B.1 Block configuration
B.1.1 Resource block
The resource block defines the physical resources of the device including type of measurement,
memory, etc. The resource block also defines functionality, such as shed times, that is common across
multiple blocks. The block has no linkable inputs or outputs and it performs memory-level diagnostics.
Table B-1. Resource Block Parameters
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. For further description, see
the Mode parameter formal model in FF-890.
06 BLOCK_ERR This parameter reflects the error status associated with the hardware or software
components associated with a block. Multiple errors may be shown. For a list of enumeration
values, see FF-890, Block_Err formal model.
07 RS_STATE State of the function block application state machine. For a list of enumeration values, see
FF-890.
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 the
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 the interface device to locate the
DD file for the resource.
14 GRANT_DENY Options for controlling access of host computer and local control panels to operating, tuning
and alarm parameters of the block.
15 HARD_TYPES The types of hardware available as channel numbers. The supported hardware type is:
SCALAR_INPUT
16 RESTART Allows a manual restart to be initiated.
1. Run: This is passive state of this parameter.
2. Restart resource: To clear up the problems like garbage collection.
3. Restart with defaults: reset all configurable function block application objects to their
initial value i.e. their value before any configuration was done by the user. This will also
remove appended serial numbers of function block tags
4. Restart processor: provides a way to hit the reset button on the processor associated with
the resource.
5. Restart to append serial number: Appends serial number to function block tags.
11. Restart default blocks: defaults manufacturer pre-instantiated blocks.
