pid control in producer/consumer mode ?

Hello guys,

Could i use pid control in producer/consumer mode ?

Now in our lab, we use pid control the fuel pressure in producer/consumer mode.

I put the data acquisition in the producer loop and the pid control in consumer mode.

I found there will be delay between the value acquired in the producer loop and the value sent to pid.

Is  that because there are delay between the producer/consumer ?

Thanks.
