SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
TimeSy Reception of time synchronization messages via PROFIBUS (ref. to chap. 4.4).
The received value in seconds since 01-01-1900, 00:00 hours is displayed in hexa-
decimal representation, e.g.:
TimeSy: C355F7A6hex
This value has to be unequal 00000000hex and has to be changed about every minute
if time synchronization messages are received via PROFIBUS.
If the reception of time synchronization messages is deactivated in DIGSI with the
parameter GlobalSection.DP_TimeSyncEnable (ref. to chap. 2.1.1) then this is
indicated with:
TimeSy: OFF
In case of a communication break the seconds value received last is shown further-
more for one minute.
If no time synchronization message was received for a time interval of more than one
minute then it is shown in the display with:
TimeSy: Diff. >1min
With PROFIBUS-DP firmware V04.01.01 or higher also local time correction values
can be evaluated.
These correction values are contained e.g. in time synchronization messages of
SIMATIC PLC S7 CPU 412-2DP...CPU 416-2DP, CPU 414-3DP, CPU 416-3DP (from
firmware version 3.0 respectively) or of the Communication Processor Module CP
443-5 Extended (from firmware version 6.0).
The parameter GlobalSection.DP_TimeSyncEnable has to be set to the values
described in chap. 4.4.2 for this.
If the PROFIBUS-DP slave of the SIPROTEC device receives time synchronization
messages with a local time correction value then this is signaled with the additional
display of these correction value, e.g.:
TimeSy: C355F7A6+04
The first value (in hexadecimal representation) shows the seconds since 01-01-1900,
00:00 hours, the second value (in decimal representation) shows the signed correction
value in number of
1
/
2
hours.
In the example given above the correction value is plus two hours.
1.2.2 Block 2: Firmware versions and mapping file
Block 2 of the module-specific information shows the PROFIBUS-DP firmware version
as well as the number and version of the selected mapping file.
DP_SW PROFIBUS-DP firmware version loaded on the communication module.
Note:
If no PROFIBUS-DP mapping file was selected during parameterization in DIGSI then
all entries of Block 2 are marked with the text ’not loaded’:
MapNo.: not loaded
MapRev: not loaded
