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.

When you have a deep object structure where not all values are not exposed to OPC UA, the top object will not have a V check mark but be filled fully out. In that case CODESYS do not always registrate changes to inner object. Solution set a V in the checkbox of the top object, build, download. Now you can browse, but all values in the top object will be selected, then you can deselect the ones you don't want, build, download and it works

Post by timvh on FB string and naming CODESYS Forge talk (Post)
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';
