Basic Configurations

After starting the Internet wizard, you will see the configuration wizards. All specifi-
cations which you enter here will be stored on the S7-200 CPU when loaded to the
S7-200 system.
The introductory screen of the configuration wizard gives you general information.
After reading this, click "Next>" to continue with the wizard.
Specification of the Position of the CP 243-1 IT in the S7-200 system
The position of the CP 243-1 IT in the S7-200 system must be specified in the sec-
ond screen.
This position can be manually specified or the wizard can look for a CP 243-1 IT in
your S7-200 system. If it finds a CP 243-1 IT, its position in the S7-200 system is
automatically indicated. Double-clicking the indicated CP 243-1 IT accepts its posi-
tion in the configuration.
Specifying TCP/IP address parameters and transmission type
The next screen is used to specify the TCP/IP address parameters and the type of
transmission to be used.
There are two ways to enter the TCP/IP address parameters.
1. Enter these parameters manually in the applicable input boxes.
2. Activate the access to a BOOTP server. In this case, the CP 243-1 IT obtains
the TCP/IP address parameters from a BOOTP server during startup. If the CP
243-1 IT is unable to find a BOOTP server in its TCP/IP network, it performs a
reset, restarts and tries again to establish contact with a BOOTP server. It con-
tinues to do this until it finds a BOOTP server from which it can obtain TCP/IP
address parameters.
Specifying the control byte and the number of S7 connections
Afterwards, use the next screen to enter the address of those bytes in the address
area of your S7-200 system via which the CP 243-1 IT can be accessed from the
S7-200 CPU. This address depends on the position of the CP 243-1 IT in your S7-
200 system and the number of outputs in your S7-200 system. If you "told" the
Internet wizard at the beginning of the configuration to determine the position of the
CP 243-1 IT in your S7-200 system, the wizard will give you the address here.
You can always use STEP 7 Micro/WIN 32 to determine the address areas occu-
pied by the modules in your S7-200 system by activating the entry "Information..."
in the menu "PLC". You will also find the address under which your CP 243-1 IT
can be accessed in your S7-200 system.
