Analog Result Variable:
Below messages will be displayed when Analog Variable satisfy safety conditions.
Warnings are displayed in IDLE condition and it is monitored under Inhibit Checkbox (Refer Figure 6-7)
When “Neither” is selected in Alarm/Trip then No Alarm and Trip for Analog Variable is monitored.
Alarm condition occurs if the value of a parameter drops below or rises above the congured Alarm setpoint for a
continuous Cycles.
Trip condition occurs if the value of a parameter drops below or rises above the congured Trip setpoint for a con-
tinuous Cycles.
