The I-7530A-MR is a CAN bus to Modbus RTU converter and it allows a Modbus RTU master to communicate with CAN devices on a CAN network. Different from the I-7530A, the I-7530A-MR can be a Modbus RTU slave, and it is more suitable for connecting with the PLC, HMI or SCADA which provide the functions of the Modbus RTU master. Besides, the higher COM baud and full-duplex RS-232/RS-422 transparent communication of the I-7530A-MR solve more difficult problems of applications which may not be touched by the I-7530A. The I-7530A-MR provides three kinds of communication modes, ASCII communication mode, Modbus RTU communication mode, and transparent communication mode.

According to the applications of the different communication modes, the I-7530A-MR can satisfy most of all applications in the data-exchange between the UART and CAN interfaces. It can be used in the application of CAN bus monitoring, building automation, remote data acquisition, environment control and monitoring, laboratory equipment & research, factory automation, etc. The main features are described below:

Note: While testing, the module uses 115.2 kbps baud for the UART communication, and CAN 2.0B 8-byte data frame for the CAN communication. The FPS indicates the receiving capability of the module from CAN to UART.
