Overview

BMX RMS ••••• memory cards are used to save projects, Web pages, and data in general.

They are mainly used when inserted into a PLC. They may also be read with an SD-card drive or reader.

Memory Card in the PLC

When the memory card is in the Modicon M340, it may be accessed as follows:

• with the PLC, automatically

• with the Control Expert commands PLC > Project Backup... > ....

• by programming with the Memory Card File Management EFBs (See Memory Card File Management in the System library)

• with an FTP client (for processors with an Ethernet connection) to manage files on the memory card

Memory Card in an SD-card Drive or Reader

When the memory card is inserted into an SD-card drive or reader, it may be accessed as a data storage medium (for example, a USB key or hard drive). The files on the memory card may thus be viewed.

Tree Structure of Files on the Memory Card

When the memory card is used in an SD-card drive or reader, or via FTP, its contents are accessible with a file explorer. The tree structure shown includes three directories:

• DataStorage, which includes all data files from Memory Card File Management EFBs

• Firmware, which includes all files used by the Automation Device Maintenance software

• Web, which includes all Web pages

It is also possible to create directories for personal files.
