The CP 343-1 BACnet is the communication module for the connection of SIMATIC S7-300 to Industrial Ethernet and is used for the integration of the SIMATIC S7 into BACnet systems. Via BACnet communications, the CP can also communicate with a third-party system such as heating or ventilation controllers.

With its own processor, the module relieves the CPU of communications tasks and facilitates additional connections.

The CP 343-1 BACnet permits the S7-300 to communicate with:

• PG/PC
• HMI devices
• SIMATIC S5/S7/C7 systems

Possible fields of application:

• Industrial building automation
• HVAC (heating, ventilation and air conditioning) solutions using PLCs at the automation level
• Infrastructure markets
• Airports
• Tunnels
• Totally Integrated Automation (TIA)
• Totally Integrated Power (TIP)
