Appendix 3.3.2 Replacing programs using multiple CPU transmission dedicated
instructions
(1) Replacing the module with the QnUD(H)CPU or Built-in Ethernet port QCPU
TableApp.26 shows instructions need to be replaced and corresponding alternative instructions. For
the specifications of each instruction, refer to the manuals for the Motion CPU.
(2) Replacing the module with the Q00UCPU, Q01UCPU, or Q02UCPU
The Q00UCPU, Q01UCPU, and Q02UCPU support the same multiple CPU transmission dedicated instructions
used in the Basic model QCPU. Replacing instructions is not necessary.
The alternative instructions in TableApp.27 are not available for those CPU modules.
