Posted 20 Mar 2019 Hi everyone, My plc got a fault, then I power down the PLC => remove the battery => Turn on the PLC until fault led off => Power down the PLC once again => Mount the battery and turn on the PLC. After that, I cannot connect the PLC via either Ethernet or COM port. Please tell me how to factory reset the PLC. Thanks in advance, Share this post Link to post Share on other sites
