Automotive
Field:
One of the "big three" automotive manufacturers began having
communication problems with their Modbus Plus network. This
particular plant has a unique Modbus plus system in that it has
over six hundred nodes. This is one of the, if not the, largest
Modbus Plus network in the world. Also unique to the system, Bob
Culley assisted in its' initial design and installation while
working for Modicon.
The customer first called their local distributor and asked them
to call the factory to dispatch a field service engineer to
troubleshoot and repair their network. The distributor contacted
Delta Automation Inc. They responded with two experienced field
engineers and all of the proper and necessary test equipment to
the site immediately. After discussing the network problems with
the automotive engineers, Delta Automation, Inc. began its testing
and troubleshooting. The fault was located in an extremely short
time, and was determined to be a revision compatibility problem
with the Modbus Plus repeaters. The units were updated and the
system was online in minutes, after being down for two days. This
is just an example of how Delta Automation's experience and
superior knowledge was able to assist. Most certainly no other
third party service company would have been as swift to respond
and locate the fault.
