Hi Gatto, Using version 3.5.21.xx, it is no longer possible to use Modbus function blocks (I make extensive use of these FBs.)as shown in the example. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_modbus_example.html The compiler detects one Modbus instance for each instance of the communication FB block. The example program above, although simple, reports 8 Modbus instances when compiled with the latest version. Codesys Support says that you must use fieldbus I/O mapping, but this will result in the loss of the ability to programmatically modify communication parameters. Sandro

Post by tobifenny on Modbus TLS Kommunikation ^{CODESYS Forge talk (Post)}
Ich habe eine Wallbox, die ich gerne per Modbus ansteuern würde. Die Normale Modbus-Kommunikation, um ein paar Werte auszulesen klappt auch. Wenn ich aber Zugriff auf bestimmte Modbus-Register haben möchte, benötigt die Wallbox ein TLS-Zertifikat. Das Zertifikat habe ich bereits erstellt und im Security-Sreen unter Eigene Zertifikate hochgeladen. Weiter komme ich aber nicht mehr. Wie baue ich eine TLS-Verbindung mit der Waalbox auf? Vielleicht hat das ja schonmal jemand gemacht und ein Beispiel für mich. Ich bin über jede Hilfe sehr Dankbar!

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks! As far as I can see, the client can only send words. And on the server side there are an array for each of the functions: bool for coil and discrete, word for holding and input registers. I assume I can use holding register, then use bit mapping on the words instead of coils. But I really want to use the FC15/coils.

Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.
