Using the information from your previous post.
Are you asking if the ML1000 along with the ENI can be connected wirelessly?
The answer is yes. If the place you are installing the ML1000 has an existing wireless network then you need a wireless bridge to connect the ENI to. I am doing this with a ML1000 over 802.11 G. I am able to upload/download/go online/program over this connection. The gotcha doing it this way is network latency. I had to adjust the OPC server scan rate to 500ms to avoid issues with stale data.
