Slide 1: | Welcome to the spoken tutorial on OpenPLC Switchboard module. |
Slide 2: Learning Objectives
We will learn about
|
In this tutorial, we will learn about OpenPLC Switchboard module. |
Slide 3: System Requirements
|
To record this tutorial I am using:
|
Slide 4: Pre-requisites |
|
Slide 5: Switchboard
The goal of this module is to get familiarized with different types of switches In particular their usage in the real time applications in industries |
The goal of this module is to get familiarized with different types of switches.
In particular their usage in the real time applications in industries. |
Slide 6: Main Components
|
This module has
|
switchboard.jpg | This is the Switchboard module. |
Slide 7: Types of Switches:
|
In this module, there are three kinds of switches available.
They are Normally Open, Normally Closed and Latched action switches. |
switchboard.jpg ( to show with arrow) | Normally Open is represented as NO and Normally Closed is represented as NC.
Latched action switches are represented as L. |
SB-switches.png | We will now look at their arrangement on the module from bottom to top. |
SB-switches.png
Highlight Latch switches Then NC and then NO |
At the bottom, we have two Latched action switches.
Above that we have 4 Normally Closed and then 4 Normally Open switches. |
SB-leds.png | Above these switches we have LEDs corresponding to each switch.
The LEDs are arranged in the same order as that of switches. |
Each LED glow indicates a corresponding switch press. | |
SB-connectors.png | On the top we have female berg connectors for connections. |
SB-connectors-z.png
Point to each particular pin |
Next, we will see about the pins.
Starting from the right, the first two pins are GND and 5V respectively. These are the input power pins of this module. Then we have 4 pins for 4 NO switches and 4 pins for 4 NC switches. The last 2 pins are for 2 latched action switches. |
Slide 8: Important Note
|
NO and Latched action switches must be connected to the I/Os of the microcontroller.
Only then the LEDs of the corresponding switches will work. Note that LEDs of NC switches will work, even if they are not connected to I/Os of the microcontroller. |
Now, we’ll learn how each type of the switch works. | |
Slide 9: Normally Open switch
|
The output pin of a NO switch will read logic 0 when it is not pressed.
When the switch is pressed, the output pin will read 5V. This is due to the supply from the microcontroller’s internal pull up register. |
Slide 10: Normally Closed switch
|
The output pin of a NC switch will read 5V when it is not pressed.
This is due to the supply from the microcontroller’s internal pull up register. Upon switch press, the output pin will read logic 0 or Ground. |
Slide 11: Latched action switch
The output pin will read 0V, when it is pressed for the second time |
It is basically a push-to-make, push-to-break type of switch.
That is, the output pin will read 5V, when it is pressed for the first time. The output pin will read 0V, when it is pressed for the second time. Working of the LED of a latched action switch corresponds to that of a NO switch. |
Slide 12:How can the Switchboard module be powered?
Switchboard module can be powered using the output power pins of the Mainboard |
How can the Switchboard module be powered?
It can be powered using the output power pins of the Mainboard. |
We have learnt about the different types of switches in the Switchboard module. | |
This brings us to the end of the tutorial.
Let us summarize. | |
