Communicating with AB MicroLogix1000

[Jaguar]

Hi Archie, as I double click the MainForm.vb. It opens up in vb codes, not in form. When I click the Start, the form  opens. But it is form only without any component.

Regarding, how I added panel meter etc. It was an old project, I developed it may be two years ago. I think when I initially developed the project, I added component to the MainForm from component box. Now as I open the old project, and click the MainForm.vb, it opens now only in vb codes. Otherwise, that old project works fine, without any change. I mean through HMI no issue, no issue in entering the cycle number etc.

Now I want to use the same project modifying little bit on the form side. That's all I intend to do.

[Archie]

Can you right click MainForm.vb in Solution Explorer and select View Designer?

[Jaguar]

Hi Archie, I did that and the MainForm is now opened in Design value.  How do I access DF1 driver property from there? I right clicked Digital Panel meter and could see its property

[Archie]

On the design view of the MainForm there will be a component tray at the bottom. Click once on the driver, then go to Properties Window

[Jaguar]

Good Morning Archie! Thanks once again!

Here I attached the screenshot(property) for the driver from component tray of the form in design view. Do you see anything not right on the property?

[Archie]

Change EnableLogging to True, then run the application to get the error. Then look in the debug directory and post the log file that was generated

[Jaguar]

Hi Archie,

Here it is, I think you are looking for,

Exception thrown: 'MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException' in MfgControl.AdvancedHMI.Drivers.dll
Exception thrown: 'MfgControl.AdvancedHMI.Drivers.Common.PLCDriverException' in MfgControl.AdvancedHMI.Drivers.dll

[Archie]

There will be a log file in the \debug directory

[Jaguar]

You meant this Archie? Sorry if I am not getting it right:

[Archie]

Yes, but I do not see any write command. All of them are A2 which means it did not attempt to write anything. The write is an AA value.

[Godra]

Jaguar, can you zip up your whole solution and share it on the dropbox?

[Jaguar]

Hi Archie, here are log. I attempted to write and got "Failed to write value. No response from PLC during write." message. But don't see any A4 value.

@Godra, you meant Google Share drive?

[Godra]

Google Share Drive should work as well.

[Jaguar]

Hi @Archie & @Godra, just to let you know, I built a new HMI project, which is working fine no issue. Discarded the old one (could not figure out what was the exact issue).

Anyway, thank you VERY MUCH to both of you! I know how busy you both are, but still took time to respond to my post, even on weekend!

Thanks one again!!
