Cyclic Data Update Watch Function

The update intervals of cyclic data are monitored. The last output value is held or cleared when the cyclic transmission
stop status continues longer than the set monitoring time.
The cyclic transmission stop status is the status that the D LINK LED is flashing (Data link in operation (cyclic
transmission stopped)) or off (Data link not performed (disconnected)).
Set whether to hold or clear the output value using the output HOLD/CLEAR setting function. For the output
HOLD/CLEAR setting function, refer to the following.
• Output HOLD/CLEAR Setting Function ( Page 184, Section 9.6)
Monitoring starts when cyclic data
are received for the first time.
