SIMATIC S7-400
Communication
CP 443-5 Extended
■ Overview
• DP V1 master connection of S7-400 to PROFIBUS
• For configuring additional PROFIBUS DP lines
• Communication services:
- PROFIBUS DP
- PG/OP communication
- S7 communication
- S5-compatible communication (SEND/RECEIVE)
• Time-of-day synchronization
• Simple configuration and programming using PROFIBUS
• PG communication between networks through S7 routing
• Easy to integrate into the SIMATIC S7-400 system
• Module replacement without the need for a programming
device.
• Operation in the SIMATIC H system for redundant S7
communication or DP master communication
• Data record routing (PROFIBUS DP)
• Add or change distributed I/O during normal operation
