Local Setpoints
Local setpoints are target setpoint values for the control loops that are entered by the user
and stored in the controller. The value of local setpoints can be adjusted within the setpoint
limits using the front keypad, or via a serial communications link.
The instrument can has two setpoints for each control loop. The main local setpoint and an
alternate setpoint. The alternate setpoint can be a local setpoint or a remote setpoint from an
auxiliary input. One setpoint at a time is chosen to be active using the setpoint selection.

Communications; Setpoint; Setpoint Lower Limit; Setpoint Upper Limit; and Setpoint Select.

Logical Output Combinations
Any suitable output may be assigned as a logical OR or logical AND output of the alarm and
profile event conditions, and can be configured for reverse or direct action. If OR is chosen,
any of the selected alarms or profile events that are active will cause the output to turn on for
direct acting outputs, or inactive for reverse acting outputs (NOR). If AND is chosen, all of the
selected alarms or profile events must be active to cause the output to turn on for direct
acting outputs, or inactive for reverse acting outputs.
The following table explains the concept of logical OR & AND outputs.
Also refer to: Alarm Operation; Alarm Types; Output Configuration and Profile Events.
