In the Block Object data structure, there are different items describing the block characteristics. Execution period, Number
of parameters in the block, the DD Revision, Profile Revision, View Objects characteristics and so on
ST_REV
The revision level of the Static data associated with the Function Block. The revision level is incremented each time a static
parameter value (S – under Storage) in the block is changed.
TAG_DESC The user description of the intended application of the block

is a bit string, so that multiple errors may be shown.
OUT The block output value calculated as a result of the
block execution, expressed in OUT_SCALE unit
Writeable only if MODE_BLK.ACTUAL = MAN
OUT_SCALE
The high and low scale values, engineering units code, and number of digits to the right of the decimal point to be used in
displaying the OUT parameter and parameters which have the same scaling as OUT.

BKCAL_IN
The analog input value from another block’s BKCAL_OUT output that is used to prevent reset windup and to initialize the
control loop. Expressed in OUT_SCALE Unit
OUT_HI_LIM
Expressed in OUT_SCALE Unit
Limits the maximum output value.
OUT_LO_LIM Limits the minimum output value.
UPDATE_ EVT This alert is generated by any change to the static data
BLOCK_ALM
The block alarm is used for all configuration, hardware, connection failure or system problems in the block. The cause of the
