Post by rmaas on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Hi, The '' characters in Codesys are there only to indicate it is a STRING type. They are not actually added to the string, maybe you are adding them unintentionally in the concat function? You can send your data from Codesys to Hercules to verify... Another option is to send the data as an array of bytes instead of a string, with every byte representing 1 ASCII character. https://www.ascii-code.com/ This way you are 100% sure Codesys is not adding any unwanted characters.

I have a Array of constant size defined like this Var Constant MAX_SIZE :UINT := 10; End_var VAR array : ARRAY[0..MAX_SIZE] OF INT; END_VAR Now I want to pass this array to a function by reference, Function fun : INT VAR_IN_OUT CONSTANT MAX_SIZE : UINT; END_VAR VAR_INPUT array : REFERENCE TO ARRAY[0..MAX_SIZE] OF INT; END_VAR but when I run this it gives strange Errors Error : Cannot Convert type 'ARRAY [0..MAX_SIZE] OF INT' to type 'ARRAY[0..MAX_SIZE] OF INT'
