Dear Community, is there any possiblility/interface to get the whole data from the Logbook? Not only one node. All. When yes? Where? How to find this peace of documentation? Are there anywhere more documentation? Sincerely  Elleshar  ... View more

Actual we are using SDK version 1.14. Our path to the datalayer-node is: fieldbuses/ethercat/master/instances/ethercatmaster/realtime_data/output The communication over the web-ui is working fine.

Hello community, we got the following problem. It's the same like https://stackoverflow.com/questions/54781218/execution-time-of-c-code-on-linux-for-the-first-time-is-extremly-slow At running our RealTime Application we get only one Watchdog-Error. It happens at the first execution, becuase we vialate the 2ms. Is there any chance of getting rid of this? e.g. like LD_BIND_NOW See below a snippet of the nano-seconds.
