MARIETTA, GA - 06/2010
 In
Wells, Maine, USA, Spencer Press produces a variety of products
including catalogs, press-pasted booklets, free-standing inserts and
self-mailers. The company was acquired by RR Donnelley in 2005.
Due to continued issues with
maintaining the TI 560/565-based control system on its M1000 press,
the company in 2007 contacted Goss International, who acquired
Heidelberg's web press and high-volume post press business in August
of 2004. Goss, in turn, contacted CTI regarding the use of our new
2500 Series processor in replacement of the 565.
Existing Control System Design
The existing control system used on the M1000 press employed a
TI560/565 processor with remote I/O connection over coax to thirteen
Series 500 I/O bases. Spencer felt that they could continue to
maintain the Series 500 I/O systems for a while longer, but wanted
an immediate replacement of the controller and upgrade of the
programming software to PLC Workshop.
Proposed Control System Upgrade
Working together, CTI and Goss application engineers specified a CTI 2500-C300
processor, four slot base, CTI 2512 power supply, and 505-6860 RF I/O channel
converter to drive the coaxial I/O network. Because the 2500 Series™ system supports
the same instruction set as the one used in the 560/565, no changes in the program
logic were required.
 Upgrade Result
The system was initially installed in September 2007. The only
program change required was re-addressing of some I/O due to
combining the two previous I/O networks into a single network.
After resolving some issues over coax I/O reliability and Series
500 I/O login, the press has been running without incident. RR
Donnelley is currently considering the next upgrade phase which
includes changeout of the Series 500 I/O bases for new CTI 2500
Series™ systems.
