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.
