SCADA Mailing list
Advertise on this site
An expert is a person who
avoids small errors while
sweeping on to the
grand fallacy. "
The SCADA mailing list currently has around 800 email addresses subscribed. Many of these addresses are company email distribution lists which rebroadcast the SCADA mailing list in the company internal e-mail system, and therefore the SCADA mailing list reaches an estimated 4000 people.
How to subscribe
To subscribe send a message to email@example.com with anything in the subject.
To get a list of instructions send a message to firstname.lastname@example.org with help in the subject of the message.
To unsubscribe send a message to email@example.com with unsubscribe in the subject of the message.
The mailing list is maintained using the Smartlist software package. This package has inbuilt checks to help prevent mail explosions, and we hope that it is successful in preventing this. It also detects attempts to post to the without subscribing, and automatically forwards these posts to me (Ian Wiese). If these messages are related to SCADA I will forward them to the list. It will check for administrative requests posted to the list and has some success with these. But don't expect that a request to the list asking "get me off" will be detected!.Click here to go back to the top
Purpose of list
The SCADA industry is characterised by the lack of adherence to standards. It is virtually impossible to achieve interoperability of equipment from different suppliers without special drivers and interfaces.
Standards do exist, but they are not complete. Where they exist they cover components of SCADA systems. Different vendors couple the standards together in different ways.
There have been many specifications produced which demanded adherence to specific internationally accepted standards, but there is no general acceptance of a subset of standards that should be used in any given application.
This is an industry problem. It can be solved but only by an industry wide approach to demand interoperability of equipment, especially with field Remote Terminal Units. It is surprising how few standards are required to achieve interoperability.
This mailing list has been started as a forum to allow exchange of information regarding SCADA, and to discuss standards in the SCADA industry, with the aim to achieving acceptance of standards that will achieve interoperability of equipment as a minimum.
New subscribers - please introduce yourself to the list with a short (or even long ) message describing yourself, your company, etc. Anything you wish.
Finally this list started as an attempt to promote standards. Topics of general interest to the SCADA community are welcome. The charter of the mailing list will be updated to reflect the input to the list!
SCADA vendors may use the list to give a summary of new
projects that have been won, including a brief description of
relevant points. The list is interested in hearing from vendors about new
products, or features incorporated in RTUs, communications networks and
SCADA hosts. This is intended to give members information about current
trends in the marketplace. Try to make the postings informative to a
technical audience. The organisers of trade shows and conferences
associated with SCADA are encouraged to provide information both before
and after the show ( the presenters are also encouraged to provide copies
of their papers to the list). Vendors are encouraged to regularly provide
a summary of new jobs won

SCADA Maillist FAQ and Guidelines
The purpose of the maillist "firstname.lastname@example.org" is to provide
a non-commercial forum for the discussion of SCADA topics, including
but not limited to promotion of standards in the SCADA industry. It
is administered by Ian Wiese (email@example.com).
IMPORTANT - IF YOU READ NOTHING ELSE PLEASE READ THIS
You are encouraged to use your email program (eg Pegasus, Eudora etc) to create a folder called "subscriptions" or something similar. Move this mail message to this folder and leave it there. Whenever you join any mail list save the instructions you get when subscribing to this folder. Now whenever you wish to leave a mail list, you will be able to find the instructions on how to leave.
1. PLEASE POST MESSAGES! Only a small percentage of subscribers to any mailing list participate. Unless subscribers actively participate the maillist will become silent and pointless. If you post a request for information, please try to give something back to the mailing list by summarising all the replies and posting the summary back to the list.
2. Please post thoughtfully. A considered post or response will generate considered replies, and valuable discussion could follow.
3. Try to keep arguments on a technical or business level, not on a personal level.
4. Please sign your message.
5. Remember firstname.lastname@example.org is the entire list. Be careful not to post personal communications to the list inadvertently. It may embarrass you.
6. You are encouraged to actively promote the existence of the maillist eg on USENET, amongst your colleagues, etc.
7. You are encouraged to use your email program (eg Pegasus, Eudora etc) to create a folder called "subscriptions" or something similar. Move this mail message to this folder and leave it there. Whenever you join any mail list save the instructions you get when subscribing to this folder. Now whenever you wish to leave a mail list, you will be able to find the instructions on how to leave.
8. Mail addressed to email@example.com is automatically forwarded to over 4000 people who receive the mail sent to the list. When you receive mail from the list, you will find that you can reply to the mail in your email program by using the "reply" feature of your email program.
The scada mailing list is set up so that replies go back to the list (ie to firstname.lastname@example.org) automatically. This is done to promote discussion on the list, rather than to have a posting generate a lot of private correspondence off the list. In this way everyone benefits from the discussion, and different points of view can be represented.
Sometimes this may not be what you intend. For example if someone posts a job opportunity on the list, and you responded with your CV, you may not want 1200 people (including your employer) to be aware that you are looking for alternative employment. In these cases you must be careful to ensure that your email is sent to the address of the person who originally posted the message, rather than to email@example.com.
Experienced Internet users will understand these concepts, but if
anyone has any problem understanding, please feel free to contact me
directly at firstname.lastname@example.org (NOT email@example.com!)
FAQ (Frequently Asked Questions)
1. How do I post a message to the list?Send your message to firstname.lastname@example.org. The list is unmoderated and all messages are sent to the list
2. How do I subscribe to the list?To subscribe send a message to email@example.com with
in the subject.
3. How do I get help?To get a list of instructions send a message to firstname.lastname@example.org with help in the subject of the message.
If this does not help, email email@example.com with your request.
4. How do I unsubscribe from the list?To unsubscribe send a message to firstname.lastname@example.org with unsubscribe in the subject of the message.
5. Some unmoderated mailing lists create "mail explosions". Will this occur with the scada list?The mailing list is maintained using the Smartlist software package. This package has inbuilt checks to help prevent mail explosions, and we hope that it is successful in preventing this. It also detects attempts to post to the without subscribing, and bounces these messages to the list administrator. It will check for administrative requests posted to the list and has some success with these. But don't expect that a request to the list asking "get me off" will be detected automatically. Your message will go to everyone on the list, and although the administrator will probably see this and remove you manually, this is not the way to leave. It will probably annoy a large number of people, some of whom will send you impolite email.
5. Who do I contact for help?The list is administered by Ian Wiese. You may contact him at email@example.com for help regarding the list, or on any (scada-related?) topic, or just to say hello.
6. What do I do if a "mail explosion" occurs.This has only occurred once since we changed to Smartlist. But if it were to occur, do not email to the list complaining. This aggravates the problem. It is probably being worked on. But if you are being inconvenienced, unsubscribe temporarily. And wait a few days before subscribing again. It is probably easiest just to delete the mail from your inbox.
If you want to complain, or just ask what is happening to solve the problem, email Ian Wiese (firstname.lastname@example.org), not the list.
7. Who may join the list?Anyone with an interest in the topics of the list may join. We invite and welcome members of all companies and academic institutions, including researchers, end users, integrators, and suppliers, to join and actively participate.
8. What is the purpose of the list?The SCADA mailing list was commenced initially to promote discussion of standards in the SCADA industry, but any topics related to SCADA and automation are acceptable. The SCADA industry is characterised by the lack of consistent adherence to standards. It is virtually impossible to achieve interoperability of equipment from different suppliers without special drivers and interfaces.
Standards do exist, but they are not complete. Where they exist they cover components of SCADA systems. Different vendors couple the standards together in different ways. There have been many specifications produced which demanded adherence to specific internationally accepted standards, but there is no general acceptance of a subset of standards that should be used in any given application. This is an industry problem. It can be solved but only by an industry wide approach to demand interoperability of equipment, especially with field Remote Terminal Units. It is surprising how few standards are required to achieve interoperability.
9. I am getting two (or more) copies of all mail. Help.This occurs because you have joined twice under different email addresses. If you have a work and a home email account, you may have joined under one email account at each. Examine the duplicates and note the email addresses. Unsubscribe one of them.
10. If I note some postings that are inappropriate (eg off topic, of a commercial nature etc) should I reply?You could, but normally the administrator of the list will contact the offender in private (ie off the list). Better to contact email@example.com and let him know your concerns. This avoids "flame wars". Or email the offender directly if you wish.
11. Can I help or contribute to the FAQ?Email firstname.lastname@example.org with any suggestions.
12. How often is the FAQ posted to the list?In future approximately monthly.
13. Is spam (or mass email mailing) distributed on the list?This is actively discouraged. Anyone using the list for these purposes will be removed from the list, and the postmaster at the person's address will be notified of this behaviour.
The Smartlist software used to administer the list detects some spam attempts eg those with no valid reply to address. Some spam mailings were posted to the list, and subsequent to this the facility whereby anyone posting to the list was automatically subscribed was deactivated to make this impossible.
14. Help. I can't seem to post to the list.To prevent spam messages being posted, the list now requires that all postings to the list be from subscribed members. This means your reply-to address when posting must exactly match the address you are subscribed under. If you have difficulty, email email@example.com. Note this facility in the past often caused people to be inadvertently subscribed twice.
15. Is there a digest or journal form of the list.Currently no. There are three reasons.
First the digest takes a lot of disc space, and my ISP charges heavily for this. This is always going to be a show stopper, unless a sponsor is forthcoming.
Second, I have found it takes some effort to administer.
The third reason is that such a digest is indexable by the Search engines, and by people preparing bulk email address lists. The issues of privacy, copyright of the material, and so on are not trivial, and I have not yet decided to embrace them by creating a digest.
16. Can I use the list for commercial purposes?Blatant advertising is frowned on in most mailing lists as it is unsolicited, and the recipient has no choice but to receive the advertisement. However it is normal practice to include your company affiliation in your signature file (at the end of the message). The best advertising is to participate in the discussions and contribute. The are many consultants who have won a lot of work through their contributions on the list. This is a win win situation - it helps those who need answers, and it helps you.
This matter has been discussed by the members of the list. The consensus has been that notice of tenders, job offers, and requests for consulting work are appropriate (a service to the subscribers). Commercial announcements are not.
To help resolve this I have provided a SCADA bulletin board. It provides a forum for more commercial announcements than a mailing list does. Appropriate postings to this bulletin board are items of a 'news' nature such as announcements of new product or services ,company news releases, coming events, training courses offered, employment opportunities, announcements of tenders and so on. To access the bulletin board, go to here. You are encouraged to use this bulletin board.
You may also post employment opportunities or resumes.
Further information on SCADA and links to firms in the SCADA industry are available on Ian Wiese's SCADA pages. You may be listed on these pages by clicking here. That forum is more suited for more permanent listings. ie to announce a new product or service, use this bulletin board. For a statement such as "XYZ SCADA CO specialises in ..." use those SCADA pages. For general interactive discussion, requests for information, discussion of standards, then use the SCADA mailing list.
17. What is the "gospel" in firstname.lastname@example.org for?My ISP names all his computers after music styles eg gospel, opera, jazz etc. The mailing list was hosted on gospel.iinet.net.au for many years, and the name stuck.
