How to Test the Communications Network (GS 6.2)

1.From inside STEP 7-Micro/WIN 32, click on the Communications icon in the Navigation Bar or choose View>Communications from the menu.

2.From the right-hand pane of the Communications dialog box, click on the blue text that says "Double-Click to Refresh."

If you have successfully established communications between your personal computer and the devices on your network, a list of the devices (with their model types and station addresses) is displayed.

STEP 7-Micro/WIN 32 only communicates to one PLC at a time. A red box appears around the PLC that is currently in communication with STEP 7-Micro/WIN 32. You can double-click on a different PLC to change communications to that PLC.
