The I-7530A-MR is designed to enable communication between 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.
