Process image
The terminals KL3132, KL3162, KL3142, KL3152 KL3172 and KL3148 are represented in the process image with a maximum of 6 bytes of input data and 6 bytes of output data. These are organized as follows:
Format | Input data | Output data |
---|---|---|
Byte | ||
Word | DataIN1 | DataOUT1 |
Byte | ||
Word | DataIN2 | DataOUT2 |
Key
SB n: Status byte for channel n
CB n: Control byte for channel n
DataIN n: Input data word channel n
DataOUT n: Output data word channel n
- Please refer to the Mapping page for the allocation of the bytes and words to the addresses of the controller.
- The meaning of the control and status bytes is explained in Control and status bytes.
- In process data mode the analog values are transferred in output data words DataIN1 and DataIN2. Input data words DataOUT1 and DataOUT2 are not used.
Representation of the analog values
