■

PROFIBUS DP lines can be connected to a SIMATIC PCS 7 au-

tomation system (controller) via up to 4 internal interfaces in the 

CPU and up to 10 additional CP 443-5 Extended communica-

tions processors. 
If a module slot provided in the CPU for the PROFIBUS connec-

tion is still vacant, an IF 964-DP interface module is required in 

addition. When using data set routing with SIMATIC PDM, use of 

the CP 443-5 Extended communications processor is essential 

for the PROFIBUS connection.

■

Advantages of the CP 443-5 Extended communications module:
• Compact design; 9-contact Sub-D socket for connection to 

PROFIBUS DP

• Simple installation

Can be plugged into AS rack slot; connection to the other 

S7-400 modules via backplane bus

• Operation without fan; backup battery or memory submodule 

are not required

■

Order No.
