Introduction
2Introduction
2.1 Overview
The MB52XX Modbus Gateway is an industrial network device in between Modbus over Serial Line devices and
computer hosts running Modbus/TCP on Ethernet network. Figure 2.1 illustrates a possible network configuration
of the MB52XX Series Modbus Gateway. Fully compliant with Modbus/TCP protocol, the Modbus gateway offers a
convenient solution to connect existing devices or controllers running Modbus serial protocol (Modbus/ASCII or
Modbus/RTU) to an Ethernet network. The MB52XX Series are standard Modbus gateways that convert packets
between Modbus TCP and Modbus RTU/ASCII protocols.
The MB52XX Series supports 64 simultaneous TCP masters. Overall, 247 Servers are supported (TCP, COM and
VCOM). Each RS-232/422/485 serial port can be individually configured for Modbus/RTU or Modbus/ASCII
operation with different baud rate, allowing both types of networks to be fully integrated with Modbus/TCP within
one package.

Introduction
Figure 2.2 shows three different use cases of the MB52XX Series Modbus Gateway:
1) the interface between Modbus RTU/ASCII serial host to Modbus RTU/ASCII serial devices
2) the interface between Modbus/TCP over Ethernet network to Modbus RTU/ASCII serial devices
3) the interface between Modbus RTU/ASCII host connected through Serial IP over Ethernet (virtual
communication port (VCOM)) to Modbus RTU/ASCII serial devices.
