13 DD_REV Revision of the DD associated with the resource - used by an interface device to
locate the DD file for the resource. The DD_REV specifies the minimum DD revision
that is compatible with the device (within the same device revision). A vendor can
release an updated DD with the DD_REVISION higher than the DD_REV. This allows
a vendor to release an updated DD files set that will be compatible with an existing
device revision in the field. The host can always load a higher DD_REVISION for a
given DEV_REV/DEV_REVISION.
As per Foundation requirement the DD_REV will always be 01.
14 GRANT_DENY Options for controlling access of host computers and local control panels to
operating, tuning, and alarm parameters of the block. Not used by device.
15 HARD_TYPES The types of hardware available as channel numbers.
16 RESTART Allows a manual restart to be initiated. Several degrees of restart are possible. They
are the following:
1 Run – is the passive state of the parameter
2 Restart resource – not used
3 Restart with defaults – intended to reset parameters to default values, i.e. their
value before any configuration was done
4 Restart processor – does a warm start of CPU
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.
