Hello, If you have done all steps that are written in this thread, you have a faulty CPU. Here they are again: Test PPI cable with other PLC. Set PLC in Stop with switch. Select search all baudrates. Local adres should not be 2,try different adresses. Disconnect extention modules. Try Wipeout Regards, Marcjan |
Problem solved? |
