Hello. 1
In this video we are going to learn what is PLC and what is the delta PLC. 2
DVP models PLC as basically programmable logic controllers are programmable control devices that 3
process the information from the inputs in the program written in the CPU and operate the devices connected 4
to their outputs as desired. 5
So we have a PLC we have are IOs and also we have outputs so inputs according to our inputs. 6
CPU This is our CPU ,so CPU is processing information inside of it and it is giving and outputs 7
and connected output devices is desired according to programmer according to who designed the PLC 8
programs and etc. so we can say it with the fast developing technology PLCs are logic controller 9
devices that it is used in the wider control area. 10
Integrated with analog control position control and different communication systems so different communication 11
systems means we can use modbus, profinet, profibus ,ethercat, canopen an Internet IP Communications 12
as basically and these are really popular and the common communication mode communication techniques 13
in the industrial area but for delta PLCs modbus is the very very common and for example for 14
the delta plcs if you need to use a profibus communication you need to add extra special modules but 15
the important thing of this video you must learn also we need to understand this. 16
CPU or plcs are reacting according to inputs and assigning or changing to outputs according to 17
inputs.ınputs is really important for the CPU and 18
According to this inputs and according to our programs CPU is changes its own outputs so plcs are 19
working like this DVP series PLC models is that DVP SS2 so SS means slim and standard SA2 - SA 20
slim and advanced SA means slim and Internet communication and sx2 slim analog and sv2 21
to slim high performance so the names are coming slim standard advanced for Internet and analog and 22
performance but in here we can just immediately check in what what is the plc structure you can see 23
in here. 24
is it powered or not or is it run situation or not or is it giving an error or not. 25
These these are the LEDs and this is SS our common cable can connect here and you must connect it to 26
here and x0 to x7. 27
These are inputs as physical and this is Up-Zp, This is a transistor output plc so we need to put 28
in here 24Vdc and 0vdc. 29
And in here we will get our outputs. 30
And here you can see run and stop switch .So we can change. 31
CPU situation from run to stop or stop to run with this switch and in here for example this black 32
area the circle. 33
This is rs232 communication point so we can go on line or connect to plc 34
with our own computer from here and under the PLC you're going to see a for 485 communication socket 35
or connection point for example DVP 28SV , this is we have power led and run led an error 36
led and also battery low led and in here also rs232 and rs485 communication 37
leds while it's communicating these leds are flashing and in here relay output c0 ,c1 these are 38
should be 24 volt and common because what we need. 39
from output what we need to get from output zero Volt or 24v we need to put or connect 40
these voltage value to our outputs common point and in here you can see run and stop switch in here and 41
also connection point of plc and inputs and outputs and the common points and other inputs and you 42
can see while the our models are changing a little bit structure is also changing the how can I say 43
it is giving a lot of opportunity to us in here for example we can use 44
16 input and also in here. 45
I'm counting two four six and eight and twelve output in just one CPU and in here for the SS2 we 46
have just eight input and just six output. 47
So for example you need more than eight input and more than six output and just you want to buy one 48
CPU according to DCP series plc models of the Delta, you can select this one or this one and 49
this one but this is already up to you. 50
This is just an introduction video So for a moment. 51
I am finished here. 52
See you in the next video.
