3.10 Precautions for Use of File Registers
Remark
For the file register setting method and file register area securing method, refer to
User’s Manual (Functions Explanation, Program Fundamentals) for the CPU
module used.
(4) Designation of file register number in excess of the registered number of points
(a) CPUs other than Universal model QCPU
An error will not occur if data are written or read to or from the file registers that have
numbers greater than the registered number of points. However, note that the read/write
of correct data to/from the file registers cannot be performed.
(b) Universal model QCPU
When data are written to or read from the file registers that are not registered, an error
occurs. (Error code: 4101)
(5) File register specifying method
There are the block switching method and serial number access method to specify the file
registers.
(a) Block switching method
In the block switching method, specify the number of used file register points in units of
32k points (one block). For file registers of 32k points or more, specify the file registers
by switching the block No. to be used with the RSET instruction. Specify each block as
R0 to R32767.
