Post by jonhmoafa on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge talk (Post)}
When the client disconnects (by setting ClientConnect := FALSE), the server still holds an active connection handle (hConnection), which causes the server to reject or mishandle new incoming connections from the same client Geometry Dash Lite IP and port. The key issue: You are not cleaning up the old connection on the server side. So when you try to reconnect from the client side: A new TCP handshake is attempted. But the server might still have the previous session open (from the OS/socket library's view), and so it gets confused or fails to accept it properly. This leads to client timeouts.

I would definitely try using the "Reconfigure" function block from "CAA Device Diagnosis@ library. https://content.helpme-codesys.com/en/libs/CAA%20Device%20Diagnosis/3.5.17.0/CAA-Device-Diagnosis/Function-Blocks/Reconfigure/Reconfigure.html#:~:text=This%20function%20block%20reads%20and,take%20effect. Although I have not tried it with Modbus, I had great success with EtherNet/IP, Profinet and EtherCAT. You can also have a look at the other functions in this library. There are useful functions to help iterate through all the nodes under a master node.

Hi naci, because this is a english forum it increases the chance to get help a lot if you translate your questions into english before posting :-) happy coding!

Hello If you uncheck 'Auto restart Communication', it will try once and never again. You can manually reset the slave if needed : Slave.xReset (or something similar) Or I have a ModbusRTU library if you want to try it.

Project Members: aliazzz (admin) Applied Design Patterns in CODESYS-V3 Remember Further Reading Patterns of Ladder Logic Programming The -Abstract Factory- Pattern The -Builder- Pattern The -Command- Pattern The -Decorator- Pattern The -Observer- Pattern The -Proxy- Pattern The -Singleton- Pattern Applied Design Patterns in CODESYS-V3 These design-patterns come from various sources all around the internet. I decided to study and rework / translate them into Codesys V3. The patterns are ideally suited for selfstudy purpose. Any new contributions are heartly welcome! Kudo's go out to the original posters! Remember No matter what fancy pattern you throw at it, keep it "simple and stupid" and ask yourself "do we really need it?". Allthough design patterns may ease your life significantly, the simplest solution is always the best solution! Further Reading If you need any further reading on these topics, I suggest you visit the following page by gabr42, 'The delphi geek'. It contains many many useful links on for OOP related topic. A SOLID (pun intended) starting point for all! https://www.thedelphigeek.com/2019/04/deep-dive-into-design-patterns.html Now, let's dive into some CODESYS patterns curated and collected from around the web; Patterns of Ladder Logic Programming The 'Patterns of Ladder Logic' translated to CODESYS 3 LD Function Blocks Original Poster: Scott Whitlock: http://www.contactandcoil.com/patterns-of-ladder-logic-programming/ https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/Patterns%20of%20Ladder%20Logic%20Programming/ The -Abstract Factory- Pattern The 'Abstract Factory' Pattern, converted from TwinCAT3 to CODESYS 3 Original Poster: Stephen Henneken: https://stefanhenneken.wordpress.com/2014/11/16/iec-61131-6-abstract-factory-english/ https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Abstract%20Factory-%20Pattern/ The -Builder- Pattern The 'Builder' Pattern for CODESYS 3 Original Poster: Armando Rene Narvaez Contreras https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Builder-%20Pattern/ The -Command- Pattern The 'Command' Pattern, converted from TwinCAT3 to CODESYS 3 Original Poster: Stephen Henneken: https://stefanhenneken.wordpress.com/2016/12/07/iec-61131-3-the-command-pattern/ https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Command-%20Pattern/ The -Decorator- Pattern The 'Decorator' Pattern for CODESYS 3 Original Poster: Armando Rene Narvaez Contreras https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Decorator-%20Pattern/ The -Observer- Pattern The 'Observer' Pattern for CODESYS 3 Original Poster: Armando Rene Narvaez Contreras https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Observer-%20Pattern/ The -Proxy- Pattern The 'Proxy' Pattern for CODESYS 3 Original Poster: Armando Rene Narvaez Contreras https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Proxy-%20Pattern The -Singleton- Pattern The 'Singleton' Pattern for CODESYS 3 Original Poster: Armando Rene Narvaez Contreras https://forge.codesys.com/prj/designpatterns/code/HEAD/tree/Tags/The%20-Singleton-%20Pattern

Hi Lamine97, if you are struggling with the LD implementation it would be more helpful for us to see that code in a screenshot.
