Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Post by sigurdrb on OPC server in "Communication manager" ^{CODESYS Forge talk (Post)}
Hi! I was thinking of switching the OPC server config from "Symbol Configuration" to the "Communication manager" in the device tree. I Have a lot of arrays of structs that I have previously declared in the "Persistent Variable" object in the device tree. It seems as it is not supported to directly expose persistant variables to the OPC server like the "older" way of doing it in the symbol config. Is this correct? Do you recommend to just do it the old fashioned way, or should I edit the structure of the global variable list / persistant data / OPC server and set up the OPC server from the "Communication manager" object?

I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Post by turndapage on Can't Add Symbol Configuration ^{CODESYS Forge talk (Post)}
I've got a Weintek HMI with CodeSYS built-in. I've got it connecting to CodeSYS and downloaded. The connection guide says I need to add a symbol configuration by right-clicking on the application and adding it, but it does not show up in the available objects. Is there something else I have to do to create a symbol configuration object?

I have created an EtherCAT slave code and fixed two slaves (IDs written in the 0xF050 object dictionary). The module IDs are 0x1 and 0x101, respectively. It can be scanned normally in TwinCAT, but when scanning in CODESYS, it reports an error. Why is this happening？text in the second pic means 'device cannot be found in repository'

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by alexgooi on How to protect library project? ^{CODESYS Forge talk (Post)}
Hi aniket-b, If you save the library as a compiled library you are not able to see the source code. When the end user tries to view inside the object, CODESYS will give a notification that the source code is missing, see attachment. In short if you don't send the source code, it will not show.

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello, Without much info, I would assume that this is an optional object on the EtherCAT network and it's either disconnected or the address doesn't match. I would look into the devices manual or contact the manufacturer for further assistance. And, I would have posted a new topic instead of using a non related one... Cheers!

We used this with shared memory codesys. and work. OpENer is an EtherNet/IP™ stack for I/O adapter devices; supports multiple I/O and explicit connections. And we adapt this also for Implicit message. But for arrive to the end we spend a lot of time. :-(((

Now that SP21 is out, what's the answer? I want to get a pointer to the TxPDO and RxPDO structs. I can generate a STRUCT declaration from the ESI file with a bit of Python. I just need to get the pointer from the ETC_Slave.

Post by mubeta on parker servo and position ^{CODESYS Forge talk (Post)}
Reading between the lines of what you did not specify, it therefore seems to appear that in the programme, at the end of the movement order, there is an order to remove power and switch off the pulse modulation. if this is the case, it is obvious that the motor then remains free. If the position is to be maintained at the end of the movement, the motor current modulator, which on the PLC side is controlled via the MC_Power method, must not be interrupted. Another possibility is that in the motor drive settings, the standstill torque current is set very low or zero and without position monitoring. You have to check this via the servo motor drive.

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
Sounds feasible, but how would I create this object so that both applications would use the same instance of it. If this did work, it's still not really the solution I am looking for as it would mean mapping every variable I want to use on the hmi through this object vs I was hopping all the GVL variables would be available.

Post by eschwellinger on Licensing info not available. ^{CODESYS Forge talk (Post)}
yes and no ... if you run the license server on the host (to serve licenses to the docker instances / vplcs then there is no runtime which could check the licenses on the host. Therefore you need the CODESYS WBM to activate or check the licenes or you could use in CODESYS IDE the licensemanager ( not the one for the device licenses) but you have the the IP of the license server that he know where to search for the licenses ..tool options i guess to add it, will add a screenshot later.

You need to create a function around this function to check the dialogs you use in your program. That's the way i have done it.

Are you using Bookworm and which Rasperry PI? Check the logfile with ssh connection tail -f /var/opt/codesys/codesyscontrol.log It should work with 4.11.0.0 release. Just use the ABL licenses - (check the license metrix of your application)

Are you using the Wago Runtime - please check the version information on scan. Either 6.x.x.x or CODESYS 4.x x.x SL Runtime- and always check the plclogger in such cases.
