POINT
File registers dedicated to each program may not be designated with some
instructions. Refer to the allowable device in the programming manual of each
instruction for details.
(c) When selecting "Use the following file"
1) This setting should be selected when a given file register is to be
shared by all executed programs.
2) Specify the desired parameters in the "Corresponding memory", "File
name", and "Capacity" text boxes. The High Performance model
QCPU creates a file register file with the specified parameters. If a
parameter is not specified in the Capacity test box, this may result in
the following:
• If a file register file with the specified filename is stored on the
specified drive, that file register file is used.
• If a file register file with the specified filename is not found on the
specified drive, a “PARAMETER ERROR (3002)” will occur.
• When an ATA card is used, a memory card (ROM) cannot be
registered with the targeted memory. If a memory card is registered
with the targeted memory, a parameter error (3000) will occur when a
file register file is written to the High Performance model QCPU.
(2) File Register Setting
Use the device memory screen to specify a filename of a file register file.
