Write Valid Range Description
45 8045 8145 ALARM_SUM Enable The current alert status,
unacknowledged states, unreported
states, and disabled states of the
alarms associated with the function
block.
46 8046 8146 ACK_OPTION 0xFFFF Selection of whether alarms associated
with the block will be automatically
acknowledged.
47 8047 8147 ALARM_HYS 0.5% 0 to 50% Hysteresis for alarm detection and
resetting to prevent each alarm from
occurring and recovering repeatedly
within a short time.
48 8048 8148 HI_HI_PRI 0 0 to 15 Priority order of HI_HI_ALM alarm.
49 8049 8149 HI_HI_LIM +INF PV_SCALE Setting for HI_HI_ALM alarm.
50 8050 8150 HI_PRI 0 0 to 15 Priority order of HI_ALM alarm.
51 8051 8151 HI_LIM +INF PV_SCALE Setting for HI_ALM alarm.
52 8052 8152 LO_PRI 0 0 to 15 Priority order of LO_ALM alarm.
53 8053 8153 LO_LIM -INF PV_SCALE Setting for LO_ALM alarm.
54 8054 8154 LO_LO_PRI 0 0 to 15 Priority order of LO_LO_ALM alarm.
55 8055 8155 LO_LO_LIM -INF PV_SCALE Setting for LO_LO_ALM alarm.
56 8056 8156 DV_HI_PRI 0 0 to 15 Priority order of DV_HI_ALM alarm.
57 8057 8157 DV_HI_LIM +INF Setting for DV_HI_ALM alarm.
58 8058 8158 DV_LO_PRI 0 0 to 15 Priority order of DV_LO_ALM alarm.
59 8059 8159 DV_LO_LIM -INF Setting for DV_LO_ALM alarm.
60 8060 8160 HI_HI_ALM — — Alarm that is generated when the PV
value has exceeded the HI_HI_LIM
value and whose priority order* is
defined in HI_HI_PRI.
* Priority order: Only one alarm is
generated at a time.
When two or more alarms occur at
the same time, the alarm having the
highest priority order is generated.
When the PV value has decreased
below [HI_HI_LIM - ALM_HYS],
HI_HI_ALM is reset.
61 8061 8161 HI_ALM — — As above
62 8062 8162 LO_ALM — — As above
Reset when the PV value has
increased above
[LO_LIM + ALM_HYS].
63 8063 8163 LO_LO_ALM — — As above
64 8064 8164 DV_HI_ALM — — Alarm that is generated when the
value of [PV - SP] has exceeded the
DV_HI_LIM value. Other features are
the same as HI_HI_ALM.
65 8065 8165 DV_LO_ALM — — Alarm that is generated when the value
of [PV - SP] has decreased below the
DV_LO_LIM value. Other features are
the same as LO_LO_ALM.
