• Using UDP/IP
The following is the communication procedure when executing SLMP communication with UDP/IP.
With UDP/IP, connections are not established when communication is executed, and whether data is received normally or
not is not checked. Therefore, the line load is low. However, data is less reliable as compared to TCP/IP.
External device
Inverter
According to the request message sent from
the external device, the inverter executes a reading,
writing, or other operation.
Execution of the operation
The external device sends a request message
to the inverter.
Sending a request message
Upon completion of the operation, the inverter sends
a response message to the external device.
Returning a response message
The external device receives the response message
from the inverter and confirms the operation result.
The process is repeated as needed.
Receiving the response message
The external device executes the closing operation
to close the communication.
End of the communication
