Automation Description
Java-Applet

Entry -ID: 24207239
Automation task
In a plant, binary process variables of a SIMATIC S7-300, S7-400 or
S7-200 station shall be monitored and controlled via a standard web
browser as cost-efficiently as possible. The connection occurs via LAN or
WAN.
Automation solution
In the example on hand the individual buildings of an industrial site shall be
monitored and components such as lighting and air-condition be controlled.
It illustrates a simple option for visualizing and controlling binary process
variables of the SIMATIC S7 station on a web browser using configurable
Java applets. The Java applets have been developed with the JAVA S7Beans Library which is contained in the delivery scope of the IE CPs. The
source code of the Java applets is contained in this example and can be
modified by the user for expansions.
No previous programming knowledge is required. The process variables
are configured in a configuration file using a text editor. The Java applet
loads all information from the configuration file onto the industrial Ethernet
CP, which supports IT functions such as HTML process control, sending emails and the FTP protocol. It reads the process variables cyclically from
the controller and visualizes these on the web browser. A control applet
writes the process variables from the web browser into the SIMATIC S7
station.
The following figure illustrates the introduced solution:

Java applet “S7Table.jar” for group-oriented visualization of 48 bits
Overview
In the HTML-file “S7Table.html” the Java applet “S7Table.jar” for
visualization of 48 bits (6 bytes) is called. The 48 bits are bit by bit read
from a connected memory area of the CPU and displayed in the HTML-file
“BitPanel.html” in a group-oriented manner.
In this example the flag area is defined as memory area. Memory byte 0
(MB0) up to memory byte (MB5) inclusive are read out from the CPU.
The memory bytes are displayed line by line.
Bit 0 to Bit 7 of the memory bytes are displayed column by column as a
group, i.e. the individual bits of this memory byte have the same meaning
as for example Bit 1 = lighting.

In the configuration file the connected memory area is defined from which
the bits are read out byte by byte. The bytes are represented line by line in
the HTML page “S7Table.html”.
The number of bytes represented line by line in the HTML page is defined
via the S7-Anypointer S7-Adr (repFactor).
Prerequisite:
•
Parameter MAX_bytes ≥ repFactor
•
In the configuration file you need to define as many bytes as
represented line by line in the HTML-file.
Bit 0 to Bit 7 of the read out bytes represent one group respectively. In the
configuration file the 8 bit, i.e. 8 groups are defined. The meaning of the
grouped bits is displayed as column header in the HTML page
“S7Table.html”. Text and font for the states “0” and “1” of the bits of a group
can be configured as desired.
The status display displays the status of the CPU and the Industrial
Ethernet CP. Color, font and size of the text in the status display, as well as
the background color of the status display is defined by the user as desired

Java applet “Controlpanel.jar” for controlling binary states
Overview
In the HTML-file “Controlpanel.html” the Java applet “Controlpanel.jar” for
controlling binary states is called. 8 bits are represented in the HTML page.
Each bit is controlled via a separate button. The button realizes a switch
function or alternatively a push button function. The state of the bit is
visualized via the switch or push button position and via the color of the
button.

Above the switch it is displayed where the state of the bit is saved in the
CPU. In this example the states of the bits are storde in byte 1 of data block
2 (DB2) in the CPU. Hence they can be evaluated in the S7 user program.

The Java applet Controlpanel.jar is called using the <object></objects>
tags in the HTML-file. In HTML 4 this element was introduced which offers
a universal solution for the general integration of objects (applets, plug-ins,
media, images).

Preliminary remarks
To test the functionality of the tool / function block, we offer you a finished
software example with test code and test parameters as download. These
software examples support you in the first steps and tests.
The examples are always assigned to the components used in this
document and illustrate their interaction principles. However, they are not
real applications in the sense of technological problem solving with
definable properties.

Configuration of the SIMATIC Field PG
Setting the IP addresses
The IP address of the SIMATIC Field PG must lie in the same IP subnet as
the IP address of the S7-300, S7-400 and S7-200 station. In the properties
dialog of the network card of the SIMATIC Field PG you enter a fixed IP
address (see Table 5-2).
Setting PG/PC interface
The first download of the hardware configuration and the S7 program into
the controller is performed via MPI, since the IE CP has not yet been
configured with the IP address according to Table 5-2. Via Start Æ Control
Panel Æ Set PC/PG interface you adjust the S7ONLINE access point to the
MPI interface of your SIMATIC Field PG.
Alternatively you can also setup a connection with your S7-300 or S7-400
station via Industrial Ethernet. In this case at first you need to assign the
configured IP address to the IE CP. To do this use the Primary Setup Tool
(PST) or in the SIMATIC Manager the menu “Target system Æ Process
Ethernet stations”.
