APPENDICES
Appendix 5.3 INSTRUCTIONS
Appendix 5.3.1 Instructions not Supported in Universal Model QCPU and
Alternative Methods
The Universal model QCPU does not support instructions listed in the TableApp.64 and
TableApp.65. Instructions need to be replaced using alternative methods described in the
tables. (As for instructions not listed in the tables below, replacement is not required.)
TableApp.64 Instructions not supported in the Universal model QCPU and alternative methods
Symbol Instruction Alternative method Reference
IX
Index modification of entire
ladder
Instructions can be replaced using a replacement program. Appendix 5.3 (1)
IXEND
IXDEV Modification value specification
in index modification of entire
ladder 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.
Appendix 5.3 (2)
IXSET
PR Print ASCII code 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.
Appendix 5.3 (3)
PRC Print comment instruction
• 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)).
CHKST
Specific format failure check
instruction
Instructions can be replaced using a replacement program.
Appendix 5.3 (4)
CHK
CHKCIR
Format change instruction for
CHK instruction Failure detection ladder patens can be changed in a
replacement program.
CHKEND
PLOW
Program low-speed execution
registration instruction
• 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.

PCHK
Program execution status check
instruction
Check a program execution status on the Program monitor
list screen of GX Developer. For details, refer to Section
6.13.1 in this manual.
---
KEY Numerical key input instruction
• It is recommended to use GOT as a numeral input
device.
• Instructions can be replaced using a replacement
program.
Appendix 5.3 (5)
PLOADP
Load program from memory
card 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 device
initial values in the program memory into the standard ROM
or memory card instead.
