By selecting "Virtual"
you can enter a sub-area where it’s possible to create virtual channels; some
"Virtual Cards" are available to be considered as groups of channels
of definable number without limit.
Input channels are used to
simulate dynamic acquisitions.
The output channels are used as
variables or as temporary allocations of memory in which to write the numeric
values to be used in other moments or portions of the program.
Typical uses:
- Storage of intermediate states, for example partial ratings, with which
then do a calculation or a final assessment
- storing values in different times for evaluations of differences or
trends
As all
logical channels of "output" type, their value can be changed:
- by action or profile (i.e. automation)
- by connecting to another logical channel
