Hi PLCnext Team, I’m getting used to Started Kit, and in the firmware installation step, i founded the firmware of my controller is 2019.1 and hardware is 02. But I can’t find them because it’s too old. So could you tell me which firmware version should I install? My PLCnext Engineer’s version is 2021.3. Thank you!
Hello, You should always try to run the latest long-term (LTS) release, or else the latest feature release. At the moment these are both identical (version 2021.0.5). The release stragtegy is described in the Info Center, here: https://www.plcnext.help/te/About/Releases.htm The instructions for updating the firmware are also described in the Info Center, here: https://www.plcnext.help/te/WBM/Administration_Firmware_Update.htm
