BMXRMS004GPF SD Memory Card

The BMXRMS004GPF memory card is a 4 GB, Class 6 card rated for industrial use. The SD memory card slot resides behind the door on the front of the CPU.

You can use a BMXRMS004GPF memory card for application and data storage.

You can use a BMXRMS004GPF memory card for storage of:

  • The M580 safety project application.

  • Data for the non-safe tasks (MAST, FAST, AUX0, AUX1).

NOTE:

  • Data cannot be stored on the SD memory card for the SAFE task.

  • The SD memory card is not included in the safety loop.

You can insert and extract the card while power is ON and the PAC is in RUN mode. However, to avoid data losses, use system bit %S65 to make a system request to stop data access to the card before extracting it from the CPU.

NOTE: Other memory cards, including those used in M340 CPUs, are not compatible with M580 CPUs. 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.

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.
