Description
The LEDs on the module indicate hardware
errors, bus errors, etc.
The operator unit:
– Shows current error messages in plain text
– Offers access to the diagnostic memory.
The 8 status bits display common diagnostic
messages (global error message).
Internal diagnostics data can be read via the I/O
diagnostics interface. In this way, detailed
diagnostic information can be accessed, even if

network-specific diagnostic functions.
The I/O diagnostic interface offers:

– Access to the diagnostic memory
– Read access to internal parameters and data.
