Using more bandwidth for cyclic IO data
Requirement: The "Make 'high performance' possible" option is enabled.
To set more bandwidth for cyclic IO data for your PROFINET IO system, follow these steps:
1.
Select your IO system in the network view of STEP 7.
2.
In the Inspector window, go to "Properties" > "General" > "PROFINET" > "Domain
management" > "Sync domains" > "Name of the sync domain" > "Details".
3.
In the drop-down list, select "Maximum 90% cyclic IO data. Focus on cyclic IO data".
Figure 5-65 Using more bandwidth for cyclic IO data
Note
Bandwidth usage in isochronous mode
If you operate your PROFINET IO system in isochronous mode, avoid using the setting for the
bandwidth usage "Maximum 90% cyclic IO data. Focus on cyclic IO data."
Setting low send clocks (example CPU 1518-4 PN/DP)
Requirement: The "Make 'high performance' possible" option is enabled.
1.
