Temperature Multi-Input Device
Function Block Descriptions
15 CHANNEL The CHANNEL value is the number of the physical
input (transducer output) that is used as input for the
function block. Supported values are:
■
1-8: physical input from Channel 1 to Channel 8
■
10: physical input from concentrator block that is
the internal device temperature
16 L_TYPE Determines in which of the following ways the field
value is used:
■
Directly (Direct)
■
Linearly converted (Indirect)
■
Converted with the square root (Indirect Square
Root)
17 LOW_CUT % If transducer input percentage value falls below this
value, then PV is set to 0
18
PV_FTIME Seconds Time constant of the first-order filter for the PV. It is
the time required for a 63 % change in the PV or OUT
value. Used for filtering the response time.
19
FIELD_VAL % The value (in percent of the PV range) and status
from the transducer block or from the simulated input
before signal characterization.
20
UPDATE_EVT This alert is generated by any change to the static
data.
21 BLOCK_ALM Block alarm 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 ALARM_STATE subcode. 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.
22 ALARM_SUM The current alert status, unacknowledged states, and
disabled states of the alarm associated with the
function block.
23 ACK_OPTION Used to set auto acknowledgement of alarms.
24
ALARM_HYS % Span (in percent of the PV span) in which a PV must
return before an alarm condition is cleared.
25 HI_HI_PRI The priority of the HI-HI alarm.
26
HI_HI_LIM EU of PV_SCALE The setting for the alarm limit used to detect the HI-HI
alarm condition.
27 HI_PRI The priority of the HI alarm.
28
HI_LIM EU of PV_SCALE The setting for the alarm limit used to detect the HI
alarm condition.
29 LO_PRI The priority of the LO alarm.
30
LO_LIM EU of PV_SCALE The setting for the alarm limit used to detect the LO
alarm condition.
31 LO_LO_PRI The priority of the LO-LO alarm.
32
LO_LO_LIM LO_LO_PRI The setting for the alarm limit used to detect the LO-
LO alarm condition.
33 HI_HI_ALM HI-HI alarm data including a value of the alarm, a time
stamp of occurrence, and the state of the alarm.
34
HI_ALM HI alarm data including a value of the alarm, a time
stamp of occurrence, and the state of the alarm.
35 LO_ALM LO alarm data including a value of the alarm, a time
stamp of occurrence, and the state of the alarm.
