Process image

The KL2535 and KL2545 appear in the complex process image with at least 6 bytes of input and 6 bytes of
output data. These are organized as follows:
Byte offset (without word
alignment)
0

The KL2535 and KL2545 appear in the complex process image with at least 6 bytes of output data. These
are organized as follows:
Byte offset (without word
alignment)
0
1

*) Word alignment: The Bus Coupler places values on even byte addresses
Legend
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
Process image
It is not possible for the KL2535 or KL2545 to operate without control bytes, since the control bytes
are required to enable the channels. Even if you adjust your bus coupler to the compact process im-
age, the KL2535 and KL2545 will still be represented with their control bytes!
