2-4 Installing the Module
Two groups of dipswitches are located on the top edge of the module facing
upward, as shown in Figure 2-2. The set of switches closest to the backplane
connector, labeled S1, is the group used to select interrupt type for points 9
through 16.

Figure 2-2 Location of Interrupt Dipswitch Group

The interrupt type is selected for pairs of input points and cannot be
selected individually. Each pair of dipswitches in the S1 group selects the
interrupt mode for a pair of input points, as listed below.
Switches 1 and 2 control points 9 and 10
Switches 3 and 4 control points 11 and 12
Switches 5 and 6 control points 13 and 14
Switches 7 and 8 control points 15 and 16
You configure each pair of points to detect on-to-off, off-to-on, or either-edge
transitions according to the way you set each pair of dipswitches.
NOTE: This section discusses how to set the dipswitches to select interrupt
types for the configurable input points. To operate as interrupt inputs, these
points must also be enabled individually in the user program using the
internal logic outputs assigned to this task. Refer to Chapter 3 for more
information.
