64 (8 when Basic model QCPU or safety CPU is
used)
Link scan time
The link scan time and transmission delay time differs between CC-Link IE Controller Network and
MELSECNET/H.
When replacing the system, check the link scan time and transmission delay time of the CC-Link IE
Controller Network. ( Page 244, CHAPTER 7)
Transmission delay time
Max. number of mountable
modules
Up to 4 (Varies depending on the CPU module
used. ( Page 40, Section 2.3)
Up to 4 (up to 1 when a Basic model QCPU or
safety CPU is used)
