It is a shame not to be able to do this with the astro clock variable (sec, min, hours, number day, number month, year), do you think that in the next frimware this variable will be present? because of that I'll have to choose anothermimi plc the problem with your solution is that I'm not sure Synchronous with the actual time I have to use logosOBA7 for managedmy electrical consumption in my factory Here is what I did with a other small plc Thx!

Here you always get time&date and the value you want to record. Stored in internal LOGO! memory or on the SD-card. Read out: Internal memory and last datalog on SD-card via LSC V7. If you switch LOGO! RUN/STOP and you record to the SD-card, then after each pwer cycle you get a new datalog file on the SD-card. If you want ot read older files, then you have to unplug the SD-card and put in to your PC. The fiel is in CSV format so any SW like MS Excel can open it. However, LOGO! is a nano controller. Not any PLC function will be supported by LOGO!. If you have a sollution why you want to change? Never touch a running system! Hope this helps
