Parameters
2.3.1.4. Filter Time Constant
The time constant for the damping filter. The damping filter smooths out the
response to a sudden change in level. This is an exponential filter and the
engineering unit is always in seconds (see Damping on page 117
for more
detail
).
2.3.1.5. Channel
Used to select between the different Level Transducer Block outputs.
2.3.1.6. Batch Information
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 Analog Input Function Block.
2.3.1.6.1. Batch ID
Identifies a certain batch to allow assignment of equipment-related
information (for example faults, alarms) to the batch.
2.3.1.6.2. Batch Unit
Identifies the active Control Recipe Unit Procedure or the related Unit
(for example, reactor, centrifuge, drier).
2.3.1.6.3. Batch operation
Identifies the active Control Recipe Operation.
2.3.1.6.4. Batch Phase
Identifies the active Control Recipe Phase.
