I have a 4-20ma input into my logo for a pressure sensor and then from my HMI i would like to change the parmeter in the logo from the HMI 

 Which parameter? It can not be that hard to write us what parameters it is.

I'm sorry, maybe I'm too stupid, but I do not understand what you mean.

What value do you want to change via the HMI?
The ON and / or OFF parameter of the analog threshold trigger?

Or do you mean something else?

 For this I asked in a post before. Why don't you answer to this?

In attachment is a video. This shows you the way how you can map parameters of blocks into the VM area.

In HMI you must use in the I/O fields in this case the words VW0 and VW2 as an integer with 3 decimal places.
