4.3 CC-Link Module Access Function
4.3.1 Data consistency verification per station function
POINT
When one of the following operations is performed to the CC-Link module where
the data consistency verification per station function is set, the cyclic data are
automatically refreshed even if the QBF_RefreshLinkDevice function is not
executed.
• Monitoring on the Module monitoring screen of the C Controller setting
utility
• Monitoring on the Device monitoring utility
• Reading data from the device using the QBF_FromBuf function (auto
refresh) or the MELSEC data link function (Q06CCPU-V only) from other
user program (other task)
Note that the write (transmission) area of link refresh devices (buffer memory) is
not refreshed.
The cyclic data are not refreshed when monitoring is performed specifying a CC-
Link module on other stations using the Device monitoring utility.
Use the manual cyclic data refresh method if user program execution is desired
even during the waiting time of the user program, since the waiting time is
generated when using the automatic cyclic data refresh method.
