Sd Memory Card - Mitsubishi Electric MELSEC iQ-R Series User Manual

SD memory card

This memory is used to store the folder/file created by a function using the SD memory card as well as the user's folder/file.
The folder configuration is the same as the data memory. However, in the case of the SD memory card, the "$MELPRJ$"
folder will be created when the SD memory card becomes available (when the SD memory card is mounted).
For details on how to insert or remove the SD memory card, refer to the following.

How to forcibly disable the SD memory card with a special relay
If the SD memory card is removed while the CPU module is powered on, data in the SD memory card may be corrupted.
Use a special relay to forcibly disable access to the SD memory card without turning off the power.
The following shows how to forcibly disable the SD memory card with a special relay.
1.
Turn on SM606 (SD memory card forced disable instruction). After an instruction by SM606, and until SM607 changes,
an instruction by the ON/OFF state change of SM606 is disabled. Note that after SM607 changes, an instruction by the
ON/OFF state change of SM606 is enabled, and operation is performed based on the ON/OFF state of SM606.
