Description / Range / Selections / Notes
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
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.
The user description of the intended application of the block
The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
AUTO / MAN / OOS
AUTO / MAN / OOS
AUTO / CAS
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.
The block output value calculated as a result of the block
execution, expressed in OUT_RANGE unit code
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 scaling for the output. It has no effect on the block
Options for controlling access of host computer and local control panels to operating, tuning and alarm parameters
of the block.
Options the user may select to alter the calculation done in a control loop

This alert is generated by any change to the static data
The block alarm is used for all configuration, hardware, connection failure or system problems in the block.
The cause of the alert is entered in the subcode field. The first alert to become active will set the Active Status in the
status parameter. As soon as the Unreported status is cleared by the alert reporting task, another block alert may be
reported without clearing the Active Status, if the subcode has changed.
The selectable modes by the operator.
The mode the block is currently in.
Allowed modes that the target may take on
The common mode for the Actual.
Writeable only if MODE_BLK .ACTUAL = MAN
Enable/Disable the propagation of the Status byte from
the PRTB in input at the AI to its Output
Parameter to switch off the input 1 from being used
Parameter to switch off the input 2 from being used
Parameter to switch off the input 3 from being used
Parameter to switch off the input 4 from being used
If the number of inputs which are good is less than the
value of MIN_GOOD then set the out status to bad.
An integer indicating which input has been selected
An operator settable parameter to force a given input to
be used
