About 1764-MM3

The 1764-MM3 is a passive component of the MicroLogix family used to increase the memory of the controller. It specifically functions as a non-volatile memory that saves project files and stores them even if power is removed. The 1764-MM3 basically has no difference with the 1764-MM2. Both have 16KB memory. Only exceptions is that the 1764-MM3 can store data from the Data Log Queue area. The MicroLogix 1500 LSP/LRP OS FRN 11 or later can support full functionality of the 1764-MM3. The memory operation can be configured using the RSLogix500 software. Status of the 1764-MM3 can be observed with the status bits S:1/10, S:1/11, S:1/12. Specifically, user can trigger the S:1/11 “Load Memory Module Always” to automatically load the user program in the memory card everytime the controller is power cycled. The user program is first downloaded into a processor’s memory and is then stored to the back-up memory module from the processor. To store the program to EEPROM in RSLogix500, Go online with the MicroLogix controller that has the EEPROM for burning. Change the controller on REM-PROG mode. Select Comms--> EEPROM--> Store to EEPROM. The MicroLogix controller burns the EEPROM. If Store/Load to EEPROM is not highlighted, there is no memory module installed in the controller or connection is not established or offline. It is best to store a spare memory aside from the one installed in the CPU. This provides redundancy in situations that the active installed memory card gets corrupted. The backup memory card contents may differ slightly than the one installed, ensure at least that the commissioned program including the basic configuration is kept inside the backup memory card.
