Recently I get a S7-1214C ac/dc/rly plc, whenever i connect ac power all the indicating LED i.e 'Run/Stop , Error & Maint' start to blink. I can't upload or download any program. In TIA Portal V13 only accessible node is not shown. Anyone encountered and solved the same problem? Please help me. Thanks in advance..
