ABNORM_ACTIVE
|
None
|
The indication that a block error condition not selected in BAD_MASK (on the function block level) is True (Active) or the indication that an error condition (at the module level) not selected in MERROR_MASK is True (Active) or a module status not selected in MSTATUS_MASK is True (Active).

ACK_OPTION
|
None
|
Enables or disables automatic acknowledgment of fieldbus device alarms. The default value is 0 (disabled). Set the value of this parameter to 65535 to enable the parameter before downloading the FFISELX block.
0 = disabled (the default)
65535 = enabled
|
ALARM_HYS

The amount the alarm value must return within the alarm limit before the associated active alarm condition clears. ALARM_HYS is limited to 50% of scale.
|
ALERT_KEY
|
None
|
A user-assigned identification number reported in alarm messages from the block that allows HMI applications to sort and filter alarms and events. Set this parameter for each function block to indicate the physical unit the function block is associated with. This information can be used in the host for sorting alarms, and so on.
|
ALM_SEL
|
None
|
Used to select the process alarm conditions that cause the OUT_D parameter to be True (Active).
|
AVG_USE
|
None
|
The minimum number of parameters the averaging calculation uses. An equal number of high and low values are dropped, leaving a number of values equal to or one greater than the value specified in AVG_USE.
Example 1: AVG_USE is 4 and the number of connected inputs is 6. The highest and lowest values are dropped before calculating the average.
Example 2: AVG_USE is 2 and the number of connected inputs is 7. The two highest and two lowest values are dropped and the average is calculated from the middle three inputs.
|
BAD_ACTIVE
|
None
|
The indication that a block error condition selected in BAD_MASK (at the function block level) is True (Active) or the indication that an error condition (at the module level) selected in MERROR_MASK is True (Active) or a module status selected in MSTATUS_MASK is True (Active).
|
BAD_MASK
|
None
|
The set of active error conditions that triggers a user-defined BAD condition. The user selects a subset of block error (BLOCK_ERR) conditions in the BAD_MASK parameter. When any of these conditions are True, the BAD_ACTIVE parameter becomes True. When any of the BLOCK_ERR conditions that are not included in BAD_MASK are True, ABNORM_ACTIVE becomes True.
|
BLOCK_ERR
|
None
|
The summary of active error conditions associated with the block.
|
DISABLE_n
where
n = 1 through 8
|
None
|
This parameter, when true, disables the corresponding input IN_n. A disabled input is not used by SELECT_TYPE configured algorithms.
|
HI_ACT
|
None
|
The result of alarm detection associated with HI_LIM. If HI_ACT equals True, HI_LIM has been exceeded.
|
HI_HI_ACT
|
None
|
The result of alarm detection associated with HI_HI_LIM. If HI_HI_ACT equals True, HI_HI_LIM has been exceeded.
|
HI_HI_LIM
|
EU of OUT_RANGE
|
The setting for the alarm limit used to detect the high high alarm condition.
|
HI_HI_PRI
|
None
|
To ensure proper operation, do not alter the default value unless instructed to do so by technical support.
|
HI_LIM
|
EU of OUT_RANGE
|
The setting for the alarm limit used to detect the high alarm condition.
|
HI_PRI
|
None
|
To ensure proper operation, do not alter the default value unless instructed to do so by technical support.
|
IN_n
where
n = 1 through 8
|
Determined by supplying block or source.
|
The analog input value and status corresponding to input number n.
|
LO_ACT
|
None
|
The result of alarm detection associated with LO_LIM. If LO_ACT equals True, LO_LIM has been exceeded.
|
LO_LIM
|
EU of OUT_RANGE
|
The setting for the alarm limit used to detect the low alarm condition.
|
LO_LO_ACT
|
None
|
The result of alarm detection associated with LO_LO_LIM. If LO_LO_ACT equals True, LO_LO_LIM has been exceeded.
|
LO_LO_LIM
|
EU of OUT_RANGE
|
The setting for the alarm limit used to detect the low low alarm condition.
|
LO_LO_PRI
|
None
|
To ensure proper operation, do not alter the default value unless instructed to do so by technical support.
|
LO_PRI
|
None
|
To ensure proper operation, do not alter the default value unless instructed to do so by technical support.
|
MIN_GOOD
|
None
|
Minimum number of usable inputs for the result to be not bad.
|
MODE
|
None
|
The mode record of the block. MODE contains the actual, target, permitted, and normal modes. In some function blocks, this parameter is used to request and show the source of the setpoint, the source of the output, and/or the block operating state.
|
OP_SELECT
|
None
|
Valid range is 0 through 8. If non-zero, selects the corresponding input (that is, 2 selects IN_2). If zero, the algorithm selected by SELECT_TYPE selects input.
|
OUT
|
EU of OUT_RANGE
|
The analog output value and status.
|
OUT_D
|
None
|
The discrete output value and status.
|
OUT_RANGE
|
None
|
The display scaling for the output (OUT). It has no effect on the block. You can set the high and low values, the engineering units, and the number of digits to the right of the decimal point.
|
SELECT_TYPE
|
None
|
If OP_SELECT is zero, determines the selection type. The following are valid selection types:
First Good
Minimum
Maximum
Middle
Average
Hot Backup
|
SELECTED
|
None
|
Output indicating the selected input or the number of usable inputs.
|
ST_REV
|
None
|
The revision level of the static data associated with the function block. To support tracking changes in static parameter fields, the associated block's static revision parameter is incremented each time a static parameter field value is changed. Also, the associated block's static revision parameter is incremented if a static parameter field is written but the value is not changed.
|
STATUS_OPTS
|
None
|
Status options allow you to select options for status handling and processing. The options available are:
|
STRATEGY
|
None
|
Used to identify groupings of blocks. This data is not checked or processed by the block.
