The Moxa MGate EIP3170I-T is an industrial protocol gateway specifically designed for converting between the EtherNet/IP network protocol and the DF1 serial protocol. It enables the integration of Allen-Bradley PLC systems into modern Ethernet-based networks while continuing to utilize existing serial infrastructures. The device features a serial interface with RS-232 (DB9) and RS-422/485 (terminal block) as well as two Ethernet interfaces with 10/100BaseT(X) and RJ45 connectors. Support for PCCC objects on CIP allows direct communication with SCADA systems such as RSLinx. The serial redirector function enables parallel operation of EtherNet/IP and DF1 masters, making it suitable for redundant systems. Using Moxa’s Real COM driver, up to four virtual serial ports can be configured to continue using existing software environments.

Applications
This gateway is designed for industrial applications, particularly in environments where older DF1-based control systems need to be connected to modern EtherNet/IP networks. It is suitable for production facilities, manufacturing lines, and automation systems where seamless communication between different protocols is required. The robust construction and certifications for hazardous areas (ATEX, Class I Div 2, IECEx) also make it suitable for applications with higher safety requirements. The marine certification (DNV) applies only to the EIP3170 model.

Functions and Features in Detail
The device supports up to 16 simultaneous EtherNet/IP client/server pairs, with each client/server pair capable of handling up to 16 pending requests. Additionally, up to 8 DF1 clients can be operated simultaneously. Serial parameters include a baud rate from 1200 bps to 921.6 kbps, 8 data bits, parity options (none, even, odd), 1 or 2 stop bits, and flow control via RTS/CTS and DTR/DSR (RS-232 only). Integrated Ethernet cascading simplifies network cabling, while DIP switches on the underside allow adjustment of termination and pull resistors.

Technology Explained Simply
Optical isolation of 2 kV (for I models) protects the device from electrical interference and voltage spikes, increasing reliability in industrial environments. Power supply is provided via an input range of 12 to 48 VDC, with current consumption up to 555 mA at 12 VDC. An integrated relay output with 1 A @ 30 VDC (resistive load) enables additional control functions. The housing consists of a plastic lid and a metal base, with an IP30 protection rating. The operating temperature for the T model ranges from -40 to 75 °C, making it suitable for extreme environments.

Compatibility and Accessories
The gateway is compatible with EtherNet/IP and DF1 protocols and can be integrated into existing networks with Allen-Bradley PLC systems. Support for PCCC objects on CIP enables direct communication with SCADA systems. The serial redirector function and Real COM driver support the use of existing software environments. Certifications include EMC standards (EN 55032/35, CISPR 32), immunity (IEC 61000-4-2~11), safety standards (IEC 60950-1, UL 60950-1, EN 62368-1, UL 508), as well as certifications for hazardous areas (ATEX, Class I Div 2, IECEx) and marine applications (DNV for EIP3170). Vibration and shock tests according to IEC 60068-2-6, -2-27, -2-64 ensure mechanical robustness.

Mounting and Installation
The device is designed in a compact format with dimensions of 29 × 89.2 × 124.5 mm (with mounting ears) or 29 × 89.2 × 118.5 mm (without ears). Mounting is achieved via integrated mounting ears, allowing attachment to standard DIN rails. Configuration is performed using the DIP switches on the underside and Moxa’s software tools. Power supply is provided via an external DC power supply in the range of 12 to 48 VDC.

Operational Advantages
The high MTBF (up to 1,344,456 hours for the EIP3170 series) demonstrates the device’s high reliability. Support for multiple simultaneous client/server pairs and DF1 clients enables efficient use in complex installations. Optical isolation and robust construction increase lifespan and operational safety. Integrated Ethernet cascading reduces the number of required switches and simplifies network architecture. Certifications for hazardous areas and marine applications extend the range of use in demanding environments.

Scope of Delivery
The device is delivered with a quick start guide and a warranty card. The warranty period is 5 years.
