Hello everyone, I am facing an issue when working with MCP4725 and raspberry pi. I have downloaded the MCP4725 library from this forum. No matter what value I put in the MCP4725.xdacIn, the voltage is always at 0V. iDacValue : INT; MCP4725.xdacIn := iDacValue; (screenshot = Issue DAC 1) I am using a hardware that has raspberry pi core. The Codesys version I am using is Ver3.5 SP17 Patch3. I tried putting 97 in I2C Bus Parameters for MCP4725 (screenshot = Issue DAC 2) based on a conversation thread...

Hi! I am facing a similar problem like you. I have downloaded the MCP4725 library from this forum. No matter what value I put in the MCP4725.xdacIn, the voltage is always at 0V. iDacValue : INT; MCP4725.xdacIn := iDacValue; (screenshot = Issue DAC 1) I am using a hardware that has raspberry pi core. The Codesys version I am using is Ver3.5 SP17 Patch3. I tried putting 97 in I2C Bus Parameters for MCP4725 (screenshot = Issue DAC 2) but still I am facing the same issue. I have been using ADC in I2C...
Hi, Yes, reinstalling the OS of the plc is also a way. Good to hear that your issue is resolved. :) Have a good day! Best Regards!

Hello All, I have bought two raspberry pi based plc units sometime back. Last month I bought a runtime license 'Codesys Control for Raspberry Pi SL' and got an activation ticket from the team. I activated the license and installed it in one of the raspberry units which was successful. Now this morning I tried to load the same license in the other unit but I got an error '10957 [10957] - Ticket contains no open licenses for this firmcode' Can anyone tell me what it means or what am I supposed to do?...
First of all, I am so sorry for late reply. I just saw your message. Yes, I was able to fix it. But it was with Codesys V3.5 Patch 3 SP17. However, I don't think this issue has anything to do with codesys version. Here is what I did. Since my plc is based on linux system (raspberry pi), I had to first stop the plc then remove a few files and then start the plc again. The detailed description is given below. I first went into file manager in pi. There, I navigated through the folders in the path /var/opt/codesys....
