Siemens ST PCS 7 · November 2007

■

Overview

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.

■

Benefits

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
