The I-7540D-MTCP is helpful for data exchanging between the 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 CAN to Modbus TCP/RTU gateway. It allows Modbus TCP/RTU device to communicate with CAN device on a CAN network. I-7540D-MTCP supports the function codes 0x03/0x04/0x10 of Modbus TCP/RTU for reading and writing CAN messages.
Furthermore, The device supports a transparent, protocol-independent transfer of the CAN messages, thus allowing its implementation into a wide range of possible applications. Furthermore, the CAN-Modbus Convertercan be used with various higher layer CAN protocols (e.g. CANopen, DeviceNet or other proprietary protocols). The following figure shows the application architecture for CAN-Modbus Converter.

The PM-213x-CAN series power meter provides the CAN bus interface for users to easily gather the real-time power consumption information in their CAN applications. The PM-213x-CAN provides the Auto-Response mode which responses messages at regular intervals automatically. It makes the communication more efficient when collecting a lot of remote power information. The polling mode offers the precise information of every step required by the monitors. In addition, the PM-213x-CAN also owns the arbitration mechanism which can avoid data collision and error detection.

Features of CAN bus power meter:
  • NXP TJA1042 CAN transceiver
  • Follow CiA CAN 2.0B specification
