System and Systems Approach
Every distinct activity in nature, technology, and society (photosynthesis, every evolutionary process)
What is a process?
A quantity at the end of a certain process
What is an output quantity?
Any piece of data that travels from the sender to the receiver.
What is information?
LOGO! Soft Comfort
Which program do we use to code PLC logic?
It is used to turn the output on
What is TON used for?
The space in which that process takes place
What is a process space?
A quantity that enters a process space and can change over time
What is an input quantity?
It is used to transmit information
What is a signal?
A binary coded decimal system in which the binary value is obtained by adding 3 to the decimal number before encoding
What is Excess-3 code?
It is used to turn the output off
What is TOFF used for?
A natural, social, or technical structure which operates independently in a given environment and has a defined purpose
What is a system?
They can be informational or process-related, and controllable or uncontrollable
What types of input information can exist?
Assigning a numerical value to a measured quantity
What is measurement?
A binary code in which two consecutive values differ by only one bit
What is Gray code?
It is used to store a given state
What is an SR bistable used for?
A set of elements that are in such a mutual relationship that separated subsystems do not exist
What is a structure?
In a system such as a refrigerator, for example, it is the temperature inside the chamber
What is a performance indicator?
A device that converts physical quantities into a measuring signal
What is a measuring transducer?
A signal that is coordinated in time with another signal or a clock
What is a synchronous signal?
It is used to connect/control a motor
What is an H-bridge used for?
A lack or excess of energy or matter
What can disturb a process?
In a system such as a refrigerator, for example, it is a button used to adjust the temperature
What is a control element?
It is transmitted using a transmission channel (wire, sound, wireless)
How is a measuring signal transmitted?
A signal that is not synchronized with a clock and can change at any moment
What is an asynchronous signal?
It is used for a very small voltage change in order to change state
What is EDGE used for?
