find the advantages of programmable logic device over TTL(transistor transistor logic)

Expert Solution

Few advantages of PLDs over IC's::

Reduction in board space requirement.
Reduction in power requirement.
Design security.
Compact circuitry.
Higher switching speed.
Flexibility.

You don't have to be compelled to amendment your whole device to update your computer code.

You can modify the behavior later as you wish it.

One massive advantage for makers is that, if there are 2 or 3 variants of the device, they do not have to be compelled to style 3 totally different ICs. they'll simply produce a programmable IC, and modify it’s behavior programmatically. which may be a ton cheaper and easier.

Some comman advantages of PLC ar as follows:

Easy to install and troubleshooting: In arduous wired relay primarily based systems, installation time is a lot of as compared to the PLC primarily based management panels.
Availability of Large contacts: PLC programming tools contain an internal sizable amount of contacts that may be used for any amendment evoked in several applications.
Cost effective: Advanced technology and enormous production of PLC makes it cheaper than the opposite controller or relay primarily based systems.
Simulation feature: PLC programming code comes with the simulation options by default.
Simple programming methods: PLC is given straightforward programming methods to program the PLC like Ladder or Boolean sort of programming.
Ease of maintenance: As compared with the management systems like relay primarily or micro-controller based systems, the maintenance value of PLC is low.
Documentation: The technologist will program and print simply the programs of PLC for future use.
