Page 106: Glossary
04/01 AWB2528-1401GB Glossary This glossary refers to subjects relating to PROFIBUS-DP. Acknowledge Acknowledge signal of the receiver for the signal received. Active metal component Conductor or conductive component that is live when in operation. Address Identification number of a memory location, a system or module within a network.
Page 107 04/01 AWB2528-1401GB Glossary Bus line Smallest unit connected to a bus consisting of a PLC, a coupling element for modules on the bus and a module. Bus system The entirety of all units that communicate with each other via a bus. Bus terminating resistor Resistor at the beginning and end of a bus line for preventing disturbance caused by signal reflections and...
Page 108 04/01 AWB2528-1401GB Glossary Field bus Data network on the sensor/actuator level. A field bus connects the devices of the field level. A field bus is charac- terized by high transmission security and real-time response. Field supply Voltage supply to field devices as well as signal voltage. Frame Entirety of all interconnected inactive equipment parts that do not have any contact voltage in the event of a fault.
Page 109 04/01 AWB2528-1401GB Glossary Inductive coupling Inductive (magnetic) coupling occurs between two current carrying conductors. The magnetism produced by the currents induces an interference voltage. Typical interfer- ence sources include transformers, motors, parallel cables and HF signal cables. Isolated Galvanic isolation of the reference potentials of control and load current circuits of I/O modules.
Page 110 04/01 AWB2528-1401GB Glossary Parameter assignment Assignment of parameters in the configuration software of the DP master for the individual stations on the bus and their modules. Abbreviation for programmable logic controller. Potential equalisation Matching of the electrical levels of the bodies of electrical equipment and the bodies of external conductive bodies by means of an electrical connection.
Page 111 04/01 AWB2528-1401GB Glossary Reference ground Ground potential in the area of grounding equipment. Unlike "ground", which always has zero potential, it may have any potential except zero. Reference potential Potential from which the voltages of all connected circuits are considered and/or measured. Repeater Booster for signals transferred via the bus.
