Hello TI team,
I am currently working with the following setup:
- AM261x-LP
- ICSDK_10_02
- S7-1500-PLC
According to the TI Profinet documentation, the fast startup time should be 625 ms. I have followed all the recommended steps, including setting the device to “priority startup” in TIA Portal and building my code in Release configuration from CCS. However, I am consistently measuring a startup time around ~870 ms.
Could you please help me understand where I might be going wrong? I have attached links/photos for your reference.

Yellow line: Device power-up
Green line: first output profinet frame receive on device
Profine Device: PROFINET Device4.2.0 datasheet
Thank you for your support!
Best regards,
Parag Vora
