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'

Post by comingback4u on Memory Address Overlap ^{CODESYS Forge talk (Post)}
Hello, We use a controller that comes with a bunch of predefined faults. These faults are considered active and historic. They are a 32 byte array but only take up 26 bytes of data. Because of this the historic faults start at address 26 instead of 31. Active faults variable take up address location 0 to 31. Historic faults variable take up address location 26 to 57. Because of this overlap I get an error that these overlap and it wont allow me to download to my controller. This isn't an issue in 3.5.5.4 but becomes an issue in newer version. Is there a way to turn this off? If I change the address location, the historic faults then become broken without doing some manipulation in the code. The software will build just fine. Thank you for your time.

Post by imdatatas on Problem of assigning physical addresses to variables of type ARRAY OF ARRAY as MW and QW ^{CODESYS Forge talk (Post)}
Hello, I am encountering an interesting problem as below in SP20patch5 variable definition area. I think this is a bug. As can be seen in the attached screenshot, it assigns the same %MW or %QW address to all elements of the array. I hope Codesys team can solve this problem in the next version. Best regards, Imdat
