Process image

The KL2692 is represented in the process image with a minimum of 3 bytes of input data and 3 bytes of output data. These are organized as follows:

Byte offset
(without word alignment)

SB: Status byte
CB: Control byte
DataIN: input word
DataOUT: output word

No compact process image

The KL2692 cannot be operated with compact process image (without control and status bytes), since control and status bytes are required for process data operation of the KL2692 to function correctly. Even if your Bus Coupler is set to compact process image, the KL2692 is represented with its complete process image!
