script for hourly logging

[asaikk]

What would be the script for hourly logging, that is, to creat a new log-file hourly?

You can do it in an event, or just a low priority sequence. In a sequence it'd be something like:

while(1)
  logging.myLog.strFileName = "c:\data\myData_" + formatDateTime("%y%m%d_%H",systime()) + ".csv"
  delay(1)
endwhile

That would create a new file every hour where the date and hour is part of the file name.

Thank you for the quick response.

On some reference, the script for daily logging is written below;

<logging.log.strFileName = "c:\mydata_" + formatdatetime("%y%m%d",systime()) + ".csv">

compared with above, the one for hourly logging you mentiioned (below) is somewhat non-similar.

<logging.log.strFileName = "c:\mydata_" + formatdateTime("%y%m%d_%H") + ".csv">

Would you please explain the meanings of the commands below?

"%y%m%d"

"%y%m%d_%H"

systime()

I'm sorry, I typed it in wrong. There should be a ,systime() in the function similar to your script. The %H means the current hour of the day. %y is year, %m is month, %d is day. This and other codes are described in section 4.12.11 in the user's guide.

Thank you for your comment.

I will look up it on the Guide for more detail.

I installed the sequence of hourly log below on the DAQ Factory Express, but it does not work.

---------------------------------------------------------------------------------------------

while(1)

logging.log.strFileName = "C:\aa onlinesoft\datalogger\HourlyLog" + formatdatetime("%y%m%d_%H",systime()) + ".csv"

delay(1)

endwhile

---------------------------------------------------------------------------------------------

On the "Sequence Summary" window, this "HourlyLog" is shown to be "RUNNING", (see the attached figure).

What could be wrong?

First, is your logging set named "log"? I think the parser actually might have a problem with that because log() is a function for doing logarithm. So, first you might consider renaming your logging set. Second, does the file name change to something like HourlyLog120210_15.csv?
