Bộ chuyển đổi Modbus TCP sang 2 cổng CAN Bus ICP DAS ECAN-240 CR

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.

The ECAN-240 module is a Modbus TCP to 2-port CAN Bus 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 module includes two CAN bus interfaces, meaning that more various CAN applications can be supported, such as a CAN bridge or a CAN message router. The CAN message router function means that the ECAN-240 module can be used to connect to four different CAN networks, ensuring they can communicate with each other.

Modbus TCP Server:

The Modbus TCP Server function is used to implement communications between a CAN device and a Modbus TCP Client. When the ECAN-240 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 module. The ECAN-240 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 translates the message into Modbus format, which can then be accessed using a Modbus command.

Modbus TCP Client:

The Modbus TCP Client function is used to implement communications between a CAN Bus and a Modbus TCP Server. When the ECAN-240 module is acting as a Modbus TCP Client, it can access the Modbus TCP Server via the command configuration. When the ECAN-240 module receives I/O data, it will forward it to the remote CAN devices for analysis, control, or other operations. Once configured, the ECAN-240 module is also able to access the Modbus TCP Server via a CAN message.

Pair Connection:

The Pair Connection function is used to implement communication between two ends of CAN network. CAN Network #1 can communicate with CAN Network #3 or CAN Network #4 using pair connection configuration. Similarly, CAN Network #2 can also communicate with CAN Network #3 or CAN Network #4 in the same manner. The pair connection function on the ECAN-240 module is implemented via either the TCP or the UDP protocol.

TCP/UDP to CAN Transparent Communication:

The Transparent option is to see as a half-pair connections. The TCP/UDP packet is in CAN format and contains the CAN ID. This is useful because it allows custom TCP/UDP programs to be developed that can directly access the ECAN-240 module for specific applications.
