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 such as
- compact or full evaluation
- Intel or Motorola format
- word alignment switched on or off
the parameterization of the KL5152-0000 (KL5151-0050) to compact or complete evaluation (bit R32.6 of the feature register)

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. For information about the contents of the individual bytes please refer to the pages Process image and Control and status byte.

Compact evaluation

For operation with compact process image, you must configure your Bus Coupler to compact mapping and bit R32.6 of the feature register of the KL5152-0000 (KL5151-0050) must be 1_bin.

In this configuration the control bytes are suitable only for process data operation. Register communication is not possible!

Complete evaluation

For operation with complete process image, you must configure your Bus Coupler to complete mapping and bit R32.6 of the feature register of the KL5151-0050 must be 0_bin.

In this configuration you can use the control and status bytes alternatively for register communication or process data operation.

Compact process image on Bus Coupler that is set to complete process image

If the KL5152-0000 (KL5151-0050) is operated on a Bus Coupler that is set by default to complete process image (e.g. Lightbus), but bit R32.6 of the feature register is 1_bin(default setting), the following process image results:

In this configuration you have different control and status bytes for register communication and process data operation. These are only suitable for the respectively specified purpose!

Key

Complete 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 n: Status byte for channel n (appears in the input process image).
CB n: Control byte for channel n (appears in the output process image).

SB n PD: Status byte for channel n, to be used only for process data operation (appears in the input process image)
CB n PD: Control byte for channel n, to be used only for process data operation (appears in the output process image)

SB n RC: Status byte for channel n, to be used only for register communication (appears in the input process image)
CB n RC: Control byte for channel n, to be used only for register communication (appears in the output process image)

DataIN n D0: Channel n, input double word, lowest significant data byte
DataIN n D1: Channel n, input double word, ...
DataIN n D2: Channel n, input double word, ...
DataIN n D3: Channel n, input double word, highest significant data byte

DataOUT n D0: Channel n, output double word, lowest significant data byte
DataOUT n D1: Channel n, output double word, ...
DataOUT n D2: Channel n, output double word, ...
DataOUT n D3: Channel n, output double word, highest significant data byte

reserved: This byte occupies process data memory, although it has no function.
