Ethernet simplifies monitoring and diagnostics
Internet permits remote access to high-speed press.
In terms of service headaches, the high-volume contract stamping facility had a conventional problem. A high-speed transfer press that moves sheet-metal parts through six sequential dies under one press ram, that had run reliably for months, suddenly experienced a series of mysterious "faults" that interrupted production. Visual inspection showed no obvious problem, such as an obstruction from stray scrap. What’s more, the programmable, servo-driven transfer system had a proven track record of efficiently handling sheet-metal parts.
What was different was the service call. Personnel at Atlas Technologies, a Fenton, Mich., pressroom automation specialist, diagnosed the problems without leaving the office. Through a modem and an Ethernet hub, controls engineer Scott Clement could explore the operational software and interrogate its logic.
