Actuators are, for example, power relays or contactors for switching on load devices or load
devices themselves (e.g. directly controlled solenoid valves).
Programmable logic controller for closed-loop and open-loop control of process chains in
industrial processes and manufacturing technology. The automation system consists of
different components and integrated system functions according to the automation task.
Data transmission rate indicates the number of bits transmitted per second (baud rate = bit
rate).
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.
Joint transmission path to which all nodes of a fieldbus system are connected; has two
defined ends.
In SIMATIC S7, a code block is a block that contains a section of the STEP 7 user program.
(in contrast to a data block, which contains only data)
Assignment of modules to slots and addresses.
Physical connection between device and cable.
Data whose content belongs together and must not be separated is known as consistent
