Good afternoon team I have two Siemens S7 400 PLCs, the no.0 was as master and when it failed, I found the backup no.1. To the no.0 I flashing all the led, to make the connection with step7 and make the diagnostic buffer appears as unavailable. I tried to connect unsuccessfully attached the (image shown), when connecting to PLC 1 indicates that due to a voltage variation took control, I continued to insist on the connection to make the diagnosis of buffer and mark no Diagnostic information (attached image). Do you recommend: That I replace the CPU? or Reset the flash drive, if so you have the procedure to do so. I appreciate your cooperation. Greetings...
