8.7 Peripheral area for SFC, SFB, FB communication

In simple applications where only the weight values and status information is to be
read, the user can access the peripheral address of the SIWAREX module directly.
The following table shows the assignment of the peripheral area when
communication to "SFC, SFB, FB" is selected in the HW config. Byte "0"
corresponds to the address of the SIWAREX U module in the HW config.

8.8 Peripheral area for I/O communication
Communication via the peripheral area can be used when "I/O" communication has
been selected in the HW config for the communication with external systems when
using the peripheral system ET200 M.
