5.1 Data management
The controllere consists of different units:

The CPU (central processing unit) ensures the data transfer between the subsystems. It
manages the remanent flash memory and the volatile RAM memory.

The flash memory is 1 Mbyte large and stores non volatilely...
-
the system configuration including the AS-i configurations,
-
the r un t ime s ystem (RTS),
-
the PLC program (must be explicitly stored there!),
-
the remanent data.

The operating system and the PLC programs run in the SRAM memory, now also 1
Mbyte large, after power-on of the device.

The AS-i masters feature a separate microcontroller and communicate with the connected slave
modules on the AS-i bus according to the AS-i specification.

A text/graphics display in the controllere enables a detailed system diagnosis. Operating the
device with the four keys is easy to learn.
