Post by george32 on Learning ST in an object-oriented way. ^{CODESYS Forge talk (Post)}
Dear all, I am currently creating a program in the ST language. Because the program is starting to grow nicely I would like to switch to a more object-oriented way of programming. (Like for example in Python). By surfing the internet I found out that Function Blocks is the best method for this. Now I would like to delve further into this, with all the possibilities that Function Blocks have only I cannot find a clear course, explanation of what everything is around the function block thing and how to approach everything. I find the standard documentation around Function Blocks rather abstract and the examples are minimal. Therefore I am looking for a page/course/document explaining object oriented programming in Codesys (or other PLC programming environment). Do you have any recommendations on this?

DO NOT use the same username and password in Codesys as your default Rpi OS admin user on the Pi.

P.S.: I'd prefer a lighter color because the default blue makes it difficult to tell a normal contact vs. negated, etc.

Post by joerg-schneider on SVN: "Include externals" Fehlermeldung ^{CODESYS Forge talk (Post)}
Ich habe eine Bibliothek unter Subversion verwaltet und verwende Teile davon in anderen Subversion Projekten mit "Include externals". Wenn man die Bibliothek mit "Copy (Branch/Tag)" kopiert, lässt sich die Kopie nicht mehr mit "Include externals" in anderen Projekten einbinden. Es kommt eine Fehlermeldung, dass ein Pfad nicht gefunden wurde (siehe Anhang). Auch wenn man das Bibliotheksprojekt direkt auf dem SVN Server kopiert (mit Tortoise SVN), kommt die gleiche Fehlermeldung beim Versuch die Kopie mit "Include externals" in anderen Projekten einzubinden. Ich nutze Codesys 3.5.20.60 mit Codesys SVN 4.6.2.0. Wie kann man Projekte auf dem SVN Server so kopieren/verschieben, dass sie später mit "Include externals" in anderen Projekten verwendet werden können?

Post by timvh on Dynamically enabling/disabling Modbus slave devices in runtime (performance issue with timeouts) ^{CODESYS Forge talk (Post)}
As far as I remember, the Reconfigure functionality doesn't work for Modbus devices. But... Each Modbus device in your device tree has a name. You can set the property "Enable" of this device to FALSE to stop communicating with it. So if one of your Modbus Slave devices name is "MbSlave1" in the device tree, then in your code you can set the Enable to FALSE to let it stop communicating: MbSlave1.Enable := FALSE; Please let us know if this worked on your controller with your application and your CODESYS version. Alternatively you could use the ModbusFB library. See: https://forge.codesys.com/prj/codesys-example/modbus/home/Home/

Post by bruceae on Special Characters ^{CODESYS Forge talk (Post)}
Hello, I am fairly new to the codesys environment. Is there a reference chart that I can look at in order to write special character in a string? The Special characters that I need to inclue inside the string are as follows; Null Bell Carriage Return I have a TCP_Write command that I am sending to an external device. In order for that device to function properly it needs to see the string with the null and bell characters as the header, followed by the desired command, terminated with the carriage return. Any reference sheet or how to write this in the actual string would be greatly appreciated.

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Dear Forum I have the following config: Codesys_IDE 3.5.20 Codesys_Virtual_Control 4.13 Codesys_License_Server 4.13 I know these are not the newest versions, but in my mind these should work. I have the same problem here. I have the license server installed on the host, and in the docker container(Codesys virtual control) I'm able to ping the license server. In the /conf/codesyscontrol/CODESYSControl_User.cfg I have added the following config: [CmpCodeMeter] EnableNetLicenses=1 LicenseServer.1="ip address of the host" I have tried it via the wbm web-page. I can create new license containers over there, but still no luck. I also have tried to run the docker container with the -s "server_IP" command. I have searched for some tutorial's but I couldn't find it. If anyone has some clue or can give me a push in the right direction it would be very very welcome!
