HART 375 Communicator Application is not Opening


Thread Starter


Dear members & experts

HART application is not showing on display when entering into Hart application. I thought application is running back ground because when I press power ON/OFF button, it is showing a message "OFF key disabled, you must exit application". All other functions like display contrast, touch response, etc., are working normal. Flash card behind battery is removed and inserted back, but didn't get any solution. Please give possible solutions to get rid on this problem.
HART device is licensed for application only, not for upgradation.
waiting for your valuable suggestions, Thanks in advance.
