Support Questions / Re: ImageDisplayByValue

1. ImageDisplayByValue property set Autosize to False.
2. You can change size of image in the property of ImageList.

This is incorrect! Image size is limited to 255x255

As Godra said, take some time and learn.
I noticed that you just signed up and immediately asked questions.
In addition, the function of adding a new form is about Microsoft Visual Studio, not AAHMI.
I did a search and there are several links that talk about adding forms.

OK, you were not inspired by the 2015 movie.
I know enough about the dragonfly.

Did you know when the dragonfly is flying low, it means it's about to rain and when it's flying higher, it means it's sunny?

Dragonfly!  The animated series or the scary one?

Have you checked the actual string?

LOL, you realized it's for Codesys PLC, not Rockwell source.

I would trust this guy Ron Beaufort: https://www.plctalk.net/qanda/showthread.php?t=59105

Plus, a string contains ASCII code from 0-255., make more sense than -128-127.

Godra,  I was only testing out its capability. You are way far ahead of me.

If you look at the tag in the PLC, you will see that that the data array index start at 0. So If a custom string length of 20, then you need to have 20-1=19.

Another thing you need to look at is the data type in the PLC is SINT. What is SINT?  is it really equivalent to SByte?
SINT is short integer(0 to255) not signed integer, a SByte is Signed Byte(-128 to 127)

Aye, your issue was not about the size of the UDT, but rather in the string tag.  Now you can concentrate on finding the fix for it.

Is an easier way to read the UDT tags with AAHMI.

My recent experience with node-red is blowing me away with how easy it is to read/subscribe tags including UDT tags.

First, the Tag Browser brings up all tags in the processor, then clicking on the tag that you want to read/subscribe will get it into the Tag list with proper data type automatically defined.


In the 1st screenshot, DTCurrent is a UDT tag that contains date time info  AND a custom string length of 20. The FreeRunning tag is a TIMER. As you can see, in the node-red they are STRUCT type.


In the 2nd screenshot, showing all the atomic data type and the debug data from the two tags



The ethernet driver module that I use is the 'node-red-contrib-cip-st-ethernet-ip'  and on Github:

I normally approach the issue by simplifying,  dividing and conquering.

Can you verify that you can read a simple tag with your custom length of 4?

That's probably why.  My PLC is a 5370.
Such messy string definition , for ex. STRING_8 can contains up to 24 chars.

I was able to import it into a L330ERMS2, rework the UDT to v2.  then import to my PLC.
It took less than a second to read all tags.
see picture & attached v2.

From 4.0 which released back in 2010 to 8.0 in 2023 . That's a really big jump.

Will it run straight in pi without installing mono?

No good , wont import.

Error: Object does not exist.
Import failed - 1 error(s), 0 warning(s) - No changes were made to the project

STRING_16 is built in. No need to include
