Setting the Baud Rate and Network Address for STEP 7- -Micro/WIN
You must configure the baud rate and network address for STEP 7--Micro/WIN. The baud rate
must be the same as the other devices on the network, and the network address must be unique.
Typically, you do not change the network address (0) for STEP 7--Micro/WIN. If your network
includes another programming package, you might need to change the network address for
STEP 7--Micro/WIN.
As shown in Figure 7-3, configuring the baud rate
and network address for STEP 7--Micro/WIN is
simple. After you click the Communications icon in
the Navigation bar, you perform the following steps:
1. Double-click the icon in the Communications
Setup window.
2. Click the Properties button on the Set PG/PC
Interface dialog box.
3. Select the network address for
STEP 7--Micro/WIN.
4. Select the baud rate for STEP 7--Micro/WIN.
Setting the Baud Rate and Network Address for the S7-200
You must also configure the baud rate and network address for the S7-200. The system block of
the S7-200 stores the baud rate and network address. After you select the parameters for the
S7-200, you must download the system block to the S7-200.
The default baud rate for each S7-200 port is
9.6 kbaud, and the default network address is 2.
As shown in Figure 7-4, use STEP 7--Micro/WIN to
set the baud rate and network address for the
S7-200. After you select the System Block icon in
the Navigation bar or select the View > Component
> System Block menu command, you perform the
following steps:
1. Select the network address for the S7-200.
2. Select the baud rate for the S7-200.
3. 3. Download the system block to the S7-200. Download the system block to the S7-200.
Tip
Selection of all baud rate options is permitted. STEP 7--Micro/WIN validates this selection
during the download of the System Block. Baud rate selections that would prevent
STEP 7--Micro/WIN from communicating with the S7-200 are prevented from being downloaded.
