| Packaging Line Integration.
SUMMARY:
Networked all OEM PLCs to establish supervisory control over
the entire packaging line.
DESCRIPTION:
A Profibus communication module was added to each OEM PLC
on the Filling and Packaging Line. Additional code was
developed for each of the PLC programs to pass faults, operator
setpoints, equipment status and interlocks to the HMI (Human
Machine Interface). An HMI was included to allow single
point access to all equipment parameters on the entire line. The
HMI was networked to the Plant Floor Server for Line Recipe
Management, downtime storage, event logging and fault data
collection.
The Line Operators would simply select a Product Recipe which
would download speeds, levels, limits, times and other essential
parameters to each piece of equipment on the line. This
reduced time to setup the line and improved accuracy for product. Additionally,
all equipment faults, events and status could be monitored and
collected for validation and archival records. |
