Appendix 5.3.1
The Universal model QCPU does not support instructions listed in the following tables. Instructions need to be
replaced using replacing methods described in the tables. (If no instruction in the list is used, replacement is not
required.)

Instructions

Instructions not supported in the Universal model
QCPU and replacing methods
Replacing method
Instructions can be replaced using a replacement program.
Change the program so that the device offset values specified by
the IXSET instruction are directly set to the index modification
table using the MOV instruction.
• It is recommended to use GOT as an ASCII code display
device. ASCII codes stored in devices are directly displayed as
characters on GOT.
• Instructions can be replaced using a replacement program.
• It is recommended to use GOT as an ASCII code display
device. Device comments can be displayed on GOT.
• Comment data can be output to a display device in the
replacement program of the PR instruction after reading data
using the reading device comment data instruction
(COMRD(P)).
Instructions can be replaced using a replacement program.
Failure detection ladder patterns can be changed in a
replacement program.
• Use the PSCAN instruction instead of this instruction when low-
speed execution type programs are replaced with scan
execution type programs.
• No instruction can be used if low-speed execution type
programs are replaced with fixed scan execution type
programs.
Check a program execution status on the Program monitor list
screen of programming tool. For details, refer to Page 178,
Section 3.13.1 in this manual.
• It is recommended to use GOT as a numeral input device.
• Instructions can be replaced using a replacement program.
Store all programs to be executed in the program memory. The
Universal model QCPU can neither add programs to the program
memory nor change them with other programs during RUN. If the
capacity of the program memory is not enough, store parameters,
device comments, and initial device values in the program
memory into the standard ROM or a memory card instead.
