IIoT Bridges

The newest IIoT-capable
I/O and controllers make
it practical to connect,
monitor, and control
standalone production
and facilities equipment.

PLANT FLOOR AND facility data comes
in many varieties and serves different
purposes. It's obtained from plant sensors
and smart systems located at what is often
termed the operational "edge" of network
connectivity.
Sometimes end users simply want to
monitor a key performance indicator (KPI)
such as a temperature or production rate.
Other times they may need to be notified
if a subsystem is in alarm. More advanced
applications require computations to, for
example:
 integrate and coordinate with a higherlevel manufacturing execution system (MES)

 determine overall equipment effectiveness
(OEE)
 support maintenance and asset-management systems.
Imagine how much money could be saved
if an early warning of high temperature for
a refrigeration system notified the team in
time to call in service before product was
wasted. How much safer and less expensive
would it be for a facility to monitor sump
pump status and levels without requiring
operators to make rounds? Connecting with
operational data is fundamental for OEE
and MES initiatives, but how should this
functionality be added?

MAKING THE CONNECTION
In many facilities, processing and packaging
lines are assembled by linking a variety of
equipment, each with its own programmable logic controller (PLC) automation and
upstream/downstream interlocks. Newer
assets may be available with a wired Ethernet or wi-fi connection, but most in-place
processes involve older equipment as well.
Users can connect to these systems for
configuration and monitoring, but it may
not be as simple as they'd like. Technical
complexity arises due to numerous communication protocols, tagging methods, and
data-processing considerations. For legacy
