A Programable Logic Controller is simply a small computer used to control some system such as garden watering systems. They are everywhere. The computer in microwave ovens, television sets, fridges etc are all PLCs. Generally the term is used to describe a computer that doesn't normally interact with a human but just controls something like those things listed above. There are many many more PLCs around the place than computers that humans comminicate with.

∙ 11y ago1- For given internal complexity, a PAL can have larger N and M
2-Some PALs have outputs that can be complemented, adding POS
functions
3-No multilevel circuit implementations in ROM (without external
connections from output to input). PAL has outputs from OR terms as internal inputs to all AND terms, making implementation of multi-level circuits easier.

What are the major advantages of Emitter-coupled logic?
Ilv
What is snarled program logic called?
Snarled program logic is unstructured logic, also known as "spaghetti" logic. Compiled machine code is the ultimate example of snarled program logic. Although spaghetti code is more compact and efficient than structured code, it is extremely difficult to both comprehend and maintain. Hence we use structured programming languages to provide a high level of abstraction between the logic of the programmer and the snarled logic of the machine-dependant code.
What is the Difference between program and flowchart?
Flowchart it is diagrammatic Program it is coding. A flowchart is drawn out on paper, and shows the logic of an if/then/else statement. The programming actually is the if/then/else, not just the logic.
What is an English-like statement used to describe the logic of a program?
Pseudocode.
Need of program Logic controllers?
Program logic controllers are used to control the operation of most systems.
What are some advantages and disadvantages of using programmable logic to control machines versus monitoring and adjusting processes manually?
advantages- don't have to change the machine in order to adjust it, just change the program. disadvantage- your program could be wrong or screw up.
What is AOI logic and universal logic?
list three advantages of AOI logic
What did Key Telephone Systems come out of?
KTSs evolved from wired logic and electromechanical operation to stored program or firmware control
3 State four advantages of PLC control compared to hard-wired relay control systems and conventional computer control systems?
There are a number of advantages for using PLC(Programmable Logic Controller) control compared to other conventional types of control.Here are a few examples:With a large control scheme, a PLC takes up less room.You can change your control scheme (program) without having to physically change the wiring to a number of relays.A PLC is relatively much faster and allows for closer process tolerances.A PLC is more reliable as there are no moving parts.
What are the disadvantages of logic gates?
advantages for and gate
Advantages of programmable logic array-PLA?

What are the major advantages of Emitter-coupled logic?
Ilv
What is the advantages of domino logic?
less dynamic power
What is objective of control structure and explain different control structre in c plus plus?
1.to clarify the program logic. 2. to serve as a guide for the program coding. 3. helps to identify alternative methods. BY. Brian Mwamuye Mwananje From Mombasa Kenya
What is Advantage of logic analyzer with built in digital pattern generator over simulator?
logic analyzer advantages
What are the advantages of nand gate?
because it is an universal gate that control and repairs other gates.
