Control variables for totalizers 1–3 (output data)
These functions allow totalizers 1–3 to be controlled from the automation system.
The following controls are possible: totalizing, resetting, activation of a predefined value,
balancing, totalisation of positive flow only, totalisation of negative flow only and
stopping of totalizing.
Data transfer from the automation system to Prosonic Flow 93 (totalizer controls)
!
Note!
A control variable can be executed through the cyclic data exchange each time the
output byte changes from one bit pattern to any other bit pattern.
It is only possible to preset a predefined totalizer value via the local operation or the
Class 2 master!
