Figure 192:
Periodic reporting
Amplitude dead-band supervision
If a measuring value is changed, compared to the last reported value, and the change
is larger than the ±ΔY pre-defined limits that are set by user (
UDbRepIn
), then the
measuring channel reports the new value to a higher level. This limits the information
flow to a minimum necessary. Figure
shows an example with the amplitude dead-
band supervision. The picture is simplified: the process is not continuous but the
values are evaluated with a time interval of one execution cycle from each other.
