The server doesn’t allow anonymous users. You need to configure a username/password for the connection.

Post by cihangur on Application has invalid license metrics. ^{CODESYS Forge talk (Post)}
Hi, I have a "CODESYS Control Standard L" license and I use Ethercat and Profinet in my project. The project works seamlessly with two fieldbuses. However, when I add modbus_Com (Serial) or 1 OPC Tag to the project, the program throws an exception (Application app=Application has invalid license metrics!). My license should support 10*Modbus and 512 OPC Tags. Why might this problem occur?

Post by bryandimino on OPC Da Server Code Meter Issues after Enabling License ^{CODESYS Forge talk (Post)}
I'm trying to get the OPC server setup on my machine and currently I'm not having luck. I went ahead and got my license setup. However when I go to run WinCoDeSysOPC.exe I get an error message that I don't have the code meter licenses installed. Does anyone have any ideas on how I can fix this issue?

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Hello. I forgot the password to ControlWinV3X64. I watched on youtube that i must delete folder from "ProgramData/CODESYS/CODESYSControlWinV3x64" But the problem is that in the the CODESYS there is no folder named CODESYSControlWinV3X64. I checked if the folder is hidden but it's just not there. I can't find it and can't reset the password. Could you help me to reset this password. I even tried to uninstall and install the CODESYS but nothing helps.

Post by pedrorgd on SFC Exit Action during SFCReset Flag ^{CODESYS Forge talk (Post)}
I have an SFC POU with an SFCReset Flag that I use to restart it from the beginning. It works properly. During an Action Step I set one variable to TRUE and I reset it to FALSE during the Exit Action. My question is if this Exit Action will be activated -and the variable reset to FALSE- if I get out of the active step using the SFCReset Flag.

Post by timvh on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
You should only open de COM port once and then leave it open. This hCom should not keep on incrementing. (off course when you are done communicating, you need to close the COM port)

Hi TimH Thanks for the information, I thought that was the case so have stepped through the code and found an error that wasn't closing the port, therefore hCom was increasing. Thanks

Solved. Just in case that someone else is now to this also. It seems that the xDone of the TCP_Connection FB goes true once client disconnects and then you need to reset the FB by setting the xEnable to false.

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne
