3.4.17 Server trigger on "Cyclic trigger on variable monitors"

Function description

These server triggers are initiated when limits or intervals are reached/exceeded.

These limits/intervals can be configured for variables if these are read cyclically

from the control and were defined as counters. (Endless counters in

SINUMERIK Integrate can not be reset, even when the variable is reset.)

Cyclic trigger on variables

A cyclic trigger on a variable requires a variable defined as counter. These are

processed as "endless counters" (without zero crossing) so that the intervals are

always consistent. When a configured interval value is reached or exceeded, the

trigger is initiated.

Notice

Cyclic triggers for NC variable data can only be created as a template if an axis

configuration is available.

Since the endless counter function of the NC cannot be guaranteed when

components are exchanged, when a smaller new value is read,

SINUMERIK Integrate adds a read small new value as an offset to the old value.
