Hello together I'm currently investing in possibilities to have a central engineering software / system for Codesys based controllers. Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Seit dem Update auf die Version V3.5 SP19 Patch 5 von der Version V3.5 SP17 haben wir das folgende Problem. Wir möchten von einem Gerät die Lizenz speichern. Damit wir nach einem neuen Raspberry Pi image die gleiche Lizenz für dieses Gerät brauchen können. Die Lizenz ist Geräte spezifisch so viel ich weiss. Bei unseren Geräten bei den Kunden hat es nicht immer eine Internetverbindung.

I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

At 19.1 the hFile_test should be RTS_IEC_HANDLE and always open-write - close in one cycle udi_handle: RTS_IEC_HANDLE; //handle-number. Is created by SysFileOpen udi_handle:=SysFileOpen(sFileName,Sysfile.AM_WRITE_PLUS, ADR(udi_ErrorCode)); udi_RetValWrite:=SysFileWrite(udi_handle, pRemBuffer, szRemBufSize, ADR(udi_ErrorCode)); //closing file IF udi_RetValWrite < szRemBufSize THEN ui_Error:=cWriteError; END_IF//error writing data udi_ErrorCode_Close:=SysFileClose(udi_handle);

Finally this solved my issue: https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/, and the official documentation https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager . Add the media folder to the PlaceholderFilePath. Like this: PlaceholderFilePath.2=/media/pi, $usb$ PlaceholderFilePath.2.View=1 PlaceholderFilePath.2.Volatile=1

Hello, is it possible to retrieve the hash of the current GIT commit hash from runtime? I would like to show it on hmi in a service section. Thank you
