3M Scours for optimum capability

摘要

3M Espana makes Scotch-Brite scouring pads in its Madrid facility and to keep finished goods inventory to a minimum, plant personnel investigated ways to download more than 200 batch parameters from a Microsoft SQL database and use that information to configure the main production line's eight batch units. Using existing Allen-Bradley ControlLogix PLCs, plant personnel added an xCoupler enterprise transaction module from Online Development. The module installs in the ControlLogix rack and exchanges information between the database and batch unit devices connected to the PLC's backplane. A simple program was developed for the PLC that does not require any modifications when downloading recipes or configuring the units.
