Introduce The Product Of Modbus/TCP to CAN converter_GCAN

1. Introduction

1.1 Overview

The GCAN-205 is a CAN-Bus and ethernet converter. GCAN-205 converter ethernet-side integrated Modbus TCP protocol. GCAN-205 can convert the data between CAN-Bus and Modbus TCP. With this converter, equipment that used Modbus TCP protocol can connect to CAN-Bus without changing the hardware structure, this makes multi-Bus interconnection very flexible, and extends the application scope of CAN-Bus.
