Access Description and settings
R/W The feed forward input high and low scale values, engineering
units code and number of digits to the right of the decimal
point.
R/W The engineering unit value which represents the upper end of
range of the associated block parameter.
R/W The engineering unit value which represents the lower end of
range of the associated block parameter.
R/W Device Description units code index for the engineering unit
descriptor for the associated block value.
Setting:
All units are possible.
R The feed forward value and status.
R Status of FF_VAL
R Value of FF_VAL
R/W Dimensionless value used by the block algorithm in
calculating the block output.
R/W Options for controlling access of host computers and local
control panels to operating, tuning and alarm parameters of
the block.
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, Tuning, Alarm or Local.
Setting:
•
Program: Host may change mode, setpoint or output of block
•
Tune: Host may change the tuning parameters of block
•
Alarm: Host may change the alarm parameters of block
•
Local: A local panel or handheld device may change the
target mode, setpoint or output
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.
Setting:
•
Program denied: Granting of program permission has been
reset
•
Tune denied: Granting of tune permission has been reset
•
Alarm denied: Granting of alarm permission has been reset
•
Local denied: Granting of local permission has been reset
Mix The status for High Alarm and its associated time stamp.
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.
Setting:
Uninitialized / Acknowledged / Unacknowledged
