7 4007 4107 4207 4307 PV — — Either the primary analog value for use in
executing the function, or a process value
associated with it. May also be calculated
from the READBACK value of an AO block.
8 4008 4108 4208 4308 OUT — Value =
Man
The primary analog value calculated as a
result of executing the function.
9 4009 4109 4209 4309 SIMULATE Disable Auto Allows the transducer analog input or
output to the block to be manually supplied
when simulate is enabled. When simulation
is disabled, the simulate value and status
track the actual value and status.
10 4010 4110 4210 4310 XD_SCALE Specified at
the time of
order
O/S The high and low scale values, engineering
units code, and number of digits to the right
of the decimal point used with the value
obtained from the transducer for a specified
channel. Refer to Table A1.5 for the unit
available.
11 4011 4111 4211 4311 OUT_SCALE 0 - 100 % O/S The high and low scale values, engineering
units code, and number of digits to the right
of the decimal point to be used in displaying
the OUT parameter and parameters which
have the same scaling as OUT.
12 4012 4112 4212 4312 GRANT_
DENY
0 Auto Options for controlling access of host
computers and local control panels to
operating, tuning and alarm parameters of
the block.
13 4013 4113 4213 4313 IO_OPTS 0 O/S Options which the user may select to alter
input and output block processing.
14 4014 4114 4214 4314 STATUS_
OPTS
0 O/S Options which the user may select in the
block processing of status.
15 4015 4115 4215 4315 CHANNEL AI1: 1
AI2: 2
AI3,AI4: 3
O/S The number of the logical hardware
channel that is connected to this I/O block.
This information defines the transducer to
be used going to or from the physical world.
16 4016 4116 4216 4316 L_TYPE Specified at
the time of
order
Man Determines if the values passed by the
transducer block to the AI block may be
used directly (Direct) or if the value is in
different units and must be converted
linearly (Indirect), or with square root (Ind
Sqr Root), using the input range defined by
the transducer and the associated output
range.
17 4017 4117 4217 4317 LOW_CUT 0% Auto Limit used in square root processing. A
value of zero percent of scale is used in
block processing if the transducer value
falls below this limit, in % of scale. This
feature may be used to eliminate noise
near zero for a flow sensor.
18 4018 4118 4218 4318 PV_FTIME 0sec Auto Time constant of a single exponential filter
for the PV, in seconds.
19 4019 4119 4219 4319 FIELD_VAL — — Raw value of the field device in percent
of thePV range, with a status reflecting
the Transducer condition, before signal
characterization (L_TYPE) or filtering
(PV_FTIME).
