    Hello All, I am using a PLC based on raspberry Pi and the Codesys version I am working on is Codesys SP17 Patch 3. I have connected an USB drive to the Rasp Pi and I am given a file patch 'ls -al /media/pi' that I have to type somewhere in Codesys so that I can store results in this path. I am new to both Rasp Pi and Codesys. I am figuring out where to write this command. Can anyone help me? Or is there any other way I can access the USB drive connected to Rasp Pi using Codesys? Best Regards!

    Hi all! I am using a PLC that is based on Raspberry Pi. My Codesys version is SP17 Patch 3. My question is about Runtime license. I will be buying the license but what I want to know is will I have reload all the libraries, GPIO, I2C and Raspberry Pi update configurations all over again because I bought a runtime license now? The reason I am buying runtime license is because after 2 hours the Raspberry Pi hangs stating there is an error in web visualization. On studying about it I came to know that...

    Hello All, I am using Raspberry Pi based PLC with Codesys SP17 Patch3. I am planning on changing the visualization screen when an Input that is connected at GPIO4 of raspberry Pi is pressed. Is there a way I can do it? I am confused. Thanking you all!

    Hi, I tried your code and oh my god, you were right! It worked. YAY! I am so glad it worked because I was trying hard for the past 4 days but nothing clicked. However, I observed that to retain the changed values, the raspberry has to be shutdown properly instead of direct plug off. I mean when I directly turned off the supply and switched it back on, the pi showed me the previous values but not the changed ones. So, I shut it down properly and it worked!! Thank you so much for sharing this critical...

    Hello all, I have a plc based on raspberry pi. I use Codesys v3.5.17.30 version for my programming. I want to create a variable whose value must be retained in the memory so that the plc must remember it even after the power failure. I often work on Persistent Variables in Codesys for the same and it works but for some reason with this raspberry pi hardware, it doesn't work. Could someone please help me how to get this done?
