button release issue (use one button to trigger several other buttons)

[bhl3302]

Hi All, previously I have a question about using a button to trigger several buttons(use one "read all" button to trigger several "read" buttons). According to one referred code, we can use an event and a "read all" button to assign the true to several "read" button.But when I press "read all", all the buttons are assisgned as "True", and they are fixed as true instead of being released. Here is the comparison of normal button operation and my current situation. Could anyone advise how to solve this? Thank you!

To use the "Val(Sgnl)" property of a button, the Mechanical Action of the button has to be "Switch". It sounds like you are more used to the "Latch" mechanical action, that automatically sets the button back to false after it has been read. The fix is to set the buttons false yourself after you have detected they are true -- see the picture below:
