Combining digital channels:
• setting up only required if digital channels are to be combined with each other.
Examples: Sums of impulse counters, logical combination of digital channels
etc.
Selection of how two or more digital channels can be combined with each other
"Addition/subtraction": For impulse counters.
"Sum/averages": Of impulse counters or operational time counters.
"Logical combination: For on/off events.
Hint: Only the channels that could be combined can be selected. All combinations
are handled in the same way as real signals, this means that they are updated every
second, can be monitored for alarm set point infringements and be allocated to
groups etc.
Description of the combination. Cannot be changed (for information only).
Selection if impulse counters or operation time counters are to be combined. Only
possible when "Sum/average value" are to be created.
Expansion (or description of the combination created in this channel).
Selection if the average or sum is to be calculated from channels "y1" to "y2". Only
possible when "Sum/average value" are to be created.
Input 'y1', that is to be combined with another input.
Hint: Other combinations can also be used so long as their number is smaller than the
actual combination. So e.g. combination 1 can be used in combination 2
("Cascading").
