SDO upload times

flosse opened this issue · 0 comments

I'm curious to understand why reading a SDO takes 25ms in operation mode whereas with the SOEM stack it takes only 2ms.
Do you have some experiences with this? Is this timing behavior caused by a bad configuration?

Here is my context:

  • v1.5.2-sncn-11
  • Ubuntu 18.04.4 LTS
  • Kernel 4.19.118
  • Intel Ethernet I218-LM / driver=e1000e
  • Cycle Time: 1ms
  • Slave: Weidmüller ur20 I/O system
