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) |
Byte offset (with 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
 | 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 image, the KL2535 and KL2545 will still be represented with their control bytes! |
