Problem after setting password to a button

[nail9394 0]

I have a NS screen connecting to cj2 plc through Ethernet  that is working fine, I need  to password protect one of the screen push button so I set up a level 2 password to that pushbutton. After I up load the modified program to the NS all integer readout blanks out and screen button is not functioning, I switch back to the original screen program and it is working good again, will somebody help me to figure out why it happens or it need a certain procedure to add password protection to an existing project.  Thanks in advance

If all buttons are not working you probably change something with the communication settings that is not communicating with PLC.

I did not touch anything other than adding a password......

I had a similar issue before. I did modified the HMI program and didn't change anything with the communication but somehow it was trying to communicate thru Serial Port which was set as Ethernet/IP.  I did go into admin mode after dumping the program and in communication settings assigned the serial ports as not used.
