Component Descriptions MicroLogix 1400 Memory Module and Built-in Real-Time Clock
The controller has a built-in real-time clock to provide a reference for
applications that need time-based control.
The controller is shipped with a memory module port cover in place. You can
order a memory module, 1766-MM1, as an accessory. The memory module
provides optional backup of your user program and data, and is a means to
transport your programs between controllers.
The program and data in your MicroLogix 1400 is non-volatile and is stored
when the power is lost to the controller. The memory module provides additional
backup that can be stored separately. The memory module does not increase the
available memory of the controller.
