Post by jeroenaero on Autostart Targetvisualization 4.16.0.0 doesn't work on Linux device ^{CODESYS Forge talk (Post)}
Hi, How can we configure autostart of TargetVisualization on the remote device? The device is a Raspberry PI CM4 with PIXEL Desktop on display. I installed Targetvisu for Linux SL 4.16.0.0 on it. After each restart of the Raspberry PI CM4, we have to start Targetvisu fot Linux SL manually. i tried the step on this page: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_target_visu_for_linux.html but i don't get it working

Post by robpqs on Visual error with cut/shredded texts ^{CODESYS Forge talk (Post)}
Hello, This is an old topic but it might help. This can/should be solved by either of the solution below 1. disabling the "Support client animations and overlay of native elements" option in the visualization Manager (which is handy) 2. disabling the "Hardware acceleration" of the browser. Saw it happening on some clients/PC and on other it works fine with the same webvisu... (Version 3.5.19.20 with visu package 4.4.0.0) Hopefully it will be fixed it in a next release. I haven't tested the 4.5.0.0 visu packages yet. RP,

Disable the setting "Support client animations and overlay of native elements" in the Visu Manager. Activating this setting should also set a compiler define (GENERATE_OVERLAY_VISU). Maybe the compiler define is set and the feature is not activated in the visu manager or or the other way round.. rightclick the Application -> Properties -> Build https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_properties_build.html

Post by rabaggett on No Visu on RasPi ^{CODESYS Forge talk (Post)}
OK, I got this to work as shown above in mos89p's comment. What I did: Tools/Update Raspberry Pi. Reloading the runtime seems to have solved the web problem. I can view the visualization on the Pi and laptop using a browser as shown above. Thanks! But Isn't the visualization supposed to take over the screen of the Raspi? When I run visu projects on Windows or Wago, the visualization shows on that device's screen by default.. But this is not happening in this case

By using the CAA FILE library (FB FILE.Open) (raspberry pi, codesys 3.5.19.0) I always get the error FILE_OPERATION_DENIED The file exist, it has r/w/x access and path is correct... Some idea to fix it?

Hello everyone, I am using SP19 patch 2 on a Kunbus device with runtime package 4.9.0.0. I am having the same problem as mentioned above. With the FB File.open I get the FILE_OPERATION_DENIED error. I have also tried the path /var/opt/codesys/PlcLogic. Any advice? Chris

When I load the SMC_GroupWait command twice in a row into the buffer an error occurs when I try to MC_MoveLinearRelative in the dynamic coordinate system. If I use MC_MoveLinearAbsolute in the dynamic coordinate system, it still works

Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

You cannot create an array of Programs. Create a Function Block for this purpose instead of a program. You can create an array of FB instances and call each instance in a loop.

Post by tk096 on Creating Custom Kinematics ^{CODESYS Forge talk (Post)}
Hi, a few questions that you can check regarding your kinematics: * Does your kinematics FB implement the interface ISMKinematicWithInfo2? * Does AxesToCartesian(a, out f) -> CartesianToAxes(f, out aCompare) result in a=aCompare for random positions a? * Do you return a valid rotation matrix f.mR (SMC_Matrix3) in AxesToCartesian()?

Did you create a certificate on that device already? Go to the menu View - Security Screen and check the certificates on the device. There should be one for your webclient FB.

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.

Die im FB 'zeitschalter' deklarierten Variablen sind nur lokal gültig und global nicht sichtbar. Deshalb kannst du in'PLC_PROG' nicht darauf zugreifen. Hier must du entweder eigene Variablen deklarieren oder globale Variablen in einer globalen Variablenliste (GVL) anlegen. mfg Reinhard

Post by fless on See only variable ^{CODESYS Forge talk (Post)}
either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco
