Glossary
Active RS 485 terminator
Separate -> terminating resistor in segments at transmission rates of 9.6 kbps to 12 Mbps.
The power supply is separate from the bus nodes.
Bus
Data transfer bus to which all nodes are connected. It has two defined ends.
In the case of PROFIBUS, the bus is a twisted-pair cable or optical fiber cable.
Bus connector
Physical connection between the node and bus cable.
Bus segment
-> Segment
The bus line between two terminating resistors forms a bus segment.
A bus segment may contain up to 32 bus nodes. Segments can be coupled, for example via
RS 485 repeater or diagnostic repeater.

Bus system
All nodes physically connected to a bus cable form a bus system.
Configuring
Configuring means entering a PROFIBUS configuration with all the specific parameters
using, for example, STEP 7 or COM PROFIBUS.
