Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Im looking for a way to define predefined version of the same structures through "extends"/inheritance. What I want to do is best shown with an example: TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE (* this/below is not possible as I understand from the compiler?? *) TYPE LOG_DATA_BOOL extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.BOOL_; END_STRUCT END_TYPE TYPE LOG_DATA_INT extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.INT_; END_STRUCT END_TYPE etc. for LOG_DATA_REAL and ..STRING. The system will not allow me to "re-define" "val_type" however. Instead I must do the work-around of defining four different types with all fields individually defined. The benefit if I could extend the base item would be that Im (more) sure the structures are identical. In usage I can call in a specific type rather use the base type and assign which type. Usage by pointer/ref to log_data_base would also be easier.. (* Usage: *) log_data : log_data_int := (name, value etc.) (* Instead of: *) log_data : log_data_base := (name, value, val_type).. Is this possible to achieve in some way that I have missed?

@trusty-suire, The problem is not encoding. The problem is that codesys ands ' ' to the string. And the printer can't handle these character.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.

The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.
