Accessing bit level in a DINT tag

[andreaboschetti71]

I have some squareilluminated buttons with toggle output status that change a bit in a DINT tag (i.e. ZZ_TEST)
So I set PLCaddressClick and PLCaddressValue to ZZ_TEST.0. Clikking button works fine as I see changing the bit but the button status doesn't change (always dark color)

Same problem with graphic indicator. nothing change changing bit associated to it

My tests only checked the writing of bits, not the reading, so this one slipped through. Try this patch.

- Download and unzip the attached file
- Replace the file in AdvancedHMIDrivers\Support
- Rebuild Solution

Hi ,
I've finally got an Iso of SP1 for 2010 studio andinstalled it . Transfered a testing project from 3.97e to 3.98f .
It has a screen for manual operation of solenoid valves using the square button . The target PLC is an AB L32E using the Enet driver . The buttons write to the PLC fine but the read does not work . I added a basic label to check the dint was being sent by the PLC - the value is correct . I did try the patch but it didn,t work with 3.98f . Is there anything else I should try ?

Change of subject - I have just acquired a cheap ( for the UK ) £110 Windows 8.1 tablet called the LINX and
AHMI is running fine - it is very handy for machine testing .

I just did a quick test with a CompactLogix (L35E). I added a BasicLabel with PLCAddressValue set to DINTTag (a controller scope tag). I added 3 BasicInidcators and set PLCAddressSelectColor2 to DINTTag.0, DINTTag.1, and DINTTag.2

I then added 3 BasicButtons and set PLCAddressClick to DINTTag.0, DINTTag.1, DINTTag.2

When I run the application, I click the first button, the BasicLabel got to 1 and the first BasicIndicator lights up.
I click the second button, the BasicLabel goes to 2 and the second BasicIndicator lights up,
I click the third button, the BasicLabel goes to 3 and the third BasicIndicator lights up.

This is all as expected. Am I not testing similar to what you are?

Sorry Archie ,
I popped into work and found I forgot to mention that the DINT was part of an array . ie
Display[10] for bits to PLC and Display [13] for bits from PLC . These were working with 3.97e .

This will be fixed in the next release of 3.98g or later
