Appendix 4 Comparison Between Cc-Link Ie Controller Network And Melsecnet/H; Appendix 4.1 Comparison Of Specifications - Mitsubishi Electric MELSEC Q Series Reference Manual

Appendix 4
This section describes the comparison of specifications between the CC-Link IE Controller Network and the
MELSECNET/H, precautions for system replacement, and precautions for program replacement.
Replace the system according to the description of this section.
Appendix 4.1
The following describes the comparison of specifications between the CC-Link IE Controller Network and the
MELSECNET/H.
(1) Comparison of performance specifications
The transmission of the CC-Link IE Controller Network is made by the optical loop system only.
When the coaxial bus system is used in the MELSECNET/H, consider to replace it with an optical loop system.
The following shows the comparison of optical loop systems in the CC-Link IE Controller Network and the
MELSECNET/H.
