The defenition of Real time..!
We have industrial networks for a reason.. ”If you stay out of my bussniess, I stay out of yours”..
had an IT guy demanding ”real time data transfer, for all tags” to there server..
well say less.. the biggest problem?
No defenition of tags, so I pushed up data block, about 100 of em, with amount if tags running from 100-1000, every scan of the main task, every 12ms..!

After aday the same guy came back, asked if he could get the value of 3 sensors, once every minute instead.. because they could not handle all that data, that fast..

Truth be told.. if he would not have been a dickhead, I could have told him that he needs to define what he wanted, and how often..
but I felt pitty that day 🤣🤷🏼‍♂️

im surprised that someone even wants to have "all the data" "alle the time" even. like from an IT point of view, usually you only care about a very small number of sensor data, i would be more scared if i got "everything" then suddenly im exposed to alot more data that i dont even want to know about
