Settoing the MELSEC protocol data exchange
1. Enable MELSEC Protocol
Users can disable/enable the MELSEC protocol by unselecting/selecting the Enable MELSEC Protocol
checkbox. After the MELSEC protocol is enabled, data exchange will be carried out according to the data
which has been set.
2. Enable Condition
Users can select Always Enable or Program Control . If Always Enable is selected, DVPEN01-SL will
execute data exchange continuously until the setting in DCISoft is changed. If Program Control is selected,
DVPEN01-SL will execute data exchange according to the program setting (CR#13=2: Executing data
exchange; CR#13=0: Stopping executing data exchange).
3. Slave ID and IP address
Users need to type the IP address and the slave ID of a Mitsubishi device which supports the MELSEC
protocol. For example, the users can type the slave ID 1 and the IP address 192.168.0.1. If data exchange is
executed, DVPEN01-SL will exchange data with the device whose slave ID is 1 and whose IP address is
192.168.0.1 by means of the MELSEC communication.
4. Delta Device , Mitshbishi Device , and Quantity
Reading (

): Start address of the Delta device’s receiving register

Start address of the Mitsubishi device’s
sending register
Writing (

): Start address of the Delta device’s sending register

Start address of the Mitsubishi device’s
receiving register
When data exchange is executed, DVPEN01-SL executes the writing (

) first before the reading (

).
Quantity: A slave is able to send and receive the data in 100 consecutive registers at the same time.
