Is there someone who can explain to me how to use the local parameter(s) which are used inside RexHMI Designer?

I would like to hide/unhide a window by means of a button on the screen but somehow it is not working. Should all be assigned to 'L'? When to use the curly brackets?

Has someone maybe a small example how to set this up?

The search function from the old forum is directly leading me to the new forum. Without the search function, the old forum becomes less useful...

I have a working dropdown menu on each HMI-page which is created by using some html &css. For the moment I'm dropping on every HMI-page in our project a 'Custom HTML' block on top of the page where I copy my html into the html-box on the Options tab.

However, every time I make a change I do need to copy all changes on every HMI-page in the HMI designer. Is there a way that I only have one instance that I need to change?

@cechurat said in ALB, ALBI, ALN, ALNI , .... alarm functions have no delay function:

• interactive changing of the levels*

Do you mean to set the parameters lvl1 and lvl2? Because when I do, I get the error message as described above.

Maybe I'll try the SRTF solution, could work.... or wait for a new version with the new feature

Hi Tomas,

Thanks for the swift reply, it's working like a charm..... and we learned again something

I haven't tried filtering yet, this could work but is more complex then just a simple delay (ON&OFF).
I have another related question. For the FB ALB, ALBI there is a 'men' input so you can disable the alarms. This feature is missing on the FB ALN, ALNI.

Example: if you want to monitor the oil pressure from an engine it should be possible to disable/suppress the low pressure alarm while the engine is starting up and in shutdown as well.

You have any idea how to solve this? I tried with setting parameter lvl1 to zero but this is not allowed (nor lvl 2, as described in the documentation)

While trying to create a new Subsystem to add some functionalities to an already existing alarming Function block (ALBI) I encountered problems with using declared parameters.

I declared a 'word' for the archive parameter (arc) which is used for the FB ALBI found inside the newly created Subsystem.
But once I click on the Inherit checkbox inside the ALBI FB the program throws an error and crashes (stops working and closes).

It seems that ALBI-FB is not using the value but the 'Parameter' name instead, which is an invalid value....just guessing.

Update : tested with other FB and it seems related to the 'arc' parameter, it is not accepting an inherited parameter.

Thx, looking perfect .... looking forward to this new feature.

Hi Tomas,

If you have for example a fluctuating analog signal or a signal with peaks it might happen that the alarm is triggered for a very short time. This behavior is perhaps completely normal and you don't want it to trigger an alarm if the signal is not too high/low for x seconds.
Or a low-level float in a gearbox to detect low oil level on a ship requires some delay, otherwise, it would regularly trigger an alarm when there is some bad weather ...

For boolean type signals it isn't really a problem to add some logic but to keep all function blocks for the alarming alike it would be better to implement it also for the boolean ones.

I think that it would beneficial for someone's workflow that all open .mdl files from a project are organized with tabs on top of your screen. Now I have regularly more than 10 tasks open and then it gets quite messy.
Something like the tabs for all open webpages in a web browser for example
