Motion Control
Siemens AG product family for drives that control motion. Covers all functions and
components for coordination in terms of position and time for machine components in
processing machinery.
Motor Module
Converter component (inverter) that provides power for one or two connected motors.
Non-isolated modules
In the case of non-isolated input and output modules, the reference potentials of the control
and load circuits are electrically connected.
NTP
The Network Time Protocol (NTP) is a standard for synchronizing clocks in automation
systems via Industrial Ethernet. NTP uses the UDP connectionless network protocol.
Onboard I/O
The digital onboard I/O of the SIMATIC Drive Controller is designed for connecting sensors
and actuators. Connection is over the interfaces X122, X132 and X142.
The digital inputs and digital outputs at interfaces X122 and X132 are mainly assigned to
SINAMICS Integrated. Through configuration (frames 39x), you can, however, also use the
digital inputs and digital inputs/outputs (X122/X132) for the CPU. The digital input/outputs at
interface X142 are assigned to the CPU of the SIMATIC Drive Controller and that
assignment is fixed.
Operating mode
The operating mode is a defined manner in which a device or system is able to execute its
function (for example continuous duty, short-time duty or periodic duty).
Operating states
Operating states describe the behavior of a single CPU at a specific time.
Organization block
Organization blocks (OBs) form the interface between the operating system of the CPU and
the user program. The organization blocks determine the order in which the user program is
executed.
