Introduction and overview 1.2 Bus systems Integration into automation systems Integration and linking to current concepts in automation is similarly unproblematic since all the large manufacturers offer PROFIBUS DP master modules for programmable logic controllers (PLCs). And with high data transfer rates of up to 12 MBaud/s, the systems operate almost in real time.
Page 13
Introduction and overview 1.2 Bus systems The following figure shows communication on PROFIBUS: ● Token passing between the available masters ● Polling between master and slave nodes Figure 1-1 Communication on PROFIBUS The figure above shows an example with three master modules and seven slaves. The three master devices form a logical ring.
Introduction and overview 1.2 Bus systems Acyclic data transfer Acyclic data transfer is implemented via DPV1. DPV1 adds several functions to the existing PROFIBUS standard. These include reparameterization of the slave configuration during operation, and the establishment of acyclic data traffic. With the help of DPV1, data can also be read direct from the slave by a class 2 master, even though it still has a logical link to a class 1 master.
Ethernet. Data transfer There are several methods of transferring the data of the SENTRON circuit breakers on PROFIBUS DP to Ethernet. These are represented here by two solutions using SIEMENS components: Solution 1 A SIMATIC S7 controller is equipped with a PROFIBUS DP interface (CPU-internal interface or modules with communications processors) and an Ethernet interface.
Introduction and overview 1.2 Bus systems Message frames The message frames allow process data (input/output data) to be written or read either individually or in groups. Modbus RTU is used on different transmission media. Implementation on the RS485 physical bus, a shielded, twisted-pair cable with terminating resistors as on PROFIBUS DP, is widespread.

3WL air circuit breakers 3.3 Metering functions If increased harmonics are measured, it is advisable to carry out a 3-phase system analysis. This measurement, including the neutral conductor, must be carried out with the appropriate harmonics measuring devices over an extended period up to the 100th harmonic. The right choice of measuring connection point and professional analysis of the measured data are essential components in developing a concept that removes or at least reduces the harmonics and associated faults.

Zone Selective Interlocking 5.1.1 Introduction With circuit breakers on several grading levels, the aim is to assign these selectively to each other so that in the event of an overcurrent only the circuit breaker immediately upstream switches off the overcurrent. 5.1.2 Selectivity A plant with several protective devices switched in series is selective only if the protective...
Zone Selective Interlocking 5.1 ZSI 5.1.3 Time selectivity One method of achieving this aim in the short-circuit or ground fault is time selectivity of the circuit breakers. Figure 5-1 Example of time selectivity This means each level of the circuit breaker receives another time delay (t ) that rises in the direction of the incoming supply.
Zone Selective Interlocking 5.1 ZSI 5.1.4 ZSI function The ZSI function (ZSI = Zone Selective Interlocking) offers full selectivity with an extremely short delay time (t ) regardless of the number of grading levels and the location of the fault in the distribution system in the short-time-delayed S range and G range of the trip characteristic.
Zone Selective Interlocking 5.1 ZSI 5.1.5 Operating principle ● Every circuit breaker is equipped with a ZSI module ● The ZSI modules are linked to each other via twisted-pair connections ① ② ● The ZSI output (ZSI OUT) is connected with the ZSI input (ZSI IN) ●...

Zone Selective Interlocking 5.2 Examples 5.2.2.3 Example of 3 grading levels without coupling switch The graphic below shows the functional principle of the ZSI function using an example in the power distribution system. Both SENTRON VL and SENTRON WL circuit breakers are used in different grading levels.
Zone Selective Interlocking 5.2 Examples Short-circuit in grading level 2 ● Q1 and Q3 determine a short-circuit, Q4 does not. This is why Q3 also does not receive any ZSI information from Q4, but in turn provides ZSI information for Q1. On the basis of this information, Q3 knows that it is closest to the short-circuit and trips with a delay of t = 50 ms instead of t = 200 ms.
Zone Selective Interlocking 5.2 Examples 5.2.2.5 Coupling switch Wiring example of 3 grading levels with coupling switch The TIE BRKR function (X4-1, 2) ensures that the ZSI IN signal (3, 4) is immediately forwarded to the output ZSI OUT (5, 6) even if the coupling switch is switched off. Without the TIE BRKR function, the ZSI signal would not be forwarded.
Zone Selective Interlocking 5.2 Examples 5.2.2.6 Wiring example The example shows ZSI wiring and the set delay times in a mixed system with 3WL and 3VL. Grading level 2 is a coupling switch. Coupling switches are treated as separate grading levels and receive their own delay time.

Zone Selective Interlocking 5.2 Examples 5.2.2.7 Circuit breakers without ZSI function Circuit breakers without ZSI function can be integrated into a system equipped with ZSI. However, they must have no delay time since otherwise the selectivity of the circuit breakers cannot be guaranteed.
Zone Selective Interlocking 5.3 SENTRON 3WL SENTRON 3WL To be able to use the ZSI function on the SENTRON WL circuit breaker, the external CubicleBUS ZSI module must be used.

Zone Selective Interlocking 5.3 SENTRON 3WL 5.3.2 Applications The function of ZSI can be used for the short-circuit between the phases (S), short-circuit to ground (G), or both simultaneously (S + G). The ZSI module provides ZSI information for the medium voltage level via the MV-OUT signal.
Zone Selective Interlocking 5.4 SENTRON 3VL SENTRON 3VL 5.4.1 COM20/COM 21 To be able to use the ZSI function on the SENTRON VL circuit breaker, the external communication module COM20 (PROFIBUS DP) or COM21 (Modbus RTU) and an ETU or LCD ETU with communication capability must be used.

PROFIBUS data transfer Integration of the circuit breakers into a communication system There are diverse possibilities for integrating the SENTRON circuit breakers into a communication system. A shared profile (type and content of the data transfer) for SENTRON WL and SENTRON VL also enables the use of identical programs at the automation level and the PC level.
PROFIBUS data transfer 6.3 Communication with a PROFIBUS DP class 1 master without COM20 Figure 6-1 Communication options of PROFIBUS DP with SENTRON WL and SENTRON VL Profile basis The standardized profile for circuit breakers (PI profile PI 3.122) kept by PI (PROFIBUS International) is used as the basis for the profile.
The current version of the GSD file for the SENTRON circuit breakers can be downloaded from the Service and Support Homepage: 1. Navigate to Service and support (http://support.automation.siemens.com) 2. Enter "sentron gsd" in the area "Search for product information" and select "GO"...

Note The settings on the "Hex Parameterization" tab do not need to be considered here. The PROFIBUS DP addresses 0 and 126 cannot be assigned.
PROFIBUS data transfer 6.6 The three communication paths Reading out the diagnostics address for S7 functions For certain functions (e.g. reading out diagnostics), the diagnostics address is subsequently necessary. You obtain this using the context menu (right-click on the slave) and the function "Object properties".

PROFIBUS data transfer 6.6 The three communication paths Path 1 enables fast and simple entry to PROFIBUS DP communication. This path contains sufficient data to meet most requirements. Communication with path 1 always takes place with a class 1 master. With cyclic data, certain contents are predefined. These can be changed in the three basic types and thus easily adapted to requirements (e.g.

PROFIBUS data transfer 6.9 Cyclic data traffic Basic types for cyclic data exchange Due to the large volume of data provided by the SENTRON circuit breakers, it was necessary to find a compromise between data volume and performance on PROFIBUS DP. If a large volume of information is transferred with each data exchange but little of it is used, this impairs the performance capability on PROFIBUS DP.
