The 1764-MM1 is a MicroLogix 1500 compatible memory module. This memory module is mainly used to provide memory backup, practical data transfer from one controller to another and data recovery during controller’s fault condition. This memory module has an Electrically Erasable Programmable Read Only Memory (EEPROM) memory type and does not require a backup battery to retain the moduel’s contents. the memory contents are retained without the need of a battery.
The 1764-MM1 compares with an compact and portable assembly with integrated memory amounting to 8 Kilo Bytes. This memory module permits saving of user program, perform Data Back-Up, perform Program Compare, implement Data File Download Protection and Memory Module Write Protection. This module supports Removal and Insertion Under Power (RIUP) however, a power cycle may be needed to allow the processor to recognize the installed memory module.
