CC-Link Improves Printing Press Control

CC-Link provides the "open" network backbone for the control of 32 Tensor printing press units at Engle Printing in Lancaster, PA. It is also the network controlling 2 four-color presses at Press Enterprise in Bloomsburg, PA. These systems were designed and installed by Computer Integrated Automation, Inc. of Carol Stream, Illinois. Computer Integrated Automation (CIA) is an authorized Mitsubishi Electric system integrator. CC-Link is used for remote interface, integrating third party equipment devices, data collection, information handling, and the exchange of control signals between PLC’s and the presses. CIA has used CC-Link in 8 other printing installations in addition to those described here.

Substantial cost savings are realized through the use of CC-Link networking. The amount of wiring in a 24 unit non-networked press is typically 150,000 feet. This included hundreds of digital and analog I/O that would need to be individually wired back to a central controller. The use of CC-Link has drastically reduced the amount of wiring to approximately 10,000 feet for a dramatic savings of approximately 140,000 feet of wire. Not only is the cost of the wire itself reduced but the labor to install, route and terminate this 140,000 feet of wire is saved.
