Write Valid Range Description
32 RCAS_IN 0 Remote setpoint set from a computer, etc.
33 ROUT_IN 0 Remote control output value set from a
computer, etc.
34 SHED_OPT 0 Action to be performed in the event of mode
shedding. SHED_OPT defines the changes
to be made to MODE.BLK.target and MODE.
BLK.actual when the value of RCAS_IN.status
or ROUT_IN.status becomes Bad if .MODE_
BLK.actual = RCas or ROut. See Section
A4.17.1 for details.
35 RCAS_OUT 0 — Remote setpoint sent to a computer, etc.
36 ROUT_OUT 0 — Remote control output value
37 TRK_SCALE 100
0
1342
1
MAN Upper and lower scale limits used to convert
the output tracking value (TRK_VAL) to non-
dimensional.
38 TRK_IN_D 0 Switch for output tracking. See Section A4.12
for details.
39 TRK_VAL 0 Output tracking value (TRK_VAL) When
MODE_BLK.actual = LO, the value scaled
from the TRK_VAL value is set in OUT.
40 FF_VAL 0 Feedforward input value.
The FF_VAL value is scaled to a value with
the same scale as for OUT, multiplied by the
FF_GAIN value, and then added to the output
of the PID computation.
41 FF_SCALE 100
0
1342
1
MAN Scale limits used for converting the FF_VAL
value to a non-dimensional value.
42 FF_GAIN 0 MAN Gain for FF_VAL
43 UPDATE_EVT — Same as that for an AI block.
44 BLOCK_ALM — Same as that for an AI block.
45 ALARM_SUM Enable Same as that for an AI block.
46 ACK_OPTION 0xffff Same as that for an AI block.
47 ALARM_HYS 0.5% 0 to 50% Hysteresis for alarm detection and resetting
to prevent each alarm from occurring and
recovering repeatedly within a short time.
48 HI_HI_PRI 0 0 to 15 Priority order of HI_HI_ALM alarm
49 HI_HI_LIM +INF PV_SCALE Setting for HI_HI_ALM alarm
50 HI_PRI 0 0 to 15 Priority order of HI_ALM alarm
51 HI_LIM +INF PV_SCALE Setting for HI_ALM alarm
52 LO_PRI 0 0 to 15 Priority order of LO_ALM alarm
53 LO_LIM -INF PV_SCALE Setting for LO_ALM alarm
54 LO_LO_PRI 0 0 to 15 Priority order of LO_LO_ALM alarm
55 LO_LO_LIM -INF PV_SCALE Setting for LO_LO_ALM alarm
56 DV_HI_PRI 0 0 to 15 Priority order of DV_HI_ALM alarm
57 DV_HI_LIM +INF Setting for DV_HI_ALM alarm
58 DV_LO_PRI 0 0 to 15 Priority order of DV_LO_ALM alarm
59 DV_LO_LIM -INF Setting for DV_LO_ALM alarm
60 HI_HI_ALM — — Alarm that is generated when the PV value
has exceeded the HI_HI_LIM value and
whose priority order* is defined in HI_HI_PRI.
* Priority order: Only one alarm is generated
at a time. When two or more alarms occur
at the same time, the alarm having the
highest priority order is generated. When
the PV value has decreased below [HI_HI_
LIM -ALM_HYS], HI_HI_ALM is reset.
