Siemens CP 343-1 BACnet – 6FL4343-1CX10-0XE0 CM1N9291en_02
Building Technologies 17 Sep 2009
•
Engineering with NCM S7 for Ethernet (integrateable as of STEP 7 Version
V5.4 SP4 HF6 ).
• Cross-network PD/OP communications using S7 routing.
• Diagnostic functions in STEP 7 and via web browser.
• Direct integration of S7-300 in complex plants over Ethernet at 100 Mbps.
• Ideal for deployment on line-structure networks using integrated 2-port
real-time switch.
• Investment protection for existing plants by integrating SIMATIC S7-300
via S5-compatible communications.
• Flexible use thanks to free port selection.
• Saving space required for integration thanks to single-width design.
• Remote programming possible also via telephone network (e.g. ISDN)
thanks to TCP/IP's WAN properties.
• Multicast function to reach many members.
• Access of max. 4 operating and monitoring systems to SIMATIC S7-300.
• Use of socket interface in partner system possible without RFC 1006.
• Initial commissioning direct via Industrial Ethernet.
• Use of uncrossed connecting lines possible thanks to integrated auto
crossover function.
• Secure data communications via industrial-type device connection with IE
FC RJ45 plug 145/180 plug connector and additional strain relief thanks to
latching the connector to the housing.
Functions
The CP 343-1 BACnet handles all data traffic over Ethernet.
The module has its own processor. Layers 1 to 4 comply with international
standards.
Multi-protocol operation of transport protocols TCP/IP and UDP as well as BACnet
is possible.
The CP 343-1 BACnet has a preset, unique Ethernet address, allowing for
commissioning via network.
The CP 343-1 BACnet works in multi-protocol mode for the following
communications services:
BACnet (Building Automation Control Network) is a standardized layer 7-protocol
for building automation and control as per EN 16484, Part 5. It comprises:
− Standardized services processed autonomously by the CP.
− Standardized objects representing the user's view of automation and control.
The CP 343-1 is used with two market offering packages:
− DESIGO S7 Building Solution allows for using SIMATIC S7 within the DESIGO
system together with an S7-HVAC library following the DESIGO PX library.
Communications is via BACnet. Using an HVAC library allows for efficient
engineering of HVAC applications.
− DESIGO S7 Building Integration integrates existing SIMATIC S7 (software
without SBT HVAC LIB) in a DESIGO system over BACnet communications.
This allows for efficient integration. BACnet objects and their mapping to S7 data
is carried out in a mapping tool.
