| Control system upgrade for
palletizer in bottling plant.
SUMMARY:
Upgraded a palletizer PLC control system from one style PLC
to another.
DESCRIPTION:
The palletizer used an old style PLC for machine control and
an operator interface terminal (OIT) for pattern selection. The
program was converted to a new style PLC program, requiring restructuring
of the program layout and development of new file structure for
pattern storage. An interface to a case conveying system was
modified to allow multiple products to be palletized based on
the UPC code being scanned by a barcode reader. |
