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 specified 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

specified 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

Defines 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

Defines 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

Defines 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

Defines 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.
