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:
Then the issues will be reported a little quicker.

Thanks for letting us know.

Anyone else seeing this problem in the latest ServiceTool?

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

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

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.

No, you cannot use the secondary processor as a redundant unit if the first one breaks down. If you look at the template for the secondary you only have "DisableOutput" as a signal out.
What you can do is to have your own code in the secondary processor to monitor specific safety functions that can shut down the output.  But again, I recommend you to read the safety manual before doing so.

Have a nice day.

Hello Tor,

Thank you very much for your information:
The secondary processor is there to check that the first processor is working correct (to achieve SIL2) and shut down the outputs if it's not. This is already done in the background, without you adding any logic.

But please If I want use the secondary as redundant processor, Is it possible to do that?
As example if there is any problem with an output in the primary processor, normally the controller will switch to the secondary processor to keep the output available.

Thanks in advance for your help

With best regards
