(2) Method of replacing High Performance model QCPU with Universal model QCPU
Replacement method varies depending on the settings in the PLC file tab of the PLC parameter dialog box.

program." is selected.
"Use the following file." is
selected.
TableApp.41 Replacement method
No change in parameter settings is required. Operation of the Universal model QCPU is the same
regardless of the file usability setting in the High Performance model QCPU.
When file usability is set to "Not used." in the High Performance model QCPU, delete the
corresponding program file (file register, initial device value, or comment), which uses the same name
as the program, from the target memory. The Universal model QCPU executes a program without
using a program file if no program file that uses the same name as the program exists in the target
memory.
