I have a 1756-L73 controller hooked to a C-More T15CL HMI. On one of the screens, there is a momentary push button to activate a process.This button was hung in the “pushed” condition and verified by the bit in theprogram.
I thought there might be a bad place on the screen, so Imoved the button to a different location to check. Upon reloading, the button remainedin the “pushed” condition. I then went into the program and toggled the bitassociated with this pushbutton. Everything cleared so I returned the HMI screento its original condition. Operation was normal after several test cycles.
Assuming my issue was in the HMI to begin with, what causesa pushbutton to hang up on a screen? (Side note: This push button also has a 2second delay before going true.)
I guess if this problem re-occurs, I will swap out the HMI.Is there a fail-safe method to prevent this from happening?
What would Space-X do if this happened on their rocket touchscreen?
Thanks,
