Description
Data Type: DS-82
Allows the analog input to be manually supplied
when simulate is enabled. When simulation is
disabled, the simulate value and status track
actual value & status.
Data Type: DS-68
The high and low scale values, engineering units
code, and number of decimal places to be used in
displaying the PV parameter and parameters
which have the same scaling as PV.
Data Type: DS-68
The high and low scale values and engineering
units code are read only. This parameter
determines the number of digits to the right of the
decimal point used with the value obtained from
the transducer for a specified channel.
Data Type: DS-70
Options for controlling access of host computers
and local control panels to operating, tuning, and
alarm parameters of the block.
GRANT: 1 = granted, 0= N/A
DENY: 1 = denied, 0 = N/A
Data Type: Bit String (2 byte)
0=disable
1=enable
Allows you to select the type of tracking and the
output value when a fault condition occurs.
Data Type: Bit String
0=disable
1=enable
Options the user may select for the block
processing of status.
Data Type: DS-65
Readback is the de-characterized valve position
as reported by the transducer block parameter
FINAL_POSITION_VALUE [17]. This correlates
with the AO block parameter OUT [9], which is
the setpoint to the transducer. READBACK is the
simulated input if SIMULATE is enabled or the
transducer block feedback if SIMULATE is
disabled.
Data Type: DS-65
The setpoint value from another function block.
