TCP/IP Protocol
The S7-200 can support TCP/IP Ethernet communication through the use of an Ethernet (CP 243--1) orInternet (CP 243--1 IT) expansion module. Table 7-4 shows the baud rate and number of connections supported by these modules.
Table 7-4 Number of Connections for the Ethernet (CP 243--1) and the Internet (CP 243--1 IT) Modules Module Ethernet (CP 243--1) Module Internet (CP 243--1 IT) Module 10 to 100 Mbaud Baud Rate Connections 8 general purpose connections 1 STEP 7--Micro/WIN connection Refer to the CP 243--1 Communications Processor for Industrial Ethernet Manual or the CP 243--1 IT Communications Processor for Industrial Ethernet and Information Technology Manual for additional information.
