4.1.1. Target Mode (PROFIBUS PA only)
Used to request an operating mode from the Function Block.
4.1.2. Unit
Engineering unit to be displayed with the output value.
4.1.3. Filter Time Constant
The time constant for the damping filter. The engineering unit is always in
seconds. (This is an exponential filter: when a change occurs at the input, the
output will be at 63.2% of the change in one time constant, and will be at full
change after 5 time constants.)
4.1.4. Function
Used to select between the different level block outputs: Level, or Distance. (See
on page 100 for an illustration.)
4.1.5. Batch Information (PROFIBUS PA only)
These 4 parameters are intended to be used in Batch Applications conforming to
IEC 61512 Part 1 (ISA S88). Other applications do not require these values, which
are only stored in the Function Block.
4.1.5.1. Batch ID.
Identifies a certain batch to allow assignment of equipment-
related information (for example faults, alarms) to the batch.
4.1.5.2. Batch Unit
Identifies the active Control Recipe Unit Procedure or the related Unit (for
example, reactor, centrifuge, drier).
4.1.5.3. Batch operation
Identifies the active Control Recipe Operation.
4.1.5.4. Batch Phase
Identifies the active Control Recipe Phase.
