Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

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 fraccaroli on New Codesys Library Dependencies ^{CODESYS Forge talk (Post)}
Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Hello, what CAA stands for? Since it is a collection of different libraries, does it mean it is created by some specific organization? Thanks!

The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Thank you wollview, it is clear now, it is due to security reasons that access to the file system is restricted.

IDK why you lost values but about the limit, when you compile, you should have the information about the memory remaining.

Post by as1984 on Codesys Control log "eventbuffer full" ^{CODESYS Forge talk (Post)}
Have you found a solution for this? Id be thankful for every hint. I have a controller with the same events in log and sometimes it crashes. Memory of the codesys3 task rises until the linux system kills the task because the controller runs out of memory.
