For several decades, programmable logic controllers (PLCs) have dominated the automation world with reliable, discrete logic and straightforward analog I/O – and their firmly planted roots will continue to grow for the foreseeable future. However, as industrial machines increase in complexity and efficiency, programmable automation controller (PAC) technology provides a great complement to existing systems by adding the high-performance I/O and processing that traditional PLCs cannot offer. With easy methods for integrating PACs into existing PLC architectures, you now have several options for boosting your PLC-based automation systems. This white paper explores the top five technologies and discusses how users are implementing them today.
