CC-Link IE Field Network Function

8.4.1

Cyclic data update watch function

This function is used to watch the time interval between updates on cyclic data. When an update by cyclic transmission
remains to be done for a set period of time for watching, the module "continues its operation and produces external
outputs (HOLD)" or "stops its operation and external outputs (CLEAR)".
A halt in cyclic transmission is indicated by the status of the D LINK LED, flashing (data link established (cyclic
transmission stopped)) or off (data link not established (disconnected)).
Set either HOLD or CLEAR with the control output setting at CPU stop error.
For the control output setting at CPU stop error, refer to the following.
• HOLD/CLEAR function (Page 148, Section 8.3.2)
