7BCOMMUNICATION IN SIMATIC S7 

 

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. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Table 8-1 

Allocation of the peripheral area 

 

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. 

The details are described in a separate chapter (see Chapter 

9 Communication 

with other systems 

).
