Re: [Emc-users] touch screen with emc2
Here is what worked for me to implement the LG 1730 touch screen: 1. sudo apt-get install xserver-xorg-input-evtouch (0.0.8-3build1) 2. put the following file in /usr/lib/X11/xorg.conf.d/ Section "InputClass" Identifier "touchscreen catchall" MatchIsTouchscreen "on" MatchDevicePath "/dev/input/event*" Driver "evtouch" Option "MinX" "295" Option "MaxX" "3815" Option "MinY" "200" Option "MaxY" "3948" Option "Emulate3Buttons" "true" Option "Emulate3Timeout" "50" Option "SwapX" "1" Option "SendCoreEvents" "on" Option "Rotate" "ccw" Option "ReportingMode" "raw" ## Option "Calibrate" "1" EndSection Note that this is not in the usual /etc/X11/xorg.conf file - linux developers just can't resist moving things around in circles! It took me some searching to find this place. The calibration I have not found necessary so far. Hope it also works other users.

Re: [Emc-users] Lucid Based Live CD Failure on N15235 Intel Atom Motherboard
Hi All: I was on the linuxCNC.org website and could not find a place to post an issue. I experienced a failure with the Lucid based live CD image on my new Atom based motherboard. Steps Taken. 1. Downloaded Ubuntu 10.04 based live cd image. 2. Used UNetbootin to make a turn this into a Live USB image. 3. Booted the system 4. Ran Latency Test. System froze on exit from latency test. 4a. Rebooted 5. Started system install, but system froze during disk partitioning. 6. Ran memtest, passed. 7. Downloaded Ubuntu 8.04 based live cd image. 8. Used UNetbootin to make a live USB image. 9. Booted the system and installed just fine. System stats. Motherboard. Foxcon N15235 Intel Atom 335 system. Memory PC-533 1GB Dimm. Onyx 30 GB SSD hard drive. I've had the Hardy based system running for almost 24 hours now doing dummy runs with no issues. It's interesting to note that Lucid has ~15% better latency numbers than Hardy. I'll do a more through search of the archive and see if someone has had this same issue and to see if it was solved.

I've been playing around with this a bit. My plan was to build a simple board that read encoder signals, and outputted a PWM signal. I'm aiming for the 1ms update. I've built an implementation (a poor one) of RT-Net that runs on a atmel NGW100 demo board. The Ethernet part mostly worked, but I wasn't able to read the encoders and generate the PWM signals fast enough. I just ordered a XMOS XC-2 ethernet development kit. The XMOS CPU has 4 cores with 8 threads each and sample Ethernet source code. Hopefully the one chip can do it all. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

You don't allow multiple servers.You don't allow CSMA/CD What you do is master - slave with a fixed, timed transfer. No Collisions and this way you get realtime with ethernet and UDP/IP. Additionally, they sell hardware swiches with defined timings. And because one ethernet frame has max 1486bytes their special hardware asics insert the bits and bytes into the frame as it is transmitted through the system. They don't send a frame for each component. So the guys at beckoff advertise cycle times as low as 100µs for 100 servo axis. And this system is indeed capable of running printing machines and packaging machines.

[Emc-users] history of emc
Gentle persons: Since there is interest in gathering information for a new Wikipedia article on EMC and since there has been some gratuitous O/S bashing going on recently, I thought I would kill two birds with one stone by recommending y'all read (or reread) the NIST report "Enhanced Machine Control Architecture Overview" NISTIR-5331, by Fred Proctor and John Michaloski [ http://www.nist.gov/manuscript-publication-search.cfm?pub_id=820482 ].* It nicely describes the intentions of the Systems Integration Group in developing EMC and tells how it fits into the larger Real-time Control System (RCS) architecture championed by Jim Albus. A fundamental goal of their group, like that of my own, was to develop and help promulgate standards that enabled the interoperability of many different, proprietary systems. The EMC work did not pick an operating system, it helped the industry refine functional requirements for operating systems used in machine control. Look, for example, at section 9.1 in the NISTIR. "The operating system is specified by the SOSAS [Specification for an Open System Architecture Standard; from the Next Generation Controller project] to be POSIX-compliant. POSIX does not specific a particular operating system, but the interfaces to systems programmers that operating systems must provide "It is anticipated that full support of POSIX functionality (let alone exact compliance) will not be required for a machine controller, but that a subset is more appropriate. Part of the purpose of the implementation of the EMC project, at least as far as the Laboratory Development Controller is concerned, is to define that subset. At this point, it is clear that at a minimum, we need the functionality of the POSIX real-time extensions for semaphores, shared memory, clocks and timers, interprocess communication..., and threads. However, we feel that it is inappropriate and unnecessary to declare that the operating system be POSIX-compliant, in the same way that we would not declare that controllers use the VME bus. [good thing, anyone here still using any VME boards?] Other suitable and popular operating systems exist that we feel vendors will select based on their market." I know Fred and his colleagues struggled to make EMC run on as many different hardware and software systems as they could, precisely because these systems were representative of the market they were serving. As researchers, however, they were limited in what they could accomplish. Had New Mexico Institute of Mining and Technology not been developing RT-Linux in the same time period, Linux could not have been used. Had a similar product for Windows NT been available to the project, Windows NT would have been included in the mix. (After all, even MSDOS was being used in some of the AMRF at the time!) If you look at the original EMC and RCS code, you'll see conditionals for all manner of systems. If I recall, they played with VxWorks for example, which was very popular in some other NIST projects of the time. I'm sure there's conditionals for SunOS and possibly for VAX/VMS. At the time, I had a DEC Alpha and several SGI boxes in my own lab at the other end of NIST. Had I been involved with EMC, we'd probably have some DEC OSF/1 and SGI Irix conditionals in the code too. The bottom line is, don't bash the systems, demand the functionality. Just my 2 cents worth. Regards, Kent *note that the NIST publications are not subject to copyright. While this means you can freely distribute this report, please, as a courtesy to NIST, do not embed it on a website or blog. Rather, post the link for others to access so NIST can show the bean counters downtown that people are accessing its work products, e.g., that its work is relevant. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I'm familiar with the general scope of manufacturing base in the midwest as I used to sell industrial automation controls across most of it. Aerospace machining and EDM specialized services is a lot different than the traditional machine shop work being done in the typical midwest machine shop. The typical midwest machine shop serves local customers, mostly manufacturers, and the problem for them is that their customer base is simply going away. The manufacturers have either gone out of business due to foreign competition or else they have shrunk to the point where they have so much excess capacity that they simply don't need many outside services any longer. It only takes a drive through any of the industrial parks outside of any midwest city to see that the manufacturers are simply gone. In Livonia, on the outskirts of Detroit where I grew up, there is a stretch of industrial parks where literally every other building is vacant and for sale or lease. In many cases it is not that manufacturers moved their operations overseas, it is the case that the company that used to make "Widgets for Ford in Livonia etc" no longer exists, and the company now supplying the same widget is located in China. No amount of enticement is going to move those companies from China to the US. The Chinese gov won't allow it. They play by different rules. So the problem is bigger than just enticing the manufacturers to now buy services from the US instead of overseas. >>On the other hand, I don't work there anymore (and I use EMC) :-).

Re: [Emc-users] Old Iron in Redmond
Yep, Venturecom came out with Windows RTX running on Windows NT a long time ago. I think that same software package or company has been bought and sold now 2 or 3 times. Here it is... http://www.intervalzero.com/ About two years ago I inquired about the price per copy of Windows RTX running under Windows XP and they wouldn't give me a price via email, a distributor contacted me a few days later. I never did get a price but you can bet it was more than a few hundred bucks. I have heard it is in the $1000 plus range per copy for low volume users. I used to work with some Siemens software that ran on Windows RTX and it was very stable. Chrysler has several transmission assembly lines that are run via PCs. The software is based on Siemens soft S7 PLC software engine. Siemens MMI software runs on the same PC and hooks in the virtual PLC so it all runs on the same box.The PLC scan/loop time is in the 1 millisecond range which is fast enough for general machine control. For I/O the standard interface used to be Profibus, but I think that the current versions also support Profinet which is more or less Profibus over Ethernet. The application your run on Windows RTX has to be programmed specifically for Windows RTX, you can't just load Windows RTX, load up Mach3 and have Mach3 run in real time.Part of what IntervalZero sells is the development environment support for the OS, so you can use it with the typical Windows programming tools from Microsoft.

The 4I68 is a PC/104-PCI card, not PC/104 so you need to make sure your
carrier CPU is PC/104 plus or PC/104 PCI not just PC/104. The 4I68 is
supported by the HostMot2 driver so the EMC configs should be identical except
for low level signal names (and the low level names are pretty well hidden by
the sample HAL files)

The 4I34, 4I38, 4I39 are PC/104 cards (ISA) I have not bothered to make a
HostMot2 config for these cards so I think they will remain unsupported.

Subject: Re: [Emc-users] Using Ethernet to communicate with components
Hi Igor
I thought of that, too. you can use Ethernet/IP or EtherCat.
On the other site there is CAN-BUS (non-tcp)
Just sitting on my table desk I have a setup running with Beckhoff EtherCat(TM)
components. I bought their thesting kit and got it to work with emc.
it runs with etherlab on top of rtai and I have adapted the glue code to create
the i/o-pins for the componbents. You need one of the compartible ethernet
chipsets (intel or realtek) to have a realtime driver.
You can even drive their motor controllers directly by providing a position
signal.
Prices may vary, but to get an impression:
Testing kit (bus interface, 2x4I,2x4O) is around €200, a 32bit incremental
encoder input is €188, 8 digital-I are €35, 8 digital-O are €39, 2 analog-O
16bit €145, a 4 axis motor interface
(4x16bit-incs&4x+/-10V-analog&16xI-digital,16xO-digital,plugs) is €510.
I will set up a wiki page with more info soon.

BTW we should have Ethercat interfaced Anything I/O card out fairly soon. (The
7I62) it has 96 I/O. We have it (barely) working on the bench. We are hoping
to be able to support HostMot2 firmware with relatively minor driver changes
to the HostMot2 driver.

That is not quite correct. The result of NIST's work is work under Public Domain - as is everything that results from public funding in the US. NIST registered the Project at sourceforge sometimes around (or just before) september 2000 - maybe someone has a more precise date? [1] The code released by NIST "into the wild" called emc (also known as EMC1) is to this day mostly Public Domain, with various contributions that mention (or don't) proper copyright and licensing informations - a big mess mostly. In 2003 emc2 was born: it's a partial rewrite of emc1, with only PD code rewritten/merged as GPLv2 code [2]. Since then (mostly) all development has happend for emc2 (under GPL or LGPL).

You specify how many of each type of component you want in the HAL file init string. If you specify no step-dir modules then all those pins become available as general IO. This is also true of unused pins on the headers that connect to daughter boards, but breaking those out to use them is a little more difficult (but it is a physical wiring issue, not a software/configuration one) > Can i handle these 6 axis and some I/O with using one > 5i20? Yes. However, as the other respondant said, consider getting the 5i23. That supports a wider range of firmwares, including one that lets you hang 8x 8i20 off of a single header. Note that there is no 8i20 support at the EMC2 end of the chain at the moment, but it is being actively worked on. -- atp -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users This communication is for the use of the intended recipient only.

You specify how many of each type of component you want in the HAL file init string. If you specify no step-dir modules then all those pins become available as general IO. This is also true of unused pins on the headers that connect to daughter boards, but breaking those out to use them is a little more difficult (but it is a physical wiring issue, not a software/configuration one) > Can i handle these 6 axis and some I/O with using one > 5i20? Yes. However, as the other respondant said, consider getting the 5i23. That supports a wider range of firmwares, including one that lets you hang 8x 8i20 off of a single header. Note that there is no 8i20 support at the EMC2 end of the chain at the moment, but it is being actively worked on. -- atp -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

There was also a fatal flaw in the hal code I posted; no source for the speed signal. Just put the various lines in your HAL file. Put the loadrt and addf lines with the similar lines in the file, then put the rest anywhere you want. this line: net spindle-rpm-unfiltered => lowpass.0.in Has a bit missing, it ought to read net spindle-rpm-raw encoder.0.velocity => lowpass.0.in (assuming that the spindle speed is the velocity output of encoder.0) It is worth noting that "spindle-speed-raw" could just as easily be "sig2", "linux_ftw" or anything else that makes most sense to you. -- atp -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

The most interesting thing for this is that with emc you can mix the old analog drives whatever they are with modern digital ones. This way you are able to only partly renew your machine and have a highly productive control system (EMC). And if you have to replace some more of the old components, you can switch them to digital as you like. Another thing is that you can use standard panel pcs wich are not able to carry a full pci card. You can put them in your pendant and you only need a network cable to the control cabinet.

Well, technically, he also is offering machining services as an outsourced partner. But, if I understand You correctly, the goal is to the job inside the US, opposite to current situation that jobs are outsourced to partners outside the US. The idea is very nice, and there are several points of BUT: 1) existing providers of the outsourced machining service might have objective reasons for a cost advantage - starting from cheaper labor to cheaper premises, electricity etc 2) existing providers might be closer equipment manufacturer and get their machinery cheaper thus also contributing to cost advantage 3) they might be closer to material sources 4) there must be other reasons for cost advantages These things can be dealt and one can overcome them, I just think that somebody else might already have done that.

Re: [Emc-users] Using Ethernet to communicate with components
Hi Igor, > I think that the trend in industrial machines, is to use Ethernet as > much as possible inside industrial machines. On the surface, it > appears to be a very attractive option, with all devices hooked up to > the network switch and communicating seamlessly, without the mess of > wires. What are the implications of this for EMC? I think you have industrial ethernet based, so called fieldbusses, in mind. (fieldbus=realtime bus for industrial applications). There are several solutions like EtherCAT, PROFINet, Ethernet powerlink, EthernetIP, Sercos III and so on. We created a similar solution with a "old fashioned" fieldbus, so we can estimate what it means to make the EMC "ethernet-compatible". We choose CAN with CANOpen protocol. Because of the CAN limitation to 1Mbit/s we had to use 2 CAN busses. We ported our CANOpen multimaster stack on RTAI Linux and used it to control standard hardware (Danaher servostar 600 servo converter, telemecanic converter (Altivar 31) and beckhoff I/O for auxillary tasks) The resulting solution is very smart regarding the cableing and the diagnostics that can be done using a fieldbus. And of course it fullfills the industrial effords of electrical isolation and installation. However, the solution is NOT very portabel, because standardisation of CANOpen profiles are not detailed enought / are not implemented in perfect way by the manufacturers. This is not a problem for the simple I/O or simple converter. But to close the servoloop over a bus needs to tune communication and servo parameters in deep detail. And this tuning parameters are not implemented in the same way when comparing two different manufacturers (they differ even in product families from one manufacturer :-) ). This makes it an expert task to make other components work. So I thinks for an open source project it's a good choise to make interfacing the hardware as easy as possible. And this is archived by using stepper (dir/clk) or analog (+-10V & quadratur encoder) interface. BTW: I don't know any COMPLETE open source stack master for fieldbusses (neither classic nor ethernet). This is very special software, and a lot of work to do. It took about 3 years to write our CANOpen Master stack and to optimize it for hard realtime applications like servo control. BTW2: EthernetPowerlink provides fundamental open source software, but AFAIK it lacks the device profiles. But this may be the best starting point for a open source solution.

Re: [Emc-users] touch screen with EMC2
I have a bit of experience now with an LG 1730 touch screen monitor. It seems to work well and is not difficult to implement. I recommend using the mocca GUI (code.google.com/p/moccagui) for this type of control of EMC2. It is really good and easy to adjust all button sizes to be suitable for touch screen usage. It includes nearly all the functionality of AXIS and is being worked on actively at the moment in Germany (I have done the translations for myself on the 1240x1024 screen layout). To implement the LG touch screen in to Ubuntu 10.4 I used evtouch (xserver-xorg-input-evtouch driver). This allows an X-windows setup in the /etc/X11/xorg.conf.d directory - I cant remember the details, but it is not in the usual xorg.conf file, which have disappeared in Ub 10.4.
