The I-7530A-MR-FD supports four communication mod
es: “Normal”,
“Pair connection”, “Modbus Slave”, and “Modbus Master Mode”.
In the Normal mode, it accurately converts ASCII format messages
and CAN messages between RS-232/485/422 and CAN interfaces. In the
Modbus Slave mode, it allows a Modbus master to communicate with
CAN devices on a CAN network. In pair-connection mode, this module
provides the transparent communication between the RS-232/485/422
devices via CAN bus. In the Modbus Master mode, this module is worked
as Modbus Master/CAN module. It can communicate with Modbus slave
device via RS-232/485/422.
