PLC Programming for Dancing Light - PLC Programming

Many users mailed us for making the PLC program for the dancing light, so here we will see the PLC Logic for making a fancy light decoration system. This PLC program can be used for lighting systems in house or for any festive celebration time. We will see here in detail the logic of PLC programming and the steps involved in making the PLC Program.


PLC Programming for Dancing Light - PLC Programming



Here in this PLC Program we are considering six numbers of LED, 1 start push button, 1 stop push button and 1 selector switch. We will write the PLC program for 2 different mode i.e the LED's will glow in two different pattern.

Mode 1 Pattern of LED Glowing:- While writing this PLC logic we have made the PLC program in such a way that when we will push the Start button then LED 1 will glow, after 1 second LED 2 will glow and again after 1 second LED 3 will glow and so ON and after 6th LED the cycle will start again. The number of LED's can be more as per the need and application.


See the Below table for better understanding.


Time -----------LED1 ------------LED2---------LED3---------LED4--------LED5------------LED6
T=0sec ---------OFF--------------OFF----------OFF----------OFF----------OFF-------------OFF
T=1sec ---------ON --------------OFF----------OFF----------OFF---------OFF-------------OFF
T=2sec ---------ON --------------ON-----------OFF-----------OFF---------OFF-------------OFF
T=3sec ---------ON --------------ON-----------ON------------OFF---------OFF-------------OFF
T=4sec ---------ON --------------ON-----------ON------------ON----------OFF-------------OFF
T=5sec ---------ON --------------ON-----------ON------------ON----------ON--------------OFF
T=5sec ---------ON --------------ON-----------ON------------ON----------ON--------------ON

and then again the cycle resets after every 6 seconds.

Mode 2 Pattern of LED Glowing :-

In the second mode , which will be on when we will select it by selector switch the LED 1 and LED6 will glow first for 1 second then LED 2 and LED 5 will glow and then LED 3 and LED 4 .

See below table for a clear understanding.

Time -----------LED1 ------------LED2---------LED3---------LED4--------LED5------------LED6
T=0sec ---------OFF--------------OFF----------OFF----------OFF----------OFF-------------OFF
T=1sec ---------ON --------------OFF----------OFF----------OFF----------OFF--------------ON
T=2sec ---------ON --------------ON-----------OFF----------OFF----------ON---------------ON
T=3sec ---------ON --------------ON-----------ON------------ON----------ON---------------ON

And then after 3 seconds the cycle resets.

PLC Logic Development for Dancing Light



INPUTS

0.0 --- Start Push Button -- (NO)
0.1 --- Stop Push Button --- (NC)
0.2 --- Selector Switch --- (1 pole)

OUTPUTS

100.0 ------------- LED 1
100.1 ------------- LED 2
100.2 ------------- LED 3
100.3 ------------- LED 4
100.4 ------------- LED 5
100.5 ------------- LED 6

We have considered only 6 LED here only, however the PLC Programming can be extended for any numbers of LED you want and also the glowing pattern can be changed as you like. If you have some any other pattern in mind and want to make PLC Logic according to that then tell us , we will make for you.

You can download the PLC Program below. We have attached both .pdf and cx-programmer file.

How to Connect Omron Rotary Encoder to PLC

How to Connect Omron Rotary Encoder to PLC
Encoders finds their application in various applications in industry. From Instrumentation point of view we can see Encoder as a device which provide us the pulses for rotatory movement.In Most of the applications it is used to provide the feedback and thus a better controlling.



Omron Rotary encoder E6B2 comes with open collector output and as well as line driver output. It has external shaft dia up to 40mm and it has a resolution of up to 2000PPR.


Some may want to know what is PPR in encoders ?? well PPR stands for Pulse Per Revolution i.e the number of pulses it will be giving in one full revolution.Also as per our need we can select either PNP or NPN type output. Generally in all the cases we need to interface the encoder with PLC to receive the PULSES.


The use of encoders in Automation is for detecting/calculating the length or distance traveled with the input from encoder pulses , for measuring the speed or for high-processing of data. For more detail on encoders you can see here.



How to Connect Encoder to PLC?


For connecting the Encoder to our PLC we have to make sure that our PLC accepts high speed counter inputs and we have to connect the encoder accordingly to that terminals only. Omron PLC CP1E/CP1H have 4 high speed counter inputs and we can connect up to 4/6 encoders.
Omron encoder E6B2 series have 5 wires and of different colour. Make connections as depicted below.


Wire Colour -------------------------------------------------------------Type

Brown------------------------------------------------------------------- + 24 V DC
Blue ------------------------------------------------------------------- 0 V Dc
Black ------------------------------------------------------------------ Output Phase A
White ------------------------------------------------------------------ Ouput Phase B
Orange ----------------------------------------------------------------- Phase Z

 
So connect your Encoder accordingly as shown above. Here we will tell you how to interface it with PLC. We will take example of OMRON PLC CP1E. We have to just connect 3 wires to PLC high speed counter Terminals and configure them in the software for Receiving the Pulses.
Interfacing the Encoder with Omron PLC CP1E:-

 

We will take example here as connecting the encoder to High speed counter 0.

 

Encoder Side--------------------------------------------------------PLC Side

Black-------------------------------------------------------------- 0.0
White-------------------------------------------------------------- 0.1
Orange------------------------------------------------------------- 0.4

Similarly we can connect it to any high speed counter input , just we have to check what are the terminals assigned for that HIGH Speed Counter in PLC.

After making the connections we have to write the suitable PLC Program for the reading of Pulses and processing the PV value of Encoder.

PLC Programming and necessary settings in CX-Programmer will be discussed in next post. So just reading here and also you can subscribe to get all related updates in yours Inbox. If you are facing any problem in connecting up your encoder then feel free to write in comment sections. PLC Programming for Encoder will be discussed in next post.
