Controller channels
Number
Controller type
Controller structure
Controller outputs
Disturbance feedforward con-
trol
Autotuning
Sampling rate
a
Ena. variable disturbance permits consideration of influencing variables in the process
environment beyond the actual value alone. This keeps the control response stable, even when
fluctuations in such ambient conditions occur.
20.15.2
Recording function
a
Number of groups
Number of input variables per
group
Recording /
Memory rate
Memory values
Size of the ring buffer
d
History function
Archiving/evaluation
a
A freely configurable set of input variables can be pooled in one group.
Each group has its own display screen. The group affiliation is considered for data storage to enable eval-
uation via PC.
b
The measurement data are stored in a ring buffer. When the ring buffer is full, the recording
function starts to overwrite the measured-value history at the beginning of the ring buffer.
c
This information is based on 4 analog values and 3 binary values, and is provided for orientation.
The total is for both groups.
