options. Keep in mind that when the switch is down, it is on (closed);
when it is up, it is off (open). Figure 2.2 shows an example setting; the

Setting Switches in Group 1
In Group 1, switches 1 and 2 determine the actions of the KP3 and PLC–3
controller if either should fault for some reason. Switches 3 and 4 are
used if you are using your KP3 in a backup system (see Installing Backup
PLC–3s on Data Highway II later in this chapter for more information).
Switches 5 through 8 are reserved for future Allen–Bradley applications
and you should not set them. Table 2.A lists the Group 1 switches and the
setting indications.
