3. Click the "Options" button to make additional settings for PROFIBUS. In the
"Constant bus cycle time" tab, activate the "Activate constant bus cycle time" function.
Also activate the "Slave Synchronization" to keep the time values identical for all
connected slaves. Then click the "Recalculate" button to calculate the constant
DP cycle time and the T
i
and T
o
times. Round up the calculated constant DP cycle time
(0.250 ms step) and enter the rounded value in the input box.
Recommended rounded values are, for example, 1.5 ms or 2.0 ms.
Click the "OK" button to confirm the settings. The configured objects are then added to
the SIMATIC 300 station.
4. To automatically generate the technology system data, open the object properties
in the shortcut menu of the technology. In the "Technology system data" tab,
activate the "Generate technology system data" function.
