9.2.5 Communication errors
This state is displayed by means of the Sercos-III-LED with flashing pattern # 13,
see Sercos-III-LED on page 84.
Communication errors refer to the Sercos communication profile (SCP) and report
either errors, warnings, procedure command - specific states or operational state
specific states.
The reports are very extensive. Thus, for the parameter IDN / S-0-0390
Diagnostic
number
, the individual reports have to be taken from the Sercos specification.
For example: status code = 0x4002 (diagnosis class = 0xF for errors) means that the
connection was interrupted, because the data losses was too high.
9.2.6 Identification
This state is displayed by means of the Sercos-III-LED with flashing pattern # 14,
see Sercos-III-LED on page 84.
The message is triggered in case of a request for identification and serves for the
location of the appropriate device or for validation of the Sercos address. After request
the Sercos-III-LED flashes four seconds and the device sends an

2. or via the S/IP identify service, Message-Type = 94
