Mapping

The Bus Terminals occupy addresses within the process image of the controller. The assignment of process
data (input and output data) and parameterization data (control and status bytes) to the control addresses is
called mapping. The type of mapping depends on:
• the fieldbus system used
• the terminal type
• the parameterization of the Bus Coupler (conditions), such as
- compact or complex evaluation
- Intel or Motorola format
- word alignment activated or deactivated
The Bus Couplers (BKxxxx, LCxxxx) and Bus Terminal Controllers (BCxxxx, BXxxxx) are supplied with
certain default settings. The default setting can be changed with the KS2000 configuration software or with a
master configuration software (e.g. TwinCAT System Manager or ComProfibus).
The following tables show the mapping depending on different conditions.
Complex evaluation
In the case of complex evaluation, the serial interface terminals occupy addresses in the input and output
process image. Control and Status words can be accessed.
22-byte process image
Complex evaluation in Intel format
Conditions
Complex evaluation: yes
Motorola format: no
Word alignment: any
