C. Consistency Between a Data Exchange Table and the Network Created in NWCONFIG
The device types shown in the data exchange table in the PLC Link Table Editor window are consistent
with the device names shown in the working area in NWCONFIG. Besides, if a slave station address is
assigned to a port of a network module, the name of the PLC to which the network module is connected
will be shown.
Only AH500 series CPU modules allow 450-word data to be exchanged. As a
result, if the 450 words (AH Only) option button in the Transfer Capacity Mode
section is selected, the DVP series PLCs and the other devices can not execute
a PLC Link. The users can only select M devices, D devices, or L devices in the
Read/Write section. The device types selected in the Read/Write section do not
have to be the same.
If the master station selected is a DVP series PLC, the 16 words option button in
the Transfer Capacity Mode section can be selected. If the 16 words option
button in the Transfer Capacity Mode section is selected, the starting device
address in the Read/Write section will be a certain special data register, and the
users can only specify a data length.
If the slave station selected is a Modbus device, the devices used will be
represented by hexadecimal addresses, and the users can select word devices
or bit devices.
If the 450 words (AH Only) option button is not selected, the users can only
select D devices in the Read/Write section after the Synchronic R/W checkbox
is selected.
