  • Page 7: Introduction

    The MB5400 Series are standard Modbus gateways that convert packets between Modbus TCP and Modbus RTU/ASCII protocols. The MB5400 Series support 16 simultaneous TCP masters and 32 simultaneous requests for each TCP master. Each RS-232/422/485 serial port can be individually configured for Modbus/RTU or Modbus/ASCII operation or even different baud rate, allowing both types of networks to be fully integrated with Modbus/TCP within one package.
  • Page 8 MB5400 Series User’s Manual V 1.3 Fig. 1.2 shows three different use cases of the MB5400 Modbus Gateways: the interfacing between Modbus RTU/ASCII serial host to Modbus RTU/ASCII serial devices, the interfacing between Modbus/TCP over Ethernet network to Modbus RTU/ASCII serial devices, and the interfacing between Modbus RTU/ASCII host connected through serial IP over Ethernet (virtual communication port (VCOM)) to Modbus RTU/ASCII serial devices.
