string indicator is not proplerly updating boolean action

[Anil@8899]

Hello there,

in the below VI i am trying to send different CAN messages using boolean,

problem is if i want to send the different messages i am not receiving the response for the current sent message, instead i am receiving the response for previously sent message ,but if i press boolean for 3-4 times i am receiving the current update. 

could anyone please guide me .

I can't open your code, but the description is 99.7% a Race Condition.

The VI has dependencies that you didn't include so can't run it, and the problem might exist in those dependencies anyway.

But I will say that if your Boolean is False, then your loop is gonna run at a million miles an hour and it's gonna hog CPU resources.

Hi Anil,

If you want to Execute True state on demand, you can better prefer Event based State Machine Architecture, In  that case all Local Variable and  Race Conditions can be avoided.

Please use Event based state machine architecture and shift register to hold string data.
