The I-7530A-MR 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.

 

• Control System
• Building Automation
• Factory Automation
• Distributed data acquisition

 

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.
