Issue Number: 3
The PROFIBUS-DP network activity can be monitored in the SI-PROFIBUS operating
status parameter, Pr S.01.006. When the SI-PROFIBUS is in data exchange with the
PROFIBUS-DP master controller, Pr S.01.007 will give an indication of the number of
cyclic data messages that are being processed per second. All possible values of
S.01.006 are given in Table 6.4.
Table 6.4 SI-PROFIBUS network diagnostics (S.01.006)
If the telegram selection (Pr S.01.008) = Auto (0), the number of input and output cyclic
words and the input and output mappings are set by the PLC master on the network.
The mapping configuration parameters can still be changed on the keypad but when the
module or PLC is reset or power-cycled, the PLC will set them up as originally
configured.
If the telegram selection (Pr S.01.008) = Custom (1), the number of input and output
cyclic words and the input and output mappings are set by the user.
If the telegram selection (Pr S.01.008) = STD Tel 1 (2), the number of input and output
cyclic words and the input and output mappings are set by the PROFIdrive parameters.
The mapping configuration parameters can still be changed on the keypad but when the
module is reset or power-cycled, the module will set them according to the selected
telegram (Pr S.01.008).
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).
