Awesome man, Please make video for Function to detect DateTime from how long time input trigger on (High Status input PLC) include Elapsed time, thanks you
is it neccesary to use temporary value to write date and time value into target variable? why we cant just assign RD_SYS_T OUT to "OB Data"."Last Restart time"?
Hey...ur playlists for TIA are too good. Any automation engineer can become expert in TIA by following all ur playlists. Do u have same expertise in Rockwell? Or do u know any guy who has uploaded playlists like this on you tube.
Thank you! I have not worked with Rockwell too much... have no videos about it either. I know some people that work with it, but they don't make videos
It is only called ONCE in the beginning of your program (and only when the PLC starts up or goes from STOP -> RUN)... try SETting a bit in it to see if that worked!
Can you simulate the behavior of ob100 inside ob1 ? Like having a bit that is initially unset, then initialize your variables and then unset the bit? What would be the difference than to ob100 ?
There is a special bit you can use that does pretty much that: You can use the "First Scan Cycle" Bit from the "System Memory" Byte that you can activate in the device configuration. This Bit is only true in the very first execution of OB1. The difference to doing it with OB100 is that OB100 is only executed once (so only needs calculation once) and everything you evaluate in OB1 is evaluated every cycle, so it would be less efficient to do it that way
