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 Level Transducer Block function groups 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.
