„ In the beginning of the program, clear the response message editing area and request message
editing area to 0.
„ When M1 = On, DVPDNET-SL will send out request message. Write 0004Hex into Class 99 >>
Instance 1 >> Attribute 2 of the target equipment (node address: 02). If the communication of
explicit message is successful, the slave will return with a response message.
