Yes, they are both counted.
Example: CP1 PV = 10, CP2 PV = 5
Simultaneous input of CP1 and CP2 results in CP1 CV = 11 and CP2 PV = 6.
The dual count value after addition is CP1 PV + CP2 PV, therefore 11 + 6 = 17.
Example: CP1 PV = 10, CP2 PV = 5
Simultaneous input of CP1 and CP2 results in CP1 CV = 11 and CP2 PV = 6.
The dual count value after subtraction is CP1 PV - CP2 PV, therefore 11 - 6 = 5.
