Process image

The KM4602 terminal module represents itself in the process image with a maximum of 6 bytes of input data and 6 bytes of output data. These are organized as follows:

• 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 DataOUT1 and DataOUT4. Input data words DataIN1 and DataIN4 are not used.
