On a website i can get the energie price. But how does that work in codesys? There is a video of Rest client. But i can find the HTTP library. If i type on my browser : https://enever.nl/api/stroomprijs_vandaag.php?token=ANWB i get {"status":"true","data":"Please provide a valid API token. More information at https:\/\/enever.nl\/prijzenfeeds\/","code":"2"}

Post by rjonker on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

Post by janderson on OPC UA Server limitations, large array crashes runtime ^{CODESYS Forge talk (Post)}
What are the limitations of the OPC UA Server? I am trying to get data off my PLC that is acquired at high rates (~50k samples/s) so I am storing them in arrays and trying to get the arrays off the PLC. When I attempt to read a ~200k element array through OPC UA the server and runtime crashes (requiring tools -> update linux arm64 -> start runtime). Is there a better way to get highspeed data off? The ACDatalog library seems a bit irritating to use so I would prefer to go through OPC UA.

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne
