Good morning everyone.

What is happening to our class

I come in the moment everybody is ready. I can't continue if the class is not active

I am already forgetting all that had been thought. Geez

This class is free, reason people don't value it.

Southboy:

Screenshot the ones you like. Create a folder on your phone and keep them there

You can make it paid, I will pay but make d money no too much ooo

Southboy:

Consider another approach for the sake of people that still want to learn

If I have about 4 more serious people like you, I will continue. Am not interested in being paid. The class is free. My time is very precious to me

Please continue Boss. Most of us are silent readers. Thanks

Continue pls, we are following silently

Good morning sir. Thank you very much for your kindness and generosity on this topic of automation. I just came across this post. This platform is good but it limits alots of learning inputs. A few demo video clips on automation would be inspiring and increase understanding of the topics but it cannot be done here. I don't know if you will consider another platform that enables video sharing like WhatsApp or Telegram. Even voice notes will save you alot of time.
Thank you sir for your consideration

please don't be a silent follower. Even if you come in one a day to drop a comment it will go a long way to encourage out lecturer.

I'm here, just joined tho.

Keep it coming guyz, let's make this happen. Two more peepz and we should be good to go

Good evening

I jus came across this post and I’m really interested in this automation skill. I’ve worked in industrial setting and familiar with some electrical devices, would love to learn more from this opportunity

You can't understand this program without very active participation, the reason why I view it as waste of my precious time and energy.
Even my powerful course rep @southboy said he has lost memory of some things discussed, that shows lack of assimilation.
Please let only the serious guys indicate their interest not the silent followers

If you want the serious people to indicate interest that means you will need another platform because I really want to learn Automation

I really understand everything you have taught so far, just that I have not been doing any more research and it's feels like I am already letting go.

Individual schedule may not permit us to follow up like this..

I’ll suggest you make a time frame that interested participants can stick to or have a telegram group it

Also if we can have an In-class training, it will be more interactive and practical knowledge can be passed across. Please consider this

Plz am interested

I nominate @doghorp as assistant course rep to support @southboy in moving the class forward. @southboy has been performing excellently in advancing the group. Two is better than one as stated in the Bible

I have noted all the suggestions and will act on them. All we have been doing is background work, if you have followed up to this point, you will definitely catch up as we enter deep into the program gradually.
I will post videos to illustrate certain points only when am satisfied by the number of followers to justify the time and energy in creating such practical videos.
I have gained this uncommon knowledge and want to pass it across, all I need is seriousness and commitments.
I want to say it again, the training is free

Ladder Logic programming.
Consider the diagram below
We have entered into programming
What do understand from this logic program?
I stop here until I get minimum of 5 inputs from my students

Let's explain the ladder diagram

Please refer to the ladder diagram above.
You will notice two colours; green and black. The two colours shows that the user is on online mode. When offline, the entire diagram turns black.
The diagram looks like a climbing ladder hence the name ladder logic.
There is a special computer design by the PLC manufacturer for programming, this computer is called PG (programmer). The PG (Laptop) is very expensive and may cost above #15m.

When there is a problem on the line( many machines put together) that could not be solved by operators, electricians, mechanics, engineers on duty, the next point of call will be the automation guy. You're expected to login your PG to find out the fault.
The moment you go online, you see the signal flow on the PLC. The signal flows from the left side to the right side. The inputs are positioned on the left while output on the right.
The green color indicate the signal while the black color indicate where the signal flow stopped.
Any confusion or questions at this point

Noted @ytdivine

Thanks for sharing your experiences, knowledge and skills . This is awesome , am interested.
Keep the good work Engr.

In automation, we can group the system into three major units
a, Field devices (sensing devices)
b. Actuators ( action devices eg motors)
c. Program (written instructions)

The signals from the field devices form the input to the PLC while the output from the PLC acts on the actuators.
The output depends on the written logic programs.
Now let's illustrate with this example.
I entered into a hotel named Park inn in saint Petersburg Russia, the main entrance door immediately opened on it's own without human assistance, it closed the moment I entered inside. I have not experience this in Nigeria, maybe such system might exist, I don't know.
Let's explain the automatic door.
It has two sensors, one at the outside, the second position inside. These two sensors are referred as contacts inside the logic program. The door also has a motor(actuator) that open and close it.
Motor action is dependent on the output signal from the PLC.
Let's call the first sensor input A and the second sensor input B.
The moment you stand in front of the door, the sensor detects your presence and send a 24vdc signal to the PLC, the input A/Contact is activated and the coil( output) is energized, the door opens.
The moment you enter inside, the input B/Contact is activated, thereby resetting the coil(output), the door returns back(closed)
Many confusions, feel free to ask your questions.

Maybe it's just me but I can't see the ladder diagram you mentioned
