Glossary

Accessible devices
Accessible devices are all devices connected to an interface of the programming device / PC
that are turned on.
Automatic speed control, for example S120
Automatic speed control covers all elements and components for current and speed control
of an electric drive.
Automation system
Programmable logic controller for the open-loop and closed-loop control of process chains in
the process engineering industry and in manufacturing technology. The automation system
consists of different components and integrated system functions according to the
automation task.
Basic positioner (EPos)
SINAMICS converter function for calculating profiles for the position controller.
Baud rate
Baud rate is the symbol or modulation rate in data transmission. For example, if a symbol
comprises 4 bits, 9600 bps are transmitted at a modulation rate of 2400 baud. For symbols
with only two possible states (binary symbols), the baud rate is the same as the bit rate.
Bit memory
Bit memory is a component of the system memory of the CPU for saving intermediate results.
It can be accessed in bit, byte, word or double word mode.
Booksize device
Booksize design of the components of a drive unit, suitable for installation side-by-side.
Usually intended for the operation of multiple motors.
Bus
Joint transmission path to which all devices in a fieldbus system are connected; has two
defined ends.
