*1 A drive number is used to specify memory where data are written or read by external devices using a sequence program or
MC protocol. Since memory names are used to specify memory using a programming tool, drive numbers do not need to be
considered.
*2 Store the intelligent function module parameters in the same drive with the parameters. The intelligent function module
parameters stored in a different drive are not valid.
*3 A program stored in the standard ROM cannot be executed. Store the program to the program memory before
execution.
*4 To execute a program stored in a memory card or SD memory card, make the setting in the Boot file tab of the PLC
parameter dialog box.
*5 The device comments cannot be read by instructions in a sequence program.
*6 Several scans are required to read device comments using a sequence program.
*7 CPU modules other than the High-speed Universal model QCPU and Universal model Process CPU store only one file
for each item. The High-speed Universal model QCPU and Universal model Process CPU store more than one file for
each item.
*8 For the number of storable file register points, refer to Page 390, Section 4.7.
*9 A sequence program allows reading only. No data can be written from the sequence program.
*10 Data can be written or read with the following instructions.
•
SP.FREAD (batch-reads data from the specified file in the memory card.)
•
SP.FWRITE (batch-writes data to the specified file in the memory card.)
*11 This is the data in which the information of label program configuration is stored.

*12 CPU modules other than the High-speed Universal model QCPU and Universal model Process CPU: The file name and
extension will be SRCINF1M.CAB or SRCINF2M.CAB for Simple projects (with a label), and SRCINF1I.CAB or
SRCINF2I.CAB for Structured projects.
High-speed Universal model QCPU and Universal model Process CPU: The file name and extension will be
SRCINF1M.C32 or SRCINF2M.C32 for Simple projects (with a label), and SRCINF1I.C32 or SRCINF2I.C32 for
Structured projects.
*13 This file cannot be specified as a data storage file when the data logging function is used. To write data to the file,
execute the write PLC user data function.
*14 Only the High-speed Universal model QCPU and Universal model Process CPU can store these data in the memory.
*15 This file name depends on the connection type of the iQ Sensor Solution data backup/restoration function. (
