Program Continuation:

NCU link connection to all other NCUs of the link network has been aborted

All NCUs in the NCU link network exchange data cyclically (sign-of-life). If this alarm occurs, sign-of-life signals have not been received from any other NCUs on the NCU network. This fault in the link can have various causes:

Defective hardware.

The machine data which configure the NCU link are not the same on all NCUs.

An identical interpolator cycle time has not been selected on all NCUs.

-    NC not ready.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Check the IPO cycle on all the NCUs.

If necessary, check NCU link-specific alarms first.

Switch control OFF - ON.
