25 FREE_TIME Percent of the block processing time that is free to process
additional blocks.
26 SHED_RCAS Time duration at which to give up on computer writes to function
block RCas locations. Shed from RCas shall never happen when
SHED_ROUT = 0
27 SHED_ROUT Time duration at which to give up on computer writes to function
block ROut locations. Shed from ROut shall never happen when
SHED_ROUT = 0
28 FAULT_STATE Condition set by loss of communication to an output block, fault
promoted to an output block or physical contact. When FAIL_SAFE
condition is set, then output function blocks will perform their
FAIL_SAFE actions.
29 SET_FSTATE Allows the FAIL_SAFE condition to be manually initiated by
selecting Set.
30 CLR_FSTATE Writing a Clear to this parameter will clear the device FAIL_SAFE if
the field condition has cleared.
31 MAX_NOTIFY Maximum number of unconfirmed notify messages possible.
32 LIM_NOTIFY Maximum number of unconfirmed alert notify messages allowed.
33 CONFIRM_TIME The time the resource will wait for confirmation of receipt of a
report before trying again. Retry will not happen when
CONFIRM_TIME=0.
34 WRITE_LOCK When hardware write protection is selected, WRITE_LOCK
becomes an indicator of the jumper setting and is unavailable for
software write protection.
When software write lock is selected, and WRITE_LOCK is set, no
writings from anywhere else are allowed, except to clear
WRITE_LOCK. Block input will continue to be updated.
35 UPDATE_EVT This alert is generated by any change to the static data.
36 BLOCK_ALM The block alarm is used for all configuration, hardware, connection
failure or system problems in the block. The cause of the alarm is
entered in the subcode field. The first alarm to become active will
set the Active status in the Status parameter. As soon as the
Unreported status is cleared by the alarm reporting task, another
block alarm may be reported without clearing the Active status, if
the subcode has changed.
37 ALARM_SUM The current alarm status, unacknowledged states, unreported
states, and disabled states of the alarms associated with the
function block.
38 ACK_OPTION Selection of whether alarms associated with the function block will
be automatically acknowledged.
39 WRITE_PRI Priority of the alarm generated by clearing the write lock.
40 WRITE_ALM This alert is generated if the write lock parameter is cleared.
41 ITK_VER Major revision number of the inter operability test case used in
certifying this device as interoperable. The format and range are
controlled by the Fieldbus Foundation.
42 FD_VER A parameter equal to the value of the major version of the Field
Diagnostics specification that this device was designed to.
