Triangle Packaging Machinery Company, located in Chicago, Illinois, wanted to provide a control solution for one of their
applications that was non-proprietary, enabling packaging professionals easy access to update applications when needed. Triangle required the flexibility of a Programmable Logic Controller and the processing speed of an industrial computer to have optimal performance in their Multihead Weigher / Vertical Form Fill Seal Bag Machine (VFFS) application. Triangle found a solution in the Rockwell Automation ControlLogix PLC with ProSoft Technology's PC-56 in rack PC.
“The PC56s high speed communications across the ControlLogix backplane permits the tightly integrated PC-based application Triangle was looking for," said Ken Majerus. “The PC56 is the ideal solution for this type of analytical and data centric applications."
The industrialized PC-56 inRAx computer delivers the processing power required to control the speed of the Combinational Weigher. The PC-56 connects directly to the backplane of the ControlLogix PLC, which gives the application an extremely high data exchange rate between the PC-56 and the ControlLogix PLC. The speed of the calculations for the Combinational Weigher is pivotal to the speed and efficiency of the integrated Scale/VFFS application, as some of the larger applications have up to 18 buckets per Multihead Weigher system.
