Will the 'PAC' supplant the 'PLC'?

Rockwell Automation has been using the term Programmable Automation Controller (PAC) for more than a year to describe a "new breed" that combines multiple platforms (sequential, motion, process control) with expanded information-handling. The PACs converge attributes of the programmable logic controller (PLC), the PC, and open-control platforms, says the supplier.

Users aren't just sharing information inside the corporation, according to Ken Deken, Rockwell VP. "We've also seen an unprecedented thirst for control system data, as users gather information for safety, finance, AQ, regulatory control, and other initiatives.

"To quench this thirst, what users need is a direct connection between the controller and the business system, providing information 'on-tap'."
