A Programmable Logic Controller (PLC) receives information from one or more inputs. This semiconductor control device processes the information based on a software program. Finally, it sends an output control signal. The microprocessor based control system performs functions such as timing, logic, sequencing and others. The PLC follows instructions from an operator-defined program.

These intelligent systems provide reliable, high-speed monitoring and control of processes in automated applications. In addition, they are easy to program and configure.

Once the program updates the output, the CPU starts over and the cycle repeats again. The cycle depends on the number of inputs, outputs, and size of the program, while the action will depend on the inputs coming from a variety of sensors.

The input sensors include components such as switches, proximity sensors, photoelectric sensors, pressure switches, level switches, encoders and temperature sensors, while the output devices include actuators, relays, switches, and many more.

PLCs rely on software programs that help them in making the necessary decisions. The PLCs are programmed through a variety of tools, which may differ in ease of use, appearance, and complexity. The most commonly used PLC programming language is Ladder Logic, a graphical software that uses common electrical symbols. Other languages include Function Block Diagram (FBD), Sequential Function Chart (SFC) and Structured Text (ST).

The programming is done on the device such as a computer or handheld device after which it is transferred to the PLC memory using a communication interface.

Selecting a suitable PLC that will address your current and future needs can be a challenge, especially with the large number of different PLCs on the market today. The available PLCs have varying capabilities, physical sizes, complexity, cost, power requirements, scalability and other parameters. Therefore, it is necessary to determine the correct programmable logic controller for your specific application. Special systems can be designed for use in harsh environments.

The Programmable Logic Controller has revolutionized and simplified controls in automation and industrial applications. PLCs are easy to install, wire, program and modify to suit changing application requirements. These control systems are usually available in a wide range of sizes that ensure finding exactly what you need for any application.

“Smart” technology is all the rage right now. However, it’s a bit of a disservice to call the Nest a smart thermostat. A learning thermostat suits the bill better. The Nest system learns your heating and cooling habits, and is able to incorporate the information that it gathers, and the data that it compiles, in order to help you live comfortably in a far more convenient manner. With Nest Sense, the Nest thermostat is able to learn about how long it takes your house to warm up and to cool back down, as well as how it can utilize your existing HVAC equipment in a more efficient manner. You will get monthly energy reports from your Nest, but the truth is that this system is able to help you make your home a more efficient place, without you even having to think about it.

With technology as advanced as the Nest thermostat, you may be wondering what its applications are beyond simply heating and cooling your home in an incredibly convenient and efficient manner. Well, there are many different products which are actually being designed to work with the Nest, as denoted by the “works with Nest” logo. When you see this logo, you’ll know that the products it appears on, from washing machines to lights, are Nest-ready. Contact us today to learn more, or to bring your household further into line with the technology of the future.

There are times when you simply can’t or shouldn’t do certain repairs around your house. Not everybody is trained or cut out to take care of all the little jobs that arise. You need to hire a professional from time to time. One of the professionals you will likely need on occasion is a Glendale electrician. If you have never used an electrician or have had a bad experience in the past and are looking for a new one, how do you know what to look for? The team at The Electric Connection has been helping folks out for years and is here to help you as well. The following characteristics are what you should look for when you need to hire an electrician to take care of work around your home.

• Good reputation-ask your friends, neighbors and family members if they have used a particular company. What was their experience? Do some checking online as well. Angie’s List is a great place to start.

• Professional-an electrician that shows up at your door should look and act professional. A clean uniform is a good sign of a professional contractor. If you are bringing an electrician into your business, a professional appearance is very important.

• Licensed and bonded-this is an absolute must when hiring an electrician. Glendale residents should only allow contractors into their homes or businesses who have the proper licensing through the state as well as a bond to protect you in case there is any damage done to your home.

• Timely-Cable companies are often joked about because of their lack of timeliness, but it isn’t a laughing matter. You are busy and don’t have hours to sit around waiting for an electrician to show up. You need a company that can give you a set window and stick to it.

If you need an electrician, you can call The Electric Connection and find an electrician who meets all of these standards.
