How Do I Complete the Communications Connection?

Once you have installed STEP 7-Micro/WIN 32 software on your PC and set up
your PC for communications with the PC/PPI cable, you are ready to complete the
logical connection to the S7-200 CPU. (If you are using a programming device
(PG), STEP 7-Micro/WIN 32 is already installed.)
Follow the steps below to communicate with the S7-200 CPU:
1. In the STEP 7-Micro/WIN 32 screen, click the Communications icon, or select
View > Communications from the menu. The Communications Links dialog
box appears and shows that there are no CPUs connected.
2. Double click the refresh icon in the Communications Links dialog box.
STEP 7-Micro/WIN 32 checks for any S7-200 CPUs (stations) that are
connected, up to the highest station address in the specified communication
parameters. A CPU icon appears on the Communications Links dialog box for
each connected station. See Figure 3-4.
3. Double click the CPU station icon that you want to communicate with. You will
notice that the communication parameters on the Setup Communications
dialog box reflects the parameters for the selected station.
4. You are now communicating with the S7-200 CPU.
