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
