Digital inputs 1 and 2
combination operation
There are five possible situations that can occur when working with
digital input combinations. Table 5-32 lists these situations and the
resulting action when the switch is active.
In the table:
Enabled means that the parameter is configured and the action
will occur when the digital input is active.
Action Disabled means that the digital input or digital combination
parameter is configured but the action cannot occur
when the digital input is active because the selected
parameter is disabled.
