basic label that reads strings

[MrPike]

Is it possible to to modify the basic label to read strings from modbus thru the property settings?  I know that I can write the code to do this but was wondering if it can be a default function where i can enter the starting register and number of consecutive reads and whamo, the string displays in the basiclabel text.  I ask because i plan to use a bunch of them and want to avoid writing  the code.  Thanks.

The latest beta version of 3.99y supports strings in the Modbus driver. The address modifiers have been changed to accommodate this. You can now use an address like 40001@S10 to read 10 bytes starting at 40001 and it returns the result in the format of a string. So you can put that address in the BasicLabel's property of PLCAddressValue.


You can get the beta version from here:

That's awesome Archie!  What is the easiest way to upgrade from 3.99x?  Thank you.

Archie, I started migrating my project from 3.99x to 3.99y by adding the .vb files as existing items.  Everything went well until I got these errors.  There are a bunch more than shown.  What I noticed is all my AHMI components are now missing.  I have the drivers but no controls.  I shut VS and restarted but no luck.  How do I proceed?  Thank you

To do an upgrade:

- Download and extract the latest version
- Open the latest in Visual Studio
- In Solution Explorer right click the AdvancedHMI project and select Add->Existing Item
- Browse to your old solution
- Select one of the *.vb files that corresponds to each form (e.g. MainForm.vb)  Only select 1 at a time and repeat for each form otherwise it will not pull the associated files in with it

- Once all of the forms are imported to the new version, Build the solution
- You may get a few errors in places where property names have changed. Double click each error and manually correct

I recommend putting everything unique to you in a separate folder.  It makes upgrading A LOT easier.

I worked thru this.  I had followed the steps you outlined but I think the issue came about when I deleted your mainform to add my mainform.  The entire .dll file for the drivers was missing.  I copied the .dll file from a fresh copy and it cleared most of my errors.  BTW, the Modbus string read feature works like a champ in the latest version.  Thank you.
