• Even if the same remote module is used, the number of occupied stations varies depending on the point
mode setting.
When 4-point mode is set for a 16-point module, for example, four stations are occupied. In the same way,
two stations are occupied in 8-point mode and one station is occupied in 16-point mode.
• The optimal mode depends on the number of points of remote modules. The number of points of remote
modules, which are used most in the system, should be set for the point mode. This usually minimizes the
number of unused points.
A setting example is as follows.
The system including: 2-point remote station: 1, 4-point remote station: 4, 8-point remote station: 1, 16-
