SIMATIC S7-400
Communication
CP 443-5 Basic
■ Overview
• Master connection of the S7-400 to PROFIBUS
• Communication services:
- PG/OP communication
- S7 communication
- S5-compatible communication (SEND/RECEIVE)
- PROFIBUS FMS
• 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 changeover without PG
• Operation in the SIMATIC H system for redundant S7
