Linked Device
The users can select a slave station address which belongs to this data exchange group. The device
type displayed in the Device Type box is a model name displayed in the working area in NWCONFIG.
If the slave station address selected is assigned to a port of a network module, the name of the PLC to
which the network module is connected will be shown in the Device Type box. If the slave station
address selected is undefined, or is not involved in the PLC Link constructed, "Unknown" will be
displayed in the Device Type box. Besides, the station address assigned to the master station can not
be selected, and a slave station address can belong to several data exchange groups.

Linked Status
After the users select a slave station address which can be used, they can select the Disable option
button, or the Enable option button in the Linked Status section.

Read
The users can select a device type, type a starting address, and type a data length in the Master
Parameter Setting section. They can select a device type, and type a stating address in the Slave
Parameter Setting section. Generally speaking, the device types selected in the Read section must
be the same, and do not have to be the same as the device types selected in the Write section.

Write
The users can select a device type, type a starting address, and type a data length in the Master
Parameter Setting section. They can select a device type, and type a stating address in the Slave
Parameter Setting section. Generally speaking, the device types selected in the Write section must
be the same, and do not have to be the same as the device types selected in the Read section.
The data in a group of devices can be written into several different groups of devices, but the data in
different groups of devices are not allowed to be stored in the same group of device. Take the figure above
for example. The data in D3100~D3149 in the master station can be written into different slave stations,
but D3000~D3099 in the master station can not receive the data in devices other than D2500~D2599 in
the slave station whose station address is 2. Besides, the device types selected in the Read/Write section
must be the same. However, the limitation on the setting of a data exchange group varies with the master
station/slave station selected or the communication parameters selected.
