Post by peterkcontrols on TargetVisu started in windowed or not full screen ^{CODESYS Forge talk (Post)}
Hello, I am using Codesys on an industrial pc with a single monitor. I would also like to have a separate vision software running on the PC and would like to display it half screen. When I run the soft PLC the my visualization screen appears full screen, I would like to be able to set the size of the visualization screen so I can display other software on the monitor. Is it possible to set the width/height of the targetVisu? Anyone try something similar? I would like to avoid having to put it on a Virtual Machine. Thank you

Post by pernockham on Images not shown in webvisu ^{CODESYS Forge talk (Post)}
Two issues. Ive been struggling to get the user management the way I want it. I want to protect the device from unauthorized upload/download, but I do not want login requirement on webvisu. The combination that seems to work is to use "runtime device user management" while keeping the visu user management in "legacy mode"? Initially this seemed to work, but now images are not loaded when using direct access, while they are still shown if I access the webpage via Automation server. Im guessing its connected to the authorization changes? Anyone able to help out? Thanks Also, I read that legacy mode should be avoided, is it possible to use "runtime based visu user management" while keeping direct access to the webpage without login. System is a "Control for linux SL, version 4.20.0.0" Per

Post by ryandmg on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
Hey Everyone, I'm having a bit of a struggle finding settings that will reliably maintain a connection between the webvisu and a touchscreen client. Every so often the HMI disconnects and will perpetually display the red spinning arrow with the "Error Happened, Will resume automatically" text. Power cycling the HMI to force a reconnect will re-establish comms. It seems to happen during periods of inactivity if that's a clue. From what I've gathered so far this seems to have something to do with the webvisu update rate, buffer size as well as the visu task scan rate. We first tried the default settings as follows: Webvisu Update Rate: 200 ms Webvisu Buffer Size: 50,000 Visu Task Scan Rate: 100 ms Priority 31 Other Tasks for Reference: Main Task Scan Rate: 100 ms Priority 1 Alarm Manager Scan Rate: 50 ms Priority 31 Ethercat Task: 4 ms Priority 1 This would disconnect some what regularly. We then made the following changes to try and stabilize: Webvisu Update Rate: 150 ms Webvisu Buffer Size: 75,000 Visu Task Scan Rate: 75 ms Kept other tasks the same. This seems to disconnect even more frequently. Also for reference the network is very small and only consists of the PLC, a small switch and the HMI. We're also not controlling frames from outside the visu program itself. The frame changes are all done natively. Any suggestions to get this to stop disconnecting? Oh and whatever the issue is the log does not record it. Figured I would ask here before opening a ticket. Thanks in advance for your help!

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

Post by dkugler on User management ^{CODESYS Forge talk (Post)}
If the PLC is equieped with a USB socket it's possible to copy the user management file via IEC code to a USB stick and restore it at the new plc. The file is located there: /PlcLogic/visu/app_visuusermgmtdb.csv I use this to reset the user management to default in case of the customer has changed passwords and lost it.

Post by timvh on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
A Task is a standard IEC 61131-3 object, so logically that you can export the VISU_TASK. A visualization is no standard IEC 61131-3 object, so not compatible with other IEC tools. Just use the standard export / import functionality. These files are not IEC compatible and can only be used in CODESYS. But these do support visu objects.

In your soft plc folder, there is a file called targetvisuextern.cfg. Open this with a text editor to change the settings. Remove the semi-colons in front of the lines to enable your custom window settings. WindowType=0 means you will get a moveable window. Save the file and restart the soft PLC to enable these settings.

This came up again today, so I'll post the fix for future reference. Happens with Schneider Machine Expert 2.2 and M262 controllers. Add this bit of code to a program called from the visu task //disable "VisuFbFrameBase.SetInputPositionData" log messages, which fill up the logs IF VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.GetListenerCount() > 0 THEN VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.RemoveValueChangedListener(VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.listenerForOnValueChanged); END_IF

Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Thanks for this - I have now been looking in to just having an extra (non-RTE) runtime on the same machine, as you suggest. I will probably proceed this way. Even though it still seems very odd to me, that variable exchange to a different runtime is easier than between applications on the same controller. There will be some fun with the licensing, it seems. Does anyone know if it is possible to specify which license container/specific license the runtime is going to use at runtime. Let's say I have two available licenses with different resources available, for example one license allows multicore and multiple EtherCAT channels, but not many visu tags (for the RTE). Another with less resources but a lot of visu tags (for the Visu controller). Let's say the program in one of the controllers could be fully licensed by either of the two available licenses, but picks the 'largest' first. A bit later, the larger application starts, but is left with the smaller license.. How can I make sure that the 2 runtimes select the right license at startup?

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne
