SLC 500 Programmable Controllers and I/O Modules
Memory Modules
The following table summarizes the available memory back up options for the SLC 500 processors. EEPROM memory modules provide
non-volatile memory back-up. Flash EPROMs (Flash Erasable Programmable Read Only Memory) combine the versatility of EEPROMs with
the security of UVPROMs.

Program Storage Device
The 1747-PSD Program Storage Device simplifies PLC program backup and upgrade shipping issues for MicroLogix controllers and SLC
5/03 and higher processors. It allows you to backup PLC programs without using a computer or programming software. The PSD also
enables you to make multiple copies of an installed program. OEMs can confidently ship program upgrades to end users for easy and
low-cost installation at remote sites.
Features
• The 1747-PSD provides reliable storage of user programs. The device is designed for repetitive use; upload and download as you
need to. It performs error checking prior to downloading a PLC program to ensure that the program is compatible with the target PLC.
• The PSD can be powered by either two AAA batteries or by an external power supply. A battery save feature shuts off power
30 seconds after the operation is completed. Stored programs are retained in Flash EPROM memory even if the batteries and
power supply fail.
• The hand-held device is lightweight and very easy to use. Only minimal training should be needed. One red LED and one green LED
provide instant status feedback. For ease of operation, all of the PSD functions can be accessed using one switch and one push button.
• Installation of the PSD is simple, using a standard RS-232, 9-pin, D-shell connector. The device attaches to the PLC with standard
SLC 500 and MicroLogix cables.
• For maximum compatibility, the 1747-PSD can store the largest PLC programs of the SLC 500 and MicroLogix programmable controllers.
