Actuator
Actuators can be power relays or contactors for switching on loads, or they can be loads
themselves (e.g., directly controlled solenoid valves).
Automation system
Programmable logic controller for the closed-loop and open-loop control of process chains in
the process engineering industry and manufacturing technology. The automation system
consists of different components and integrated system functions according to the
automation task.
Baud rate
Data transmission rate indicates the number of bits transmitted per second (baud rate = bit
rate).
Bus
A common transfer route to which all nodes of a field bus system are connected; it has two
defined ends.
Bus cable connector
Physical connection between the bus node and the bus cable.
Bus, self-assembling
The modules are lined up on the mounting rail, and are mechanically and electrically
connected to each other with a U connector as they are swiveled into position. In this way
the bus is extended with each module.
Configuration
Systematic arrangement of the individual modules (configuration).
Connection plug
Physical connection between device and cable.
