6. Typical Applications

This chapter provides some examples of typical scenarios for the ECAN-240-FD module,

including applications focused on the Modbus Gateway, etc...

6.1. Modbus Gateway

The ECAN-240-FD module is a Modbus TCP to CAN/CAN FD gateway that enables a Modbus

TCP host to communicate with CAN/CAN FD devices through an Ethernet network, and

eliminates the inherent cable length limitations of CAN/CAN FD bus communication.
