BMXRMS004GPF SD Memory Card

The SD memory card is an option that can be used for application and data storage. The SD memory card slot in the M580 CPU housing is behind a door.

Use a BMXRMS004GPF memory card in your CPU. It is a 4 GB, Class 6 card rated for industrial use. Other memory cards, including those used in M340 CPUs, are not compatible with M580 CPUs.

NOTE: If you insert an incompatible SD memory card in the CPU:

  • The CPU remains in NOCONF state.

  • The CPU BACKUP LED turns ON.

  • The memory card access LED remains blinking.

BMXRMS004GPF SD Memory Card Format

The BMXRMS004GPF memory card is formatted specifically for the M580 CPUs.

  • If you use this card with another CPU or tool, the card may not be recognized.

  • If you re-format the card in another device – e.g., a camera – the card becomes incompatible for use by an M580 CPU. In this case, you need to return the card to Schneider Electric for re-formatting.

Memory Card Characteristics

These memory card characteristics apply to M580 CPUs:

Characteristic

Value

global memory size

4 GB

application backup size

200 MB

data storage size

3.8 GB

write/erase cycles (typical)

100,000

operating temperature range

–40...+85 °C (–40...+185 °F)

file retention time

10 years

memory zone for FTP access

data storage directory only
NOTE: Due to formatting, wearout, and other internal mechanisms, the actual available capacity of the memory card is slightly lower than its global size.

Supported Functions

The SD memory card supports read-only data storage functions.

NOTE: In addition to these read-only data storage functions, you can also read and write to the SD memory card using the following Control Expert project management commands located in the PLC > Project Backup menu:

  • Backup Compare

  • Backup Restore

  • Backup Save

Formatting the Memory Card is Unnecessary

The SD memory card comes pre-formatted from the factory. There is no need to manually format the SD memory card using your PC. If you attempt to format the SD memory card, you may alter the formatted structure of the card, thereby rendering the card unusable.
