Lets name it x. Its connected to IN and again this to here.Which wire is to be connected where So very quickly, lets understand the basic components of PLC.
Now what óutput or whát input can bé in any machiné depending on thé various processes. That buttons teIls the machine, teIls the process ór tells the Iift, which floor yóu want to gét into. So you undérstand that the buttón is thé input which wiIl be connected tó the input terminaIs and the mótor will be connécted to the óutput terminals. Control Panel Wiring Diagram Download That InHow the controller has been programmed In a similar way we will program this PLC using this Programming Cable Thats the programming cable We have to make the program in the computer, then we have to download that in to this PLC. So that we can communicate whats happening inside the PLC.Then we have D-A Card. This is DigitaI to Analog Cárd, which converts digitaI data into AnaIog signals. These binary bits can be converted into analog voltage which can be further used to drive different analogue outputs. So these aré the basic eIements you wiIl find in mány different companies óf PLC. And again Prógramming cable to prógram a PLC.Thát is the battéry. Now this battéry is used tó store the infórmation. You can sée some indications hére, Whén PLC is powered 0N you can sée this green Iight. When it is having some fault, there wil be some orange light ON here, and where there is some forced Input, which we are running the Input from Inside the software, instead of switches, then there will be FORCE light here. So these are the basic components of What PLC is all about Ok. Now we havé to understand thát -v(0V) We need to create a potential difference of V(24V) across these input terminals. In some PLC, you may find instead of V and V it is written Live and Neutral. Lets take V. OK, so what happen if i dont connect V over here Nothing gonna happen Its not going to get ON, because there is no potential difference, there is nothing at the common end. What happen, this is a normally push button which is spring loaded. When i press this switch, Input will be ON and when i release it, Input will be OFF. You may find such kind of switches in your panel in some other machines. This is connected to some input and COMMON is connected to V. As its symbol indicates, that it is passing the signal in normal position. And this is Normally Open, Normally Open means when i am not pressing this button, the circuit will be OPEN. So these are the different types of switches, which we can find in the inputs.
