Description
The I-7540D-MTCP is a device designed for exchanging data between Modbus devices and CAN devices. I-7540D-MTCP is a Modbus TCP server and acts as slave device in Modbus RTU network. It supports four communication modes: Modbus TCP, Modbus RTU, CAN-Ethernet Convert and Pair connection.
The major function of the I-7540D-MTCP is as a CAN to Modbus TCP/RTU gateway. It allows Modbus TCP/RTU devices to communicate with CAN devices on a CAN network. I-7540D-MTCP supports the function codes 0x03/0x04/0x10 of Modbus TCP/RTU for reading and writing CAN messages.
The device supports a transparent, protocol-independent transfer of the CAN messages, thus allowing its implementation into a wide range of possible applications. It can also be used with various higher layer CAN protocols (e.g. CANopen, DeviceNet or other proprietary protocols).
