My career in automation started in the plastic industry . Fortunate to have a relative with years of experience in the plastic industry , I got tutored by him . As A Nigerian from an IBO tribe ( We have a learning system thriving on mentorship ) It became clear to me that every skill has a secrete .Because I was relative it took less time to discover many aspect of our circuit diagram ,hidden away ,but understood by only students within the circle .Our controls performed better than others .After Years working with Siemens controller , I'm to discover the reason was a fantastic automation project carefully sectioned and designed with sub -routine principle using relays and contactor as primary control components . The need for Developing relay logic controls for injection /blow moulding ,or utility machine arose from small scale industry not able to replace an electronic controller when the controller breaks down . Our services provided opportunity for machine thought to no longer be of use to come back to life at cheaper cost -modelling the original controller .If you have a machine lying waste because Electronic technicians can't figure out why the controller malfunctions or you can't afford to import a new controller , a relay controlled system comes in handy ,especially where a cost effective solution is desired . So if you have an old machine with a working mechanical system , short of control ,you wish to bring back to the shop floor - get in touch . If you wish to learn and understand the principle involved in automating a system ,you have an opportunity. I am willing to take you through from the very basic -Relay logic to advance level automating with Siemens S7 300. |
Have you heard of geevas.com.Its presently the most ruthless ponzi site built by scammers . A friend of mine told me how he managed to speak with one of the admins ,discussion went sour he was called mugu.Do not fall for them They just launched a 200k above package and are encouraging people to pledge .There hide behind the internet telling people that they are presently paying people who PH 200k above its a lie.Don't fall victim many are already crying . |

Hackers ! Im not a programmer ,so hacking is not my thing .But those of you programmers out there thinking of venturing into hacking - A piece of advice . 1. Build your own device. Have control what you hack with. Have an official device you surf with and an unofficial device you hack with. Avoid hardware as e g Intel in your unofficial device you hack with. 2. Familiarize with Network architecture. You need to know in your finger tips the architecture of your target. Therefore knowledge of e g different OS is very good. 3.Learn how VM works. Learn which OS you have on bare metal and which in VM. Learn how to create VPN chains. Learn how to go online without trace. Learn electronics. Learn hack electronics. In other words create your own devices. 4.You need to know ICT Security.Also ICT Forensics is good to know. 5.You need to know learn some high level languages. Eg.Python, C, C#, C++, Java, PHP etc 6.Learn Cryptography. Learn and understand linear algebra, calculus, probability and how to use them . Make your own programs. Have control.

Why you should Learn To Write The Python Language . Two days ago I started studying python.Honestly its not the dangerous reptile I thought it is.on the internet , I have on several occasion breezed pass a hand full of post trying to convince readers to learn python, projecting it as a would be high paying programming language in the nearest future.one of the primary reason I stayad away from python is the idea the name projects " python " . A program that takes the name of one of the most dangerous reptiles in the history of planet earth ,must be dangerous it self.My understanding made me belief that python is one of the most difficult programming language in existence.I have a basic knowledge of C and assembly languages.It enabled me program micro-controller...............click link.@ http://www.atmalz.com/Thread-PYTHON-AND-THE-RASPBERRY-PIE |
Protecting Control Systems. How can anyone let their PLC or other crucial part of their factory be open to the prying 'eyes' of the world? I know I've written about this topic before but it needs further coverage. As such, let's take a look at how to protect our systems. 1- Connected to the Internet? Ask yourself a basic question. Must you have the PLC connected to the Internet? I mean MUST you have it connected? Maybe so. Maybe you need to login to the system for status updates or troubleshooting as it's in a remote location. Or maybe you can't get there at all times of the day or night to fix an issue so you do it by logging in remotely. If you must then you must. If you can do fine without remote capability do not install a connection to the outside world. 2- Create a private world If the systems must be connected to the outside world they should exist in their own world. In other words, there should be a separate network for the business and another for the control system. As we all know, the business network has too much risk flying along it with people using their computers to access the Internet and pickup malware and other bad stuff. Don't put your control systems on the business network. That's just asking for trouble. No 3 |
Hello guys can anybody help me with circuit diagram for preventing motor from running dry.I found some thing useful on www.atmalz.com but I need a circuit diagram. |
PROFIBUS TERMINATION Some of us may have taken note of the red dip switch on the profibus cable but may not fully understand its role .Others may not have taken note of the switch at all. The red dip switch on the profibus connector prevents signal deflection that results from unterminated profibus connection. Now let's say you have a bus with one master and two slaves .At what position will the profibus switches of the connectors be at ?Which of them will be Off / On ? www.atmalz.com . |
ANALYSIS . The image attached to this write up is a basic compressor electrical control .The control is a simple two rungs ladder logic control circuit. Recall that our objective was to : "to start our compressor motor "IF compressor stored pressure is BELOW allowed pressure limit and switch it OFF "IF" compressor accumulated pressure is ABOVE set limit" .Our primary objective therefore is to develop an equivalent logic circuit for the statement highlighted in yellow . Legend : XCB = Miniature CB XOFF = Stop switch XStart = Start Switch YC1 = NO contact of YC1 contactor. YC1 =Main Contactor Coil XPR_SW. = pressure switch. XOL = Overload relay YR1 = Recycle relay YR1 = Recycle relay contact YC1. = contactor auxiliary contact. See ladder logic circuit. |
A look At The Electromagnetic/Mechanical Relay ,Contactor And Overload Relay . Difference Between An Electromagnetic / Mechanical relay And A contactor . "Have you ever seen a relay" ? Yes sir I replied .It was an Interview.I was before a five man panel ,headed by a stone faced self acclaimed automation Engineer, I believe .The other members seem to know nothing about the business of the day ,but i was sure they will gladly laugh at the foolishly of the interviewed ,when ever it is clearly demostrated. "What about the contactor have you ever used it ? " He asked .The questions came as a surprise , I had mixed feelings.First I was kind of disappointed some one wants me to talk about contactor's and relays in an Automation Engineering interview but on the other hand I was kind of relieved - the questions were elementary."Can you tell us the difference between a contactor and a relay "? Down inside of me I was like wao ! This man must be tricky or smart .His question turned out to be an elementary question that could throw you off balance if you are not properly grounded . Well he is not ,in fact he turned out to be the dumbest interviewer I ever meet. I told the panel " there is no major difference between the relay and the contactor,I replied CONTINUE |

Direct /Online Motor Starter. Motor Starters : Electrical Motor starters are controls designed to start and stop(ON and OFF) industrial or domestic Electrical motors .The basic rule guiding the design of an industrial or domestic motor starter is that ; Electrical motors must not start automatically .This simply means that an electric motor must be on OFF mode immediately after power outage and must remain OFF after restoration . A human operator must be responsible for switching an electric motor ON and OFF .Their are different types of motor starters ,but here we will be considering the design and development of an online motor starter . What Is An Online Starter ? An online motor starter is also known as a direct motor starter .It is a a kind of motor control circuit mostly used for starting motors that are rated bellow 10hp(horse power) .Electrical motors run on low and high speed . An electric motor connected to run on low speed is on a star configuration why motors running on high speed are on delta. Using a direct starter and direct configuration implies that the electric motor will start at its full speed. Direct starters should be used on motors not exceeding 10 horsepower(The horse power of a motor is directly proportional to its speed ). Components Required To Design An Online mother starter . To Develop A Direct/Online Starter you need The following Electrical Components: Control diagram |
Basic Air Compressor Control Panel Design And Wiring . What Is An Air Compressor . An air compressor is a device that generates and saves compressed air . The potential energy converted from power generated from machines like , the electric motor or diesel engine is compressed in form of air .The compressed air accumulates in a pressure tank attached to the air compressor ,unit up to a safe running limit .When the set limit is reached the compressor switches off .The compressor maintains its OFF mode until accumulated pressure drops bellow the safe limit .When compressed pressure drops , the compressor turns ON by itself.

Rossikk:What's the difference between killing with nuclear weapon ,Auto revolvers, missile luncher etc.How many have died by gun in the middle east.If trump will sanitize the system why not let him.Black don't just hate Donald trump because they think he is racist ,but because thy know he will clamp down on criminal activities just as Muslims know Trump will be a game changer . Obama and Clinton escalated terrorism. Clinton refused to sign a document tagging boko haram terror organization.The rest is history ! |
Rossikk:The Clinton's have used more than nuclear weapons.She knows too much about American politics.Clinton may end up like President buhari who feels the need to do the right thing now ,but will always be undermined by a cabal know his secrete .They are all committed one way or the other. |
I think Trump stands a better chance .World security challenges has made it easy for him.America wants to be sure they can freely hangout without being attacked. - that's what trump is offering.Believe it or not more Americans are buying ! |

ELECTRICAL GRAIN DRYER. Farmers must turn to Commercial grain Drying machine to maximise output and reduce damages. In African markets and streets ,women smoking fish for sale is a common sight . With fire under an open bottomed basin and net like frame on top of the basin there victims end up dried after hours of exposure to flame and smoke. Exposing agricultural products to sun light is also a common sight in Nigeria .This method is most effective in the Northern part of the Nigeria ,where temperatures are up to 50 degree centigrade some times but low in the south eastern part of Nigeria. Granted these local methods of drying food commodities are less expensive but they are also slow and consumes a lot of energy. For example the cocoa seed :The cocoa seed must be exposed to a degree of heat to reduce moisture. In Nigeria,Local farmers expose Cocoa bean to sun ,this requires bringing the bean out in the morning hours and bagging them back to store in the evening . It takes days of exposure to reduce moisture. Commercial farmers need a quick and faster method of preserving their products. Electrical \Electronic grain Dryers. Electrical dryers are more effective and requires less time to reduce or completely eliminate moisture. Farmers in a region can contribute, to own one if individual cannot afford to buy them. *What You Need To Build A commercial grain Dryer. www.atmalz.com/showthread.php?tid=855 |

The Ace PLC is not just cheap per say.It comes with a free software that enables you implement a ladder logic control. The cheapest in its category cost 49 $ ,which is less than 25 thousand Naira. It also has a free HMI software that could be use to monitor field variables. https://www.velocio.net/wp-content/uploads/2014/01/Top-Logo.png If you will like to ask questions or read related article www.atmalz.com Engineering category : |
Northern politicians are the most corrupt in Nigeria. Bellow are names of 20 most corrupt politician and leaders of Nigeria. Let's be honest most of us may not be surprise to see some of the names on this list, rather having majority of them come from the Northern parts of the country is disappointing. The so called Muslims with supposed high moral and ethical standards.I expected lots of Easterners especially from the Igbo Majority tribe but behold, one Igbo man did not make the list. The northern leaders have subjected their so called brothers to abject poverty which has contributed to illiteracy and terrorism. These blind followers will willingly bow "rankadede" to one of these oppressors for less than a day meal, which in turn equips these poor masses in ignorance -to slave ,kill and live for them. Every thing is not wrong with Nigeria -This list is a prove that the North just, like every part of Nigeria needs revolution the most-It doesn't matter what you call it -they shame us. See the list of 20 most corrupt Nigerians for your self.www.atmalz.com |

Toktee: Can you tell me how and when the woman call mary died?she hard other kids they where not believers as at then. |
dejilg: Really? Peter started the catholic church? Why do this catholic zealots spread the myths of their church? Ok if so, can u give us any non catholic back up of Peter founding the Catholic church? Atleast we have many sources confirming James the Brother of the Lord with the Christian Copts of Egypt!Catholic did not start with peter.The bible always refere to the gathering of christains as the church in() or congregation. The romans where fierce persecutors of christains.it was Constantine that made christainity their official religion because he percievd it wil support his political goals.The ramans worshipd alort of deities but accepts one as supperior.whn Constantine acceptd christainity he knew it wil be difficult to bring others so he allomd them to come with their deity.so startd most of the catholic beleive and practice.instead of worshiping an egyptian godess by what its knwn for they cal it mary .Their are alort of them i point this as it relate to the thread. |
jdilight: sorry mary holds no intercessory office in heaven. Jesus himself said,"ask the father anything in my name". so y go through mary. is the father wicked or what. Why can't we go to the father direct as he said we should. l want to know y we need a mediator?Jesus did not perform the first mirracle at mery's request.Remember jesus asked'Woman,what busines do i have with' men has only being tool for accomplishing Gods will so was mary.I wonder why Abraham like mary.can we say she is more faithful.Abrahams faith in our creator is hardly comparable.why not ask him to rather intercede for us for sure without him their won't be a mary.he is the root. |
