This section explains the concept of the settings required for system configuration, i.e.,
point mode setting and number of occupied stations setting.
The point mode setting sets the number of points that can be controlled for each
occupied remote station in the CC-Link/LT.
The point mode has three different modes: 4-point mode, 8-point mode, and 16-point
mode. If the number of occupied stations is the same, the number of remote stations that
can be controlled in the CC-Link/LT changes depending on the setting of the point mode.
Note that, when connecting a remote device station to the CC-Link/LT system, set the
16-point mode in the point mode setting for the CC-Link/LT.
This section explains a simple setting method of the point mode setting and number of
occupied stations setting.
As the point mode, use the 4-point mode. According to the number of I/O points of the
remote station, refer to the following table and set the number of occupied stations.
Number of Occupied Stations Setting
(4 occupied stations
POINT
Since the default setting is the 8-point mode, change it to the 4-point mode.
This section explains the point mode setting and the application method for number of
occupied stations setting.
(1) If the number of occupied stations is set the same, the number of controllable remote
stations changes depending on the point mode setting, as the following table shows.
2 Occupied
Stations
12 stations
6 stations
3 stations
(2) If the remote module is the same, the number of occupied stations changes due
to the point mode.
For example, if a 16-point module is used, the occupied station number changes
from 4 occupied stations to 2 occupied stations to 1 occupied station when the point
mode changes from the 4-point mode to the 8-point mode to the 16-point mode.
