There are several options for configuring the MicroLogix 1100 that can be very useful.
- Double-click on the Controller Properties item in the project tree and then select the Passwords tab.
If we want to protect the program, we can assign a password. We can also assign a Master Password so that we can protect each PLC with a different password but assign a Master Password for use by a lead engineer or supervisor. Be careful! If you forget the password, it cannot be recovered and access to the program will be lost.
- Double-click on Processor Status, we can view status information for many facets of the MicroLogix CPU.
- On the Processor tab, we can view information about the CPU model and firmware revisions.

Select Search in the main menu and then select Find if you want to search for where an address is used or select Replace if you want to replace one address with another...
