(4)Program explanations:

„In the beginning of the program, clear the response message editing area and request message editing area to 0.

„When M0 = On, DVPDNET-SL will send out request message, reading Class 1>>Instance 1>> Attribute 1 of the target equipment (node address: 02). If the communication of explicit message is successful, the slave will return with a response message.

„When M0 = On, DVPDNET-SL will only send out request message once. If you would like it to sendout request message again, you will have to change ReqID.

„When the reading is successful, the message responded from the target equipment will be stored in D6000 ~ D6003.
