Appendix C. FOUNDATION fieldbus Block Information
C.1 RESOURCE BLOCK
This section contains information on the Resource Block of the Rosemount
2230S Graphical Field Display.
The resource block defines the physical resources of the device. The
resource block also handles functionality that is common across multiple
blocks. The block has no linkable inputs or outputs.

Parameters
Index
Number Parameter Description
01 ST_REV The revision level of the static data associated with the function block.
02 TAG_DESC The user description of the intended application of the block.
03 STRATEGY The strategy field can be used to identify grouping of blocks.
04 ALERT_KEY The identification number of the plant unit.
05 MODE_BLK The actual, target, permitted, and normal modes of the block:
Target: The mode to “go to”
Actual: The mode the “block is currently in”
Permitted: Allowed modes that target may take on
Normal: Most common mode for actual
06 BLOCK_ERR This parameter reflects the error status associated with the hardware or software
components associated with a block. It is a bit string, so that multiple errors may be
shown.
07 RS_STATE State of the function block application state machine.
08 TEST_RW Read/write test parameter - used only for conformance testing.
09 DD_RESOURCE String identifying the tag of the resource which contains the Device Description for
this resource.
10 MANUFAC_ID Manufacturer identification number – used by an interface device to locate the DD file for
the resource.
11 DEV_TYPE Manufacturer’s model number associated with the resource - used by interface devices to
locate the DD file for the resource.
12 DEV_REV Manufacturer revision number associated with the resource - used by an interface device
to locate the DD file for the resource.
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
