Field Level vs. Management Level – What is that and how to benefit?

When it comes to technologies, we are not only facing a broad variety of technologies, we are also confronted with technologies, which are suitable for the so-called “field level” and “management level”. But what is actually the difference and can either technology satisfy individual needs?

 

“Yes, you can cut your steak with a spoon, but it would not be really handy”.

 

The same answer could be given to the question, whether management level technologies would satisfy the needs of a smart home, or if a field level technologies cover all areas for the facility manager to have full control over his building. So in order to understand the difference, let’s have a quick look at the main differences between a management level technology and the field level technology.

A management level technology is commonly referred as a Building Management System (BMS). Its main purposes are safety, improved comfort and efficient resource consumption. To visualise it – a facility manager, who sits in his control room is using a BMS. Main activities therefore are dispatching and administration as well as working with databases and statistical functions. The cooperation between staff (operators, dispatchers etc.) and system is performed, which is implemented via computers and SCADA-systems.

 

Whilst the BMS can be described as the nerve centre of the building, the Field Level is where the “action” happens, since you can find here the sensors and actuators. Field level devices can be found in smart homes, which do not require a big control centre. Best example for a common field technology is KNX, as KNX is an open technology, provides a big range of devices for individual needs and works perfectly with any other technology, especially with other management level technologies.
