SIMATIC S7-<strong>300</strong><br />
Communication<br />
CP 343-1 PN<br />
■ Overview<br />
• The CP 343-1 PN enables conn ection of SIMATIC S7-<strong>300</strong> to<br />
Industrial Ether<strong>net</strong><br />
- 10/100 Mbit/s full/half duplex connection with autosensing<br />
for automatic switching<br />
- Universal connection options for ITP, RJ45 and AUI<br />
- Adjustable Keep Alive function<br />
- TCP/UDP transport protocol<br />
• PROFINET communications standards: PROFINET, the Ether<strong>net</strong>-based<br />
communications standard, defines an engineering<br />
model for distributed automation solutions and a model for<br />
system-wide communication through PROFIBUS and Industrial<br />
Ether<strong>net</strong>. This standard is implemented by Siemens as<br />
Component based Automation.<br />
• Additional communication services:<br />
- PG/OP communication<br />
- S7 communication<br />
- S5-compatible communication<br />
• Multicast at UDP<br />
• Remote programming and commissioning through the<br />
<strong>net</strong>work<br />
