PLC Data Types

There are basically two types of data; discrete and word data. Discrete data is one bit that can be either a '1' or a '0'. Discrete data is used for keypad button inputs and lighting circuit outputs. Word data is 16-bits that represent a fixed or variable number. For example, word data is used for interval timers and any other mathematical calculations.

The Heat is on!

After the successful integration of ProSystÂ's OSGi-based software, the oven will be remotely controllable and maintainable within the house. A web pad could, for example, be used in order to set or change the ovenÂ's baking heat or time. Remote control is made possible via the power supply, so that no new wires have to be installed.

Connected Homes: European Perspective

When you look at the suited technologies, the products and services that are available, and at the determination of the major players to be active, you can only conclude that in Europe, at least we are likely to witness, in the short term, the beginning of a high-growth period in many segments of the market for the Connected Home.

Home Automation on the PC

There is no doubt that one of the next technological frontiers is home automation. The really big question is, once we can do everything we want to do, will it be done with a discrete panel or will it be an application developed for the PC. This article discusses home automation, what's available for the PC today, what we can do and what we can't.

Philips iPronto

All in all ... this is a fascinating device and only the future will tell whether or not the world will embrace it. It combines 3 devices into one ... a remote control, a program guide and a web browser. A future implementation called NetX will have it play a key control role in Philips vision of controlling devices in the home via the wireless home network.

PLC Registers

PLCs offer a fixed amount of registers, depending on the model and configuration. Most modular PLC registers are counted in octal. Its easier for PLCs to count in groups of eight then ten, because eight is an even power of 2.

Powerline Carrier

A Transmitter unit is used at one location to impose a coded signal on the AC power wiring, and a Receiver unit (Receiver Module, Monitor Panel, or Display Panel) is used to receive, decode, provide control, and/or display this signal at other locations. In this system, no new wiring is required for signal transmission.

Product Data & Project Templates

Until the time that there is an accepted product information standard, it is still possible to organize your design, sales and installation processes into standardized business systems that are predictable, repeatable and profitable.

Public Hot Spots: One Truth and Two Myths

Most hot-spot service providers agree that the majority of this market's early adopters are and will continue to be so-called road warriors. These people travel nationally or internationally for professional purposes, and while on the road, they need Internet connections to access their corporate networks and e-mail.

Standards Schmandards

Standards provide a level playing field for both the builder and the installer. They also provide a uniform and predictable infrastructure for the customer. The question is not whether standards will become universal, its when. Builders and installers that strictly implement standards now will develop their reputations early. Installers that skirt standards now will also be developing reputations.

The Market For Ultra-Wideband Solutions

We readily acknowledge the challenges inherent in forecasting a networking solution as broadly-positioned as UWB. However, we simultaneously would caution against the over-hype that has been associated with previous "revolutionary" technologies.

ZigBee Technology: Wireless Control that Simply Works

Up till now there hasn't been a wireless network standard that meets the unique needs of sensors and control devices. Sensors and controls don't need high bandwidth but they do need low latency and very low energy consumption for long battery lives and for large device arrays.

Maverick Powerline 4-Port Bridge

Hook up of the two hubs was as simple as plugging them into an available wall socket and connecting all the network cables to the hubs. After that was done the two hubs automatically found each other and transferring data through my AC wiring was up and running.
