Idx Parameter Description / Range / Selections / Note
BLOCK_OBJ
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
STRATEGY The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
ALERT_KEY The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
MODE_BLK
TARGET AUTO / MAN / OOS The selectable modes by the operator.
ACTUAL The mode the block is currently in.
PERMITTED AUTO / MAN / OOS Allowed modes that the target may take on
NORMAL AUTO The common mode for the Actual.
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.
TOTAL_SP Set Point for a batch UP totalization. When the OUT reaches it, the OUT is
reset and the N_RESET is incremented.
OUT
This variable is the most significant part of the
internal Total (Total = net increment added
every cycle regardless of status). The OUT value
is expressed in OUT_RANGE Unit.
Writeable only if MODE_BLK.ACTUAL = MAN
OUT_RANGE
The high and low scale values, engineering units code, and number of digits to the right of the decimal point used only for
displaying of the totals (OUT, STOTAL, RTOTAL SRTOTAL) by a host. The high and low range values of OUT_RANGE have no
effect on the block
GRANT_DENY
STATUS_OPTS
Options which the user can select for the block processing of status. The available selections are:
Uncertain if MAN Mode
the input is set to Accumulate it is expressed in number of pulses.
the input is set to Accumulate it is expressed in number of pulses.
OUT_TRIP
OFF
The first discrete output. Set to ON when the TOTAL_SP is reached. This
value is set to ON when OUT ≥ TOTAL_SP in UP totalization or OUT ≤
DOWN totalization. When a reset occurs, OUT_TRIP is no longer true, so it
RESET_CONFIRM is not connected or if the INTEG_OPTS is not set to
Confirm Reset.
ON
OUT_PTRIP
OFF
The second discrete output. This value is set to ON when OUT ≥ (TOTAL_
SP - PRE_TRIP) in UP totalization or OUT ≤ PRE_TRIP in DOWN totalization.
When a reset occurs, OUT_PTRIP is no longer true, so it is cleared.
ON
