About This Communication Processor

This product is a Communication Processor (CP), often referred to as a **PROFIBUS CP** or **S7-300 Communications Module**. The CP 343-5 is designed to operate in an S7-300 rack and manages the PLC’s connection to a PROFIBUS network. It supports a variety of communication services, including the complex **PROFIBUS FMS** (Fieldbus Message Specification) protocol for data exchange between masters, as well as high-speed **PG/OP communication** (for programming/operator panels). By handling these tasks, the module frees up the CPU’s processing power for core automation logic, significantly improving overall system responsiveness.

Applications

This communication processor is suitable for integrating S7-300 PLCs into various industrial networks and distributed control systems, including:

• Centralized Control of Distributed PROFIBUS I/O
• Networking S7-300 PLCs with other automation controllers (FMS client/server)
• Connecting HMIs and Programming Devices (PG/OP communication)
• Process Control and Manufacturing Automation requiring real-time data exchange
