Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi guys, I am new to the Visualization. I am having a problem. I have multiple web-panel to use webvisu. I have my software dowwloaded into the one PFC200. There are 3 screens connected to it. I noticed that if I switch page/visualisation on one of the screens, the others will change as well. Three screens are with different URLs that I set in the software. Is there any method to make them independently ? Kind regards, Jin.

Post by hsmw-wolf on How to fix Codesys Simulation Exception ? ^{CODESYS Forge talk (Post)}
Did anybody have a solution for this problem? I have the same issue and it occured as i wanted to continue work after the weekend. On Friday the simulation was working fine and on Monday thise error appears. There should be a more specific fault description to be honest. As I am writing I try to repair the installation and hope, that this will work. Still I am frustrated, because I don't know where to look for eliminating this fault. I am using CODESYS 3.5 SP19 Patch 5.

Good morning, The problem I encounter is very disturbing, when I try to connect to my project, it asks me to put in my username and password, which I do. However, I cannot connect and it restarts. the window to rewrite my identifiers. However it is the correct identifier and password I do not understand why. When I try to put false identifiers there strangely it tells me that these are not valid identifiers. There is something what can I do? Sincerely

Post by jinlee on Dynamic I/Os Mapping ^{CODESYS Forge talk (Post)}
Hi guys, Recently, I am working at the Dynamic I/Os mapping feature in Ecockpit or Codesys v3.5. I have been trying the libraries. However, it looks like it will not work as I wanted. I want to build the PLC which can detect all the I/Os itself and from there, I can do something on these channels. For example, the current setup is one digital input card, one digital output card and one analogue input card. Then, I want to add one more card into the setup e.g. one more digital input. Then, wago screen can detect this and we can assign them to tasks for example to control digital output. May I know is it possible ? Kind regards

Post by ofey on Modbus TCP communication ^{CODESYS Forge talk (Post)}
Hi! I tried setting up the PLC I'm working with (Beijer GN-9373) to connect to a modbus master running on a laptop. I have an ethernet connection (via USB-C to ethernet) between the laptop and the controller. I have tried following tutorial on how to set this up. I have added an ethernet device with the IP-address of the PLC. Further I added a ModbusTCP_Slave_Device with default settings. I get the error "Failed to open TCP Port: 1" when I try to go online with the PLC. Earlier I tested the exact same set up with the soft PLC from codesys. I can then read/write values correctly with the Modbus master i have running on the laptop. Hope anybody can help me with this, thanks in advance!

Post by hfelek on TargetVisu for Linux Package on runtime 4.12.0.0 install error due to Qt dependencies. ^{CODESYS Forge talk (Post)}
Hi, I am trying to make my runtime support TargetViso on 4.12.0.0 runtime. First when I tried to install package I got error due to missing libraries that are generated through qt-base. After compiling and installing related qt lib when I tried to install the package, I didnt get lib dependencies error but I got another error: [ERROR] The installed QT Version does not meet the minimum required version 6.4.2. Please install version 6.4.2 or higher and try again. When I check Qt version I get the following response QMake version 3.1 Using Qt version 6.5.0 in /usr/local/qt6/lib. I tried with Qt version 6.9.0 but that didn't help. Any idea on what coudl be the reason. When I looked for codesys related processes the related libraries were included within environment.

Post by tqvist on Gateway Start ^{CODESYS Forge talk (Post)}
Hello, I am trying to connect to my PLC (IFM CR711S) via VPN(EWON COSY). I have been told to use Gateway SP14 or higher. I installed CODESYS 3.5 SP20 Patch4. In the Codesys Installer Software I can sleect "Set Gateway Service" and I do so for CODESYS 3.5 SP20 Patch4. I can start the Gateyay and select About and it shows: "CoDeSys Gateway V3 - x64 Version 3.5.20.40" (see attached) For compatibility reasons I have to run my PLC code in 3.5 SP11 and when I start I can first connect but then somehow the system restarts an older version of the Gateway only displaying: "CoDeSys Gateway V3" (see attached) I guess my question is how to run an old Cocesys Software with a new Gateway?

Post by alsiddhartha on TextList name error (fake) ^{CODESYS Forge talk (Post)}
Hello, I’m developing a program and for some reason I got this error: C0193: Name '2,Recipe #2GVL' is no valid identifier I was creating a combo box and creating a TextList for my recipe. I couldn't find where the error was, until in the combo box properties in the 'Text List' property in the options it gives me to select, I found '2,Recipe #2' to be able to select (I never created a list with this name) and I can't find a way to delete that option or I can't find where that list is. I tried to delete the TextLists, delete the combo box, to clean the project, but the error still there. How can I delete this option (2,Recipe #2)? Or how can I fix this error?** Thank you.

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Dear Forum I have the following config: Codesys_IDE 3.5.20 Codesys_Virtual_Control 4.13 Codesys_License_Server 4.13 I know these are not the newest versions, but in my mind these should work. I have the same problem here. I have the license server installed on the host, and in the docker container(Codesys virtual control) I'm able to ping the license server. In the /conf/codesyscontrol/CODESYSControl_User.cfg I have added the following config: [CmpCodeMeter] EnableNetLicenses=1 LicenseServer.1="ip address of the host" I have tried it via the wbm web-page. I can create new license containers over there, but still no luck. I also have tried to run the docker container with the -s "server_IP" command. I have searched for some tutorial's but I couldn't find it. If anyone has some clue or can give me a push in the right direction it would be very very welcome!

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Thank you for your quick response, I have updated to the 4.17.0 (Virtual control and the license server). Now I am able to see the softcontainer from the Codesys IDE. But when I want to activate the license I get the following message: Licensing info not available. The device does not support this service (See picture). I then tried to active it via the WBM service like you suggested. But when I try this is get an error (see picture for error). I also tried to put RTS- in front of the serial number, but when I try this I get an error that the serial number is not correct. I think I'm getting closer, but I'm not there yet.

Post by mp9876 on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
Yes it had been the case I believe as I have seen that message regarding they were not the same. I had update the device though to match them and that still did not fix the problem. I gotta say I wanted to get out of that situation and attempted a lot of things and then I did two things at the same time that fixed my problem: Wiped the 64 bit version and installed the 32 bit version Installed latest SP20 I wish I knew which one of these actions fixed the problem but now I gotta catch up on this IDE learning; it's been quite a learning experience I have to say! Thank you very much for your time and advice; much appreciated!

Post by uluking on CodeSys2.3 Modbus 64-Bit Double Read Problem ^{CODESYS Forge talk (Post)}
Hi everyone, I would appreciate your help with a problem I've been working on for a few days but haven't been able to resolve. I am reading data from a Siemens PAC3220 energy analyzer using Modbus with Wago-8202. However, the device's energy indices are given as doubles. Since a double variable is 64-bit, it is not possible to read it directly. I have been struggling for days, I have written many conversion functions but I have not been able to get results. I would appreciate your help. I read 4 word variables and processed them. I am converting them according to IEEE-754, but I can't seem to read the correct data. I would appreciate your help.
