Complete Resource Block Parameter Listing (cont’d)
SHED REMOTE OUT
Time duration at which to give up on computer writes to function block Rout locations. Shed from
Rout shall never happen when SHED REMOTE OUT = 0.
FAULT_STATE Condition set by loss of communication to an output block, fault promoted to an output block or a
physical contact. When Fault State condition is set, then output function blocks will perform their
FSTATE actions.
SET FAULT STATE
Allows the Fault State condition to be manually initiated by selecting Set.
CLEAR FAULT STATE
Writing a Clear to this parameter will clear the device fault state if the field condition, if any, has
cleared.
MAXIMUM NOTIFY
Maximum number of unconfirmed alert notify message possible.
LIMIT NOTIFY
Maximum number of unconfirmed alert notify messages allowed.
CONFIRM_TIME
The time the resource will wait for confirmation of receipt of a report before trying again. Retry shall
not happen when CONFIRM_TIME = 0.
WRITE_LOCK
If set, no writes from anywhere are allowed, except to clear WRITE_LOCK. Block inputs will
continue to be updated.
UPDATE_EVT
This alert is generated by any change to the static data.
BLOCK_ALM 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 attribute. 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.
