Hello,

you can see the description in the following manual.
See the chapter 9.1.2.2.

Thank you Tweety.

Ok, more or lees, I understand like work visible in hmi, but when I go to wincc I see values that no mark with this option, for example take a i/o field, i go to properties -> process->tag, to the right of tag, i have two buttons, i click in the left button, and i see more values that isn´t mark with "visible in hmi", also I don´t undertand the next sentences:

"Accessible from HMI"-> Shows whether HMI can access this tag during runtime.


What´s mean "Shows whether HMI can access this tag during runtime."?.

bye.

Hello,

You create PLC tags in the tag table of your PLC program.
If you do not enable the option "Accessible from HMI", you can not see the tag from the HMI side.
You can not see the name of PLC tag in the column " PLC tag" in the tag table of your HMI.
See screenshot

Hello Tweety,

But in the case of s7300/400, I can see all until Plc tag in my wincc confort although I have clear "visible in hmi", then I don´t see the use.
