KL2542 - DC motor output stage terminal

Process image

 

Complex mapping

In the complex process image the KL2542 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)
Byte offset (with word alignment*)
Format
Input data
Output data
0

Compact mapping

The KL2542 devices are represented in the compact process image with a minimum of 6 bytes of output data. These are organized as follows:

 
Byte offset (without word alignment)
Byte offset (with word alignment*)
Format

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

 
 

Key

SB n: Status byte of channel n
CB n: Control byte of channel n
DataIN n: Input word of channel n
DataOUT n: Output word of channel n

 
Note
Control-Bytes
The KL2542 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 KL2542 is represented with its control bytes.
