#### Curt Wuollet

In this period of deathly silence, I thought I would take the opportunity to ask a few questions of the hundreds of lurkers on the list. The project is kinda slow and I know many of you would like to see something happening. I am working on some more exposure and it's kinda embarrasing that the posts are down to a trickle. Answers would be appreciated, can be on or off list. Those of you who have been around a while know that I take this feedback seriously. 1. Project is worth persuing Y/N. 2. What are the barriers to participation? 3. How many intend to contribute? 4. How can we facilitate that? 5. Are the principles / social goals inportant? 6. What would you like to see? 7 How can we get this thing moving?

Hi Curt, > 1. Project is worth persuing Y/N. Yes, absolutely. > 2. What are the barriers to participation? In my case, there are three barriers: time, time, and time. I would guess that's true for many people -- they have a genuine interest in the LinuxPLC, but feel constrained by their available time to contribute. I would also guess that there are any number of folks who are interested in using a LinuxPLC who don't have (or don't have confidence in) C coding skills. Finally, it may be that participation is hindered by nasty employment agreements about "everything you do is owned by The Company." > 3. How many intend to contribute? I hope to contribute, at least a little bit. > 4. How can we facilitate that? Figure out a way for me to magically have more Free Time. :^) > 5. Are the principles / social goals inportant? Yes, very. > 6. What would you like to see? Not having to buy proprietary hardware and software to do controls work. > 7. How can we get this thing moving? Good question. I think having to access the code via CVS is a barrier. Having a "Download" link on the linuxplc.org homepage to a packaged release would ease participation, giving an easier entry for people who aren't familiar with CVS. Getting into a cycle of released baselines would help.

#### Marco Silvestri

Hi to all well, I'm a lurker because I am a Linux user and work with Siemens S7, so I'm interested both in linux and PLC. In order to participate, first of all I need more information (does exist a FAQ?): What are the next goals of the project? What has been done until today? Are there some docs? How can I have a "resume" of the situation? The very main difficult for me is tha in the list you're talking about one or another detail, but I can't have a complete image. Hope this can help. Many thanks, Marco P.S.: I can write code in C, and also give info about S7. ) _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc

1. Project is worth pursuing Y/N. Definitely. Don't give up. 2. What are the barriers to participation? Time and skills. 3. How many intend to contribute? I am contributing quietly. Am working on a web based HMI that is progressing well. Should have something to post soon. The final step on this project will involve some C programming. After I am done, maybe I will have enough confidence to help out with the linuxplc project. 4. How can we facilitate that? Would it be possible to have my HMI work accessible through the linuxplc site when it is ready? 5. Are the principles / social goals important? Absolutely! 6. What would you like to see? Expand out to include encompass all things in control, ie; process control, machine control, HMI, etc. 7 How can we get this thing moving? Get College engineering departments/graduate students involved. Join forces with other efforts out their. Get the word out there. ( You already mentioned that one) _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc

Maybe a thoughtfully worded "open letter" to employers explaining why participation in the project is good for all and politely asking for some wiggle room might help. Even if it doesn't it would be good PR and a non confrontational way for people to approach their management. I would be happy to answer questions or take the heat.off of volunteers. I can handle this if no one else volunteers. <clip> > > 7. How can we get this thing moving? > > Good question. I think having to access the code via CVS > is a barrier. I agree. although this is common for Linux and UNIX IS shops, It is a pain if you don't know it. We need a volunteer with a reliable connection to make a tarball occasionally. > Having a "Download" link on the linuxplc.org > homepage to a packaged release would ease participation, giving > an easier entry for people who aren't familiar with CVS. > Getting into a cycle of released baselines would help. Having a packaged release would be a good thing We'll get there.

Hello everyone, Now here's a good idea: >> Maybe a thoughtfully worded "open letter" to employers >> explaining why participation in the project is good for all >> and politely asking for some wiggle room might help. >> Even if it doesn't it would be good PR and a non confrontational >> way for people to approach their management. I would be happy >> to answer questions or take the heat.off of volunteers. I can >> handle this if no one else volunteers. I'd like to help you do that -- I'll pass it by some senior corporate people for their insight; we'll get input from the list and Curt's approval. Then I'll help you put out a press release to 30+ industry magazines: "LinuxPLC newsgroup submits open letter to CEO's about the benefits of participating in open source software development..." How does that sound?

#### Curt Wuollet

We have a volunteer! I don't know about the press release, I'll have to think about that.. Linux usually creeps into organizations from the bottom up. Publicity may let people solidify a policy rather than deal with a request from a valued employee. I think the latter may be more successful. Perry, you're working to get on the same "sh*t lists" I'm on. congratulations.

1. Yes 2. As everybody else says, time, time and time, I hope there is a fair chance of change (since I now actually can make the plans I would have needed the last 7 months) Another problem for me is that I am relatively new to linux (and then I have had it at home for a year or so), but I know that there is an awful lot of things I don't know 3. I am interested, time will still be a limited resource 4. Well... I can perhaps manage that myself now... http://w1.451.telia.com/~u45102278/QSplan.htm 5. I think so 6. I am not sure I understand what you are asking about 7. Well, you see, if there is enough snow on a hill, and the weather conditions are right - then it is just a matter of putting enough snow in one place and - there is the avalanche So it is just to go on... some day if enough people keep going. Look at linux itself, it has just begun to really move... ---------------------------------------- P&L, Innovation in training Box 252, S-281 23 H{ssleholm SWEDEN Tel: +46 451 49 460, Fax: +46 451 89 833 E-mail: [email protected] Internet: http://www.pol.se/ ---------------------------------------- _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc

Curt: 1 The project is definitely worth pursuing. 2 Not 100% sure as to how "I" can help. 3 I would like to. 4 Probable need to figure out how I can help. 5 ? You will have to expand on this statement. 6 Typically one or more people have to drive the project. My background: I design, build, program controls for test & production equipment. Currently only for in house use at the company I work for. My "C" programming experience has been at the control level "no operating system" or under "dos". I'm relatively new to Linux and am learning. The last project completed at work used "dos" and "qb4.5". Don't ask, this was dictated by people higher up that have no idea of controls. Modbus (asc & rtu) and USS (siemens inverters) protocols were used in this particular application. Written in QB 4.5 on an embedded biscuit type pc. Languages I've used - about 6 versions of basic, c, asm, MMI packages WonderWare, Genie PLCs omron 200 series, ab Slick series, modicon 311 & 984 series SBCs ZWorld, Sixnet etc. a host of various other ascii based devices experienced in writing drivers for numerous devices and protocols (not under Linux though) I do have access to a host of devices - serial based High Limit Controllers, Inverters, PLCs, computers etc. If you have any ideas let me know. If equipment or ? is needed I may be able to get the company I work for involved in some manner. jeff _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc

My answers may be dated as I haven't gone to the home page recently, but I felt I had to answer to add credence that there is life "out here" > 1. Project is worth persuing Y/N. Yes. I think most of us feel that if it weren't worth persuing it would also not be worth following > 2. What are the barriers to participation? Problems in contribution: Time. Possible Conflicts of Interest. Learning curve of people new to the development model. Problems in project: Trying to be all things to all people. Lack of an implementation roadmap. > 3. How many intend to contribute? I hope most people involved in such an endeavor intend to contribute when they see an opening they can fill. Any one who expects to "get something out of it" should "put something into it". > 4. How can we facilitate that? See question 6 > 5. Are the principles / social goals inportant? I think so. I'm tired of getting locked into a technology or being forced to make changes in my equipment just because the old stuff is no longer available. Nor do I want to pay $5000 for$100 worth of additional functionality. > 6. What would you like to see? Create a wish list of critical pieces that are holding back a proof of concept implementation in a virtual environment. A newsgroup so different conversation threads can be stored and reviewed so we needn't rehash decisions. > 7 How can we get this thing moving? This list of questions should help. _______________________________________________ LinuxPLC mailing list [email protected] http://linuxplc.org/mailman/listinfo/linuxplc

Yes the project is worth persuing. Only about a dozen people responded which isn't a very large activist contingent. > > 2. What are the barriers to participation? Most people, myself included, are suffering from the lack of time. Just think what we could get done with a company sponsoring one FTE or 10 companies each sponsoring .1 FTE or ? Think about it, even just one full time programmer or equivalent would be a lot of push. Split up between say, 10 sponsoring companies, this would be enormous return on investment. I know there are places that mate up companies wanting OSS with developers, I wonder if there is the inverse? WANTED: Ten companies to make a small investment that will make a bigger impact on the industry that anything else they can do. Will return a new market for goods and services far beyond investment. Risky, but the minimum return will be a free alternative automation platform with intangibles like goodwill and excellent PR. Must forgo direct commercialism and play by OSS rules. > 3. How many intend to contribute? I assume about that same dozen, but I'd love to be proven wrong. > 4. How can we facilitate that? This is the tough one, with only a little time to spare, I can't even directly contribute. We have to find some way to make it easier. I could use some more suggestions. > 5. Are the principles / social goals inportant? This puzzled quite a few people. To me it means: Free, Truly Open, GPL'd and publicly owned. Lesser goals are that it be done the Linux way and be as accessable as possible so that we open participation to as many as we can. It must also be legally unencumbered and vendor neutral. There are quite a few other ideals I feel strongly about, but that's a start. > 6. What would you like to see? Broader base of participation. > > 7 How can we get this thing moving? More people with more burning desire to see it happen.

Curt: Since your original posting I have checked with the VP of Engineering in my company about this project. He did express interest in the project and had numerous questions. I simply let him read the Puffin PLC intro and specs. One of his first questions was, what is in it for us. My reply - short term "nothing". Long term a control platform that does not cost an arm and a leg for each installation. I also mentioned he may want to consider the PR that could be "had" by association with this type of project. He has since said he has an interest and to keep him up to date. jeff

Hi Jeff Great! You might also casually mention that being involved in Linux projects has been a powerful recruiting tool. We have been able to hire people that we probably couldn't have because they want to work with Linux or don't want to work with Microsoft. These "zealots" have been excellent engineers and highly comitted. Check out the ROI there, we get rid of a whole bunch of problems and attract people who would ignore us for free. It may sound like a small thing but, having the best people is life or death for a small company.
