Write Description
8 5008 SP 0 Auto Indicates the setpoint for the block.
9 5009 OUT 0 Man Indicates the output value and its status.
10 5010 SIMULATE disable Used to simulate the output from the Transducer
block; allows the user to set the value and status
input from the specied channel.
11 5011 PV_SCALE 0-100% O/S High and low scale values when displaying the
PV parameter and the parameters which have the
same scaling as PV.
12 5012 XD_SCALE 0-100% O/S High and low scale values used with the value
obtained from or sent to the transducer block for a
specied channel.
13 5013 GRANT_DENY 0 Option to control access from the host computer
and local control panel to tuning and alarm
parameters.
14 5014 IO_OPTS 0x000A O/S Settings for the I/O processing of the block
15 5015 STATUS_OPTS 0x0000 O/S Denes block actions depending on block status
conditions.
16 5016 READBACK — — Readback signal of valve position from transducer
block
17 5017 CAS_IN — Cascade input.
18 5018 SP_RATE_DN +INF Rate-of-decrease limit for SP effective in AUTO,
CAS, and RCAS modes. If this parameter is 0, no
limit is applied to the rate of decrease.
19 5019 SP_RATE_UP +INF Rate-of-increase limit for SP effective in AUTO,
CAS, and RCAS modes. If this parameter is 0, no
limit is applied to the rate of increase.
20 5020 SP_HI_LIM 100 Upper limit for setpoint (SP)
21 5021 SP_LO_LIM 0 Lower limit for setpoint (SP)
22 5022 CHANNEL 1 O/S Denes the channel number of the hardware
channel connected to the transducer block.
Always set to 1 for the AO block in a YVP110.
23 5023 FSTATE_TIME 0 second Denes the time from when the fault state of
the RCAS_IN or CAS_IN is detected to when
the output should be set to the level preset in
FSTATE_VAL (this action takes place only if Fault
State to value is set as true in I/O_OPTS).
24 5024 FSTATE_VAL 0 Preset output level for fault state. See above.
25 5025 BKCAL_OUT — — Value to be input to BKCAL_IN of the downstream
block; used by the downstream block to prevent
reset windup and perform bumpless transfer to
closed-loop control.
26 5026 RCAS_IN —
Remote cascade setpoint set by the host
computer, etc.
27 5027 SHED_OPT 1 Denes the mode shedding action to be taken
upon occurrence of time-out of communication in
a mode using the remote setpoint.
28 5028 RCAS_OUT — — Remote setpoint sent to a host computer, etc.
29 5029 UPDATE_EVT — — Shows the contents of an update event upon
occurrence.
30 5030 BLOCK_ALM — — Shows the contents of a block alarm upon
occurrence.
