HMI and PLC Memory addresses are not the same.

4 posts in this topic

Hi!

We have a GOT2000 HMI with a Q06UDVCPU system. During an investigation, I found that the address on the HMI (for example D10120) and the address in the PLC (D10020) are different.

The value is the same, it appeared instantly during monitoring, but when I searched for it, didn't find it (I couldn't find the D10120 in GxWorks2, and couldn't find D10020 in GtDesigner3). The HMI's address is 100 higher. I never saw anything like that.

Where is this difference can be set?

Knowing this, I can navigate in the program..it's just annoying.

This is impossible.. Why do you think D10120 and D10020 are the same ?

Most likely one is being written into the other. Maybe via an indexed register

Index registers were my first thought too.

instead of using FIND for the D10020 address, which will only show contacts or coils directly addressed as such. 

 use cross reference. That will show any place that address is used in Bulk moves

See examples from my program.
