Googled a little, but didn't quite find the answer. I need to detect first scan of device so I found out in Beckhoff documentation about this data type: SYSTEMTASKINFOTYPE(http://infosys.beckhoff.com/english...m/html/tcplclibsys_systemtaskinfotype.htm&id=) which, among other variables, contains firstCycle variable (System library).
I don't know if I am missing something but I can't find a function which I could use to retrieve this variable, and I have searched among all functions and function blocks in System library.
Hopefully soon I will be able to help others the same way I am getting help on this very, very useful forum
