Parameter Description
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.
Options for controlling access of host computers and local control panels to
operating, tuning, and alarm parameters of the block. Not used by device.
The types of hardware available as channel numbers.
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
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
Used to select resource block options.
Identifies the block execution methods available for this resource.
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.
Time duration of the shortest cycle interval of which the resource is capable.
Available configuration memory in the empty resource. To be checked before
attempting a download.
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.
Percent of memory available for further configuration. Zero in a pre-configured
device.
Percent of the block processing time that is free to process additional blocks.
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
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
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.
Allows the FAIL_SAFE condition to be manually initiated by selecting Set.
