Process image
In the process image, the KL3356 is always represented with 6 bytes of input data and 6 bytes of output data.
Format | Input data | Output data |
|---|---|---|
Byte | Status byte (SB1) | Control byte (CB1) |
Word | DataIN1 | DataOUT1 |
Byte | Status byte (SB2) | Control byte (CB2) |
Word | DataIN2 | DataOUT (this is not used and is not displayed by the TwinCAT System Manager) |
- The input data word DataIN1 and the output data word DataOUT1 are only used for register communication.
- In process data mode, the input data word DataIN2 transmits the weight, and the output data word DataOUT2 is not used.
- Please refer to the Mapping page for the assignment 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.
 | Compact process image not possible The KL3356 cannot be operated with compact process image (without control and status bytes), since control and status bytes are required for process data mode of the KL3356 to function correctly. Even if your Bus Coupler is set to compact process image, the KL3356 is represented with its complete process image! |
