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

Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Dear @gseidel, @tk096, I noticed that with SoftMotion V4.18.0.0, if a new axis is added to the project, the ramp type selection defaults to "Quadratic". In all previous versions, the velocity ramp type selection was "Trapezoidal". This causes some unexpected issues in projects with SoftMotion version V4.18.0.0 for newly created or newly added axes to existing projects. Is it possible to reconsider this situation in the next update and set the velocity ramp type to "Trapezoid" by default again? Best Regards, Imdat

Post by remcoborghuis on C0032 Error to type Pointer to IoConfigParameter ^{CODESYS Forge talk (Post)}
Hi All, I'm using codesys on a raspberry PI. I use V3.5 SP18 Patch 2 development system and codesys for raspberry pi 4.8.0.0. Sometimes when I build the project I get error messages C0007: Expression expected instead of ',' and C0032: Cannot convert type 'Unknow type: '!!!'ERROR'!!!" to type 'POINTER TO IoConfigParameter'. I can't click on the message to bring me to the fault. After I do a "Clean all" the build finishes successful. Anyone who can help me with this problem? Thanks! Remco Borghuis
