Variable type not suitable for archiving

[fandersen]

Hello,

in my log viwer I get a servere message that the variable type is not suitable for archiving. How can I diagnose the problem properly?
I know how to spot the affacted data points but not the element. Is there a way to get the elementName by elementId?

Code: Select all

Unexpected state, Variable type not suitable for archiving (ErrNum=14),

[D:\\workspaces\\3.12\\workspace\\Exe\\DataNew\\ValueArchive\\Archive.cpp:2648]

Hopefully someone can help me with this. :side:

You can get the dpe name by id in CTRL with the function 'dpGetName()' or with the tool 'WCCOAtoolNameToId' (in online help under Reference tables -> DP identification).

Hello,

in most of the cases you can get rid of this error with the following list of actions:
-- open a para-module
-- select the dp-element for the given DPE-ID
-- open the configuration panel for the _archive-config
-- select another archive
-- save the configuration
-- make a fileswitch for the archive which has written the log-message
-- open again the configuration panel for the _archive-config
-- select the archive which was used before
-- save the configuration

A loss of data will not occur when doing these changes.

Hello Leopold,

thanks for the solution, that solved the problem.

I created a CTRL-Script which helped me finding out the affected dpElements.

Code: Select all

int dpId = 435;
dyn_int dpElements;
    
dynAppend(dpElements, 45);
dynAppend(dpElements, 46);
dynAppend(dpElements, 47);
dynAppend(dpElements, 48);
    
string elementName;
int i;
    
for (i=1; i
