Diagnostics
The diagnostic concept for the bus coupler consists of two components. Firstly, diagnostic
data is supplied to the control system via PROFIBUS in the form of diagnostic bytes.
Secondly, local diagnostics are available, whereby the error type is indicated by the specific
flashing codes of the LEDs on the bus coupler.

Activating/deactivating the diagnostic formats
The diagnostic format can be set as a parameter on the terminal. You can select either
"IL PB BK DI8 DO4 Format", "Status-PDU Diagnostics" or "ID-Specific Diagnostics". By
default, "IL PB BK DI8 DO4 Format" is activated. The"Status-PDU Diagnostics" format must
be set for diagnostics of PROFIsafe I/O modules.
