3. Verifying the Communications Parameters for STEP 7 Micro/WIN
The example project uses the default settings for STEP 7 Micro/WIN and the RS-232/PPI Multi-Master cable. To verify these settings:
3.1. Verify that the address of the PC/PPI cable in the Communications dialog box is set to 0.
3.2. Verify that the interface for the network parameter is set for PC/PPI cable (COM1).
3.3. Verify that the transmission rate is set to 9.6 kbps.
4. Establishing Communications with the S7-200
Use the Communications dialog box to connect with your S7-200 CPU:
4.1. Double-click the refresh icon in the Communications dialog box.
STEP 7 Micro/WIN searches for the S7-200 station and displays a CPU icon for the connected S7-200 station.
4.2. Select the S7-200 and click OK.
If STEP 7--Micro/WIN does not find your S7-200 CPU, check the settings for the communications parameters and repeat these steps.
After you have established communications with the S7-200, you are ready to create and download the example program.
