- 123 Appendix 5 Method of replacing High Performance model QCPU with Universal model QCPU
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.)
Instruction
Instructions can be replaced using a replacement program. Appendix 5.3 (1)
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
• Instructions can be replaced using a replacement
• It is recommended to use GOT as an ASCII code display
• Comment data can be output to a display device in the
Instructions can be replaced using a replacement program.
Failure detection ladder patens can be changed in a
replacement program.
• Use the PSCAN instruction instead of this instruction
• No instruction can be used if low-speed execution type
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.
• It is recommended to use GOT as a numeral input
• Instructions can be replaced using a replacement
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.
Alternative method
