Introduction

The IoT (Internet of Things) has been a much discussed topic in recent years. Using the IoT concept, it is easy to integrate the environment of heterogeneous network and digitized all of the things which makes life more convenient. In order to provide more access to IoT industrial applications based on the CAN bus, ICP DAS has developed a new Ethernet product - the ECAN-240.
The ECAN-240 module is a Modbus TCP to 2-port CAN Bus Gateway. It provides communications via the Ethernet based on the Modbus TCP industrial protocol, meaning that the module can be easily integrated with an industrial network. In addition, the ECAN-240 module includes two CAN bus interfaces, so that it can support different CAN applications.
 

Application Architecture:

 ▶ Modbus TCP Server:


▶ Modbus TCP Client:



▶ Pair Connection:



▶ Transparent:

 

Features:

• Fully compatible with the ISO 11898-2 standard.
• Provides support for the CAN bus ID filter function.
• Provides support for the CAN bus bridge mode via configuration.
• Provides support for the CAN bus listen only mode via configuration.
• Provides support for the Modbus TCP Client/Server function via configuration.
• Provides support for TCP/UDP pair connection function via configuration.
• Provides support for web configuration functions.
