PLC's
What does PLC stand for?
Programmable Logic Controller
What does HMI stand for?
Human Machine Interface
What is a network
What is the purpose of a timer?
To count time and have loads turn on or off based on timer states
George Westinghouse, and Nikola Tesla
What is a Programmable Logic Controller
A computer engineered to handle industrial tasks with precision and reliability
What is the name of the program we use to create or modify HMI programs?
Studio5000 View Designer
Public vs Private network
Private can is password protected, public is not
What two bits are solely numerical/informative?
ACC, PRE
What acts would Thomas Edison and his lab assistants perform publicly in an attempt to vilify AC?
The electrocution of animals
Define a tag
A tag is a name you give to an input or output, instead of the raw data point. Stop button is much easier to remember than Local:1:I:Pt00.data
What is it called when we simulate the HMI screen on our computer as opposed to actually downloading to the HMI screen?
Emulation, to emulate.
What is stuxnet?

What type of tag is a timer?
A base tag
What is magnetic flux?
What is the instruction used to ensure a rung is executed once, and only once?
ONS (One-shot)
If color table is used to change colors when a actuator/load is on/off, what is the purpose of a state table?
To change the position, size, color or angle of an output. Where as color only changes color.
What category network cable do we have inside our panels?
Category 6
When does the DN bit on a TOF come true?
Any time the ACCumulate is anything other than the PREset
Why is AC used over DC to power society on a large scale?
AC is constantly in motion already, making it easier to transform either to a higher or lower voltage. It is more efficient.
Although used to some degree in industry, why do we refrain from using latch/unlatch bits?
When used without proper precautions, they have a tendency of turning/staying on when restarting a machine. Even though the inputs that control that load are not true.
Name the 3 tabs that modify the corresponding object on an HMI screen.
Properties, animations, events
What is the rate of data transfer that our networking cables transmit data?
1gbps up to 100M or 10gbps under 150 feet
what data type is a timer?
Timer, data type
Name the place on earth considered the most desolate location on the planet. It is closer to the international space station than any other land mass.
