Post by ganassa on Custom colors in Ladder diagrams? ^{CODESYS Forge talk (Post)}
How can I change the default color - blue - for active lanes, contacts and coils? I'd like a lighter color. After having failed in finding a related option in the IDE, I've looked at the "Default.editortheme" file in CODESYS' directory, but couldn't see any related option. Thank you

Post by paulpotat on Where can I find a list of all available runtime configuration parameters ? ^{CODESYS Forge talk (Post)}
Hello, I was wondering if there is a list somewhere of all the parameters that can be used inside the "/etc/codesyscontrol/CODESYSControl_User.cfg" configuration file ? I searched the documentation but didn't find anything. If it doesn't exist, that would be nice to have a little bit more documentation about this file :) Thank you for your help, BR

Hallo Herr Schwellinger, wenn ich den KNX Stack in Ihrem Pfad des Configfiles hinzufüge, funktioniert es. Vielen Dank für Deine Unterstützung! Es wäre aber sehr hilfreich wenn dies in dem KNX Dokument oder in der der CoDeSys Hilfe mit drin stehen würde. Viele Grüße, Koeni

Hi. Raspberry pi 4 runtime. Runtime version 4.16, IDE version 3.5.21. Is it possible write new value for variable via modbus tcp or serial devices when both enabled? As I see - not. What can I do? It is terrible restriction.

Post by timvh on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
If you want to use the Test Manager, I prefer to start all the tests through the scripts of this manager. So open from there the projects, load it and run it. If you also want to use Python scripts to access CODESYS functionality, while executing a Test Manager script, then also start them from the Test Manager commands.

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?

Post by timvh on IECStringUtils.FormatDateTime ^{CODESYS Forge talk (Post)}
There has been a fix in SP21. I tried it in this version with the option "Use unicodestring" enabled in the Visualization Manager and it worked if the variables used for the function are declared as WSTRING variables wsFormat : WSTRING := "%t[HH:mm:ss dd.MM.yyyy]"; wsTime : WSTRING; IECStringUtils.FormatDateTime(cbpResult := ADR(wsTime), uiResultCapacity := SIZEOF(wsTime), cbpFormat := ADR(wsFormat));

Post by rajatdas2005 on Codesys Virtual control SL ^{CODESYS Forge talk (Post)}
Thanks once again. Right now the codesys virtual control sl docker is using the host ip itself not the docker ip. so the local host edge gateway was able to search the virtual plc. so you are telling me instead of local host edge gateway I should use the edge gateway docker version?

Now, for CODESYS v3.5 SP21 I can no longer find the "OPC UA Information Model Repository" entry to add as a command. In the "Tools" menu it is listed but greyed out, reporting "Plug-in is not available". So how do I add the Plug-in?

Post by mqi2r on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
For anyone with this issue, you may need to: Open the text list properties (right-click the text list once you create it). Select the Text List tab. Change the Download by option to Visualization. I was fighting this for so long. Once you do that, you should find your text list appears in the drop down when editing a visualisation.

ich meine mich zu erinnern, dass ich schon FB's hatte, die Fehlermeldungen mit löschen des Enable/Execute Bits abgelöscht haben. Dann würde bei dir sobald das Error Bit gesetzt wird, nichts mehr drin stehen. Vielleicht wäre es ein Versuch wert, den String vor dem zurücksetzen des Execute in eine Variable zu speichern, ob dann was drin steht und danach erst ablöschen?

This is from sometime ago but below might help someone else; this could be done via POINTERS. Make sure you protect for NULL pointers etc if you take this approach. // DECLARATION myEnumValue : enumMyEnum; u8 : USINT; pmyEnumValue : POINTER TO enumMyEnum; pu8 : POINTER TO USINT; // CODE pu8 := ADR(u8); pmyEnumValue := pu8; myEnumValue := pmyEnumValue^; // dereference the pointer

Post by eschwellinger on TargetVisu option missing in IDE ^{CODESYS Forge talk (Post)}
It is not needed to add Targetvisu connector - for using the TargetVisu for Linux. The reason is - TargetVisu for Linux is basically a remote TargetVisu which could connect to any CODESYS plc not only the loacal one - therefore only a Webvisu connector is needed to have it work. & it seems a bug with this anoying update proposal.
