1.3 Communication services

CP 443-1 Advanced (GX30)

Manual, 03/2019, C79000-G8976-C256-05

●

Open communication services with the following functions:

– SEND/RECEIVE interface over ISO transport connections

– SEND/RECEIVE interface over TCP connections, ISO-on-TCP and UDP connections

With the SEND/RECEIVE interface via TCP connections, the CP supports the socket

interface to TCP/IP available on practically every end system.

UDP frame buffering on the CP can be disabled during configuration. When

necessary, this allows you to achieve a shorter reaction time between the arrival of a

UDP frame and its evaluation on the CPU.

– Multicast over UDP connection

The multicast mode is made possible by selecting a suitable IP address when

configuring connections.

– FETCH/WRITE services (server services; corresponding to S5 protocol) via ISO

transport connections, ISO-on-TCP connections and TCP connections;

Here, the SIMATIC S7400 with the CP is always the server (passive connection

establishment) while the read or write access (client function with active connection

establishment) is always initiated by a SIMATIC S5 or a device from another range /

PC.

– LOCK/UNLOCK with FETCH/WRITE services (CPU-dependent; see section

Requirements for use (Page 41))

●

Open TCP/IP communication

Open TCP/IP communication provides a program interface for the transfer of connection-

oriented and connectionless services. The establishment and termination of connections

is initiated here only via the "dynamic" program interface.

STEP 7 provides a UDT for the connection description as well as four FBs for data

exchange.

The CP supports communication via ISO-on-TCP connections for this interface.

●

SIMATIC Safety - Fail-safe communication

The CP supports fail-safe communication via S7 connections. A fail-safe connection can

run from the local CPU via the CP to the relevant communications partner, for example

another F-CPU or a fail-safe distributed I/O system.

You do not need to configure any special safety relevant properties for the CP.

●

IT functions

–

HTTP

– Web server: Monitoring devices and process data (HTML process control)

–

FTP

FTP functions (File Transfer Protocol) for file management and access to data blocks

in the CPU (client and server functions)

–

E-mail

Sending e-mail via SMTP or ESMTP. The CP supports t SMTP-Auth for authentication

on an email server and STARTTLS.
