DP process image Via the User_Prm_Data the terminals can be split up between the PLC
process image and DP process image (evaluation takes place in the
higher-level system). One area each in the PLC input or output process
image can also be defined for transfer via the PROFIBUS. In this case, the
data is copied byte-by-byte.
Example:
1. KL1002
2. KL2012
3. KL3002
4. KL6021 in standard format
The KL6021 is to be processed by a higher-level system and must
therefore be assigned to the DP process image.
User_Prm_Data[15] = 00101010B
The PLC input bytes 17-23 and the PLC output bytes 22-26 are also to be
transferred via the Profibus.
