Table 3-2. Resource Block Parameters

Number

Parameter

Description

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

If set, all writes to static and non-volatile parameters are prohibited, 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_REV_MAJOR

Major revision of software that the resource block was created with.

49

RB_SFTWR_REV_MINOR

Minor revision of software that the resource block was created with.

50

RB_SFTWR_REV_BUILD

Build of software that the resource block was created with.

51

RB_SFTWR_REV_ALL

The string will contains the following fields:

 

 

Major rev: 1-3 characters, decimal number 0-255

 

 

Minor rev: 1-3 characters, decimal number 0-255

 

 

Build rev: 1-5 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.

53

OUTPUT_BOARD_SN

Output board serial number.

54

FINAL_ASSY_NUM

The same final assembly number placed on the label.

55

DETAILED_STATUS

Indicates the state of the transmitter. NOTE: Will be writable when PWA_SIMULATE is On

 

 

during simulation mode.

56

SUMMARY_STATUS

An enumerated value of repair analysis.

57

MESSAGE_DATE

Date associated with the MESSAGE_TEXT parameter

58

MESSAGE_TEXT

Used to indicate changes made by the user to the device’s installation, configuration, or

 

 

calibration.

59

SELF_TEST

Used to self test the device. Tests are device specific.
