It is necessary to buy a hardware - learning PLC

we want to understand a problem, is to learn what is the nature of PLC? PLC controller and is called the programmable controller, what? Is to control the machine movement, make the machine according to the predefined program is running. This is like learning to drive, the human brain to PLC, to control the car according to the request of people to people want to go to the place.

in other words, learning PLC is skills training, is must use the material object to operate. Just like learning to drive, if you don't touch the steering wheel could learn to drive? Of course not!

there will be someone retort that wasn't there a simulation software?

can learn! Have the idea of people, like to play racing games to get a driver's license as naive!

to sum up, if you want to entry and learn PLC controller as soon as possible, or buy one.

how about the price? What to buy what type of PLC? Or no models each buy a?

this is involved in another question? We are going to study the function of PLC.

like I want to learn PLC logic control function.

wants to learn how to position function of PLC, want to learn the PLC analog functions, want to learn the communication function of PLC. Can buy the corresponding models of PLC products to learn. If I want to learn these functions, and don't want to buy so many, have a way?

the answer is: yes. You can buy the latest small points at least the kind of models. Will all these functions concurrently. Such as mitsubishi FX5U - 32MT- ES。

what programming software? Beginners will have such a question? PLC programming software is not a common software, but by the manufacturer's own development is part of the PLC products. So different brands of PLC controller have different matching the programming software.

such as mitsubishi with GX - the programming software Works2 and GX - works3。 Siemens STEP7 - MicroWin, etc.

use what brand of product will be installed the corresponding software programming and debugging.

to learn PLC electrician must have certain basis, because want to be programmed, must want to know the PLC control the execution of the original, the actual is to replace some of the traditional control circuit with PLC, but actuators is constant, with the contactor control motor for instance electricity.

multi-purpose programming software, simulation software, Siemens and mitsubishi are simulation software, can download to upgrade, can make up some programs in the simulation software, run the debug.
