indication lamp flashing )for along period on the cpu also(SF) fault lamp illuminate for
along period and the HMI on the profibus network has power but no any data or
program on it
AFTER CHECK the message was
DP slave not accessible by means of the bus
and by the check i found the status of the DP slave was:
module configured but not avialable, preset / acutal mis match (inserted and configured module type are not the same)
but over all the main program for machine still functioning and the machine in service

Hardware Config

Check your Hardware config.

The model numbers of cards must be the same in the field as per your Hardware configuration.

Check your Hardware config.

Apparently, according to the second message (bmp), the module is configured but not available.
Mismatch is the key word!
Your actual CPU part number is different than the part number configured.
See post #2. Check hardware configuration.
