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.

Compact evaluation

	Operation with a compact process image is not possible Operation of the KL6031 / KL6041 with a compact process image (without Control and Status bytes) is not possible, because Control and Status bytes are required for meaningful process data mode of the KL6031 / KL6041. Even if you set your Bus Coupler to the compact process image, the KL6031 / KL6041 will still be represented with a complete process image!

Key

Complex evaluation: In addition to the process data, the control and status bytes are also mapped into the address space.
Motorola format: Motorola or Intel format can be set.
Word alignment: In order for the channel address range to commence at a word boundary, empty bytes are inserted into the process image as appropriate.
SB / SW: Status byte / Status word for channel n (appears in the input process image)
CB / CW: Control byte for channel n (appears in the output process image)
reserved: This byte is assigned to the process data memory, although it has no function.
