Ethernet Communication Module DVPEN01-SL



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.
