Process image
Complex process image
In the complex process image the KL2532/KL2552 is represented with at least 6 bytes of input data and 6
bytes of output data. These are organized as follows:
Byte offset (without word
alignment)

SB n: status byte channel n
CB n: Control byte of channel n
DataIN n: Input word of channel n
DataOUT n: Output word of channel n
Complex process image
The KL2532/KL2552 cannot be operated without control bytes, since the control bytes are required
for enabling the channels. Even if your Bus Coupler is set to compact process image, the KL2532/
KL2552 is represented with its control bytes!
