(1) DC Common:- To complete an electronic circuit we need to give 0 volt supply at same point.
In our circuit we give that supply
at DC common.
One DC common is used after 4
Inputs.
(2) Input/0 to Input/5:- From
0 to 5 we have 6 input pins where we will connect our different types of input
source like Switches, Sliders, Sensors etc.
(3) +24, -24 volt:- Here
we will get the supply from SMPS, which is required for the proper working of
our PLC.
(4)
Ground:- This is our
ground pin which is basically used for earthing purpose.
(5) Output/0 to Output/3:- from
0 to 3 we have four output pins where we will connect our different output
sources like LED, Motor, Buzzer etc.
(i) Among
these four Outputs Two of them are relay and other two are MOSFET TYPE.
(ii) Relay
type are used for slow switching.
(6) NU:- These are our not used
pins where we will connect our different type of external source like relay,
contractor etc.
LED’s
of PLC:-
(I)
RUN:-
A
yellow LED will glow here when our program is properly downloaded & ready
to be execute.
(II)
POWER:-
A yellow LED will glow here when our PLC is getting proper power which is
required for its proper working.
(III)
FAULT:-
A red LED will blink here when there will be any short circuiting in the
circuit and our PLC is not getting proper power supply which is required for
its proper working.
(IV)
FORCE:-
If we forcelly want to ON or OFF any switch through a software then we can use
the option force ON or OFF.
CABLE:- Name
of cable that we use is
AB DF 1.1
0H 485
