Editor
window are numbered. Users can set 16 data exchange groups or 32
data exchange groups, depending on the model selected.
Station
Addr.
The slave station address which belongs to a data exchange group is
indicated. A station address can belong to several data exchange group.
Besides, the station address 0 represents an undefined slave station, and is
not a broadcast station address.
R/W
R: The master station reads the data in devices in a slave station.
W: The master station writes data into devices in a slave station.
Master
Device Data
The range of devices which are used in the master station is indicated.
<=>
<=: The master station reads the data in devices in a slave station.
=>: The master station writes data into devices in a slave station.
Slave Device
Data
The devices which are used in a slave station are indicated. If a slave station
is a user-defined Modbus device, the devices used will be represented by
hexadecimal addresses.
Length
A data length is indicated. A length indicates the number of devices used.
Status
Users can decide whether to involve a data exchange group in data
exchange. If a data exchange group is set incorrectly, the data exchange
group will not be involved in data exchange. If a data exchange group is not
involved in data exchange, the related data will be on a gray ground.
Device Type
The device types shown are consistent with the device names shown in the
working area in NWCONFIG. If a slave station address is assigned to a
network module, the name of the PLC to which the network module is
connected will be shown. Besides, if a slave station is undefined, it is
unknown.
The figure below is an example of a data exchange table. Group #1, group #2, group #4, and group #5 are
involved in data exchange. Please refer to the table below for more information.
