Post by scarter on Import/Export PLCOpen xml Task Configuration ^{CODESYS Forge talk (Post)}
I'm Having the same issue. If I highlight PLC Logic and import it erases everything else and replaces the Task config. If I highlight the Application I get the same result. Simple manual fix is click and drag the task config onto the origional Application, and delete the second one. Easy fix but not the expected result of importing task config.

Post by kees-b on PLCnext Phoenix Contact ^{CODESYS Forge talk (Post)}
Hello We started with the new design of Codesys, through a "CODESYS Control Standard S" license. However, after installing the license, connecting, etc. (without any problems), we cannot get the program into the PLC with entries that we have not seen before. Is there anyone who has also experienced this? Better yet, does anyone have the solution?

Hi @eschwellinger yes I have been using xDoubleStorage It happened again and I checked and the files were still there with there contents, restarting codesys or rebooting would not even reload them. Doing a download and then starting the PLC loaded them and began working again. Some sort of mismatch error or something?

Post by solidlogicguy on Little endian to Float from Modbus RTU ^{CODESYS Forge talk (Post)}
Hello, I got a device from which I require to read values from I am using a WAGO PLC 750-8212 and I am communicating through Modbus Master FUNCTION BLOCK from library WagoAppPLCModbus in Codesys 3.5 to this device. I already receive data from the device that is a CVM to monitor voltage from a fuel cell. The technical support of the company that makes these devices says that the data is sent in little endian form. And I want to convert it to a float value. The tech support sent me the next instructions of how to do it but I am new using codesys, so any advice or help I will really appreciate so much. Message from tech support: The process is complicated, better to do it with already implemented library in the language/program you use. Basically the process should be next: To convert the two Modbus registers containing parts of a 32-bit float in little-endian byte order to a floating-point number using mathematical operations, you first need to combine the two 16-bit integers (assuming reg1 is the lower word and reg2 is the higher word) and then interpret the result according to the IEEE 754 standard. Given: - Register 192 (reg1) = 4096 - Register 193 (reg2) = 14884 Step 1: Combine the two registers. Since we are dealing with little-endian byte order, reg2 is the high word, and reg1 is the low word: combined = reg2 * 2^16 + reg1 combined = 14884 * 65536 + 4096 combined = 975175680 + 4096 combined = 975179776 Step 2: Convert the combined value to binary: combined_binary = '1110101101011100000000000000000' Step 3: Split the binary into IEEE 754 components: Sign bit (1 bit): 0 Exponent (8 bits): 11101011 Mantissa (23 bits): 01011100000000000000000 Step 4: Convert the binary exponent to decimal and subtract the bias (127 for 32-bit floats): exponent = int('11101011', 2) - 127 exponent = 235 - 127 exponent = 108 Step 5: Calculate the mantissa as a fraction: The mantissa in IEEE 754 format is the fractional part after the leading 1 (which is implicit). Therefore, we need to convert the binary mantissa to decimal and add the implicit leading 1: mantissa_fractional = 1 + int('01011100000000000000000', 2) / 2^23 mantissa_fractional = 1 + 18688 / 8388608 mantissa_fractional = 1 + 0.002227783203125 mantissa_fractional ≈ 1.002227783203125 Step 6: Combine the sign, exponent, and mantissa to get the float value: float_value = (-1)^0 * mantissa_fractional * 2^exponent float_value = 1 * 1.002227783203125 * 2^108 Because the exponent is quite large, the resulting float value is a very large number.

Post by tyronnosaurus on ReceiveWatchdog FB not working on J1939 P2P PGNs ^{CODESYS Forge talk (Post)}
Hi guys. I've got a device that sends a status message over J1939 and a PLC running Codesys to receive it. This message uses a P2P PGN (as opposed to a broadcast PGN). Codesys can only read it if I mark the J1939_ECU as "Local" (see screenshot 1). The message is received correctly, that is not the problem. The problem is detecting if the message stops being received. Local ECUs have no Watchdog checkbox to detect if the message has been received in the last X seconds. In order to implement a watchdog, I've used a ReceiveWatchdog FB. The same code works well for any non-P2P message, but doesn't work for this particular P2P message I'm trying to monitor. Even if I physically disconnect the device, ReceiveWatchdog.xBusy stays True, and ReceiveWatchdog.xError never triggers due to a timeout error. Is there any caveat in the ReceiveWatchdog FB that makes it unable to monitor P2P PGNs in Local J1939_ECUs?

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, according to Codesys, the problem should be solved with version 4.3.0.0. After the update to version 4.3.0.0 I had the problem that the recipes weren’t saved correctly, but loading was okay. Return to the version 4.2.0.0 didn’t change the behavior. Strange… So I uninstalled the update, cleaned the project and built it new. The known behavior of version 4.2.0.0 was back. Update to version 4.3.0.0, clean and build it new, it works. Even with version 4.2.0.0. Strange, but okay. Notice: ManCommands.LoadRecipe() no longer writes into the PLC. Just as it should be. As of now, I can use the new version.

Post by nmcc on Viewing PDF in WebBrowser Visual Element ^{CODESYS Forge talk (Post)}
I am trying to show a PDF in a WebBrowser element. I have the file saved to the drive of the HMI/PLC. I am linking it in the URL parameter of the WebBrowser using the following directory link. 'http://localhost:8080/$$sdcard$$/FileName.pdf'. This allows for the program to download without any errors. When I navigate to that screen it is just a white box and nothing shows. I attempted putting the same link in the show parameter and I get a loading icon on my cursor when monitoring the HMI with my PC. Any help is appreciated. Thank you.

Few of the variables used as a Pushbutton form the Visualization. These 'BOOL' Variable getting unlatched automatically even though there is no write function in the Overall project. All of them are 'Read' functions, at the same time few other BOOL variable behaviors are seems to be fine. I have tried, clean all and download, serval time restarted the hardware.

Despite working on it for days, I haven't achieved any results. I followed the necessary steps one by one as mentioned in the file you sent, but there hasn't been the slightest change. I couldn't find the step you mentioned "Set the 'Can Board Type' to PCAN USB" in the Word document. There is no such setting anywhere I looked. Is there a more detailed explanation available, or can you explain it in more detail? What am I missing?

Post by jari-koivuluoma on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge talk (Post)}
I have a need to send messages between 2 PLCs and I cant use network variables (because of size limit) so I tried writing this simple test program. This seems to work fine. I can send messages back and forth when a first "Start server" and then "Connect client". See the attached image. However, if I disconnect the client by setting ClientConnect to false and try to re-connect then the TCP_Client just gives me TIMEOUT error. When I stop and start the server again, then Im able to reconnect. How is this supposed to work? Why reconnecting wont work. There is not other way of disconnecting the client than setting xEnable of the TCP_Client to false. This is just a testing program and I will try it on 2 seperate devices once this works.

Hi, We are working to provide our customers with CODESYS operation on our hardware product ( https://elprotech.com/product/el-qe-e-quantum-edge-series/ ). I'm trying to enable a CODESYS license (Soft container) on our product running ARM64 linux. This problem am having looks similar to here: https://forge.codesys.com/forge/talk/Runtime/thread/6d29b6b4de/ and here: https://forge.codesys.com/forge/talk/Runtime/thread/a2d0c63375/; but I am not running docker, and I am not re-installing a license.

Thanks for your reply @eschwellinger. Update : the is problem is resolved. It was done by renaming the User database file (/var/opt/codesys/.UserDatabase.csv) as deleting it was risky. After restart the IDE asked me to create new user. On doing that the problem got resolved. Reference for members facing similar problem/s : sudo systemctl stop codesyscontrol sudo mv /var/opt/codesys/.UserDatabase.csv_ /var/opt/codesys/.UserDatabase.csv_.old sudo systemctl start codesyscontrol
