Post by marekxc on Little endian to Float from Modbus RTU ^{CODESYS Forge talk (Post)}
Maybe try going back to step one and: Var Reg1: WORD; Reg2: WORD; Reg12: DWORD; Value: REAL; end_var // program Reg1:= 4096; Reg2:= 14884; Reg12:= (reg2 * 65536) + reg1; Value:= DWORD_TO_REAL(Reg12);

Could not find the solution to this issue but I have side stepped this by creating a global variable MAX_SIZE.

okay but will this pass the array by copying it or it will be a reference to original array only.

I tried to change the name of the tap device to 'tap0,' but nothing changed. I don't think this is the problem.

Post by edepalos on Text list from sd card ^{CODESYS Forge talk (Post)}
Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes... Thank You in advance! Br, Ede

Post by smartcoco on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

Hello @eschwellinger, I installed the newer version of the installer, however the issue persisted. Do I need to do anything else other than updating the installer? Thanks for your help.

I had the same error. It took me a LONG way to figure it out, but in my case the problem was that I used LDATE_AND_TIME. It seems to be not supported, at least not in the Codesys version I used (3.5.16)

Try setting up your project environment. You can do this under Project -> Project Environment -> Press Button "Set all to newest". You have set your compiler, devices, etc in this project to the newest available versions.
