Q:
Is Reconfiguration Required When I Move The Wireless CNC Machines Around?

A:
No, as long as the relocated machine is in the same building and connecting to the same access point. There is some minimal software reconfiguration if the machine is relocated to a different building or access point. In large manufacturing plants we sometimes install multiple access points for better range, this is the same for manufacturing plants with multiple buildings.
The wireless connection moves with the machine.

Should you replace a machine you can simply move the wireless device to the new machine which will then show up on the wireless network...good stuff!
