This protocol can be used, for example, for communication with following devices: - Since the S7 protocol is proprietary, there is lit-tle published information about attacks against it. An exception is the work of (Beresford, 2011). The author showed that the standard S7 protocol is not encrypted, or authenticated, it is susceptible to spoo ng, session hijacking, Denial of Service (DoS) attacks, and other at-tacks.

It is run between PLCs of the Siemens S7 family for PLC programming, data exchange, data accessing from SCADA systems and diagnostic purposes. The Siemens S7-200 has a limited variety of functions, but it certainly also has a lot of advantages. With this article, you will be ready to start configuring and programming the Siemens S7-200 PLC. As you may know, the PLC product line from Siemens is named S7 or Step 7 PLCs. The smallest PLC model is the Siemens S7-200 PLC. The S7 Comm Plus protocol is a new version of the original S7 Comm protocol. While a S7 Comm packet is identified, by the magic byte 0x32, the S7 Comm Plus packet uses the magic byte 0x72.The End of a packet is indicated by a frame end sequence of 6 bytes: 00 00 72 01 00 00 Automatic protocol- and baud rate detection (depends on the used product from 9K6 to 12M) Connects only to the bus when it is requested by PG Firmwareupdate via internet for free PPI - adapter for S7 - 200 MPI/Profibus - adapter for S7 - 300 + 400 CE/EMC compliant construction The S7-TCP/IP protocol is also known as "RFC1006" or "ISO on top of TCP".The PLCs usually communicate by this protocol via PROFINET connector (connector for Ethernet network).. This protocol can be used, for example, for communication with following devices: - Siemens Simatic: SS7 HACK. With access to SS7 and a victim’s phone number, an attacker can listen to a conversation, pinpoint a person’s location, intercept messages to gain access to mobile banking services, send a USSD (Unstructured Supplementary Service Data) command to a billable number, and conduct other attacks.

The S7Ethernet Server provides access to a Siemens PLC through an off-the-shelf standard Ethernet network interface card in the computer and uses the “ISO over TCP” communication protocol, implemented by Description This indicates detection of the S7 protocol. S7 is a proprietary communication protocol by Siemens. It is run between PLCs of the Siemens S7 family for PLC programming, data exchange, data accessing from SCADA systems and diagnostic purposes.

This Protocol is not freely available and only runs with drivers just like the SIMATIC NET Software. If you would like to have TCP/IP or UDP/IP you may surely use the standard socket interface of your OS. S7 protocol settings: Home Back Next: In Siemens S7 controllers and compatible the connection parameter details will be defined automatically.
