    Product Overview Y link The Y link consists of two IM 157 interface modules and a Y coupler that are interconnected via bus modules. The Y link provides a gateway from the redundant DP master system of an S7-400H to a non-redundant DP master system. This permits devices with only one PROFIBUS-DP interface to be connected to an S7-400H as a switched I/O system.
  • Page 17 Product Overview What is PROFIBUS-PA? PROFIBUS-PA is the communication-compatible enhancement of PROFIBUS-DP with transmission technology suitable for applications in potentially explosive areas. The transmission system of PROFIBUS-PA meets the international standard IEC 61784-1:2002 Ed1 CP 3/2. With the PROFIBUS-PA bus system, the measuring transducer and actuators in the potentially explosive area can communicate over long distances with the programmable logic controller.

  • Page 171 Glossary Address The address of a node is used to localize it in the network. It must be unique throughout the entire system. Aggregate current Aggregate current of all the PA field devices. Automation system An automation system is a programmable logic controller that consists of at least one CPU, various input and output modules and human-machine interfaces.
  • Page 172 Glossary Diagnostic interrupt Diagnostics-capable modules use diagnostic interrupts to report system errors that they have detected to the central CPU. In SIMATIC S7/M7: When an error is detected or disappears (e. g. wire break), the module triggers a diagnostic interrupt, provided the interrupt is enabled. The CPU interrupts the processing of the user program and lower priority classes, and processes the diagnostic interrupt block (OB 82).

  • Page 174 Glossary Ground Ground refers to the entirety of all interconnected inactive parts of an equipment that cannot possess a dangerous contact voltage, even in the event of a malfunction. Ground The conductive mass of earth, the electrical potential of which can be set to zero at any point.
  • Page 175 Glossary Master Masters may, if they possess a token, send data to other nodes and request data from other nodes (= active node). DP master are e. g. the CPU 315-2 DP or the IM 308-C. Parameter assignment Parameter assignment is the handing over of slave parameters from the master to the slave.
  • Page 176 Glossary PROFIBUS-PA PA stands for process automation and extends the scope of the PROFIBUS-DP family to include process engineering. Process engineering includes both intrinsically safe applications in the chemical engineering industry as well as non-intrinsically safe applications such as power plant automation, food processing and sewage treatment.
  • Page 177 Glossary TN-S system In a TN-S system, the neutral conductor (N) and protective conductor (PE) are routed separately from each other. The neutral conductor is connected to the grounded protective conductor at a central point, and only there. The conductor can be grounded any number of times.
