Figure 8-1. Input Selector Function
Block Schematic
BLOCK_ERR 06 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.
OUT 07 The block output value and status.
OUT_RANGE 08 High and low scale values, engineering units code, and number of digits to the right of the
decimal point associated with OUT
GRANT_DENY 09 Options for controlling access of host computers and local control panels to operating,
tuning, and alarm parameters of the block. Not used by device.
STATUS_OPTIONS 10 Allows you to select options for status handling and processing. The supported status
option for the integrator block is: “Use Uncertain as Good”, “Uncertain if Man mode.”
IN_1 11 The block input value and status.
IN_2 12 The block input value and status.
IN_3 13 The block input value and status.
IN_4 14 The block input value and status.
DISABLE_1 15 Parameter to switch off the input from being used 0- Use, 1 - Disable.
DISABLE_2 16 Parameter to switch off the input from being used 0- Use, 1 - Disable.
DISABLE_3 17 Parameter to switch off the input from being used 0- Use, 1 - Disable.
DISABLE_4 18 Parameter to switch off the input from being used 0- Use, 1 - Disable.
SELECT_TYPE 19 Determines the selector action; First good, Minimum, Maximum, Middle, Average.
MIN_GOOD 20 The minimum number of inputs which are “good” is less than the value of MIN_GOOD then
set the OUT status to “bad”.
SELECTED 21 The integer indicating the selected input number.
OP_SELECT 22 An operator settable parameter to force a given input to be used.
UPDATE_EVT 23 This alert is generated by any change to the static data.
BLOCK_ALM 24 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.
