1. Overview

1.1. Introduction

This guide discusses ICDM--RX/MOD Industrial Gateway configuration for the ICDM--RX/MOD running the
Modbus Router application.
The Modbus Router application provides enhanced connectivity from a wide variety of Modbus masters to a
wide variety of Modbus slaves, advanced Master-to-Master connectivity, and connectivity from private Modbus
serial networks to public Modbus networks.
Supported Modbus masters include:
• Modbus/TCP
• Modbus/RTU serial
• Modbus/ASCII serial
• Modbus/ RTU
• Modbus/ASCII over Ethernet TCP/IP
Supported Modbus slaves include:
• Modbus/TCP
• Public and private Modbus/RTU serial
• Public and private Modbus/ASCII serial
Connectivity can be easily achieved between any master(s) and any public slave(s) anywhere on an Ethernet
network. Combined with a ICDM-RX/MOD running the Modbus/TCP application, both serial and Ethernet TCP/
IP Raw/ ASCII devices can be accessed anywhere on a network from any Modbus master.
Modbus Router was designed to greatly enhance system maintenance capabilities. Included are
comprehensive device and port specific diagnostic web pages that display status, message response timing,
time-outs, other error counts, and overall message statistics. A serial log is also included to provide message
level diagnosis for serial devices.
