Step5: Check the "Use Modbus RTU Command" 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_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_B receives the CAN
message transmitted from I-7530A-MR_A. The message will be
converted and stored in the I-7530A-MR_B until being obtained by
the Modbus RTU master. Then, use the Modbus RTU command
(function code 04
) to get the CAN message by the Utility_B.
