Setting the send cycle in HW Config

The PROFINET send cycle always forms the basis of the SIMOTION cycles if RT class IRT is set and data is in actual fact transferred. Set the send cycle in the "Domain Management" dialog box of HW Config. Open this dialog by selecting the "Edit" > "PROFINET IO" > "Domain Management ..." command in HW Config.

The set PROFINET send cycle is displayed in SIMOTION SCOUT as "Bus cycle" in the "System Clocks - D410..." dialog box. Select the SIMOTION D410 PN in the project tree, and then select the "Set system clocks" option in the "Target system" > "Expert" menu.

The PROFINET interface supports send cycle times within the range 0.5 ms < send cycle < 4 ms. The maximum configurable resolution is 0.125 ms.

The table below shows which ratios you can set for the system clocks of SIMOTION D410 PN based on the DP cycle of SINAMICS Integrated or on the PROFINET send cycle.
