English [Auto] Hello guys and them in this lecture hall where we're going to learn what is the difference between a b and c and a soft B and C in more detail. So let's get started. Appeal's see it's actually programmable logic controller and we use it in order to control different equipment inside our automation panel. So what kind of equipment are we talking about. Contactors that activates Motors fever's Motors or want based motors we have relays that activate or act as a buffer in order to activate valves Orsillo no lights or to all of this equipment. We can use it in order to control the B-F DS in order to control anything that actuator real signals that will activate real machines and we can use it in order to control feedback signals from sensors like pressure like temperature open or closed circuit limit like limit switches. There is a large set of sensor that we can read using appeals. So their main thing about that DLC that it has its own input output pins we have usually the inputs and here let's say we have the outputs outputs are used to actuate whatever contactors our stuff we're using. Inputs are used in order to receive signals from sensors and they are equipped and embedded and this be. Also we can if the number also appeals the advantages. If the number of iOS is limited you can extend that using embedded audio modules like these two modules zeer we are extending the number of digital and analog inputs and outputs. Because let's say we have already here 20 and you are requiring 40. So we can just equip. So we can just equip it with these. I almost do. Why do we do we need DLC in the first place. All the classical control design uses stuff like relays stuff like contactors to build the control circuits and that consumes a lot of equipment and a lot of devices that a lot of wiring and complicated circuits. We can just replace all of that was a program we are in there be also in order to do these complicated algorithms with software rather than with wiring relies on hardware in order to get to the desired I'll go with him. So it's like either you build your algorithms with the hardware on the wiring bitches complicated if the algorithm is complicated or just write the software that you can modify easily test easily using eppi else. Also appeal's see something like communication protocols like Modbus DCP or RTU Ethernet IP coffee bars Roughie net. There's a lot of protocols that are used in order to control multiple devices using only two wires or one cable. So let's say we have this ethernet port we can extend it to a switch and control let's say 10 or 20 speed controllers or via these with just one wire connected to that switch. I mean that's really saves you a lot of wiring a lot of programming. It's really wonderful. Now this soft DLC is actually a software that is installed on your computer so your computer doesn't really have I O that doesn't have input outputs you cannot really read sensors easily. It just uses a bus like Ethernet in order to communicate with something outside the scope of the software. It's just use protocol in order to communicate with the stuff from the outside world. It has all the functionalities of a real PLCC but the only drawback is it can not really actuates signals directly. So it's really useful if you will have a bus system so you can just take an ethernet cable from your computer and also control multiple via these or whatever devices that support beracha called Control and here in our situation we're going to use the or do we know in as an iPod car which will activate whatever we have in the outside world equipment. So in our case we're going to use and we know that is going to act as an eye or all to like to a different device and equipment in our electrical automation. So this is the main difference between a soft TLC and up TLC and we can't summarize it as well as softly else out mock up the abilities it can support maybe more programming languages. I mean the answers can also support multiple programming languages but that requires some sophisticated do on in order let's say to program in the C and structure decks. FBD usually the standard DLC is come with Lader design on it with later a programming language only but soft B C's like ghauts is here that we are going to use supports up to five programming languages and that's a real advantage. But the drill back as I said no I know is directly coming out of your lap. So this is the main difference guys and we're going to continue the next lecture to explain about more stuff to the next lecture.
