Chapter 6 Using Real-Time Clock and Memory Modules

Removal/Insertion Under Power

The memory module can be installed or removed without risk of damage to

either the memory module or the controller, except during a data transaction. If

the memory module is removed during a data transaction, data corruption can

occur.

If a memory module is installed while the MicroLogix 1400 is executing, the

memory module is not recognized until either a power cycle occurs, or until the

controller is placed in a non-executing mode (program mode, suspend mode or

fault condition).

Memory Module Information File

The controller has a Memory Module Information (MMI) File which provides

status from the attached memory module. At power-up or on detection of a

memory module being inserted, the catalog number, series, revision, and type are

identified and written to the MMI file. If a memory module is not attached, zeros

are written to the MMI file. Refer to the MicroLogix 1400 Instruction Set

Reference Manual, publication 1766-RM001

, for more information.

Program /Data Download

To download the program and data from a memory module to the controller’s

memory, on the “Comms” menu in your RSLogix 500/RSLogix Micro

programming software, point “EEPROM” and then click “Load from

EEPROM”.

Program /Data Upload

To upload the program and data from the controller’s memory to a memory

module, on the “Comms” menu in your RSLogix 500/RSLogix Micro

programming software, point “EEPROM” and then click “Store to EEPROM”.

TIP

With MicroLogix 1400, you can also use the LCD and the LCD buttons

on the module to transfer applications to or from the controller.

For more information on program/data download, refer to your

RSLogix 500/RSLogix Micro programming software documentation.
