Don't compromise the functionality of your processes by not implementing security settings on your GE PLCs. Security can be set to four different levels of access on your PLC. If a user types in the password for a particular level, then they have the ability to do different tasks.

You can get to this screen by right clicking the online target and choosing Online Commands - Show status and then click the Protection tab.

Once the passwords are assigned, you then have to enable passwords in the hardware configuration.

Changing this will require a STOP download. Once this is complete you will have different levels of access available.
