Post by micik on Reverse bytes in an array ^{CODESYS Forge talk (Post)}
Hello, I'm getting the data in Codesys that is an array of 8 bytes. From this array, I need to foram LREAL number, however, because of different endiannes I need to reverse bytes in this array and then copy to a LREAL variable. For this I'm using a loop and it works OK. I wonder if there is a built in function to do this. I have found CAA Memory library but it has functions like reverse bytes in DWORD. But it seems it doesn't have what I need. https://content.helpme-codesys.com/en/libs/CAA%20Memory/Current/CAA_Memory/Reverse-Bit-Swap-ByteWord-order/ReverseBYTEsInDWORD.html What I need is a function to reverse bytes in an 8 byte array, or something similar.

Post by rjonker on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

Post by szotyi on Array of Program ^{CODESYS Forge talk (Post)}
Hi! What is the proper and the easiest way to call programs through looping of array of programs, or pointer of program? instead of calling the programs one by one: prog1(inputX: 11); prog2(inputY: 12); prog3(inputZ: 13); similar like: VAR programsToCall : ARRAY [1..3] OF PROGRAM; END_VAR programsToCall[1] := prog1(inputX: 11); programsToCall[2] := prog2(inputY: 12); programsToCall[3] := prog3(inputZ: 13); FOR i := 1 TO 3 DO programsToCall[i] (); END_FOR Thanks.

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods) ^{CODESYS Forge talk (Post)}
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?
