How to start DataLayer Method by PLC

[stan46]

Hi,

is there a way to start a Method in the DataLayer i.e. diagnosis/confirm/all-errors by PLC?

Thank you

To execute a datalayer methode like (confirm errors) just write the node without a value. See example below:

VAR fbExecCmd: DL_WriteNode; 
strNode: STRING(255):='diagnosis/confirm/all-errors'; 
END_VAR 

fbExecCmd(Execute:=True, NodeName:=strNode); // ToDo check for Done or Error
