AES acknowledgement Status Representation

[AMRPatricio]

Hi all,
is it possible to change the acknowledgement status representation( "x", "xxx") for something else?

My customer really do not like those symbols.

Thanks in advance,

Antonio Patricio

There is no standard functionality or option available to change the representation of the acknowledge status.
You could modify the aes.ctl library and
-- read the column information
-- replace the content
-- write the column information
everytime when the AEScreen table is updated executing the work function aes_workCB().

I would prefer a solution that does not require to change the 'aes.ctl' library, because it so big and has regularly code changes.

So without changing aes.ctl the options are:
1) Replace the 'Ack' column without your own ack column
2) Modify the function 'aes_editAlertsBeforeDisplay' in the library 'asModifyDisplay.ctl', so it (only) replaces 'x' and 'xxx' with your values

The functionality mentioned in option 2) only works under specific prerequisites and is implemented for a very specific function.
Therefore using another approach should be the preferred solution.

As far as I know the information shown in the "ack" column is a combination of different _alert_hdl attributes.
If you want to implement your own "ack" column you have to define an own C++ function which implements business logic.
How to implement a user defined function which can be used in the AEScreen is described in the WinCC OA Documentation --> System Management --> Diagnostics --> Alert and Event Panel --> Example of how to add a user-defined column.
