Facilitates alarm mode settings for the Alarm Output Discrete/ALM_OUT_D
parameter.

•Low Cutoff/LOW_CUT
• HiHi or LoLo Alarm activates ALARM_OUT_D/HIHI_LOLO
• Hi or Lo Alarm activates ALARM_OUT_D/HI_LO

The Alarm Output Discrete/ALM_OUT_D parameter comprises the 4 alarms (LO,
LOLO, HI, HIHI). The 3 values make it possible to view the current, activated alarm
depending on the alarm selected.
Options:
• LOW_CUT alarm (default): The ALM_OUT_D output returns 1 if the LOW_CUT
function restricts the measured value to 0. Otherwise the ALM_OUT_D output is 0.
• HIHI/LOLO collective alarm: The ALM_OUT_D output returns 1 if the measured
value corresponds to the HIHI limit value or overshoots this value if the measured
value corresponds to the LOLO limit value or undershoots this value. The output
returns 0 if the measured value is between the limit values HIHI and LOLO.
• HI/LO collective alarm: The ALM_OUT_D output returns 1 if the measured value
corresponds to the HI limit value or overshoots this value if the measured value
corresponds to the LO limit value or undershoots this value. The output returns 0 if
the measured value is between the limit values HI and LO.
