What does the time value of 12 seconds in the box mean?
Or logic: as long as any one of the conditions in the upper ‘or’ part is met, it is combined with the ‘and’ operation in the lower part; if all conditions are satisfied, then the step is activated. It can be understood as being executed in parallel or synchronously.
In other words, once all the above conditions are met, the process proceeds after a 12-second delay. Here, TW is used; what does TA mean?
Oh, TW refers to the situation where the time wait condition is met and waiting occurs, while TA means that the time alarm has exceeded the set time, triggering an alarm signal
