Re: [Cs-studio-users] Status and alarm handler severity in a BOY widget

[<tom...@di...>]

Thanks Kay. It looks like my way forward is:

* Top line symbols: Just turn them into GIFs and use the multistate symbol widget. Add support for animated gifs, and work out how to extend the multistate symbol widget to support a pulsing alarm background. 
* Middle line symbols: Add a new style to the action button which is "Rounded rectangle style", which has a pulsing alarm background when BackColor Alarm sensitive is set, and an option to bold the text on non-zero value of the PV.
* Alarm state: Use the alarm PV backend to display severity, and add an option to write to the acknowledge PV from the widget.
* Menu buttons: I managed to miss the combo widget, I'll use that...

I'll talk to ITER about the multistate symbol widget when I've dug a little deeper (the widget code mentions Fred Arnaud as the author). Who is the right contact for the PVManager alarm additions?

Thanks,
Tom Cobb

Re: [Cs-studio-users] Status and alarm handler severity in a BOY widget

[Kasemir, K. <kas...@or...>]

Hi:

I would avoid rules & linking containers.
Use a suitable widget, set the PV name, done.
Maybe adjust some properties beyond the PV name.
But don't use polylines with visibility rules, linking containers with rules and so on to create a widget that doesn't exist.
If you want a widget that doesn't exist, create that widget.
What you want to do in your first bullet is similar to the symbol widget that ITER created.
Maybe coordinate with them if additional properties of the symbol widget could allow what you want to do?

For the alarm acknowledgement, contact Eric about his PVManager additions to support alarms. Basically, he worked on displaying the alarm state from the alarm server in a PV, and allowed acknoledgement from writing to a PV.

For the menu-button-as-combo box, that might also be something that you'd have to do.
If you want the menu button to have such an option, then please consider implementing that as an option on the menu button widget.
A caveat might be that we already have some issues with the mix of native (SWT) and drawn (Draw2d) widgets. Originally, all widgets were drawn by BOY, and thus all "worked": Widgets in containers are correctly cropped when (partially) hidden, the layering is OK. With SWT-based widgets, you do get support for ' Tabbing' from widget to widget, they have the native look, but some tricks were necessary to make them fully work. Since Xihui is no longer working on this, check those widgets that use SWT controls carefully to learn about these details when you implement a combo box option for the menu button.

Re: [Cs-studio-users] CSS on the Mac

[Kasemir, K. <kas...@or...>]

Hi:

There are a ton of problems with the Eclipse 3 launcher (and thus CSS 3.x) on Mac OS X.
The SNS products contain the launcher from Eclipse 4, and http://ics-web.sns.ornl.gov/css/issues.html mentions some of the remaining issues regarding the Mac OS "Gatekeeper".

We are in the process of moving to Eclipse 4, so in about a months products from NSLSII and others should also become available based on Eclipse 4.
Until then, you might have to start those with a longish command-line as shown on the above web link, something like this:
java -XX:MaxPermSize=256m -Xms1024m -Xmx1024m -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Xdock:icon=css.app/Contents/Resources/css.icns -Dosgi.requiredJavaVersion=1.7 -jar plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar

Thanks,
Kay

Re: [Cs-studio-users] CSS on the Mac

[Carcassi, G. <car...@bn...>]

Hi Sven:

Mac build/Java 7 support is broken. There are fix/workarounds. I don't think these were implemented in the standard build, so not all sites have support for it. Kay cares more about the Mac build, so maybe the SNS version works. I'd try that.

>It would be nice if CSS could run out of the box.
Yep. A single distribution, that each site can configure, ... We have been pushing in that direction for 3 years now, with the (meager) results you see. The problem is that is much harder to make a single distribution now that each site has their own. Each contributing site has a choice: work on a common distribution while they already have their own, or work on missing features they care. Not to count the problem of coordination: in principle there should already be a "basic common" product, but I don't even see it in the download list.

[Cs-studio-users] CSS on the Mac

[Sven T. <bio...@me...>]

Dear all,

I hope I am sending this to the right audience.

I have downloaded CSS-NSLSII-macosx-3.2.16.zip from the sourceforge site and tried to run it on my Mac with Mac OS X 10.8.5 (Mountain Lion). But the tool does not seem to start properly. It shows a splash screen, then a popup which says an error has occurred, see logfile xxx. I checked that logfile, and it looks like this:

!MESSAGE Missing required bundle org.eclipse.swt_[3.6.0,4.0.0).

------------------------

... lots of other "Missing required bundle" messages follow.

Why does it not find those jar files? They are all in the plugins folder (aren't they?).
Do I need to have Eclipse installed? It looks like some Eclipse jar files are distributed with CSS so I hope Eclipse itself does not need to be installed. I only want to run CSS, not develop for it.

Then I created a shell script to try starting CSS with a java command. The site http://ics-web.sns.ornl.gov/css/issues.html helped me a bit. But this script produced other CSS errors. I set my JAVA_HOME to jre-1.7 (instead of 1.6 from the system), at least the script came a bit further but still the application failed. Finally I gave up.
Ok maybe here is a difference because I downloaded the nsls build, and the website above refers to the SNS build.

It would be nice if CSS could run out of the box. I am a software dev but with downloaded software I expect it to work right away, without having to fiddle with paths and jar files.
Could anyone post a shell script that successfully launches CSS on the Mac? That would be appreciated, as well as any other useful hint.

Best regards,
Sven

[Cs-studio-users] Status and alarm handler severity in a BOY widget

[<tom...@di...>]

Hi all,

I'm looking at how we might implement a beamline synoptic in CSS. I've attached a mock-up of what this might look like, using rules, scripts and lots of rounded rectangles. 

The bar along the top shows vacuum and beam status, including how far along the beamline the beam is getting. They have only two states: green if beam can get through, red if it can't, and the symbols change shape in case the user is colour blind. If anything in this line is clicked it brings up a more detailed overview where things can be controlled. The vacuum is grey when ok and red with pulsing alpha when not.

The icons and buttons along the middle are components on the beamline that can be moved. They have two states: grey if they are idle, green if they are moving. They also have the standard epics alarm severities: grey for ok, orange for minor, red for major and purple for disconnected. The minor and major severities also pulse the alpha channel at different frequencies in case the user is colour blind.

The bottom section is for quick access control buttons and other miscellaneous status.

So far so good, but now I am wondering how best to turn this into a maintainable screen. The current mock-up has a number of problems:
* The top line symbols are a red and a green stacked BOY Polyline drawings with visibility rules and an action to open an OPI on click. Should I turn them into PNGs and use a multistate symbol widget? Or just put the two drawings into an OPI screen complete with rules and use a linking container?
* The middle line symbols are linking containers with action to open an OPI on click. The linking container OPI file contains an image, a label, and a rounded rectangle with rules for colour and alpha. This is really a button, so should I extend the button widget with a new display type? I would also like to use these buttons in sub-screens, so it would be good to avoid having to distribute this linking container OPI with all sub-screens.
* The component state and severity come from chained calc records in an IOC. I would like to be able to acknowledge alarms from this screen, so I wonder if there is any merit in using the alarm system. Has anyone else done anything similar?
* The "Open" buttons are Menu buttons. I was expecting a way to be able to style them as combo boxes, but this seems to not be available. Is there some other way to get a native combo box with entries from an mbbo in BOY?

Thanks,
Tom Cobb

[Cs-studio-users] Observation / Bug?

[Jörn W. <j.w...@hz...>]

Hello,

I'm using CSS 3.2.15 downloaded fom SNS.
In a BOY OPI I used a Spinner widget to change a PV variable. But discussions 
with theb users of the OPI lead to the decission to use an Text Input instead. 
I converted the Spinner Widget into an Text Input Widget via the context menu.

When running this OPI, I was not ablle to change the PV value via CSS. Any 
value written to the textinput was immediately  converted to zero. I still 
could change the value of the PV via caput. After replacing the "converted" 
Text Input with a "fresh" Text Input, everything works.

This gives the impression, that the widget modify function leaves some 
parameters in the OPI file (e.g. limits) which are hidden in BOY's properties 
window, but still used by the runtime engine.

Three widgets on the same OPI behaved that way.
Has somebody else seen that behaivioure?

Kind regards,

Joern Wuestenfeld

Re: [Cs-studio-users] Scrip Parameter Problem in CSS

[Kasemir, K. <kas...@or...>]

Hi:

The key difference between versions 3.1.x and 3.2.x is the PVManager.
See http://htmlpreview.github.io/?https://github.com/ControlSystemStudio/cs-studio/blob/master/applications/plugins/org.csstudio.opibuilder/html/ChangeLog.html#3.2.9

Before, you were able to use constants like this:

1
"fred"

Now you need to use PVManager formulas like this:

=1
="fred"

Existing *.opi files are somewhat automatically translated, but that's not done if the constant is based on macros:
$(macro) could be anything: PV name, numeric constant, string constant.

So you'll have to update your *.opi that uses macros to use the new syntax for constants.

Thanks,
Kay

[Cs-studio-users] Design strategies for CSS BOY screens

[<tom...@di...>]

Hi all,

Apologies if you've already received this message via tech-talk, but it's probably more appropriate here.

We're currently evaluating CSS and BOY as an EDM replacement, and I am considering how display screens on beamlines might look in this framework.

Currently we have an EDM "Synoptic" view of the beamline, with icons that show the status of each component on the beamline. Clicking on one of these icons brings up a summary screen for the objects that make up the component (motors, temperatures, diode readings, etc.) These summary screens are mainly auto-generated from tags in the EPICS database, but a significant minority are manually created. Clicking through from one of the summary screens takes you to manually created detailed screens for that object.

All of this means that a typical desktop might look like this:
http://controls.diamond.ac.uk/downloads/other/files/EDMScreenShot.png

Multiply this by 4 monitors and 8 Linux workspaces and users have an awful lot of screen real estate to get lost in. The main synoptic typically gets buried in the background, so the users open another one, then you have multiple copies of everything and can never find what you're looking for.

Now the simplistic approach when converting to CSS BOY would be to translate every EDM screen into a BOY screen, launched in its own window. But then we aren't really solving any problems, we're just making BOY look like EDM, and it takes a lot of work to persuade eclipse not to put toolbars everywhere...

Another simple solution would be to use tabs, default action is open in current tab, with an option to open in a new tab. This solves the mess of windows, but all our EDM screens are different sizes, so if we assume a large central area for the current BOY screen, then small screens with only a couple of widgets on them mean rather a lot of wasted space.
 
So how have other sites designed their BOY screens? Are most of your opi screens similar sizes? Do you make use of the various different tear off tabs that eclipse offers you? Do you open multiple windows on multiple workspaces? Do you try to manage how the users perspective should look, or do you leave it to the users to dock their windows where they like?

Any feedback/screenshots gratefully received, anything that helps us get better at GUI design has got to be a good thing!

Thanks,

[Cs-studio-users] Xihui's new email contact

[Chen, X. <ch...@or...>]

Dear Folks,

Today is my last day at ORNL. I will be starting a new RCP developer position at RTI next week.   I'm sorry that I missed the monthly meeting this morning, because my carpool friend was late (I already had my two cars shipped to California).

It was a very joyful experience working with you guys in past years. Thank all of you for the support and encouragement! Wait, this is not the ending... I will try my best to continue working on BOY, XYGraph and o.c.swt.widgets in the future, so please keep me in the loop.

My personal email is zty...@gm...<mailto:zty...@gm...>. Should you have any questions or requests, please don't hesitate to email me or put your issue on github. I have subscribed to github using my gmail.

Cheers,
Xihui

Re: [Cs-studio-users] Can't find method java.util.Formatter.format

Hi Kay,


You are right, the issue was that. I'm newbie in Javascript, and couldn't
find any example of format() that explained that error.


Best regards and many thanks.

[Cs-studio-users] Can't find method java.util.Formatter.format

[Antonio l. <ald...@gm...>]

Dear Colleagues,

We are writting the next javascript code, embedded in a OPI button:

importPackage(Packages.org.csstudio.opibuilder.scriptUtil);
importPackage(Packages.java.lang);
importPackage(Packages.java.util);

var sb = new StringBuilder();
var f = new Formatter(sb, Locale.US);
f.flush();
var line = f.format("%4$2s %3$2s %2$2s %1$2s", "a", "b", "c", "d");


and we are getting the error that the format funtion can't find.

2013-10-18 11:56:53 ERROR: Error exists in script null
Can't find method
java.util.Formatter.format(string,string,string,string,string). (script#8)

Does somebody know the reason of this? we need the format function to give
format to some values to a string.

Thanks in advance.

[Cs-studio-users] View archived enum data

[Christoph B. <bu...@ik...>]

Hello everybody,

we are using CSS ArchiveEngine with a PostgreSQL backend. It works quite 
well for us.
The Data Browser is an adequate tool to display archived numeric time 
series data.

Is there a special tool to display archived enum data? (for example a 
table which shows in multiple rows whenever the on/off setting off a 
device changed in the past)
Of course one can display those values in the Data Browser as well, but 
it's a bit hard to read.

Greetings,
Christoph

[Cs-studio-users] Handling of initial not-yet-connected state; null vs. Exception Re: Formula in BOY >> java.lang.RuntimeException: Can't find match for function '+' and arguments [null, VInt]

[Kasemir, K. <kas...@or...>]

Hi:

All network-based PVs are initially disconnected.
On one hand, it's correct to reflect their initial disconnected state: Value is null, BOY widgets show disconnected, Data Browser plot starts with a 'No Value' indicator, alarm server sends alarm, formula has only data for some of its inputs, …

Hopefully they connect soon, so now the widgets can show the value, formulas can be evaluated, ...

Later, if the PV should disconnect because of a problem, you obviously need to see that, so it's back to BOY widgets show disconnected etc.

Still, that initial handling of newly created PVs that have no data is not very practical. As you open a new display, all BOY widgets would flicker from 'disconnected' to the connected state, log shows warnings from formulas, operators get flurry of alarms when alarm server starts, strip-chart plots start with an error, …
I think it's much more practical to have an initial grace period. For the alarm server, it simply doesn't do anything for the first 30 seconds on new PVs. Then, it would alarm if they're still disconnected.
Unclear what to do exactly for displays, since you need to display something from the start, but the impression to the user should not be "Disconnected, panic, something is very wrong" but "Well, we don't know, yet, give it 30 seconds".

On the PVManager level, maybe this can be handled by distinguishing between exceptions and null values, having guidelines how to handle them.
Exception: Problem, needs to be displayed, logged, …
The initial 'disconnected' exception, I think, is already delayed, so on a newly created PV you won't panic right away, there is a grace period.
The null value simply means: We don't know, yet. In most cases, you don't do anything until you get a non-null value.

If a channel starts, you may get null values, which you can ignore. If the channel really doesn't connect after a grace period, you get the exception, so you indicate the error.
Hopefully, you get non-null values.

If a functional channel suddenly disconnects, you get the exception and can display that right away.

Could there be a case where there's no real error, nothing that results in an exception, and still you get null values?

Thanks,
Kay

Hi Nadine,

You are doing nothing wrong: the pv for whatever reason is not connected, so it has a null value. Null handling within formulas is still not handled well because it’s not clear to me what’s the proper way to do it.

The difference is probably that probe shows you everything that goes wrong. I hope that, after a while, the function connects, and the error is cleared…

Subject: Formula in BOY - stupid question... >> java.lang.RuntimeException: Can't find match for function '+' and arguments [null, VInt]

Hi again,

I am testing the auto complete for formula in BOY and so I have a Text Update widget with PV Name:
='TEST-BST0:TANK-LEVEL'+100

And another one with:
='sim://sine'+100

When I run the OPI, I have the following error – twice:

But on the other hand, the OPI is running pretty well:

So what am I doing wrong?

[Cs-studio-users] Refreshing OPI in Runtime mode causes 'Image' widgets to "shrink" in the y-axis

[Grelle, A. L. <ag...@an...>]

Good Afternoon,


I am creating an OPI which uses the 'Image' widget to display valves and pumps to the screen. These Image widgets have a rule that displays one of two images depending on the state of the connected PV.

When initially opening an OPI file in Runtime mode or Refreshing the OPI once it has been running, the widget is 'shrunk' in the y-axis to approximately 2/3 of its intended size. If the condition is met to switch the image, the widget returns to its normal state, which persists as the PV changes and the two images are switched between. The widget is fine at this point until the entire OPI file is Refreshed, at which point it returns to its shrunken state.

Any ideas on the cause or suggestions on how to alleviate this?


Thanks,

Austin Grelle
