OVERVIEW
Linked by Ethernet, Network Instrumentation Module provide dis-
tributed instrumentation and high-speed communication with less
wiring and less engineering work. The modules also create value for
customers by offering reduced environmental impact, superior qual-
ity, and higher productivity. The NX-SVG Smart Device Gateway
transfers data between a host device such as a PLC and slave devices
such as Network Instrumentation Modules.
