  SIMATIC IPC847D 
170  Operating Instructions, 01/2014, A5E32997454-AA 
Data traffic is routed via the communication processor to several SIMATIC S7 PROFINET IO 
devices, ET 200S over Industrial Ethernet.  
 
CP 1616 onboard as IO device 
The following diagram shows a typical application: Two PCs each with a CP as a PROFINET 
IO device on the IO device layer.  
A PC with a CP as PROFINET IO controller, a SIMATIC S7-400 with a CP 443-1 as 
PROFINET IO controller and two SIMATIC S7 ET 200S PROFINET IO devices are also 
connected in the network.  
The IO base device user program runs on the IO device PC. This program accesses the 
functions of the IO base user program interface. Data traffic is routed via the CP 1616 
onboard communication processor to a PC as PROFINET IO controller, or to an S7-400 
automation system with CP 443-1 over Industrial Ethernet.
