4.4.2 Parameterization in DIGSI
Processing of time
synchronization
messages
The evaluation of time synchronization messages in the PROFIBUS-DP slaves of the
SIPROTEC devices has to be enabled with the parameter GlobalSec-
tion.DP_TimeSyncEnable during the definition of bus specific parameters after
selection of a bus mapping file (ref. to Figure 4-4)
Up to PROFIBUS-DP firmware V03.03.03 (for PROFIBUS modules up to HW
revision 3) and V04.00.06 (for PROFIBUS modules from HW revision 4):
From PROFIBUS-DP firmware V03.04.01 (for PROFIBUS modules up to HW
revision 3) and V04.01.01 (for PROFIBUS modules from HW revision 4):
Additional from PROFIBUS-DP firmware V03.05.01 (for PROFIBUS modules up to
HW revision 3) and V04.02.02 (for PROFIBUS modules from HW revision 4):
Value of
DP_TimeSyncEnable
Meaning
0 PROFIBUS time synchronization messages are not evaluated.
1 PROFIBUS time synchronization messages are evaluated.
Always the base time in the time synchronization message is
used for time synchronization.
Value of
DP_TimeSyncEnable
Meaning
0 PROFIBUS time synchronization messages are not evaluated.
1 PROFIBUS time synchronization messages are evaluated.
A
PROFIBUS-DP master S7 CPU -2DP/-3DP (from V3.00):
If the time synchronization messages contain a local time correc-
tion value (ref. to page 19, description to “TimeSy”) then the
base time plus the local time correction value is used for time syn-
chronization.
2 Always the base time in the time synchronization message is
used for time synchronization.
3 PROFIBUS time synchronization messages are evaluated.
A
PROFIBUS-DP master CP 443-5 Extended (from V6.00):
If the time synchronization messages contain a local time correc-
tion value (ref. to page 19, description to “TimeSy”) then the
base time plus the local time correction value is used for time syn-
chronization.
Note:
Please note, that depending on the used PROFIBUS-DP master unit (either SIMATIC
S7 CPU -2DP/-3DP or CP 443-5 Extended) different settings for GlobalSec-
tion.DP_TimeSyncEnable are necessary in the SIPROTEC device for correct
evaluation of the the local time correction value (see above).
