Note The event input data can be changed from the default setting even
if there is no event input terminal (external input). By changing the
default setting, the event input assignment parameters will be dis-
played at the Controller display and can be set from the Controller.
12. Changing the Event Input Assignment Function
Select the setting for the event input assignment.
When a work bit is selected as event input data, Communications Write
Enable/Disable cannot be assigned to an event input.
13. Changing Control Output and Auxiliary Output Settings
Control output and auxiliary output assignments can be changed. The
items that can be changed depend on the Controller model. For details, re-
fer to 3-5-3 Assigned Output Functions.
Assigning a work bit to either a control output or to an auxiliary output is
also considered to be the same as assigning an alarm. For example, if
work bit 1 is set for the Auxiliary Output 1 Assignment parameter, then
alarms 1 to 3 have been assigned.
