Are you using v3.99x or 3.99y ?

How are you reading data in the code? Read or BeginRead? How frequently are you reading?

Support Questions / Re: how to deal withe many MODBUS devices on the same Com Port ?

« on: February 28, 2024, 08:44:13 AM »

Hi Archie,
I have tested the driver with two devices connected via a usb-Rs485 converter with polling time 100ms and time out 300;
the stable 3.99x version works correctly,
the new version (3.99xbeta4), on the other hand, always generates TimeOut errors on the controls.

This is on the list to be looked into.

You can use the PLCAddressAhighlight property to change the color. Put the same address as used in PLCAddressEnabled

The easiest way to do this is to use a DataSubscriber2 to watch all the variables. Then in the Datasubscriber2 code set the Visible property of the BasicButton

The IPAddress you checked, was that in the editing of the GroupedObject? Do you get an error in the BasicLabel on the grouped object?

Support Questions / Re: Modbus 16bit addresses Read and hold value and display value in set time

Looks like you are using VB syntax in a c# program. c# is going to be stricter with case sensitivity and type conversions.

Your code would look something more like this:

            label4.Text = (int.Parse(label3.Text) - int.Parse(BasicLabel1.Text)).ToString();

Only the live value should be a BasicLabel. The other two will be updated via code, so they should only be of type Label.

- From the toolbox, add a Timer to the form
- Set the interval property to the time you want in milliseconds
- Set Enabled to True
- Double click the timer to get back to code
- Add code similar to this:

Code: [Select]

Try
  Label1.Text=BasicLabel1.Text
  Label2.Text=Label1.Text - BasicLabel1.Text
Catch ex as exception
  Label2.Text=ex.message
End Try

I checked the code and it will use function code 6 if there is only a single register to read.

AdvancedHMI uses function code 3 to read 16 bit registers and function code 16 to write them.

Normally you use addresses in the 40000+ range, such as 40001

« on: February 05, 2024, 01:24:07 PM »

in conjunction with the subtract you want to use a logical AND.

ModbusTCPCom1.Write("40001", Value AND (65535 - 2 ^ (b_Num - 1)))

I can't test that right now, but the 65535 assumes it is an unsigned 16 bit integer, it may need to be a 32767

That piece of code should only be in the MainForm or the Mainmenu form, which would be the only form being closed to exit the application.
