Table C-1. Resource Block Parameters

Number Parameter Description

23NV_ 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.
48	RB_ SFTWR_	Major revision of software that the resource block was created with.
	REV_ MAJOR
49	RB_ SFTWR_	Minor revision of software that the resource block was created with.
	REV_ MINOR
50	RB_ SFTWR_	Build of software that the resource block was created with.
	REV_ BUILD
51	RB_SFTWR_REV_	The string contains the following fields:
	ALL	Major rev: 1-3 characters, decimal number 0-255
		Minor rev: 1-3 characters, decimal number 0-255
		Build rev: 1-3 characters, decimal number 0-255
		Time of build: 8 characters, xx:xx:xx, military time
		Day of week of build: 3 characters, Sun, Mon,
		Month of build: 3 characters, Jan, Feb.
		Day of month of build: 1-2 characters, decimal number 1-31
		Year of build: 4 characters, decimal
		Builder: 7 characters, login name of builder
52	HARDWARE_ REV	Hardware revision of that hardware that has the resource block in it.
