Hello, The 200 series do not have a battery inside, there is however a battery module to retain the data for a longer period. Do you have such module at CPU? I don't think it has anything to do with your communication problem. Make sure you have the right cable and settings, try again with PLC in stop mode. Regards, Marcjan |

Hello, Yes it's a 222, that's in the partnumber you mentioned Are there any modules connected or memorycard/baterry module placed at CPU? Remove all modules and start CPU again. Try all baudrate settings or select All baudrate (only works if pc adapter supports this) regards, Marcjan |

Hello, Well, if cable is correct and settings are o.k. only thing you can try is: Resetting the S7-200 to the factory default settings (WIPEOUT) For that you need a PC with Dos and the RS232 PPI adapter. Regards, Marcjan |
