The following communication objects are used to control the "Differential counting” function:
A Count
B Count
No. | Object name | Function | Datapoint type | Flags |
|---|---|---|---|---|
41 44 | A Count B Count | Set value | 6.010 counter pulses (-128..127) 8.001 pulses difference 13.001 counter pulses (signed) | CW |
Function:
The counter status for the counter of channel A can be set via the communication object "A Count."
Due to the difference of “counter B minus counter A,” in practical terms this is the counter for the people leaving the room or zone.
The counter status for the counter of channel B can be set via the communication object "B Count."
Due to the difference of “counter B minus counter A", in practical terms this is the counter for the people entering the room or zone.

A Start value
B Start value
No. | Object name | Function | Datapoint type | Flags |
|---|---|---|---|---|
43 46 | A Start value B Start value | Set value | 6.010 counter pulses (-128..127) 8.001 pulses difference 13.001 counter pulses (signed) | CRW |
Function:
Via the communication object "A Start value” the starting value of the counter of channel A is set.
The starting value of the counter of channel B is set via the communication object "B Start value."
Based on these two determinations of the counter readings, the first difference at the beginning of the counting process is determined.
Availability:
The "A Start value” and "B Start value” communication objects are displayed if the following configurations have been made:
- Parameter "Function channels A + B” on the "device settings” parameter card
- Setting: “Pairwise”
- Parameter "Function channels” on the “functions, objects” parameter card
- Setting: “Differential counting”
