Backplane bus supply of the ET 200SP is not OK
Flashes
Module reintegratable diagnostic event has been resolved and the module or channel is awaiting reinte-
gration. This can include the following events:
• Reintegratable over-voltage error
• Reintegratable under-voltage error
• Module detected PROFIsafe CRC error
• Module detected PROFIsafe timeout error
• Reintegratable channel errors
Module parameters are set, and module has active diagnostics (at least one error is present)
Module parameters are not configured
Module parameters are configured, and module has no active diagnostics
Channel status/channel fault LEDs
The A and B LEDs indicate the current level of the associated input signals. At low counting
speeds the A and B LEDs show the actual state of the signals. At higher counting speeds, the
A and B LEDs will change at a limited rate to show activity. A and B LEDs flash when setting
the profisafe address.
