Description
ACK_OPTION AUTO - MAN -
OOS
This parameter is used to specify whether a process alarm must be
acknowledged at the time of alarm detection by the fieldbus host
system. If this option is enabled the process alarm is
acknowledged automatically.
Options:
HI_HI_ALM
Upper limit value alarm
HI_ALM
Upper limit value warning
LO_LO_ALM
Lower limit value alarm
LO_ALM
Lower limit value warning
BLOCK ALM
Block alarm
Factory setting:
The option is not enabled for any alarm, the alarms must be
acknowledged.
ALARM_HYS AUTO - MAN -
OOS
Entry of the hysteresis value for the upper and lower warning or
alarm limit values. The alarm conditions remain active as long as
the measured value is within the hysteresis.
The hysteresis value affects the following warning and alarm limit
values of the Analog Input function block:
• HI_HI_ALM (upper limit value alarm)
• HI_ALM (lpper limit value warning)
• LO_LO_ALM (lower limit value alarm)
• LO_ALM (lower limit value warning)
User input:
0...50%
Factory setting:
0.5%
 Note!
The hysteresis value relates to a percentage of the range of the
OUT_SCALE parameter group in the Analog Input function block,
(see Page 178).
