This first screen shot shows where the "memory words used" information is missing.....
This is because the Network Navigator window is closed. Once you open the Network Navigator window, the "memory words used" information will appear. The PLC memory usage can be found in the Logic Editor window. At the bottom of the screen there's a gray bar that lists the memory words used along with capacity. The first number is the memory words used and the number after the "/" indicates the total memory words available for the PLC.
