Ethernet Communication Module DVPEN01-SL

5.6 Data Exchange

DVPEN01-SL is able to designate a data exchange area for PLC MPUs to exchange and synchronize their data.

 Setting data exchange

1. Enable Data Exchange

Click the box to enable or disable data exchange. Start data exchange after enable it.

2. Enable Condition

You 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. Station Address and IP Address

You have to enter the IP address of DVPEN01-SL at the other end. For example, if you would like

DVPEN01-SL to exchange data with 192.168.0.1, set No. 1 as 192.168.0.1. When the data are being

exchanged, if the value in CR#28 is H’0001, the data will be exchanged with 192.168.0.1.

4. Master Device, Slave Device, and Quantity.

Reading (): Start address of the master’s receiving registerStart address of the slave’s sending register

Writing (): Start address of the master’s sending registerStart address of the slave’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.

 For data exchange, D register is parted into 2 sections, D0000~D4095 and D4096~D9999. Please DO

NOT use different sections for the consecutive sent and received data (start address + number of data).

5. See section 6.9~section 6.11 for more details.
