5.1 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
[
}
48] )
Control byte 1 ( CB1

47] )
1 2 Word DataIN1 DataOUT1
3 4 Byte
Status byte 2 ( SB2
[

49] )
Control byte 2 ( CB2

4 6 Word DataIN2 DataOUT2
6 8 Byte
Status byte 3 ( SB3
[ } 49] )
Control byte 3 ( CB3
[ } 49] )
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 cor-
rectly. Even if your Bus Coupler is set to compact process image, the KL3403 is represented with its
complete process image!
