Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we...
Thanks for the help! Everything now works as expected.

it is just a precompiler error, login an start the application. Works.This will be fixed hopefully to next version.

your are sending as a WSTRING which is UTF16, but your receiver is interpriting as UTF8. Change the receiver to use UTF16, or better change your sender to convert to UTF8. You publish the entire storage space (SIZEOF) Instead of the number of bytes of actual text (StrLenA) try using utf8JsonData : STRING(2000); JSON.Stu.ConvertUTF16toUTF8( ADR(wsJsonData), ADR(utf8JsonData), SIZEOF(utf8JsonData) ); and change your publish to mqttPublish( mqttClient:=mqttClient, pbPayload:=ADR(utf8JsonData), udiPayloadSize:=To_UDINT(JSON.Stu.StrLenA(ADR(utr8JsonData))),...
I am trying to figure out how to get a JSON payload to properly publish to my MQTT Broker. I am able to generate JSON using the examples from Codesys, but when I send that payload via MQTT there are characters that are extra or not recognized by my MQTT client. Any idea what could be causing it? PROGRAM PLC_PRG VAR hostname: STRING := 'localhost'; port: UINT := 1883; topic: WSTRING(1024) := "testing/"; payload: BYTE; factory : JSON.JSONDataFactory; eDataFactoryError : FBF.ERROR; pJsonData : POINTER...
After a project is opened and I have done some changes, I want to start the build or code generating process by a python script file. After the build is done I a Windows sound/beep should appear. Anyone has an example or hint how the .py file has to look like? Thanks!
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.
