Write Description
33 8033 ROUT_IN — Remote control output value set from a computer, etc.
34 8034 SHED_OPT 1 Defines the mode shedding actions, namely, the
changes to be made to MODE.BLK.target and MODE.
BLK.actual when (1) the value of RCAS_IN.status
becomes Bad if MODE_BLK.actual = RCAS, or when (2)
the value of ROUT_IN.status becomes Bad if MODE_
BLK.actual = ROUT.
35 8035 RCAS_OUT — — Remote setpoint sent to a host computer, etc.
36 8036 ROUT_OUT — — Remote control output value
37 8037 TRK_SCALE 0-100% Man Upper and lower scale limits used to convert the output
tracking value (TRK_VAL) to non-dimensional.
38 8038 TRK_IN_D Switch for output tracking
39 8039 TRK_VAL Output tracking value. When MODE_BLK.actual = LO,
the value scaled from the TRK_VAL value is set in OUT.
40 8040 FF_VAL Feed-forward 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 8041 FF_SCALE 0-100% Man Scale limits used for converting the FF_VAL value to a
non-dimensional value
42 8042 FF_GAIN 0 Man Gain for FF_VAL
43 8043 UPDATE_
EVT
— — Shows the contents of an update event upon
occurrence.
44 8044 BLOCK_ALM — — Shows the contents of a block alarm upon occurrence.
45 8045 ALARM_SUM Enable Shows the alarm summary (current alarm statuses,
acknowledged/unacknowledged states, masking states)
46 8046 ACK_OPTION 0xFFFF Selects whether or not the alarms related to the DI block
are automatically self-acknowledged.
47 8047 ALARM_HYS 0.5% Hysteresis for alarm detection and resetting to prevent
each alarm from occurring and recovering repeatedly
within a short time
48 8048 HI_HI_PRI 0 Priority order of HI_HI_ALM alarm
49 8049 HI_HI_LIM +INF Setting for HI_HI_ALM alarm
50 8050 HI_PRI 0 Priority order of HI_ALM alarm
51 8051 HI_LIM +INF Setting for HI_ALM alarm
52 8052 LO_PRI 0 Priority order of LO_ALM alarm
53 8053 LO_LIM +INF Setting for LO_ALM alarm
54 8054 LO_LO_PRI 0 Priority order of LO_LO_ALM alarm
55 8055 LO_LO_LIM +INF Setting for LO_LO_ALM alarm
56 8056 DV_HI_PRI 0 Priority order of DV_HI_ALM alarm
57 8057 DV_HI_LIM +INF Setting for DV_HI_ALM alarm
58 8058 DV_LO_PRI 0 Priority order of DV_LO_ALM alarm
59 8059 DV_LO_LIM +INF Setting for DV_LO_ALM alarm
60 8060 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.
61 8061 HI_ALM — — As above
62 8062 LO_ALM — — As above Reset when the PV value has increased above
[LO_LIM + ALM_HYS].
63 8063 LO_LO_ALM — — As above
64 8064 DV_HI_ALM — — An alarm that is generated when the value of [PV - SP]
has exceeded the DV_HI_LIM value. Other features are
the same as HI_HI_ALM.
65 8065 DV_LO_ALM — — Alarm that is generated when the value of [PV - SP] has
decreased below the DV_LO_LIM value. Other features
are the same as LO_LO_ALM.
