QCPU and software need to be upgraded
for the communication with the Universal
model QCPU are described in Appendix
3.2.
CPU modules compatible with the
Universal model QCPU are described in
Appendix 3.2.
Replacement method
Replace the instructions not supported in
the Universal model QCPU are described
in Appendix 3.3.
When the floating-point data comparison
instructions are used, modify the program
as described in Appendix 3.4.2.
Deselect the "Check device range at
indexing" checkbox in the PLC RAS tab of
