Front End Processor
A Front End Processor (FEP) is a computer that provides additional connections between building level
devices (such as field panels) and Desigo CC. By providing additional connections to the building level
network, an FEP enables load balancing for the network-based processing for a Desigo CC system.
System Dimensioning Guide
Desigo CC covers a wide variety of solutions so that it is impossible to define simple rules for determining
the size. Therefore, a system dimensioning tool is available that estimates the system size and disk storage
space on the basis of information available at the time of the offer, e.g., the number and type of physical
points and the expected history data base contents.

Graphics
The Graphics application allows you to view the configured graphics representing your facility or
equipment. You can change the current state of an object's properties from a graphic, filter your view of a
graphic by discipline and section and you can zoom in and out for greater detail or for a birds-eye overview.
Trends
All available process data of a system can be recorded and applied to operational optimization. This lets
you record information on plant states, temperature curves, switching states, and counter values in a form
that is suitable for your purposes. The measured value data can be displayed and evaluated graphically.
Online trend records real-time values from your plant and displays them graphically in a Trend View. If a
value changes, the data values are sent to the trend application. Offline trend data is used for the longer-
term storage and retrieval of historical data for the analysis of entire plants or single processes. With
offline trend, data is recorded directly in the automation station.
Trend and system activity data is stored in a Microsoft SQL Server database. Microsoft SQL Server Express
is included with the Desigo CC software, and can be upgraded as required. The Trend Comparison View
lets you time-shift the trend view to compare data at different times for quick analysis of changing
conditions.
