Bộ chuyển đổi Modbus RTU sang CAN ICP DAS I-7530A-MR

Features

i-7530a-amr applicationThe I-7530A-MR Modbus RTU to CAN converter is helpful for data exchanging between the RS-232/485/422 devices and the CAN devices. It supports three communication modes: “Normal”, “Modbus RTU”, “Pair-connection”. 

In the Normal mode, the I-7530A-MR is designed to unleash the power of CAN bus via RS-232/485/422 communication method. It accurately converts ASCII format messages and CAN messages between RS-232/485/422 and CAN networks. This mode let you to communicate with CAN devices easily from any PC or programmable devices with RS-232/485/422 interface. 

In Modbus RTU mode, it allows a Modbus RTU master to communicate with CAN devices on a CAN network. The following figure shows the application architecture of this mode.

In pair-connection mode, this module provides the transparent communication between the RS-232/485/422 devices via CAN bus. The application architecture may be as follows.
