23 NV_ CYCLE_T Minimum time interval specified by the manufacturer for writing copies of NV parameters to non-volatile
memory. Zero means it will never be automatically copied. At the end of NV_ CYCLE_T, only those
parameters which have changed need to be updated in NVRAM.
24 FREE_ SPACE Percent of memory available for further configuration. Zero in preconfigured resource.
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
will never happen when SHED_ RCAS = 0.
27 SHED_ ROUT Time duration at which to give up on computer writes to function block ROut locations. Shed from ROut will
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 FAULT_ STATE condition is set, then output function blocks will perform their FAULT_
STATE actions.
29 SET_ FSTATE Allows the FAULT_ STATE condition to be manually initiated by selecting Set.
30 CLR_ FSTATE Writing a Clear to this parameter will clear the device FAULT_ STATE 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 If set, no writes from anywhere are allowed, except to clear WRITE_ LOCK. Block inputs will continue to
be updated.
35 UPDATE_ EVT This alert is generated by any change to the static data.
36 BLOCK_ ALM The BLOCK_ ALM 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.
37 ALARM_ SUM The current alert 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 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 interoperability test case used in certifying this device as interoperable. The
format and range are controlled by the Fieldbus Foundation.
42 DISTRIBUTOR Reserved for use as distributor ID. No Foundation enumerations defined at this time.
43 DEV_STRING This is used to load new licensing into the device. The value can be written but will always read back with
a value of 0.
44 XD_ OPTIONS Indicates which transducer block licensing options are enabled.
45 FB_ OPTIONS Indicates which function block licensing options are enabled.
46 DIAG_ OPTIONS Indicates which diagnostics licensing options are enabled.
47 MISC_ OPTIONS Indicates which miscellaneous licensing options are enabled.
