H
(a) Refresh time of CC-Link IE controller network and MELSECNET/H
The amount of time required for performing the refresh between the QCPU and
the CC-Link IE controller network or MELSECNET/H network module.
For refresh time of CC-Link IE controller network and MELSECNET/H, refer to the
following manual.
CC-Link IE Controller Network System Reference Manual
Q Corresponding MESLECNET/H Network System Reference Manual
(b) Calculation of refresh time
In a multiple CPU system, when refresh is requested from a network module of
another CPU coincidentally, the refresh time increases by the time obtained from
each of the following calculations.
1) For Basic model QCPU
(Extension time) = 4
The number of transmission/reception words is the total number
of transfer data below.
Link refresh data
Use the values in Table5.9 for N6

The CC-Link IE controller network can only use the High Performance model QCPU whose first 5
digits of serial No. is 09012 or later.
The CC-Link IE controller network cannot use the Basic model QCPU or the Process CPU.
