Using Tag BIT Value for calculation

[derguang]

Hi

I wants to know that if Tag BIT value can consider as the integer of '1' or '0'?

And I wants do some multiplication as follow:

Globals.Tags.ch1State.Value = (Globals.Tags.Application_CH1ST.Value*2)+Globals.Tags.Application_CH1AL.Value*3)+Globals.Tags.Application_CH1MD.Value*5);

the xxxState.Value is to use for multipicture display.
