Can I generate DCS, PLC and SCADA application software with
ControlDraw?
|
This seems to be what everyone asks when they see what
ControlDraw can do. The answer is No. Why not?
CD is aimed at the specifications - the requirement not the software
itself. Prospective design and validation.
The boundaries between design and programming are narrow, in fact some
people say that the first statement of the requirements is also the
first part of the software design. At present there is no equivalent in
commercial control systems to ANSII C++ for PC's. So the process of
making CD generate code (it could) is not worthwhile, especially as most
commercial control systems can be programmed quickly given good
design information in the Functional Specification.
ControlDraw can of course be configured to produce for example a tag
database for a DCS or SCADA, and many of the other electronic lists that
help when programming.

Is ControlDraw
S88 compliant?
|
First, there is no such thing as S88 compliant. (maybe
some Google users think there is)
However ControlDraw fully supports the S88 physical and procedural models, including
the flexible aspects such as recursion (Control modules in Control modules, phases in phases etc).
Starting Classes for each type of S88 object are provided, and users can configure specifications to match their own interpretation of S88 or other methodologies.
|
|
How much does ControlDraw cost?
|
The Print and review program is free. So,
if you are developing a model and your client needs to see and
comment on the model your client does not need to purchase the software.
Licenses for commercial use of ControlDraw cost from GBP1600 for 2
users, with discounts for larger teams. If you would like a
quotation then please send a request for proposal, including some information on your company if you would.
Licenses for educational organisations may be obtained for nominal
costs by agreement.
Low cost 'Partnership' licenses may be available for some ControlDraw
model developers.
ControlDraw may be the best tool you can find, but it requires more
than you just buying a tool to move to the state of the art.

Can ControlDraw import P&ID's?
|
ControlDraw can import most types of Windows pictures, into single
objects or as a diagram background. So you can if you want put a P&ID into the background of a diagram
(using Paste Special) and then overlay - place objects on the diagram.
But, for good reasons, ControlDraw is not P&ID based:
1 P&ID's have a slow development cycle and are
almost always out of date apart from the
marked up paper one the process engineer has.
2 P&ID standards are very variable from company to company, what
is shown and the numbering systems vary enormously
3 P&ID's are often very inaccurate, frequently missing details of
control loops, contents of process packages etc.
4 P&ID's are not object oriented in any way. For example where
are several identical units (ie one Unit Object) they still mostly draw
one P&ID for each. If you are lucky. Sometimes
you will find more than one unit (say 2 and a half) on one P&ID or
one unit defined on 2 or more P&ID's!
5 The instrument database behind typical P&ID software is
generally very inaccurate. And the text in them is often useless (we
know FT means Flow Transmitter, we want to know what the flow is doing!)
6 P&ID's are not designed for operational purposes, for example
they >are full of clutter such as nozzle sizes that are not relevant
to the control, or even the plant operators. They are usually a poor
basis for control system graphics.
7 P&ID's totally fail to represent procedural functions
However, they are still useful, especially if they have a
database behind them, such as with InTools.
ControlDraw can draw upon that to greatly accelerate model development.

Yes, Lists in Excel can be pasted into diagrams as symbols, and as
text into objects, and even as a complete set of of symbols and diagrams
(new)
In fact this applies to any list in the clipboard,
such as an from Access or a Word table. So if you have your P&ID as
a background and can query the P&ID database to get a list of the
valves on the P&ID you can quickly put the valves on the diagram.
Then move them to their positions manually, or even position them
automatically if the list contains size and position data..

How does ControlDraw track version changes?
|
It does this in five ways:
By recording version information for each object.
By keeping a history of major changes
By using the Diagram Change Tracking function and
By comparing two models
And you can add manual notes to the history
|
|
Can ControlDraw keep an Audit Trail
|
An Audit Trail is more than just a version history. Yes ControlDraw
can help you to maintain an Audit Trail, provided you include the
necessary information in your model. The standard classes include
Document references which you can use to point to the source documents.
Each ControlDraw object has a unique identity in the model, making it
possible to track the history of each object, through the archive.
How much you keep in the archive is up to you. The internal archive in a
model includes major event such as adding a diagram. The external
archive is your collection of backup files, made using the ControlDraw
publish and backup functions.

What does 'Single Diagram Style' do on the Windows menu?
|
First it fixes the list of diagrams on the left of the workspace, and
sizes the diagram to fit the space between the list and the right hand
side of the workspace When this is selected you only have to click once
on the list to open a diagram. If you do not select this then you may
have several diagram opens at once, this is useful for working on a
collection of similar or related diagrams.
|
|
Is the ControlDraw database 'open'?
|
The CD model is an Access database. It includes reports and forms
that you can use if you open the model in Access itself. There is no
password, even in the evaluation version. This means that you can add
your own expertise to the standard capabilities of CD.
Sometimes it is useful to use a Front End database. For example a
database for the equipment parameters, or the IO list. ControlDraw is
developing a front end wizard for creating such databases.
|
|
How many users can work on a model'?
|
Depending on what actions the users are carrying out, up to 10 before
performance slows significantly. 4 or 5 working on diagrams, some more
printing and adding data. Certain actions are best done by a single
user, and ControlDraw prompts in such cases.
You can also split a project into a number of linked models with a
shared Reference Model to handle
bigger projects. See below.
|
|
Can ControlDraw use SQL Server or Oracle databases
|
At present no, however this does not mean that you cannot handle
large projects with many users. ControlDraw provides an alternative
solution using multiple synchronised models. Each team builds a model
for their area of responsibility. Using the Reference model capability
of ControlDraw each can use a common collection of classes and diagrams,
which are defined in a single Reference Model. You can see more about
reference models Here.

|
How do I get Started with ControlDraw?
|
One way is to use a Start Template.
The S88 starter templates includes physical and procedural classes, an
outline structure and sample S88 objects.
'To Do' notes to guide you through the production of your model.
The evaluation version includes a basic S88 starter. Purchasers can
obtain more templates, more classes and predefined test sheets.
You can also download (right click) a PDF version of the Manual
(18Mb.)
Purchasers get a copy of the ControlDraw CD. This includes additional
start templates, presentations, training material and sample models.

How big an organisation is ControlDraw?
|
We are a dedicated team of 1 with a global network of consultants, associates
and trusted colleagues. It is a one man global company, with friends and
users round the world. It does not make
hardware and it does not take risks.
It has no problems with internal communications, no debts and no cash
flow problems. And the most efficient software development process
known.
|
|
Who would support us if ControlDraw went out of business.
|
ControlDraw Ltd runs a low risk business so it is not likely.
ControlDraw Ltd has outlasted one of it's competitors and the other appears
to be on the way out. It was there before them too.
ControlDraw software would not stop working.
Key clients have copies
of the source code.
With hundreds of users worldwide, you will be able to find help.
|
|
Can I buy a better ( or even nearly as good) product from a BIG COMPANY?
|
ControlDraw Ltd has researched this extensively. There is nothing
comparable. Maybe you are convinced that UML
can handle process control but ControlDraw Ltd would disagree.
The fact that ControlDraw Ltd is small is an advantage to you. For
example, license costs are low due to low overheads, product
developments can be made rapidly to your specific requirements
etc.
|
|
Can ControlDraw work with version 1 models?
|
You can import these into CD2.
You would not want to send them back.
|
|
Can I develop something myself?
|
Yes, if you have a lot of time.
ControlDraw development has taken about 20,000 hours plus $thousands
on tools and components. And with a highly efficient software development
model.
To
develop something comparable just for your own in-house use would take
10,000 hrs plus, even with the latest software tools and a great team.
If you already have something then most likely we can import from or
link to it .
