(a) Registration memory
Select a memory where the file register file is to be registered from the following.
• Standard RAM
• Memory card (SRAM)
• Memory card (Flash)
To use the same file name that is used in the program, register the file register file to the memory specified in
the PLC File tab of the PLC parameter dialog box.
(b) File register size of the CPU module
The file register size can be set in increments of one point. Note that each file size is ensured in units of 256
points. Even if a file register is not specified from ZR0, the created file will have an assignment from ZR0 to the
last number.
If the write range of a file register is specified to be ZR1000 to ZR1791, the created file register file will
Ex.
have an assignment from ZR0 to ZR1791. However, because the data in ZR0 to ZR999 are unreliable,
specify the file register from ZR0. The size of the file register is checked in the units of 1K points.
Therefore, the file register size must be specified from R0 in the units of 1K points.
