Step5:
Check the “Use CAN Message” checkbox and key-in the correct
data in the “Modbus Command” and “CAN Message” fields of the
Utility_A. Click the “Send” button. Then, the Utility_A will automatically
transfer this CAN message to the Modbus RTU command and send it
out through the PC RS-232 COM1 port. After the I-7530A-MR-FD_A
receives this command, it will convert the Modbus RTU message to the
CAN message, and send it to the CAN network. While the
I-7530A-MR-FD_B receives the CAN message transmitted from
I-7530A-MR-FD_A. The message will be converted and stored in the
I-7530A-MR-FD_B until being obtained by the Modbus RTU master.
Then, use the Modbus RTU command (function code 04
hex
) to get the
CAN message by the Utility_B.
Detailed steps of this are shown in the following figure.
