SIPROTEC PROFIBUS DP - Bus mapping 6MD662/3/4
C53000-L1840-B011-03
1.3.1.2
Bus specific parameters
The chap. “Bus specific parameters” in the manual “SIPROTEC Communication mod-
ule, PROFIBUS DP - Communication profile” describes the common settings for the
serial PROFIBUS DP communication.
In addition to this, further parameters are available if 6MD663/4 standard mapping
3-3 or 3-4 is selected.
PNO identification
number
GlobalSection.DP_IdentNo
Here, the PNO identification number of the redundant PROFIBUS DP slave of the
SIPROTEC devices has to be entered: 0x8138.
This must correspond to the GSD file which is used for parameterization in the PROFI-
BUS DP master (ref. to chap. 1.3.3).
Float to integer
conversion for
measured values
GlobalSection.DP_CountersWithStatus
Beside the activation of the status bits for counters (ref. to “SIPROTEC Communica-
tion module, PROFIBUS DP - Communication profile”, chap. “Metered measurands”),
this parameter also determines how the measured values are converted from the
SIPROTEC internal float format to the integer format used for PROFIBUS DP.
The following table shows the valid values for this parameter.
Please ref. to the manual “SIPROTEC Communication module, PROFIBUS DP -
Communication profile”, chap. “Scaling of measured values”, for general information
about the conversion and scaling of measured values.
Table 1-2
Parameter
DP_CountersWithStatus
The default value is 1.
Toggle bit timer
reload value
GlobalSection.DP_Ttoggle
Reload value (in 100 ms) for the supervision timer of the Toggle bit mechanism (ref.
to chap. 1.4.1.4).
The value 0 disables the Toggle bit mechanism.
If the reload value for the Toggle bit timer is less than the reload value for the PROFI-
BUS DP response monitoring timer
1
then the reload value of the Toggle bit timer is set
equal to the reload value of the response monitoring timer in the module firmware.
The default value is 30 which corresponds to 3 seconds.
DP_Counters
WithStatus
Status bit for counters
Float to integer conversion after
multiplication with scaling factor
0
no
without rounding of the measured value
1
yes
without rounding of the measured value
16
no
with rounding of the measured value
17
yes
with rounding of the measured value
1. Response monitoring: PROFIBUS DP standard mechanism for communication supervi-
sion. The reload value for the response monitoring timer in the slave is calculated by the
PROFIBUS DP master with the network size, the baud rate etc. This reload value then
is sent as part of the Set_Prm telegram to the slave.
