Hello, Are you sure that with wipeout.exe wasn't helpful? I mean do you use the cable before to connect to other CPU? What are the settings in PG/PC Interface? When the RUN light is ON do you have some outputs active there? best regards, Hristo Mihalev |

Hi, all My PLC model is S7-200CN AC/DC/RYL ( 6ES7 212-1BB23-0XB8 ) and cable is RS232/PPI Multi-Master Cable (6ES7 901-3CB30-0XA0) actually, I've got USB/PPI too. Problem as shown in Fig01.jpg (SF/DIAG=RED, RUN=GREEN) can not connect to CPU via USB/PPI or RS232/PPI on Step7MicroWin SP7 It's not because of "Language" trouble beacuse another one of my CPU S7-200CN is connected also upload and download. So, I use wipeout.exe but it seem doesn't work as shown in wipeout1.jpg then I connected my CPU to module EM277 PROFIBUS DP as in Fig02.jpg and I tried wipeout.exe again, it's done well as shown in wipeout2.jpg but problem not solvedSF/DIAG=RED, RUN=GREEN and not connect. Thank you.

Hello, After successfully "cleared" of CPU, can you connect using PPI cables to the CPU? Best regards, Hristo MIhalev |

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? |
