Siemens TCP/IP Ethernet Driver Help 13 How To Configure S7-200 Connections in Micro/WIN Configured connections are accomplished through the Ethernet wizard in Micro/WIN. The following instructions illustrate each step in the Ethernet wizard and also describe any precautions that should be taken. Follow these instructions closely to use configured connections with the Siemens TCP/IP Ethernet Driver correctly. Note: The Micro/WIN software may require an upgrade before the Ethernet wizard is made available.
Siemens TCP/IP Ethernet Driver Help 14 Note: The program must be compiled before the Ethernet wizard can execute. Correct any errors in the program before continuing. Step 2: Setting CP243-1 Module Position 1. Click Read Modules. Note: While it is recommended that the Read Modules function be used, this does require that the PLC be connected to the PC either serially or by Ethernet. In either case, the communications parameters for Micro/WIN must be properly set for the Read Modules operation to occur.
Siemens TCP/IP Ethernet Driver Help 15 Step 3: Assigning Module Address 1. Enter the IP Address, Subnet Mask and Gateway Address if applicable. Alternatively, enable BOOTP if applicable. 2. Select Auto Detect Communications to allow the module to automatically select either 10BaseT or 100BaseT. In rare cases where there may be a cable issue that does not allow the module to operate properly at 100BaseT, force the module to use 10BaseT. This will increase the modules' tolerance to a bad Ethernet line. 3.
Siemens TCP/IP Ethernet Driver Help 16 Note: The number of connections selected determines how many simultaneous connections the PLC can support. When intending to have only one OPC server talking to the PLC, set up only one connection. This will ensure the best performance for the OPC server. When intending to have more than one active connection to the PLC, use multiple connections. Keep in mind, however, that the performance of the module will be impacted as each connection is used. 2.
Siemens TCP/IP Ethernet Driver Help 17 There are two types of connections, client and server. In a client connection, the device is a client and makes request with servers (other devices). In a server connection, the device is a server and handles requests from clients (such as the OPC server and other devices). The latter is required for communications with the Siemens TCP/IP Ethernet Driver. 1. Select This is a Server Connection. 2.

Note: Use caution when modifying Word, Short, DWord, and Long type as each address starts at a byte offset within the device. Therefore, Words MW0 and MW1 overlap at byte 1. Writing to MW0 will also modify the value held in MW1. Similarly, DWord, and Long types can also overlap. It is recommended that these memory types be used so that overlapping does not occur.
