quick installation guide, which describes configuration and commissioning.

Operational Advantages
The high number of simultaneous EtherNet/IP and DF1 connections enables efficient use in complex control systems. Integrated traffic monitoring simplifies diagnosis of network issues. Dual DC power inputs and optical isolation increase reliability in electrically harsh environments. Support for virtual COM ports over the network allows use of existing software solutions without application modifications. The 5-year manufacturer warranty underscores the device's reliability.
