21 4021 4121 4221 4321 BLOCK_ALM — — The block alarm is used for all
configuration, hardware, connection failure
or system problems in the block. The cause
of the alert is entered in the subcode field.
The first alert to become active will set the
Active status in the Status attribute. As
soon as the Unreported status is cleared by
the alert reporting task, another block alert
may be reported without clearing the Active
status, if the subcode has changed.
22 4022 4122 4222 4322 ALARM_
SUM
Enable — The current alert status, unacknowledged
states, unreported states, and disabled
states of the alarms associated with the
function block.
23 4023 4123 4223 4323 ACK_
OPTION
0xfff : unack Auto Selection of whether alarms associated
with the block will be automatically
acknowledged.
24 4024 4124 4224 4324 ALARM_HYS 0.5% Auto Amount the PV must return within the alarm
limits before the alarm condition clears.
Alarm Hysteresis is expressed as a percent
of the PV span.
25 4025 4125 4225 4325 HI_HI_PRI 0 Auto Priority of the high high alarm.
26 4026 4126 4226 4326 HI_HI_LIM +INF Auto The setting for high high alarm in
engineering units.
27 4027 4127 4227 4327 HI_PRI 0 Auto Priority of the high alarm.
28 4028 4128 4228 4328 HI_LIM +INF Auto The setting for high alarm in engineering
units.
29 4029 4129 4229 4329 LO_PRI 0 Auto Priority of the low alarm.
30 4030 4130 4230 4330 LO_LIM –INF Auto The setting for the low alarm in engineering
units.
31 4031 4131 4231 4331 LO_LO_PRI 0 Auto Priority of the low low alarm.
32 4032 4132 4232 4332 LO_LO_LIM –INF Auto The setting of the low low alarm in
engineering units.
33 4033 4133 4233 4333 HI_HI_ALM — — The status for high high alarm and its
associated time stamp.
34 4034 4134 4234 4334 HI_ALM — — The status for high alarm and its associated
time stamp.
35 4035 4135 4235 4335 LO_ALM — — The status of the low alarm and its
associated time stamp.
36 4036 4136 4236 4336 LO_LO_ALM — — The status of the low low alarm and its

HEADER
Block tag
= O/S
Information about this block, including the
block tag, DD revision, execution time. The
value for “Period of Execution” should be
larger than “Execution Time.”
1 6001 6101 6201 6301 ST_REV 0 — Incremented when a change is made to
the parameter settings for the DI block to
indicate the revision level of the settings,
and used to see whether there is a change
in parameter settings.
2 6002 6102 6202 6302 TAG_DESC Spaces Universal parameter storing the
description of the tag.
3 6003 6103 6203 6303 STRATEGY 1 Universal parameter used by an upper-
level system to classify the function blocks.
