Description

ACK_OPTION

23

0 = Auto Ack Disabled

None

0 all Disabled

Read and Write

Used to set auto acknowledgment of alarms.

 

 

1 = Auto Ack Enabled

 

 

 

 

ALARM_HYS

24

0 – 50

Percent

0.5

Read and Write

The amount the alarm value must return within

 

 

 

 

 

 

the alarm limit before the associated active alarm

 

 

 

 

 

 

condition clears.

ALM_SEL

38

HI_HI, HI, LO, LO_LO

None

Non selected

Read and Write

Used to select the process alarm conditions that

 

 

 

 

 

 

will cause the OUT_D parameter to be set.

ALARM_SUM

22

Enable/Disable

None

Enable

Read and Write

The summary alarm is used for all process

 

 

 

 

 

 

alarms in the block. The cause of the alert is

 

 

 

 

 

 

entered in the subcode field. The first alert to

 

 

 

 

 

 

become active will set the Active status in the

 

 

 

 

 

 

Status parameter. 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.

ALERT_KEY

04

1 – 255

None

0

Read and Write

The identification number of the plant unit. This

 

 

 

 

 

 

information may be used in the host for sorting

 

 

 

 

 

 

alarms, etc.

BLOCK_ALM

21

Not applicable

None

Not applicable

Read only

The block alarm is used for all configuration,

 

 

 

 

 

 

hardware, connection failure or system problems

 

 

 

 

 

 

in the block. The cause of the alert is entered in

 

 

 

 

 

 

the subcode field. The first alert to become active

 

 

 

 

 

 

will set the Active status in the Status parameter.

 

 

 

 

 

 

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.

BLOCK_ERR

06

Not applicable

None

Not applicable

Read only

This parameter reflects the error status

 

 

 

 

 

 

associated with the hardware or software

 

 

 

 

 

 

components associated with a block. It is a bit

 

 

 

 

 

 

string, so that multiple errors may be shown.

CAP_STDDEV

40

> = 0

Seconds

0

Read and Write

The time over which the VAR_INDEX is

 

 

 

 

 

 

evaluated.

CHANNEL

15

1 = Pressure

None

AI(1): Channel = 1

Read and Write

The CHANNEL value is used to select the

 

 

2 = Housing

 

AI2: Channel = 2

 

measurement value. Refer to the appropriate

 

 

temperature

 

 

 

device manual for information about the specific

 

 

 

 

 

 

channels available in each device.

 

 

 

 

 

 

You must configure the CHANNEL parameter

 

 

 

 

 

 

before you can configure the XD_SCALE

 

 

 

 

 

 

parameter.

FIELD_VAL

19

0 – 100

Percent

Not applicable

Read only

The value and status from the transducer block

 

 

 

 

 

 

or from the simulated input when simulation is

 

 

 

 

 

 

enabled.

GRANT_DENY

12

Program

None

Not applicable

Read and Write

Normally the operator has permission to write to

 

 

Tune

 

 

 

parameter values, but Program or Local remove

 

 

Alarm

 

 

 

that permission and give it to the host controller

 

 

Local

 

 

 

or a local control panel.

HI_ALM

34

Not applicable

None

Not applicable

Read only

The HI alarm data, which includes a value of the

 

 

 

 

 

 

alarm, a timestamp of occurrence and the state

 

 

 

 

 

 

of the alarm.

HI_HI_ALM

33

Not applicable

None

Not applicable

Read only

The HI HI alarm data, which includes a value of

 

 

 

 

 

 

the alarm, a timestamp of occurrence and the

 

 

 

 

 

 

state of the alarm.

HI_HI_LIM

26

Out_Scale(2)

Out_Scale(2)

Not applicable

Read and Write

The setting for the alarm limit used to detect the

 

 

 

 

 

 

HI HI alarm condition.

HI_HI_PRI

25

0 – 15

None

1

Read and Write

The priority of the HI HI alarm.

HI_LIM

28

Out_Scale(2)

Out_Scale(2)

Not applicable

Read and Write

The setting for the alarm limit used to detect the

 

 

 

 

 

 

HI alarm condition.

HI_PRI

27

0 – 15

None

1

Read and Write

The priority of the HI alarm.

IO_OPTS

13

Low Cutoff

None

Disable

Read and Write

Allows the selection of input/output options used

 

 

Enable/Disable

 

 

 

to alter the PV. Low cutoff enabled is the only

 

 

 

 

 

 

selectable option.

L_TYPE

16

Direct

None

Direct

Read and Write

Linearization type. Determines whether the field

 

 

Indirect

 

 

 

value is used directly (Direct), is converted

 

 

Indirect Square Root

 

 

 

linearly (Indirect), or is converted with the square

 

 

 

 

 

 

root (Indirect Square Root).
