(2) Differences between AJ65VBTCU-68DAV and AJ65VBTCU-
68DAVN
The AJ65VBTCU-68DAVN can be handled according to the system. (Refer to
Section 4.4 for details.)
For the AJ65VBTCU-68DAV, the number of stations occupied by the
module was 3 stations.
For the AJ65VBTCU-68DAVN, the number of stations occupied by the
module can be handled as 1 station by setting the mode select switch of
the module to the ver. 2 remote device station.
Further, for the AJ65VBTCU-68DAVN, the number of stations occupied by
the module can also be handled as 3 stations, like the AJ65VBTCU-
68DAV, by setting the mode select switch of the module to the ver. 1
remote device station.
In the system where the maximum number of connected stations of the
master station exceeds 64 stations when the number of stations occupied
by the AJ65VBTCU-68DAVN is handled as 3 stations, use of the
AJ65VBTCU-68DAVN in the above setting can increase the number of
connected remote device stations.
(3) Compatibility between AJ65VBTCU-68DAV and AJ65VBTCU-
68DAVN
There is compatibility when the AJ65VBTCU-68DAVN is used as the ver. 1
remote device station in the existing system. (Refer to Section 4.4 for details.)
When the AJ65VBTCU-68DAV is replaced by the AJ65VBTCU-68DAVN in
the existing system, the replacement can be made without the programs
being modified since the remote I/O signals, remote registers, etc. are the
same.
Set the mode select switch of the module to the ver. 1 remote device
station and use the same station number.
POINT
To handle the AJ65VBTCU-68DAVN according to the system, the mode select
switch of the module must be set, and at the same time, "mode setting" and "station
information (station type)" in the network parameters of GX Developer must also be
set.
Set the network parameters of GX Developer according to the system.
