7.1 Using the IC Memory Card
Using the Card to Expand the Data Memory Area
Data written to data registers and other destinations is written to the IC memory card.
When the card is used in this way, the IC memory card can be used as an expanded
memory area that lets data be written and read using the sequence program.
Data is written using the F13 (ICWT) instruction of the sequence program, and is read
from the IC memory card using the F12 (ICRD) instruction.
The FROM type of card can only be used for reading data.
