gerard339 Posted August 13, 2019 Report Share Posted August 13, 2019 Hi, I have to install my program every time I turn on my v570. I don't have a SD card installed - would it solve the problem if I installed a SD card? Gerard Quote Link to comment Share on other sites More sharing options...
AlexUT Posted August 13, 2019 Report Share Posted August 13, 2019 Hi gerard339, Please review Help->Downloading/Uploading a Project. It explain your situation. 1. Check backup battery compartment. Battery should be installed right way. *New PLC (from the box) include backup battery in plastic bug. 2. Check battery voltage. For new battery it should be between 3.2V...3.1V. 2.8V is critical minimum. *When measure battery voltage by digital multimeter, there is no load, and even bad (discharged) battery will show voltage in accepted range.. 3. Check SB 8 - Battery Low. If it is '1', battery should be replaced. 4. Use "Download All & Burn" download option. *PLC registers content may be random, but project will run. B.R.
