HMI tag of type DB_ANY

Hello,

I have PLC Tags, that are a structure that contains inside a datatype DB_ANY.

Normally when I want to create a group of HMI tags, I usually open HMI Tag Table, under PLC Tag choose corresponding DB and double click to the structure. Then I choose to synchronize so WinCC can use PLC tag names.

However inside the struct I have a datatype DB_ANY  which is invalid type for HMI. HMI Data type can accept Uint for example.

How to solve this problem?

Hi!

I don't know if a DB can be accessed with an area pointer from the HMI... but, I have found some information on the area pointers available in an HMI. A link to a FAQ to synchronize the date and time using an area pointer, and a second link to a manual explaining how to use "Job Mailbox" has been attached.

Finally, a link to the manual has been attached:

Hi,

the real problem is that as PLC Tags everything is OK. and this is described in the manual (extract is given in the attachment). These data types are described in S7-1500 Motion Control in TIA portal manual.

This thing is that when I as a user create HMI tgas from this structure and then use option to synchronize it with PLC Tags, next HMi compilation fails since this is invalid types for HMI. 

In any case the rage of possible values are between 0 and 65535 (16 bits = 2 bytes = Unsigned Integer), so Uint seems like a good equivalent, but still compile process is stopped because of this.

Actually, the problem exists if HMI application is WinCC Professional.

I have made a simple test project. It can be downloaded here:

Actual compile error message is given in the attached pic. The compile runs successfully, if SIMATIC PC station is replaced with for example HMI comfort panel.
