Data Exchange - Delta DVPEN01-SL Operation Manual

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
Check/uncheck the station addresses to enable/disable data exchange. The station address can be
selected individually. For example check Station Address 1 to enable the data exchange and uncheck the
Station Address 2 to disable the data exchange as the the image shown below. This can also be achieved
by setting up CR20~21. Please refere to chapter 4.2 in this manual for more information.
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.
