I-7540DM-MTCP CR ICP DAS Gateways

Introduction

The I-7540DM-MTCP is helpful for data exchanging between the Modbus devices and CAN devices. I-7540DM-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-7540DM-MTCP is CAN to Modbus TCP/RTU gateway. It allows Modbus TCP/RTU device to communicate with CAN device on a CAN network. I-7540DM-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 Converter can 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.
