Post by johnbomb on Ignore Dependencies When Loading Package? ^{CODESYS Forge talk (Post)}
I'm trying to load a .package into Codesys 3.5.21, but the package is intended to only work with Codesys 3.5.18.0 and is configured with dependencies on the specific versions of other packages included with 3.5.18.0, and 21 has newer versions so the package will not install. I would like to install the package anyway to try and get things working on a newer Codesys version, since for some reason the installer for .18 errors out and doesn't fully work in my environment, but .21 seems to work fine.

Post by jampid on Reset an Array[] in one line, possible? ^{CODESYS Forge talk (Post)}
Bonjour, La librairy est SYSMEM en Codesys v3.5. Pour accéder à la fonction : SysMem.SysMemSet. Il y a plein d'autres fonctions intéressantes : SysMemSwap, SysMemMove, SysmemCpy, ... Cela évite de créer des Boucles et permet de bien utiliser ADR() et SIZEOF() Il existe aussi une librairie CAA Memory qui mérite intérêt; Par exemple MEM.MemFill pour remplir un tableau d'octets. Bons développments! Il suffit d'ajouter ces bibliothèques dans le gestionnaire de bibliothèque pour les utiliser. JM

Hello all, could you tell me whether I need an additional license in order for v3x64 to execute the DLL? Is there some manual on how to proceed? Other than the rather generic message loading Component failed Lib_XMATH.dll I have no further hints. Many thanks for your feed back. PS: I tried a similar experiment (i.e. generating a native dll for windows and having it executed by the Python VM this worked without an issue).

Post by patliby on Cannot Find "Automatically Generate POUs" Option ^{CODESYS Forge talk (Post)}
I would like to enable the feature to automatically generate POUs for Project/Library properties in some of my library/project files. The Codesys help pages indicate it should be on the bottom of the Project Information Summary tab, but mine has no such options (see screenshot). Is there somewhere I have to enable this overall feature or any other prerequisite I am missing? I am using Codesys 3.5.19.20 Reference https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_project_information.html#UUID-9ddc3572-a024-5a49-c0c1-31677991a419_id_c95bfe46c6c18a67c0a8640e01715107_id_0a188ec6fa561b9fc0a8640e0019d8bf

Post by vsgn on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
Hi, in my experience, the best options for such a case could be: 1. Pass a FunctionBlock via VAR_IN_OUT, containing all variables, mehods and properties needed for the logic of this graphic element (be aware of implementing correcly both get and set accessor for properties) 2. Pass an Interface via VAR_INPUT, of which you can use obviously only Properties and Methods. This is much more elegant for me. Here, you can just pass directly the instance of a FunctionBlock implementing such Interface as input. Hope you'll find this suggestions useful.

Post by gabrielarffa on Modbus TCP/IP having problems with global variables ^{CODESYS Forge talk (Post)}
I'm using Modbus TCP/IP to communicate Codesys with Elipse E3 as the master for a college project. I have made a list of global variables to organize the programming in two different POUs. The problem is, when I try to do the mapping of variables, the program informs me of an error due to the identifiers having a "." on their names. Do I have to reorganize my code to make it an unified block or is there a way to declare their names without changing all the code structure?

Hi everyone, I’m using an IFM ecomatBasic CR413S controller and having trouble connecting it to CODESYS 3.5. I have CODESYS SP18 installed, as recommended in the manual, and I’ve tried different patches. I’ve also installed all the packages provided on the IFM website for this controller. I can successfully connect to the ecomatBasic template, but I’m unable to connect when using the CR413S-specific template that includes all the inputs and outputs. Has anyone encountered this issue or knows a solution? Best regards, Jan

Post by berkdan on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hey tk96 Thank you for your help. I have found the reason why fbreader stuck. It was not the program but it was the gcode itself. G21 command blocks the reader. And multiple G codes in a line also blocks the reader. My code was: N010 G21 G17 G90 -> Blocked the reader When i change it to: N010 G90 N020 G17 Then it worked. The only thing i did not get is why the reader did not thwor error. ErrorId was SMC_NO_ERROR. Anyway, it is now working. Thanks again.

I'm trying to use an fbMsSQL_compact function to read data from an SQL database. It works with some databases, but there is one database that I can't seem to get it to work on. It's set up the same as the other databases that I've tested with the only difference I see is that the name of the database is cut off in the status message. I'll get a message like "User: User logged out succesfully from database: 12345" But the whole name of the database is something like 1234567.
