3) Notes:
DVPDNET-SL can only send out 1 explicit message at a time.
Before sending explicit message by using WPL program, we suggest you clear the request message
editing area and response message editing area to 0.
If the slave responds with standard error code, and DVPDNET-SL also consider the communication
being successful, “The communication of explicit message is successful.” will indicate that the
communication has been completed successfully.
