Page 9: Bus Specific Parameters
Bus specific parameters Bus specific parameters The following settings for the serial communication between the PROFIBUS-DP master and the PROFIBUS-DP slave of the SIPROTEC device have to be defined when programming the device. The PROFIBUS-DP slave address of the SIPROTEC device is set using Slave address the parameterization system DIGSI. - Page 10 Bus specific parameters Configuration data The DDB file characterises the SIPROTEC communication module as a “slave with modular design“, i.e. depending on the selected mapping, the number of input and output data is modified without changing the DDB file. The configuration data to the various devices are contained in the corresponding bus mapping documents (ref.

Page 13: Behaviour Under Special Operating Conditions
Execution of switching operations via PROFIBUS-DP Behaviour under special operating conditions • A change of the switching device status which was not initiated by the PROFIBUS-DP master (e.g. circuit breaker trip) is recognized by the PROFIBUS-DP master by a change of the value of the switching device status in the corresponding bit positions of the input message. - Page 14 Execution of switching operations via PROFIBUS-DP 7SJ61/62/63, 6MD63, 7UM61 PROFIBUS-DP – Communication profile C53000-L1840-B001-02...

Page 17: Annunciations To The Profibus-Dp Master
Annunciations to the PROFIBUS-DP master Annunciations to the PROFIBUS-DP master Note When analysing the annunciations of the SIPROTEC device in the PROFIBUS-DP master, it should be noted that due to the cycle period of the PROFIBUS-DP system or due to the cyclic processing time of a PLC, temporary changes of an annunciation’s value (ON and OFF within one cycle) may eventually not be recognized. - Page 18 Annunciations to the PROFIBUS-DP master 7SJ61/62/63, 6MD63, 7UM61 PROFIBUS-DP – Communication profile C53000-L1840-B001-02...

Page 23: Profibus-Dp - Parameterization In Digsi
PROFIBUS-DP – Parameterization in DIGSI PROFIBUS-DP – Parameterization in DIGSI Mapping files The parameterization of PROFIBUS-DP for a SIPROTEC device requires the selection of a mapping file which fixes the allocation of the data objects of the SIPROTEC device to the positions in the PROFIBUS- DP messages. - Page 24 PROFIBUS-DP – Parameterization in DIGSI Note The size of the PROFIBUS-DP messages (number of commands, annunciations, measured values, metered measurands) in output or input direction is exclusively fixed by the selection of a standard mapping. The standard mappings 1 to standard mapping m (m = device type dependent number of standard mappings) enclosed to DIGSI 4.1 are offered for selection furthermore but shouldn't be used for new device parameterizations.

PROFIBUS-DP – Parameterization in DIGSI Customization of the allocations The identification whether an information is routed on system interface (PROFIBUS-DP) is shown in the columns "Source system interface" and "Destination system interface" in the DISGI Configuration matrix. A cross ('X') in this column indicates the associated information as "routed on system interface". -

A control of these objects via PROFIBUS-DP as a substitute for using binary inputs is however often meaningful.

Page 29: Scaling Of Measured Values
PROFIBUS-DP – Parameterization in DIGSI Scaling of measured values Measured values will be transferred via PROFIBUS-DP between the SIPROTEC device and the PROFIBUS-DP master as integer values (two bytes, ref. to chap. 5.4) but they are in general available in the SIPROTEC device in floating-point format as a percentage referred to the parameterized nominal values of the primary equipment. -
