- 167 Appendix 5 Method of replacing High Performance model QCPU with Universal model QCPU
TableApp.85 lists special registers not supported in the Universal model QCPU and
measures to be taken.
The Universal model QCPU does not support the CHK instruction.For the alternative
method of the CHK instruction, refer to Appendix 5.3.
The Universal model QCPU does not support the step transition monitoring timer
function.For the alternative method of this function, refer to "Appendix 3. Restrictions
and alternative method of the Basic model QCPU and Universal model QCPU" in the
"QCPU (Q Mode)/QnACPU Programming Manual (SFC)".
Replace these registers with the I/O signals (Xn0, Xn1, XnF) of the mounted CC-Link

module.

Service processing setting is available for the Universal model QCPU on the PLC
system setting tab of PLC parameter.
Select "Specify service process time." in the service processing setting and set the
service processing time. Other setting methods can be selected as well.
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding part or replace it with the special register for scan
execution type programs (SD420).
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding part or replace it with the special register for scan
execution type programs (SD500).
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding parts or replace them with the special registers for
scan execution type programs (SD520 and SD521).
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding parts or replace them with the special registers for
scan execution type programs (SD524 to SD527).
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding parts.
The Universal model QCPU does not support low-speed execution type
programs.Delete the corresponding parts.
The Universal model QCPU does not support the service interval measurement
function.Delete the corresponding parts.
