(2) Refresh of CC-Link IE and MELSECNET/H
(a) Refresh time of CC-Link IE and MELSECNET/H
This is the time required for executing refresh between a QCPU and a CC-Link IE module or MELSECNET/H
module. For each refresh time, refer to the following.
Reference manual for each network module used
(b) Calculating formula
In a multiple CPU system, if refresh is executed by a network module controlled by another CPU module during
refresh processing, the refresh time increases by the time obtained by the following calculation.
• For the Basic model QCPU
Use the following value for N6.
• For the High Performance model QCPU, Process CPU, and Universal model QCPU
Use the following value for N5.
