Post by sigurdrb on OPC server in "Communication manager" ^{CODESYS Forge talk (Post)}
Hi! I was thinking of switching the OPC server config from "Symbol Configuration" to the "Communication manager" in the device tree. I Have a lot of arrays of structs that I have previously declared in the "Persistent Variable" object in the device tree. It seems as it is not supported to directly expose persistant variables to the OPC server like the "older" way of doing it in the symbol config. Is this correct? Do you recommend to just do it the old fashioned way, or should I edit the structure of the global variable list / persistant data / OPC server and set up the OPC server from the "Communication manager" object?

I would expect that this is more or less Bookworm related - the GPIO access is different now - and need to be adapted

Post by hemuv on Dialog Open ^{CODESYS Forge talk (Post)}
I'm programming an HMI for a machine. I want to log all the parameter's changes (used text field for displaying and changing) for particular User levels. Created a Numpad and want to log oldvalue and Newvalue on 'ok' Button press. To retrieve the oldvalue, i check if the dialogue opened is my Numpad, Then I retrieve the dialogue interface via GetDialogInterface(ADR(myNumpad)) --> numpadData.stVariableValue which contain my oldvalue and save it locally. Problem is sometimes i retrieve the data and sometimes not. Also observed when Numpad Dialogue is Opened, VisuDlgUtil_IsDialogOpen returns False in some cycles.Attached you will find my Project. please let me know what went wrong or if there is a better approach to collect old and New Value of a textfield. Thank you.

Post by timvh on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
You need to activate an individual license (ticket number) for each device. THe hardware of each device is unique, so you cannot copy a soft container from one device to another. This license can be installed in a local (wibu - codemeter) soft container, or you could optionally activate it on a hardware (USB) key. The benefit of the key is that you can easily move it to another device, nor does it get lost when you replace parts of the hardware of the device or completely overwrite the image. See: https://store.codesys.com/en/codesys-key.html

Post by ulvis on CFC Pages Cut&Paste is not working at its best ^{CODESYS Forge talk (Post)}
In the CFC page oriendted editor, if I copy some elements consisting of an input connector, some connected logic and an output connector and then paste this on a another page then the pasted elements get inserted with an offset to the right so that the rightmost connector falls outside of the page, in the grey hatched area. So far so good. Then I mark all the elements and try to drag them into the correct placement, collectively. THIS IS NOT POSSIBLE! I only get the "forbidden" icon tooltip. One has to drag & drop the INDIVIDUAL elements to move the elements around. What am I doing wrong?
