Appedndix B Setting and Using an Ethernet PLC/Module
B-13
B.4 Data Exchange
A Delta Ethernet master can read/write data from/into a slave by means of instructions. It can also
read/write data from/into a slave by means of tables. The number of data exchanges that models
provide is different. Please refer to section B.1 for more information about the number of devices
exchanging data.
(1) Enable:
Users can enable or disable a data exchange. After a data exchange is enabled, the data will
be exchanged.
(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. The internal registers in different models used to enable data exchanges are
different. Please refer to section B.2 for more information.
(In DVPEN01-SL, the data exchange is executed if CR#13=2, and the data exchanged is not
executed if CR#13=0.)
(3) Station Address-IP Address:
You have to type the IP address of a slave. If the IP address of a slave is 192.168.0.1, and
the station number of the slave is 1, you can type 1 in the first Station Address cell, select
the box in the first Enable cell, and type 192.168.0.1 in the first IP Address cell.
(4) Master Device, Slave Device, and Quantity:
Reading (): Initial reception register in a masterInitial transmission register in a slave
Writing (ïƒ ): Initial transmission register in a masterïƒ Initial reception register in a slave
If a data exchange is enabled, the Ethernet PLC will write data, and then read data.
Quantity: A slave station can send 100 pieces of data at most and receive 100 pieces of data
at most simultaneously.
※ If a device which is not a Delta PLC is connected, users can type a hexadecimal four-digit
MODBUS absolute position in the Slave Device cell.
