Off topic / Re: who invented plus+1 as programming language?
« Last post by Tor on Today at 10:30:51 AM »
Hello again.

This is what I got.

PLUS+1 as a programming language has its roots from late 1980s.
Göran Nilsson was the one who invented the data flow diagram programming language that has evolved into PLUS+1 GUIDE.
Göran was one of the co-owners of an electronic company (NOB Electronic) in Älmhult Sweden, which was later aquired by Danfoss in 2000.
PLUS+1 GUIDE was released at BAUMA Germany April 2004.
The development of the PLUS+1 Tools is still driven from Danfoss Power Solutions AB, Älmhult Sweden.

Hello,

Great question.
I have sent the question to a person how should know the story of the PLUS+1 software, and I hope we can get an exciting story. But it may take a while, so be patient.


Have a nice day.

PLUS+1 Service Tool / Re: ServiceTool 2022.4.6

Hello,

Yes, the "Indicated changed value" is reported as a bug (CQ: P100006548).
The difference between Online and Offline mode is nothing I have seen or heard about.  I will add that as well.

Don't hesitate to report these things to the PLUS+1 Helpdesk: https://danfoss.my.salesforce-sites.com/dpscustomersupport
Then the issues will be reported a little quicker.

Thanks for letting us know.

General controls / Re: Test Tool and H1_EDC_Ang_Snsr Block

Thanks for replying again Matt,  I've been working on another project in January so this is the first chance I've had to come back to this.

I've included screenshots of the test page, and the In, Expected and Actual values from the test table.

The test table calibrates the block to the point where status and statexp are zero, but then when I give it a signal power value that takes my input ratio to 100% the block doesn't output a fault signal after the fault detection time elapses (1000ms).

Code sharing / Re: String Concatenate C Code POU
« Last post by AlbertMilani on January 28, 2023, 03:24:37 AM »
This seems to be working great except if I have any other error, I also get this warning:
Code: [Select]
*** WARNING 447:1105 *** [PLC2C] PLC Code Compilation Warning {String of default length will be returned,
which may be less than expected length. Save expression into temporary variable to avoid uncertainty.}
Line: [ 1 ] in implementation of StrConcat_Native
I changed the code to do what the warning recommended, 'Save expression into temporary variable to avoid uncertainty" and that warning doesn't happen anymore.

You'll want to use the PLUS+1 Update Center and find it in there.  I also look on the website first often times, and when I can't find it there the Helpdesk always says to use the Update Center software to find it.  The Update Center comes with the GUIDE platform.

Controllers / Re: SC050 examples
« Last post by macbahi on January 20, 2023, 03:12:51 PM »
Hello Tor

Thank you very much sir.

It's a shame because I thought the controller was redundant.

Now please if an output is enabled on the primary but I don't want it to be conditioned on the secondary. I can do False DisableOutput. If there is a problem, can the primary do its safety job despite the secondary output Disableoutput being forced to False.

Please my last question: is it possible to do the test. In other words, how to be convinced that SIL2 is done.

Thanks
Cordially
