Chapter 25 Memory Card Mode
25-2
The memory card mode has two major functions: memory manager and data
logging.
Memory Manager Function
SRAMs or CF cards can be used as external storage media for the PLC. Data
can be written or read out at any time required. The memory card emulation
area of an SRAM or a CF card is divided into a maximum of 16 files. Each file is
divided into a maximum of 4095 records. Data is stored in each record.
It is possible to store records in a block from the PLC into an SRAM area or a CF
card, or to read them from an SRAM area or a CF card to the PLC. Since a
large capacity of data can be stored, it is not necessary to allocate memory in
the PLC for storage purpose.
