STRATEGY
Used to identify groupings of blocks. Not used by the block itself.
TAG_DESC (Diagnostic)
User description for the purpose of the block.
TEST_RW (Process)
Unused by the block algorithm. Used to test interoperability of reads and
writes of different parameter types.
TRK_IN_D (Scaling)
Used to enable tracking of the output value to TRK_VAL . When this is true,
the output value of the block takes on the value specified in TRK_VAL .
TRK_SCALE (Scaling)
The scaling parameter used for the value specified by TRK_VAL .
TRK_VAL (Scaling)
The value the block will track when tracking is enabled by TRK_IN_D .
UPDATE_EVT (Diagnostic)
The current state of the update event, along with a time and date stamp. This
event is issued whenever a static parameter is changed and
ST_REV is
incremented. The index information for the parameter that changed and the
new value of
ST_REV is included in the alert.
WRITE_ALM (Alarming)
State of the alert generated if WRITE_LOCK is cleared, along with a time and
date stamp.
WRITE_LOCK (Option)
The software write lock for the device. When this is set to true, writes to all
configuration parameters of all blocks are disallowed. The
WRITE_ALM
block alarm is active when writes are allowed and clear when they are
disallowed.
