Rosemount 2230
Appendix C. FOUNDATION fieldbus Block Information
17 FEATURES Used to show supported resource block options.
The supported features are:
• HARD_WRITE_LOCK_SUPPORT
• SOFT_WRITE_LOCK_SUPPORT
• REPORT_SUPPORT
• UNICODE_SUPPORT
• MULTI_BIT ALARM
• FAULT_STATE_SUPPORT
18 FEATURES_SEL Used to select resource block options.
19 CYCLE_TYPE Identifies the block execution methods available for this resource.
20 CYCLE_SEL Used to select the block execution method for this resource. The Rosemount 2230
supports the following:
Scheduled: Blocks are only executed based on the function block schedule.
Block Execution: A block may be executed by linking to another blocks completion.
21 MIN_CYCLE_T Time duration of the shortest cycle interval of which the resource is capable.
22 MEMORY_SIZE Available configuration memory in the empty resource. To be checked before
attempting a download.
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 a pre-configured device.
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.
