6.3 I/O Actual Data Presentation
6.3.1 Digital and Analog I/O
At the end of the actual data branch, the digital I/O actual state screen and, if set, the analog I/O state
screen can be listed.
The digital I/O actual data screen shows actual state of all of the inputs and outputs :
•
… off-state (or inactive : the input voltage below defined threshold or open output)
•
… on-state (or active : the input voltage over defined threshold or closed output)
If a digital input frequency counter processing is set, its name (
Vwind
on the example) and actual
value (
8.21 m/s
) is shown in appropriate line too. Otherwise, a dash is displayed only.
If any of analog quantities processing is set too, the analog I/O actual data screen is shown in the
branch (otherwise, it is skipped) :
The analog input represented quantity value corresponds to actual input current or voltage at
appropriate analog input according to the set ratio. At the example, the represented quantity
Vflow
has
actual value of 19
.27 m
