Initial Value Explanation
0 16 BLOCK_OBJECT RO — Information on this block such as Block Tag, DD
Revision, Execution Time etc.
1 17 ST_REV RO 0 The revision level of the static data associated
with the function block. The revision value will be
incremented each time a static parameter value in
the block is changed
2 18 TAG_DESC AUTO Blank The user description of the intended application of
the block.
3 19 STRATEGY AUTO 0 The strategy field can be used to identify grouping
of blocks.
This data is not checked or processed by the block
4 20 ALERT_KEY AUTO 0 The identification number of the plant unit. This
information may be used in the host for sorting
alarms, etc.
5 21 TARGET_MODE AUTO AUTO Set the Target of block mode (MODE_BLK) to
Auto or O/S according to the write Mode of the
parameter to be set or changed.
The permitted bit is only available.
6 22 MODE_BLK RO AUTO,
AUTO | O/S,
AUTO
The mode parameter is a structured parameter
composed of the actual mode, the normal mode,
and the permitted mode
