MGate MB3170-G2/MB3270-G2/MB3470-G2 Series

Introduction

The MGate MB3170-G2, MB3270-G2, and MB3470-G2 are new-generation Modbus gateways that convert between Modbus TCP, RTU, ASCII, and even proprietary or extended Modbus serial protocols. These MGate gateways transparently convert protocols, actively poll connected devices, and cache data in memory. These capabilities make it possible for SCADA systems to retrieve Modbus data directly from the gateway instead of waiting for all Modbus devices to respond, greatly increasing communication performance.

Moxa has developed the MGate Series using the IEC 62443-4-1 secure development life-cycle process ensuring secure connections and management of these gateways within industrial networks.

In addition, the user experience is enhanced by versatile installation options that accommodate diverse mounting and wiring requirements, a rugged design suitable for harsh environments, and easy-to-use configuration and troubleshooting tools for quick maintenance.

Hight-performance Modbus Conversion

MGate MB3170-G2/MB3270-G2/MB3470-G2 gateways operate in either transparent (direct protocol conversion) or agent (polling and caching) mode. Transparent mode converts protocols on a per-request basis. But for larger Modbus systems or when lower latency is needed, agent mode greatly enhances SCADA communication by directly accessing the gateway’s cache.

Features and Benefits

• Supports high-performing and low-latency agent mode to actively poll Modbus devices and cache data

• Supports proprietary Modbus and Modbus extensions for various devices

• Supports Auto Device Routing for easy configuration

• Supports route by TCP port or IP address for different system architectures

• Connects up to 32 Modbus TCP clients (MGate can queue 32 Modbus requests for each Modbus client connected)

• Supports Modbus serial client to Modbus serial server communications

• Ethernet cascading or dual subnet for flexible network system design

• 10/100BaseTX (RJ45) or 100BaseFX (single mode or multi-mode with SC/ST connector or SFP option)

• Modbus communication test tools independant of external software

• Intuitive Modbus diagnostics and traffic monitoring for easy troubleshooting

• Serial port with 2 kV isolation protection (for -I models)

• Supports redundant dual DC power inputs and 1 relay output

• Compliance with IEC 62443-4-2 Security Level 2 requirements

• -40 to 75°C wide operating temperature range (-T models)
