5 SLK memory structure
The SLK memory consists of the following areas:
• Map of the MDT user data area. The user data of the MDT currently in the HF field
can be read and written through this area.
• Map of the MDT register area. Read/write access to the registers of the MDT
currently in the HF field occurs through this area.
• SLK register area. This area contains all system variables used to control how the
SLK functions.
• Data buffer for buffering commands and data for parameterized data exchange.
The individual areas are generally addressed with what is referred to as the SLK
address and depends on the fieldbus system used. Addressing the memory areas is
described in detail in Chapters 7 “Profibus DP”, 8 “Interbus” and 9 “CANopen”.
