11.2.3 SI-PROFIBUS network diagnostic
The operating status of the SI-PROFIBUS module can be viewed in the network
diagnostic parameter (Pr S.01.006). All possible values of this parameter are described
in Table 11.4.
Table 11.4 SI-PROFIBUS operating status
11.2.4 Mapping status
If the SI-PROFIBUS Network Diagnostic parameter (Pr S.01.006) indicates "First
Failure" or "Second Failure", a mapping configuration error has been detected. The
reason for the error is indicated by the SI-PROFIBUS input mapping status parameter
(Pr S.01.022) and the SI-PROFIBUS output mapping status parameter (Pr S.01.023).
When a mapping error has been corrected, reset the SI-PROFIBUS module by setting
MM.007 to On (1).
The input mapping error codes are described in Table 11.5 on page 63, and the output
mapping error codes are described in Table 11.6 on page 63.
Value Text Description
0 Network OK Network OK/healthy.
1 Intilaization
A part of the SI-PROFIBUS initialization sequence was not
successful. If this fault persists after a power-cycle, replace the
SI-PROFIBUS.
This error may also occur if the PROFIBUS-DP master is not
connected.
2 Initialized
The SI-PROFIBUS has initialized correctly and is waiting for the
Profibus-DP master to initialise communications.
This error may also occur if the PROFIBUS-DP master connection
is removed.
3 Network no data Network OK/healthy but no network cycles per second detected.
4 First Failure
Mapping configuration fail when mappings are set by input
mapping menu and output mapping menu (S.01.008 > 0) or ASCI
configuration fail when mappings are set by GSD files (S.01.008 =
0).
5 Second Failure
Mapping configuration fail when mappings are set by GSD files
(S.01.008 = 0) or ASCI configuration fail when mappings are set
by input mapping menu and output mapping menu (S.01.008 > 0).
6 Third Failure
SI-PROFIBUS does not support CTNC or PPO4 (S.01.030 = 1 or
2), and does not support ProfiDrive V2 (S.01.008 > 2).
