Options for controlling access of host computers and local
control panels to operating, tuning and alarm parameters of
the block.
-
GRANT
Grant
R/W Depending on the philosophy of the plant, the operator or a
higher level device (HLD) or a local operator's panel (LOP) in
the case of "Local", may turn on an item of the "Grant"
attribute - "Program, Tune, Alarm or Local".
Uninitialized
Setting:
Program / Tune / Alarm / Local / Operate
DENY
Deny
R/W The denied attribute is provided for use by a monitoring
application in an interface device and may not be changed by
an operator.
Uninitialized
Setting:
Program denied / Tune denied / Alarm denied / Local denied /
Operate denied

Settings of 5 subelements for previous 2 parameters High Alarm and High High Alarm:
UNACKNOWLEDGED
Unacknowledged
R/W A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.
Uninitialized
Setting:
Uninitialized / Acknowledged / Unacknowledged
ALARM_STATE
Alarm State
R A discrete enumeration which gives an indication of whether
the alert is active and whether it has been reported.
Uninitialized
Setting:
Uninitialized / Clear - reported / Clear - not reported / Active -
reported / Active - not reported
TIME_STAMP
Time Stamp
R The time when evaluation of the block was started and a
change in alarm/event state was detected that is unreported.
The time stamp value will be maintained constant until alert
confirmation has been received - even if another change of
state occurs.
Uninitialized
Setting:
MM / DD / YY (Month / Day / Year)
HH:MM:SS (Hour:Minute:Second)
SUB_CODE
Subcode
R An enumeration specifying the cause of the alert to be
reported.
Other
Setting:
Other / Block Configuration / Link Configuration / Simulation
Active / Local Override / Device Fault State / Device
Maintenance / Input Failure / Output Failure / Memory
Failure / Lost Static Data / Lost NV Data / Readback Check /
Maintenance Needed / Power Up / Out Of Service
VALUE

R A numerical quantity entered by a user or calculated by the
algorithm.
