Title: AdvancedHMIControls.CheckBox error Offset plus Number of Elements extends beyond
Post by: GraemeTownsend on April 08, 2018, 11:46:31 PM

Hi,

I am getting the following error on an AdvancedHMIControls.CheckBox

"General Error: Offset plus Number of Elements extends beyond the end of the requested tag."

The comms method is EthernetIPforCLXCom, and works fine for all else.

The PLC tag in question is a type of BOOL. (Set up in an array as BOOL[100]), PLC is a L27 Compact Logix

The Advanced HMI check box control has the same PLC tag set in both:
PLCAddressCheckChanged
PLCAddressChecked

It works fine, as expected, however the error flashes on and off continually. I can turn the error off using SuppressErrorDisplay = true. But I would still like to know what is happening?

I am using AdvancedHMI version: 3.99(t)

Thanks,
Graeme.

I would definitely start with testing it on version 3.99x because there have been a number of driver fixes since 3.99t

Hi Archie,

Upgraded to v3.99x, issue is still the same.

Happy to do any tests you may want.

Again, SuppressErrorDisplay gets me out of trouble.

Cheers,
Graeme

What element number of the BOOL array are you using? I will try to replicate today.

Hi Archie,

There is a BOOL array set up of [100].
I actually have 36 Check Boxes setup, consecutive, starting at Bit[40].

All display the same behaviour.

Thanks.
