Post by alberto on ExportPLCopenXML is failing ^{CODESYS Forge talk (Post)}
I'm trying to export my whole project through the option ExportPLCopenXML. It seems working, but when I'm trying to import the xml I have the following error during the importation process: Object reference not set to an instance of an object. It seems a usual issue with this process that affects to the pointer to user classes inside a procedure. I receive this error for two general functions that have this pointer declarations in the VAR_INPUT section. It seems a bug into the export/import process of CodeSYS and I couldn't skip it so far. Anyone could help me? Thanks in advance.

Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Post by smartcoco on Dynamic object release issues ^{CODESYS Forge talk (Post)}
Dear, When I use "__NEW" to dynamically create the object "Object_1", and assign this object "Object_1" to another object "Object_2". At this point, I use "DELETE" to release the object from "Object_2". At this time, I cannot judge whether the object has been released normally through "Object_1" (in fact, the object has been released theoretically). Thanks for you help.
