Overview
- The connection of SIMATIC S7-300/SINUMERIK 840D powerline to Industrial Ethernet
- 2 x RJ45 interface for 10/100 Mbps full/half-duplex connection with autosensing/autonegotiation and autocrossover function
- Integrated 2-port real-time switch ERTEC
- Multi-protocol operation with ISO, TCP, UDP transport protocol and PROFINET IO
- Adjustable keep-alive function
- Communications services:
- Open communication (ISO, TCP/IP, and UDP)
- PROFINET IO controller or PROFINET IO device
- PG/OP communication: Cross-network by means of S7 routing
- S7 communication (client, server, multiplexing)
- Media redundancy (MRP);
within an Ethernet network with ring topology, the CP supports the media redundancy procedure MRP (V2.2 or higher). - Multicast for UDP
- IP address assignment via DHCP, simple PC tool or via the user program (e.g. HMI)
- Access protection via configurable access list
- Remote programming and commissioning via Industrial Ethernet
- Configuration with STEP 7
- Automatic setting of CPU clock setting over Ethernet with NTP or SIMATIC procedure
- Web diagnostics
- Integration in network management systems via SNMP (MIB2 diagnostics information)
- Diagnostics possibilities in STEP 7 and via web browser
Benefits
- High level of plant availability due to support of media redundancy (MRP)
- Optimum support of maintenance through
- Web-based diagnostics
- Remote programming via WAN or a telephone network (ISDN)
- Monitoring by means of IT network management tools (SNMP)
- Module replacement without programming device thanks to saving of the configuration data on the CPU
- Securing the system against unauthorized access by means of device-related IP address lists
- The capability of later connecting existing SIMATIC S7 systems to Industrial Ethernet using the CP 343-1 ensures investment protection
Application
The CP 343-1 is used for connecting the SIMATIC S7-300/SINUMERIK 840D powerline to Industrial Ethernet networks. With its own processor, it relieves the CPU of communications tasks and facilitates additional connections.
The CP 343-1 permits communication of the S7-300 with:
- PGs/PCs
- Master computers
- HMI devices
- SIMATIC S7/C7 systems
- PROFINET IO devices
Design
The CP 343-1 has all the advantages of the SIMATIC S7-300 design:
- Compact design;
on the front, the rugged plastic housing features:- Two RJ45 sockets for connection to Industrial Ethernet with automatic sensing of the data transmission rate by means of Autosensing/Autonegotiation;
the RJ45 sockets are industrially compatible and designed with additional holding collars for connecting to the IE FC RJ45 Plug 145/180 - 2-pole plug-in terminal strip for connection of the 24 V DC external supply voltage
- 8 LEDs for indication of the operating and communication status (diagnostics for each switch port)
- Two RJ45 sockets for connection to Industrial Ethernet with automatic sensing of the data transmission rate by means of Autosensing/Autonegotiation;
- Easy installation;
the CP 343-1 is mounted on the S7-300 rail and connected through the bus connector with the neighboring modules. No slot rules apply. - Fan-free operation;
A back-up battery is not required. - Using the IM 360/361, the CP 343-1 can also be operated in the expansion rack (ER)
- Modules can be replaced without the need for a programming device
Function
- PROFINET interface with two RJ45 connectors with 10/100 Mbit/s full/half duplex with autosensing and autocrossover functionality via integrated 2-port switch
- Communication services via interface:
- Open communication (TCP/IP, UDP, ISO): Multicast for UDP
- PG/OP communication: inter-network with S7 routing
- S7 communication (client, server, multiplexing)
- PROFINET IO Controller or IO Device
- Media redundancy (MRP):
- Within an Ethernet network with ring topology, the CP supports the media redundancy procedure MRP
- Diagnostics and network management:
- Extensive diagnostic functions for all modules in the rack
- Integration into network management systems through the support of SNMP V1
- Security mechanisms:
- Access protection by means of configurable IP access list
- Configuring of all functions with STEP 7, V5.4 or higher, or STEP 7 Professional V11 (TIA Portal) or higher
- Module replacement without programming device thanks to saving of the configuration data on the CPU
