Time Studdies Ugh! was created by Todd Zuercher

It has been decreed "Thou shalt keep track."

I need to figure out a way to log the time usage of several of our machines.
I would like to be able to automatically log the total time the machine is milling in a day, and the time that it is powered on/off.

Any suggestions how to make this happen?

I was hoping that without to much difficutlty the machine could build a log file, (say when it it powered down for the day and save it to someplace on our network. In that file I would like to see Something like this:

Milling Time	Power On	Power Off
HH;MM	Date, Time	Date, Time
HH;MM	Date, Time	Date, Time
HH;MM	Date, Time	Date, Time
HH;MM	Date, Time	Date, Time

As a starting point, the python program:
www.panix.com/~dgarrett/stuff/timelog.py

creates hal pins named:
timelog.start
timelog.stop

The program writes the Begin time, the End time,
the times for each Start and Stop button press,
and the time delta between a start and stop.

To use:

1) start linuxcnc with this hal commnand included in a halfile

   loadusr timelog.py -W

2) to watch the log, in a separate terminal (after starting linuxcnc)

   tail -f /tmp/timelog.txt

3) in another separate terminal, simulate the start, stop pins:

   sim_pin timelog.start timelog.start

Note:
1) timelog.py should be in the ini directory
2) if using RIP, source scripts/rip-environment for each terminal
3) an early version of sim_pin is in v2.5.2
4) edit the file to change the name of the log file (/tmp/timelog.txt)

Thank you very, much. Unfortunately I've been way to busy to try it out. It sounds like exactly what we need, can't wait to try it.

I tried to test it, but after placing the file timelog.py in my config directory where my ini file is,
adding

loadusr timelog.py -W

to the hal file and starting LinuCNC, I get the error

custom_postgui.hal:4: execv(timelog.py): No such file or directory

Should there be something else somewhere pointing to the location of the file or did I not put it in the right place?

my mistake:

$ man halcmd
...
loadusr [flags] unix-command
...

for loadusr, the unix-command must be in the user PATH or specify with absolute path. So
if you put in in the ini directory, invoke as:

loadusr -W ./timelog.py

Thanks that fixed it.

Now to work on fine tuning the output of the Log file.

I think I would like to have the power on/off connected to the machine power on/off (F2) rather than just LinuxCNC starting and stopping.
2nd, right now this is what the log file looks like.

Begin Fri Feb 28 11:02:09 2014

UNEXPECTED: received stop while waiting for start
Start: Fri Feb 28 11:04:19 2014
Stop:  Fri Feb 28 11:04:26 2014 Elapsed: 7.229313

Start: Fri Feb 28 11:04:43 2014
Stop:  Fri Feb 28 11:04:43 2014 Elapsed: 0.401248

Start: Fri Feb 28 11:05:05 2014
Stop:  Fri Feb 28 11:05:06 2014 Elapsed: 1.103536

Start: Fri Feb 28 11:05:18 2014
Stop:  Fri Feb 28 11:05:20 2014 Elapsed: 1.805242

Start: Fri Feb 28 11:17:08 2014
Stop:  Fri Feb 28 11:17:10 2014 Elapsed: 1.908865



End: Fri Feb 28 11:19:21 2014 Time since start: 1031.970063

How hard would it be to make it look more like this

Power On Fri Feb 28 11:02:09 2014

Start: Fri Feb 28 11:04:19 2014     Stop:  Fri Feb 28 11:04:26 2014     Elapsed: 7.229313
Start: Fri Feb 28 11:04:43 2014     Stop:  Fri Feb 28 11:04:43 2014     Elapsed: 0.401248
Start: Fri Feb 28 11:05:05 2014     Stop:  Fri Feb 28 11:05:06 2014     Elapsed: 1.103536
Start: Fri Feb 28 11:05:18 2014     Stop:  Fri Feb 28 11:05:20 2014     Elapsed: 1.805242
Start: Fri Feb 28 11:17:08 2014     Stop:  Fri Feb 28 11:17:10 2014     Elapsed: 1.908865

Power Off: Fri Feb 28 11:19:21 2014 Time since Power On: 1031.970063

I don't really know anything about progamming Python code, but I was able to figure out how to make the Start, Stop and Elapsed time go on one line and space it appart a bit like I wanted it.

But I think I will need some help adding an input pin or two to cause the power on/off work right.

My next question is: Is is nessisary to have seperate Start and Stop pins? Why can't the program just log the time when start pin goes true, then log when it goes false as the stop time?
