Problem modifying DPTs used as REF

[nmnogueira]

Hi,

I am having two different problems trying to update DPTs used as reference in another DPTs. What I am trying to do is to add a new element of type bool to the DPT.
Notice that these two problems appear in different DPTs. Each DPT always shows the same behaviour.

Problem 1
When I try to change, I get the following error:

Code: Select all

WCCILdata    (0), 2017.09.19 10:41:43.266, IMPL, SEVERE,     54, Unexpected state, PersDpIdentification, handleManipTypeChangeMsg, changeType unmoeglich, type container returned 2
WCCILdata    (0), 2017.09.19 10:41:43.266, SYS,  INFO,      119, Last error repeated 940 times.
WCCILdata    (0), 2017.09.19 10:41:43.266, PARAM,SEVERE,     54, Unexpected state, DataManager, handleManipDpTypeChangeMsg, Type change failed

Problem 2
When I try to change, the change is done correctly but the changes are not propagated to the DPTs which use this DPTs as a reference.


Any ideas?

Maybe changing the datapoint type is not possible due to an inconsistency in the database.
How are you changing the datapoint type (PARA module, ASCII manager, ...)?

Do you already have historical data for the datapoints which belong to the type which need to be changed?
Would it be possible to loose the historical data?

I'm changing in PARA.

I do have historical data but it's not an issue to loose that data.

Just for information to all users in the forum.
The issue was analyzed by the support team. I could not find an easy solution to extend or modify the dp types where the problem occured as the dp type was used in many other dp types as type reference.
As loosing historical data was not a problem in that project a complete new database was created.

In other cases maybe another solution can be used, e.g. deleting only the corrupted dp type and recreating again.
This is only possible if it is not used as type reference. Otherwise you have to change all type references and delete the reference information to the corrupted dp type.
