Hi,

I  downloaded  document & Program file from the below link of application example.

https://support.industry.siemens.com/cs/ww/en/view/67261457

In the HMI Tag I found an address that is  "DB [DBNr] DBX [offset_byte1].0" but i can't understand which DB & Byte is defined of PLC program by this HMI Tag.

Please explain the meaning of this HMI Tag.

Find the attached file for your better understand.

------------------------------------------------------------------------------------------
Split from PLC DB to WinCC HMI Tags.

Hi Mustafez,

DB11. DBW8 (Int) == DBNrv

DBNr == DB [ DBNrv ] . DBW 12 (Int)  -->DB [ DBNr ] . DBX [ xxx ]

The value DB11.DBW8  --> ParameterAnzeigen.Axis_HMI //Initial value 1.

In the second and the third network  (FB 1) you have seen for what the program used variable. Depend of  value comparing we will read/lesen or write/schrieben data (HMI).

Best regards

Hi Murof,

for the first than you very much for all post. A great deal of knowledge about HMI i adopt for you.In this case it 's not the multiplexing. In this case we have some version "indirect addressing" via PLC,

FAQ  How does adress-Multiplexing work:

in some example:

Dear zzVss,

Thanks for your explain. but I can't understand the explain. my confusion  the address data type is Bool but they use DB as int for defining the Bool Data type. Can you little more explain this HMI tag in details  and which bit is set by this tag on the program?

if possible give an example about this type of Tag.

Dear Murof

In this 2 FAQ is everything explained you have to know.

I do not understand the last post of User zzVss?????

Please zzVss read first the FAQs an then write again

 Hi Murof,

the 1st  image show (when opened) program that the HMI tag don't use multiplexing.

the 2nd image show when HMI tag used in multiplexing (this the picture we will see in FAQ 

How does tag multiplexing work image3).

I try have explained very simple haw in this case (this project) used fix HMI tag by different value.

In the project you have seen haw this working (see image):

For better understand tag  e.g. (in the project)

ActPackAxis [bool]     =>   DB [DBNr]. DBX[offset_byte7].7

DBNr depending of logic operation (PLC) will be 72 (Int)-> DB72 or 172 (Int)->DB172.

offset_byte7 (Internal tag--Int ) depending of  operation in panel  (Cross_Reference for offset_byte7)

Best regards
