Presentation Transcript

  1. Requirements for a fieldbus system • Open, multi-vendor system • Integration in common automation concepts • Low overall cost • Ease of familiarization and installation • Wide-ranging with any network structure • Minimal space requirement for bus electronics in the field devices

  2. Integration of Power Circuit Breakers

  3. Communication concept for low-voltage switchgear Control level PROFIBUS-DP Field level Actuator-sensor level Actuator-sensor interface

  4. Communication concept for low-voltage switchgear

  5. Communication concept for low-voltage switchgear

  6. PROFIBUS-DP features (1) • Open, multi-vendor system standardizedto DIN (E) 19245 Part 3 / EN 50170 • More than 1000 vendors offer more than 1500 PROFIBUS products • More then 3,000,000 PROFIBUS nodes already installed worldwide • User organizations in 23 countries support usersworldwide • Integration and interfacing to common automation concepts • World market leaders of PLCs have or plan PROFIBUS-DP master modules • Short reaction times • Up to 12 Mbaud data transfer rate

  7. PROFIBUS-DP features (2) • Extensive, customer-friendly functionality • Simple diagnostics tools permit service work even without a system specialist • Wide ranges • Up to 9.6 km using RS485 technology • Even more than 100 km with fiber optics • Line, radial and ring structures when using optical link modules (OLM) • Up to 126 bus stations (of which 122 field devices)

  8. SENTRON supports PROFIBUS DPV1 (1) • PROFIBUS DPV1 is extension of existing PROFIBUS functions, compliant to older devices • Very easy communication functions to devices supporting PRODIBUS-DPV1 with a configuration software (Switch ES Power) or SCADA system (WinCC) • Devices supporting DPV1 can talk to two PROFIBUS masters at the same time

  9. SENTRON supports PROFIBUS DPV1 (2) • Communication without DPV1: • Data to be transmitted with every cyclic telegram • Amount of data can not be changed in the operating mode • Low performance if amount of data is too big

  10. SENTRON supports PROFIBUS DPV1 (3) • Communication with DPV1: • Communication of datasets DS with the maximum size of 245 Bytes in just one additional telegram • DPV1 telegrams will only be transferred once triggered by a customers software, for example Switch ES Power • The cyclic transmission is running parallel
