Post by adaml on ScriptEngine - execute "Export -> Bootproject and firmware (SD Card)" from python ^{CODESYS Forge talk (Post)}
Hi everybody, recently I was checking how many time consuming manual tasks I can perform with python scripts through ScriptEngine. I have in the project many devices and currently I export bootprojects for them by right clicking on Application, then go Export -> Bootproject and firmware (SD Card) and then point folder where files should be exported. It's fine if project has few devices, but I have some of them with over 30 devices and manual clicking like that is very time consuming. How can I do it with python script? So far I found "create_boot_application" method from Application object (taken by projects.primary.find('Application', True)) but it only generates .app and .crc file instead of full structure to store on SD card (FIRMWARE, USERDATA, SDCARD.INI, Version, Version.txt.sig). Should I use some method to control user interface? Best regards, Adam

Post by phoward131 on Alarm Table Filtering ^{CODESYS Forge talk (Post)}
I am having trouble getting the alarm table filtering to work. I downloaded the alarm filter latch example project and ran it on the local Codesys Control Win and the filters worked fine. I am trying to replicate it in my project and everything seems to be set up the exact same way and every time I turn on the filter, it shows no alarms. I even started a blank project and just copied in elements from the example project so that it is exactly the same and when I attempt to filter, it again shows no alarms. Could there be some project settings I need to adjust to make this work? I have attached my project with elements copied from the example project and filtering is not working.

no nowadays I would recommend connect by name. Which is the default I guess since some versions.

Post by akfarslan on The application does not exist on "device" ^{CODESYS Forge talk (Post)}
Dear All, I am using CODESYS 3.5.19 SP4 with a PLC device. When I try to download my program to the device, I get the error: "The application 'Application' does not exist on the device". Additionally, after restarting the device, the program does not run automatically. When I connect to the device using WinSCP, I can see that the application.app file is uploaded to the root directory, but the device does not automatically start the application. I tried using the Create Boot Application option, but it does not resolve the issue. Is there another configuration step I am missing? How can I fix this problem? Thank you, Best regards,

Post by pernockham on Slider instance value when accessed through "execute ST-code" ^{CODESYS Forge talk (Post)}
I have a time which I want to modify with a slider. I have confirmed it is possible to set the value of the slider by to_real(time) (I can see that the slider changes according to 'my_time_value's value). Slider variable: to_real(my_time_value); However I fail to access the current slider instance value when I want to write back the value as time (write to a variable will not work as I need a type-conversion before assignment). my_time_value := to_time(slider-instance-value); I tried with this^.? but could not see anything interesting and also THIS^.GEN_Instance.? but nothing resemble what could be the sliders value. Anyone that knows? Thanks!

I think this will not work. I reworked and used an int as source instead.

Post by tyleretn on Codesys 3.5 SP18 P4 Freezing on Library Update ^{CODESYS Forge talk (Post)}
I have created a library with both code and visualizations to be used in multiple other projects. After I update the library version into the library repository, I have much difficulty updating the version into the main project. I can always update the library version in the Library Manager just fine. My issue, is sometimes Codesys will freeze when opening the visualization that uses the library visualizations. Sometimes it opens, but freezes when I try to access the library visualizations from the Visualization Toolbox. I try letting Codesys run for upwards of 4+ hours and it is stuck in this state. On very rare cases I have no issues and can continue with my work. I haven't found a consistent reason or work around. Has anyone else had this happen?

Post by clarenced on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I got this working using OPC UA. In the logic application I just added a Symbol Configuration. In the HMI application I added a Data Sources Manager and OPC UA Data Source. The one thing I don't like is the way the tags end up being named in the HMI application. In the logic application I have a program named PLC_PRG. It has a variable named testDINT. In the logic application the name I get for this variable is DeviceSet.CODESYS_Control_Win_V3_x64.Resources.Logic.Programs.PLC_PRG.testDINT. This is very long and looks like it could change if I used this on a different device type. Any ideas how I could get this name shortened down to just PLC_PRG.testDINT like it is on the Logic application?
