The vector plot is a cross section of a four-electrode array. Two needles are at a high potential and two at low potential. Cosmos/EMS calculates field strength for a range of applied voltages.
The move to distributed networking for factory automation using Ethernet & TCP/IP is widely accepted, but there is also a move, perhaps not so obvious, to digitally networking servosystems using IEEE-1394.
