Post by manuknecht on Detect "Cancel" Press in FileOpenSave Dialog ^{CODESYS Forge talk (Post)}
When using the FileOpenSave dialog and using the Visu_FbFileListProvider FB as an In/Output I could not manage to detect the difference of pressing the "Load" button on the dialog vs. pressing the "Cancel" button. In both cases, the selected file is updated if the dialog is closed when checking using the Visu_FbFileListProvider.GetSelectedFileName() command. How can I prevent reading or writing of a file when the "Cancel" button was pressed?

Post by taqamert on CANopen PDO Issue with Pressure Sensor in Codesys ^{CODESYS Forge talk (Post)}
Hello everyone, I am using an IFM CR0303 model PLC, which has a tilt sensor and a pressure sensor connected via CANopen. Both sensors are from the same brand (ATEK). I can read data from the tilt sensor without any issues, but I am unable to read data from the pressure sensor. I have added the EDS file in the PLC configuration and adjusted the node-ID settings. When I check with the PCAN-View application, I can see that the selected PDOs are coming through, but the data is not reaching the Codesys side. What could be the issue, and what can I try to resolve it? Can anyone help me?

Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program ^{CODESYS Forge talk (Post)}
Hello, I have an RFID reader that is detected as a keyboard. While looking for information, I came across examples using visualization. I would like to read the ID without visualization or external code in python, only in PLC. I found on the forum that you can try reading directly from potru /dev/... https://forge.codesys.com/forge/talk/Runtime/thread/24b3527036/ How to read values directly in codesys? Or maybe there is another solution? Best Regards

Post by rabaggett on Reading Named Pipes in Linux Is there a better way? ^{CODESYS Forge talk (Post)}
I have a Python program that will handle things in my application such as VISA over IP and Telnet control of instruments. I want the main control and HMI in Codesys. My problem is communication between the two. I have looked at several ways to accomplish this, and settled on having the Python program create two named pipes, one to send information to Codesys, and one for Codesys to send information to Python. The information would be packetized with \n for end of packet.. Seems simple. I think the named pipes method should work, but file reading in Codesys using the CAA file library starts to get difficult when the file is never ending, as in this case. Before I spend too much time making something that may be fundamentally flawed I want to ask. Is there a better way? Is there a way to read the file 'one line at a time' which might solve my never ending file problem? Thanks!

Well I created a user as Admin, gave access rigths to the file but still can't read the files in the plc it gives the same error. I guess is something to do with plc itself.
