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 let all of the things into be digitized making life more convenient. In order to provide additional access to IoT applications related to industry based on the CAN bus, ICPDAS has developed a new Ethernet product, the ECAN-240-FD. The ECAN-240-FD module is a Modbus TCP to 2-port CAN FD (CAN with Flexible Data-Rate) Gateway. As its functionality, that provides communications via the Ethernet based on the Modbus TCP industrial protocol, meaning that the module can be easily integrated with an industrial network. The ECAN-240-FD module includes two CAN bus interfaces, meaning that more various CAN applications can be supported.
The Modbus TCP Server function is used to implement communications between a CAN device and a Modbus TCP Client. When the ECAN-240-FD module is acting as a Modbus TCP Server, the Modbus TCP Client needs to use Modbus commands based on the CAN format in order to access the ECAN-240-FD module. The ECAN-240-FD module will then translate these commands into CAN format messages and send them to the CAN networks. Similarly, when a CAN format message is received from the CAN network, the ECAN-240-FD translates the message into Modbus format, which can then be accessed using a Modbus command.
The TCP/UDP transparent function is used to implement communications between CAN devices and a TCP/UDP Client device. When the communication mode of ECAN-240-FD module is set to TCP/UDP Transparent, the TCP/UDP Client device can use Ethernet commands base on the CAN/CAN FD format, in order to access the ECAN-240-FD module. Then ECAN-240-FD module will translate these Ethernet commands into CAN/CAN FD format messages and send them to the CAN networks. Similarly, when a CAN/CAN FD format message is received from the CAN network, the ECAN-240-FD will translates the message into Ethernet commands and sent it to the connected TCP/UDP client device.
The CAN pair connection application of the ECAN-240-FD module is used to implement communication between two ends of CAN network via Ethernet. It is implemented via UDP protocol for CAN Network #1 can communicate with CAN Network #3 and CAN Network #2 can also communicate with CAN Network #4 in the same manner.
