Description:
Basic cycle time of the system software
The cycle time settings of cyclical tasks (position controller/IPO) are multiples of
this basic cycle.
For PROFIBUS/PROFINET:
In the case of systems with a PROFIBUS DP connection, this MD corresponds to the
PROFIBUS DP cycle time. This time is read from the configuration file (SDB-Type-2000)
during startup and written to the MD.
This MD can only be changed via the configuration file.
Note:
Reducing this MD can result in an automatic correction of
MD10064 $MN_POSCTRL_CYCLE_DESVAL_DELAY
that cannot be undone by a subsequent increase!
Details:
The basic cycle is incremented in multiples of units of the measured value sampling
cycle. When the system powers up, the entered value is automatically rounded to a
multiple of this incrementation.
Note:
Discrete timer division ratios can give rise to the entered value producing a value
that is not an integer after a Power OFF/ON.
For example:
