3.4 How Do I Go Online With the S7-200 CPU?
Once you have installed STEP 7-Micro/WIN 32 software on your PC and set up
communications with the PC/PPI cable, you are ready to go online with the S7-200
CPU. (If you are using a programming device, the STEP 7-Micro/WIN 32 is already
installed.)
Follow the steps below to go online with the S7-200 CPU:
