7. PROFIBUS communication with SENTRON WL and SENTRON VL PROFIBUS Profile for SENTRON Circuit Breakers The PROFIBUS User Organization promotes the use of joint multi vendor profiles for different device classes such as motor starters and measuring instruments For low voltage switchgear and controlgear a separate profile has been defined for circuit breakers This forms the basis for the common PROFIBUS profile for the SENTRON VL and SENTRON WL circuit breakers The PROFIBUS User Organization profile has been extended to include diagnostic functions and DPV1 enhancements Cyclic Data Transmission With cyclic data transmission a defined quantity of user data is transmitted with each message When the slave in this case the SENTRON WL or SENTRON VL is parameterised the quantity of data to be transmitted cyclically between the circuit breaker and PLC must be defined Cyclic data transmission is the best method of transferring information that is needed quickly and on a continuous basis The interval between two values depends on the number of stations involved the quantity of data and the baud rate The quantity of data cannot be changed during operation For this reason data transmission that is exclusively cyclic is Suitable for communication that generally handles small volumes of user data Cyclic data transmission however is not suitable when larger data packages are to be transmitted for example for occa

OFIBUS DP must have a unique address which means that a new address must be assigned when the PROFIBUS DP modules are commissioned The COM10 module of the SENTRON VL adopts the new address The old address however remains valid until the connection with a class 1 master Is interrupted If no cyclic data exchange is taking place with a class 1 master the new address becomes effective immediately With Switch ES Power the process Is as follows While the parameters are being downloaded with a new address the address is copied and activated and as a result the connection with Switch ES Power is interrupted immediately As of this point the slave can be accessed at the new address and Switch ES Power must be restarted The COM15 module of the SENTRON WL adopts the new address although it cannot be used until the 24 V DC supply voltage for the CubicleBUS has been interrupted briefly The address is not active until the voltage is restored Changing the address with Switch ES Power To change the PROFIBUS DP address using Switch ES Power you first have to ensure that the current address e g 126 at initial commissioning has only been assigned once For this reason all of the new COM10 COM15 modules must never be connected to the PROFIBUS DP at the same time otherwise all modules with the same address would adopt the new one It Is therefore important to ensure that the new modules are connected to the PROFIBUS DP on
