Siemens SIMATIC S7-200 System Manual page 233

Configure STEP 7--Micro/WIN to use PROFIBUS protocol for a CP card. Select the DP or
Standard profile if there are only DP devices present on the network. Select the Universal
(DP/FMS) profile for all master devices if there are any non--DP devices on the network, such as
TD 200s. All masters on the network must be set up to use the same PROFIBUS profile (DP,
Standard or Universal) for the network to operate.
The PPI Multi-master cables will function on networks up to 187.5 kbaud only if all master devices
are using the Universal (DP/FMS) profile.
Sample Network Configurations Using Ethernet and/or Internet
Devices
In the configuration shown in Figure 7-19, an
Ethernet connection is used to allow
STEP 7--Micro/WIN to communicate with either of
the S7-200 CPUs which are using an Ethernet
(CP 243--1) module or an Internet (CP 243--1 IT)
module. The S7-200 CPUs can exchange data
through the Ethernet connection. A standard
browser program running on the PC with
STEP 7--Micro/WIN can be used to access the
home page of the Internet (CP 243--1 IT) module.
For Ethernet networks, you configure
STEP 7--Micro/WIN to use TCP/IP protocol.
Tip
In the Set PG/PC Interface dialog, there are at least two TCP/IP choices. The selection
TCP/IP --> NdisWanlp is not supported by the S7-200.
In the Set PG/PC Interface dialog box, the option(s) depend upon the type of Ethernet
-
interface provided in your PC. Choose the one that connects your computer to the Ethernet
network where the CP 243--1 or CP 243--1 IT module is connected.
On the Communications dialog, you must enter the Remote IP address(es) of each of the
-
Ethernet/Internet modules with which you wish to communicate.
