Beckhoff Panel PC's now with Wonderware preinstalled

One of my absolute favorits is Beckhoff. They offer good value for money (so you can even use it for home automation), a good support and a wide range of products. One of their latest additions is their Panel PC with the Wonderware InTouch HMI software preinstalled.

Plugwise: Be wise, Plug in

I while ago I was looking to optimize energy consumption for a customer's office. I stumbled upon an interesting solution of a Dutch company. 

I managed to reduce the energy consumption with about 20% and was especially charmed by the webserver they supply to make your own custom 'source' interface.

Ciratec is a Belgian company specialized in robot programming. They develloped their own Kuka Editor as an alternative for the more expensive "Kuka OfficeLite". It allows users to write "idiot proof" Kuka programs with an intuitive user interface.

Titan: the world’s strongest robot

Robots – like people – need new challenges. The KUKA “titan” can hold its own among the really big hitters. With a payload capacity of 1000 kilograms and a reach of 3200 mm, it is the largest and strongest 6-axis industrial robot in the world.

OPC Express Interface (Xi)

As a Scada programmer using .NET you often have to work with old COM-objects that force you to modify security settings on the host & client.

Furthermore there are a lot of different tastes (OPC-DA, OPC XML-DA, OPC AE) and not all hardware providers do support them, so you end up develloping new code every time.

I read an interesting article about OPC Xi (Express Interface) which might be promising for the future.
