Lockie posted a topic in Channels, Conversions and general data acquisitionHi I am struggling to log (and graph) a number of global variables that have been calculated in sequences. Have got the graphing working but it wont log the data for me. I have logging set up for raw data from inputs and am wanting to log the global variables for a few hours at a time so from what I can see logging may be better suited than export sets. I have created a test channel for each variable I want to log (and graph) as below: I then have a sequence running to make the variable a string in the channel While (1) Graph_DT_Flow.AddValue(insertTime(DT_Flow,systime(),0)) Graph_kW.AddValue(insertTime(kW,systime(),0)) delay(1) endwhile This allows me to graph the channels which is working but when I try to log them the column when opened in excel only has the heading. If you could help with this it would be amazing!!
