hi, i searched this, found some related topics but i still couldn't solve my problem. actually i don't really need a real parallel programming. i just have simple test procedure and have an i/o card communicating via serial port. i prepared the communication vi, i can read inputs and write to output pins of the io device. but in the whole program, i have put some waits about 5-45 seconds.when the program executes the wait(ms) command, my io module vi does not work so my communication with the module breaks off. so i can not sense the changing inputs during this time. how can i communicate via rs232 and run my test sequence simultanously?or is there a timing method that does not stop the sequence? i am not very familiar with labview, but when programming PLCs, the timers does not stop the execution of thecommands after them. the cyclic operation continues, when the preset time elapses, the timer gives a contact. may be if there is a similar method, it can be helpful for me. thanks.

Hi tonay,

you didn't say so before... Just move the user button&led either into the wait loop or in their own parallel running loop!
