AI1 AI2 AI3
10 4010 4110 4210 XD_SCALE Specifi ed at the
time of order
(Note 3) (-40 to
260°C for AI2,
0 to 10m
3 /h for
AI3)
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 specifi ed channel. Refer to Section 6.3 "AI Function
Block Parameters" for the unit available.
11 4011 4111 4211 OUT_SCALE Specifi ed at the
time of order
(Note 3) (-40 to
260°C for AI2,
0 to 10m
3 /h for
AI3)
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.
Refer to Section 6.3 "AI Function Block Parameters" for
the unit available.
12 4012 4112 4212 GRANT_DENY 0x00 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 IO_OPTS 0x0000 (AI1)
0x0000 (AI2)
0x0000 (AI3) O/S Options which the user may select to alter input and
output block processing. bit 6: Low cutoff
14 4014 4114 4214 STATUS_OPTS 0 O/S Options which the user may select in the block
processing of status. bit 3: Propagate Failure Forward,
bit 6: Uncertain if Man mode, bit 7: Bad if limited, bit 8:
Uncertain if Man mode.
15 4015 4115 4215 CHANNEL 1 (AI1)
2 (AI2)
5 (AI3) O/S The number of the logical hardware channel that is
connected to this I/O block. This information defi nes
the transducer to be used going to or from the physical
world. AI1: Flow rate, AI2: Temperature, AI3: Volumetric
fl ow rate.
16 4016 4116 4216 L_TYPE Direct (1) MAN Determines if the values passed by the transducer
block to the AI block may be used directly (Direct (1)) or
if the value is in different units and must be converted
linearly (Indirect (2)), or with square root (Ind Sqr Root
(3)), using the input range defi ned by the transducer
and the associated output range. "Indirect Square
Root" is not used for the digitalYEWFLO.
17 4017 4117 4217 LOW_CUT 0.0 (AI1)
0.0 (AI2)
0.0 (AI3) AUTO Sets low cut point of output. This low cut value become
available by setting "Low cutoff" to "IO-OPTS".
18 4018 4118 4218 PV_FTIME 0sec (AI1)
0sec (AI2)
0sec (AI3) AUTO Time constant of a single exponential fi lter for the PV,
in seconds.
19 4019 4119 4219 FIELD_VAL — — Raw value of the fi eld device in percent of the PV
range, with a status refl ecting the Transducer condition,
before signal characterization (L_TYPE), fi ltering (PV_
FTIME), or low cut (LOW_CUT).
20 4020 4120 4220 UPDATE_EVT — — This alert is generated by any change to the static data.
21 4021 4121 4221 BLOCK_ALM — — The block alarm is used for all confi guration, hardware,
connection failure or system problems in the block. The
cause of the alert is entered in the subcode fi eld. The
fi rst 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 ALARM_SUM — — The current alert status, unacknowledged states,
unreported states, and disabled states of the alarms
associated with the function block.
23 4023 4123 4223 ACK_OPTION 0xffff AUTO Selection of whether alarms associated with the block
will be automatically acknowledged.
24 4024 4124 4224 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. 0 to 50
25 4025 4125 4225 HI_HI_PRI 0 AUTO Priority of the high high alarm. 0, 1, 3 to 15
26 4026 4126 4226 HI_HI_LIM 1. #INF AUTO The setting for high high alarm in engineering units.
(Note 1)
27 4027 4127 4227 HI_PRI 0 AUTO Priority of the high alarm. 0, 1, 3 to 15
