Micro Automation Set 15

V1.1 (Issue 11/2003)

Preamble

Micro Automation Sets are fully functional and tested automation configurations based

on A&D standard products for simple, fast and inexpensive automation tasks for small-

scale automation. Each of these Micro Automation Sets covers a frequently used

subtask of a typical customer automation task in the low-end range.

The sets help the customer answer the following questions for these subtasks: “Which

products do I need?” and “How do the products work together?”

However, depending on the requirements of the system, a variety of other

components (e.g., other CPUs, power supplies, etc.) can be used to implement the

functionality on which this set is based. See respective SIEMENS A&D catalogs for

these components.

Simple Process Communication based on Web Technology: Web-Browser, E-mail and FTP

(with S7-200 and CP 243-1 IT)

Method of Function

In this configuration, an S7-222 CPU with Industrial Ethernet

communication processor CP 243-1 IT is directly connected with a network.

Optionally, the S7-222 CPU with CP 243-1 IT can also be connected with a

network or e.g. a mobile service via router 1 .

Note

Set 14 describes, how in one system several CPUs can exchange data via a TP40

Switch.

The communication is based on the TCP/IP protocol. As opposed to the

standard CP 243-1, the CPU can via CP 243-1 IT communicate in three

different ways (on top of normal S7-communication):

• HTTP communication to the Web-Browser

The HTTP-Server answers questions from HTTP-Clients (e.g.

Standard-Web-Browser). It is possible to simultaneously establish up to

4 connections from different clients to the server.

Suitable parameterization/programming (Java Applets 2 ) enables filing an

HMI in the IT CP by means of HTML pages, which can be displayed by

means of any standard web-browser (password protected).

• E-Mail communication (not realized in the test/configuration code)

For the IT CP up to 32 E-mails can be configured, which are sent event

controlled from the CPU to an E-mail server. The E-mail server in return

sends the e-mails to the receiver specified in the configuration.

In the message text, the E-mails may contain configured process values.

1 A router has a bridging function between different networks.

2 Standard S7-Applets (parameterizing) or user generated Java applets using S7-beans

(programming)

Simple Process Communication based on Web Technology: Web-Browser, E-mail and FTP

(with S7-200 and CP 243-1 IT)

• FTP communication (not realized in the test/configuration code)

Via the IT CP, the CPU can send data blocks (or parts of it) to other

computers (e.g. PCs) as files, or read and delete files of other

computers. Communication via FTP is possible with by means of almost

any operating systems (Unix, Windows, Linux).

Configuration/Test Code

Functionality of Configuration/Test Code

Using wiring and configuration described in the document the web-site

displayed below communicates with the S7-200 CPU.

Note

Configuration setup and generating the configuration/parameterization are merely

for function testing (there is no technological task involved!).
