Number of elementary instructions for time check (P-CHAN-00426)

P-CHAN-00426

Number of elementary instructions for time check

Description

This parameter defines the number of elementary instructions after which another time check is executed.

 

A check for the execution time of realtime cycles must be made within a CNC cycle to see whether the permitted execution time is already exceeded. This takes place by checking the expired time after a specific number of elementary instructions in a cycle. Parameter P-CHAN-00426 indicates the number of these elementary instructions.

Parameter

rt_cycles.cont_steps

Data type

UNS32

Data range

0 < P-CHAN-00426 < MAX_UNS32

Dimension

----

Default value

100

Remarks

The user has no restrictions regarding the number of instructions within a realtime cycle.

Realtime timeouts will occur if realtime cycles contain too many instructions and cannot be executed in one CNC cycle,

 

The parameters P-CHAN-00425 and P-CHAN-00427 represent a safety mechanism to prevent such realtime timeouts as early as possible.
