DDLV4 Message FB - NxIpDDL - Addional info to hmi message!

[PKlein]

Hallo,

is it possibile to add the information of the DDLV4 Message FB of the *Info.RecvFltString to the Addional Text of the error message?

This would help to find the problem faster.

Thanks for feedback!

Since 5.3 it is possible to display texts longer than 63 characters in Additional Text.

We check the implementation internally and provide a response.

Displaying a longer additional text works this way:

• The Unit/Addon FB has a string variable that is marked with UseInHmi
• When calling SetExtEvent, the additional text is set to the name of the string variable preceeded by @.

The DDL Event uses this feature already: The additional text is set to '@TraceText', which is a VAR_OUTPUT of type STRING(255) of the OpconDdlEventAddon FB. Before setting the event, the TraceText variable is filled with the trace text received from MES.

So much about how it works in general... 

Currently, the DDL event only uses the extended additional text in case there is a TraceErrorNo or TraceWarnNo received from MES. But we will check if it can also be used in this case.
