Post by mejak on Raspberry Pi USB HID RFID Reader - read ID in plc program

(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

Hi aniket-b, If you save the library as a compiled library you are not able to see the source code. When the end user tries to view inside the object, CODESYS will give a notification that the source code is missing, see attachment. In short if you don't send the source code, it will not show.

Hi guys, I am new to the Visualization. I am having a problem. I have multiple web-panel to use webvisu. I have my software dowwloaded into the one PFC200. There are 3 screens connected to it. I noticed that if I switch page/visualisation on one of the screens, the others will change as well. Three screens are with different URLs that I set in the software. Is there any method to make them independently ? Kind regards, Jin.

Hello everyone, I installed my liscence on my raspbery but I can't reactivate it after installing it on a new SD card because the old one was broken. I get an error message 10957.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

I/O Drivers

Hi, Ingo! Im very glad to see this page and your work. But I cant understand many of things. For example: in the IoDrvFb: cDriverName In the device description I see only libname, and Device name, what the drivername ?:) and many other fields I dont know what to set and how to start tesing them and what for my attention the first time. And other fields in the iodrv system libs. Where I can learn this? I need to understand every step, every field in the xml and in the Fbs. Thanks you! And what are u thinking about book of codesys that written by Gary Pratt? Is there information I need about system libs and drivers? Thank you :)

Hello, Recently I upgraded to 3.5.19.50 and have been having errors/issues when doing a download/online change. The message as seen in the attachment pops up. The file in the path is different every time. However when I login again afterwards all works fine. This issue does not happen on older versions. Any clue what the issue could be? I did an reinstall/repair but the issue reappeared again... Thanks in advance!
