I used to think it meant "comma separated values", and I think that makes sense, except that somebody already thought of the usefulness of the comma in data. I just imported something like this file: fname:lname:stuff:number erastmus b.:dragging:techie:29 budd:tugly:makeup artist:22 into Libre Office Calc and the import feature allows a radio button choice of comma, semi-colon, and a few others, but allows you to choose practically ANY character you want to be the separator. It wants to have text surrounded by either single or double quote characters. I did a copy of the file with the colon replaced by the underscore character, and it imported fine also. While you could use Libre Office to import the CSV file, and write it out to an XLS file, I suspect that is not necessary. While I don't have a copy of Excel here to try it out, I suspect it allows semi-colon as a separator, and perhaps any other character. We have imported CSV files at work in the past. Someone wrote an app that takes data from our tester and writes it out as a CSV. We have an Excel spreadsheet that takes that data, and puts it into a nice, formatted data sheet we can send to customers.

Having said that, Stephen's suggestion about databases is cool if you
are willing to invest in learning them. A lot of issues such as 'will
the data be saved', 'what happens if we restart after power loss',
'which file is the latest one', are handled by the database: you write
EVERY data point, the database makes sure it finds its way to disk,
and you then use the database to sift good/relevant records out. If
you don't feel like running full MySQL system, you could run sqlite:
import sqlite3
conn=sqlite3.connect("example.db")
c=conn.cursor()
c.execute('create table planks (date text, length real)')
c.execute('insert into planks values
(\''+datetime.date.today().isoformat()+'\',12.44)')
conn.commit()
c.close()
and the data is there:
$ sqlite3 -line example.db 'select * from planks'
date = 2012-09-15
length = 12.44
length = 12.44

Re: [Emc-users] Counting and saving to file
This might be a little obtuse, but consider putting a small UPS on the computer and the monitor. Set the software that monitors the UPS to shut down the computer after a reasonable time automatically. The operator would have enough time, if they are around, to get to the computer and save the file, then shut down the rest of the operation gracefully. I use several UPS in my home, just for that reason, (and I hate to loose stuff because of a quick power glitch too!). Where I live, in the toolies outside Nashville, we have power spikes and outages regularly. A fact of living on the other end of long distribution lines. So I put UPSes on EVERYTHING electronic that I care about saving. A problem in our transformer put 220V over 110V lines intermittently (actually it was a poor ground at the transformer, and the power company fixed it but didn't admit it, so we just had to pay for our burned out equipment - I was there when the linemen got that 'oh stuff' look on their face, and took a short piece of grounding strap and climbed up by the transformer ... after that no more problems.). Anyway the UPSes I had saved the gear it was on, but others were toast. Even one UPS died. I opened it up and the transformer primary was burned out, and half the MOV's inside were black. Batteries were still good, but discharged. I kept them as spares for other UPSes and purchased a new UPS for that spot. ( I like refurbups.com and the APCC brand). We still lost half the light bulbs in the house, and about $400 of misc electronics to this power issue. But nothing behind the UPSes was lost. One UPS died (additional cost). Also, figure you replace batteries about every 3 years if you don't monitor the UPS, and every 4 if you do (just because you can tell when the battery is getting weak - monitor with computer software that 'just runs'.) -- How fast is your code? 3 out of 4 devs don\\\'t know how their code performs in production.

Do a file open, append line of data, file close with each reading. THis is a trivial activity for the computer. Then to satisfy the customer, have the save button copy the contents of this "Shift" file to a final file. That way, if there is a power failure (and the operator has not hit the save button for 4 hours) and the customer calls you, you can tell them to look for this "shift file" to get the data they thought long gone. DUring a machine startup and or shut down, you can have the contents of the file saved to the daily file then purge the "shift" file.

That is what CSV is, "comma separated variables". The special
character is a comma.
It is also a really bad choice, as a large proportion of the world use
the comma as a decimals separator.

Just write("x,y,z") and it's CSV.

What is the syntax to put current date in the file name. In Your
example the file name is xyz.
And how can I specify the folder, in which the file is saved?

Yesterday I saw a video, where they demonstrated, how such a machine
is working. Each new piece of wood plank is created every 2 or 3
seconds. We agreed that saving to a file will be done, when operator
explicitly presses "save" button. So they are taking a risk that
powerfailure will cause a loss of unsaved data. I just cannot figure
out, how to create a reminder for operator to save data in case he/she
is trying to close application with some unsaved numbers.
Yes, saving to csv would be nice, but I think that I have a solution -
put in the rows some special characters, like semicolon, and then use
"text to columns" function in spreadsheet. What I am concerned about
is the coding of the file - most likely they will import the file in
excel on windows.

As it turns out, opening the file in append mode creates it if it
doesn't exist, so you can just do
x=open("xyz","a")
x.write("abc")
if you needed to do some more housekeeping if the file didn't exist,
you could do the explicit test:
import os
if os.path.isfile("xyz"):
print "file exists"

Re: [Emc-users] Counting and saving to file
Seems like the data collection would work with a python dictionary. For
example you set up a dictionary entry for how many ranges they want then
each time a board falls inside of a range set by the operator you
increment the integer for that dictionary entry.
http://www.tutorialspoint.com/python/python_dictionary.htm
http://www.tutorialspoint.com/python/python_basic_operators.htm
A simple example.
create a dictionary
dict = {'range1':0, 'range2':0, 'range3':0}
the operator enters the low and high values for each range
update the dictionary
if measure >= range1_low and measure < range1_high:
dict['range1'] += 1;
elseif measure >= range2_low and measure < range2_high:
dict['range2'] += 1;
...
At some triggered point you could append the data to the file using the
file I/O and clear the dictionary counter once a successful file write
occurred.
Also look at the simple example for the winder to see how to make a
gladevcp panel and run it with HAL.

I apologize if I have misunderstood your problem, or if you have already incorporated these engineering techniques, but here is my "change your environment" solution : 1. Place the object to be detected into a "V block on the bed of the DRO machine, to position the object in a standard and known location, 2. Use a highly modified version of "smartprobe.ngc", from the Example folder of EMC2 /LinuxCNC, to write a file of the points of the object, 3. Scan the file, (using "AWK" or "SED"), to identify the beginning and the end of the object, (looking for the transitions from Height = Bed -> Height = Object, and reverse), 4. Calculate the length from the identified end points, Bin the parts into the various lengths, and recalculate statistics on the various Bins. Drawback: I use SED, I do not use AWK. I find it awkward, compared to C. You have to know the height differences you are searching for, before writing your scanning program. I suspect "smartprobe.ngc" is dog slow, based on the number of points to scan. Each new object must have the length program verified, and modified. Maybe that is job security, these days. Improvements: A mod version of "smartprobe.ngc" would need to know the location of the object. Put the object and the V block on a 30 or 45 degree angle, and you might only have to probe for one surface, (depending on your object), and with the X-Y-Z surfaces on this same angle, with support, you might not have to math out any trig distances, again, object dependant). Thank you for putting the problem up on the forum. I had a long day. J'aime mon solution. James Isaac. -- Got visibility? Most devs has no idea what their production app looks like.

Yes, You are correct that this case would require only HAL with "encoder" component to display the position of material and with some glade panel and classicladder or some custom HAL component to determine, in which range of length does current position fall into.

The only missing part is an executable file that can be used to start the system, something like #! /bin/bash loadrt -I -f thingycounter.hal -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

This is a pretty good tutorial on file I/O in python http://en.wikibooks.org/wiki/Non-Programmer%27s_Tutorial_for_Python_3/File_IO Have you seen my tutorials on gladevcp and building a gui from scratch?

I think that a GladeVCP panel might be most suitable, and file access should be easy from there. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

[Emc-users] Counting and saving to file
Hello! I am asked, if I can make a DRO machine that simply measures the length of parts and displays the length of the part on the screen. I find that to be easy task. What I do not understand, how to implement is: Client wants to define some ranges of the lengths and they want machine to count, how many parts fall in particular range and then save these data to a file. I think that use of ClassicLadder will handle counting number of parts in particular range, and export the counted number to HAL pin to be displayed in VCP. But how can I write those data to a file? -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
