I have situation where I use one HSC input for two measurement.

For example:

Bit M0.0 high - My process is activated

Bit M0.1 high - need to count pulses for 1st measurement when process is active

Bit M0.2 high - need to count pulses for 2nd measurement when process is active

Bits M0.1 and M0.2 are never active at same time but changes ON and OFF all the time. While my process is activated I need to count accumulated pulses for 1st and 2nd measurement.

Can someone give me guidance how to do this with the best way ...

Tnx in advance for any help

HSC is counting flow ... I have one flowmeter and 2 valves (M0.1 opens 1st and M0.2 opens 2nd valve) ... Valves are never open together ...
In one cycle of measurement (M0.0 high) I need to count flow through each of 2 pipes controlled by this 2 valves.
