Communication via Ethernet CPs in S7 Stations

SS7 communication

S7 communication forms a simple and efficient interface between SIMATIC S7 stations and PGs/PCs using communication function blocks.

SS5-compatible communication with SEND/RECEIVE interface

Depending on the CP type, the SEND/RECEIVE interface allows program-controlled communication on a configured connection from a SIMATIC S7 PLC to another SIMATIC S7 PLC, to a SIMATIC S5 PLC, to PCs/PGs, and to any other station.

Depending on the CP type, the following communications services are available on the SEND/RECEIVE interface:

ISO Transport

optimized for top performance at the self-contained manufacturing level

TCP/IP for internetwork communication with ISO-on-TCP connections (RFC 1006), TCP connections and UDP datagram service (including broadcast / multicast).

Sending E-mail

The controller is capable of sending messages triggered by process events (refer to the IT-CP manual for details /5/).

SS5-compatible communication with FETCH/WRITE services (server)

The FETCH/WRITE services (server) allow direct access to the system memory areas on the SIMATIC S7 CPU from SIMATIC S5, SIMATIC PC stations, or from devices of other ranges.

Depending on the CP type, the following communications services are available for FETCH/WRITE access:

ISO Transport

optimized for top performance at the self-contained manufacturing level

TCP/IP for internetwork communication with ISO-on-TCP connections (RFC 1006), TCP connections.

SPROFInet communication

PROFInet is a standard of the PROFIBUS Users organization defining a heterogeneous communications and engineering model.

An S7-300 station equipped with a CP capable of PROFInet can be interconnected as a PROFInet component in SIMATIC iMap.

TCP connections are used for the PROFInet communication. For more detailed information on PROFInet, refer to /23/.

SHTML process control

With an IT-CP, use the supplied functions and HTML pages to query important system data using a Web browser (you should also refer to the instructions on the IT-CP /5/).
