Post by mohammedben on Fail communication between CODESYS and Fuxa SCADA via OPC UA ^{CODESYS Forge talk (Post)}
hi, When I try to establish communication between CODESYS and Fuxa SCADA via OPC UA, the connection fails, and I receive the following error: 2026-02-15T08:38:13.618Z [ERR] 'codesys' connect failure! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.619Z [ERR] 'codesys' try to connect error! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.622Z [ERR] 'codesys' connect error! undefined (1) Note that there are no problems when I establish communication with the UaExpert and OPC UA Client Simulator software. I also previously tried communicating with RapidSCADA and received the following error: Endpoint with the specified security options not found. And when I try to connect with "none" in the security policy, I get this error: BadSecureChannelClosed I have tried almost all the solutions available online and have not found a solution. I hope you can provide me with a solution that solves this problem. Thanks in advance

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

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 timvh on FB string and naming ^{CODESYS Forge talk (Post)}
I see, you want to initialize the FB. To be able to initialise it like you described, you need to add the FB_Init method to your FB. (right click on the FB, select add object --> method). Then press the arrow down, to select the FB_Init (overwrite default implementation). In the VAR_INPUT section of this method, add the variable --> Tag : STRING; Then in the code section of this method add: THIS^.Tag := Tag; // copy initial value to local variable in FB Search Google if you want to know more about FB_Init. PS, reflection + instance path, is also an option if you want to get the full name of the instance (path) of the Function Block. See: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_instance_path.html

Post by imdatatas on Programmatically change Tappet on a cam ^{CODESYS Forge talk (Post)}
Yes, There is. As explained "Manual creation of CAM structure" on below section. Likewise tappet structure also can be create manual and value of the switching point can be change during IEC program running. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_cam_programmatic_creation.html Just create a cam table and define some tapped points as sample for your project. Then on project compile, the created cam tapped data is converted internally into a global variable list. By clicking "Display generated code" in the "cam editor", you can display the automatically created global variables for both cam & tappets. Regards, Imdat

Post by timvh on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
You need to activate an individual license (ticket number) for each device. THe hardware of each device is unique, so you cannot copy a soft container from one device to another. This license can be installed in a local (wibu - codemeter) soft container, or you could optionally activate it on a hardware (USB) key. The benefit of the key is that you can easily move it to another device, nor does it get lost when you replace parts of the hardware of the device or completely overwrite the image.
