following list:

6.5 Hardware Configuration for Profibus

Sequence of the data words (slots) must be:

• Output at first, inputs at second.

• One or two words are accessible at once.

• Output and inputs must have the same memory start address.

6.5.1 Assignment of the PROFIBUS Address

The PROFIBUS address can be assigned via CU1000 or via the hardware configu-

ration tool of the PLC.

To assign the PROFIBUS address via CU1000 select

► "Main Menu -> Settings -> Set up -> Interfaces -> Bus module -> Address".

To assign the PROFIBUS address via hardware configuration tool of the PLC

► refer to the documentation af your PLC.

If you use a Siemens Step 7 you can also
