Process image

The KL3403 is represented in the process image with a minimum of 9 bytes of input data and 9 bytes of output data. These are organized as follows:

Byte offset (without word alignment*)	Byte offset (with word alignment*)	Format	Input data	Output data
0	0	Byte	Status byte 1 (SB1)	Control byte 1 (CB1)
1	2	Word	DataIN1	DataOUT1
3	4	Byte	Status byte 2 (SB2)	Control byte 2 (CB2)
4	6	Word	DataIN2	DataOUT2
6	8	Byte	Status byte 3 (SB3)	Control byte 3 (CB3)
7	10	Word	DataIN3	DataOUT3

*) Word alignment: The Bus Coupler places values on even byte addresses

	No compact process image The KL3403 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 KL3403 to function correctly. Even if your Bus Coupler is set to compact process image, the KL3403 is represented with its complete process image!
