Programmable Logic Controllers and the Broadcast Industry
With Phil Salkie
Programmable Logic Controllers (PLCs) are ruggedized industrial computing devices, currently used in every sector of manufacturing and industry. Designed for extremely high reliability, long uptimes, and easy serviceability, they are a natural fit for many niche requirements in broadcast operations such as tally, GPI routing, and transmission of digital control signals, and indeed have been used in broadcast service since the early 1980s.
We will demonstrate some PLC hardware, and discuss broadcast applications using standalone PLC systems, PLCs integrated with Operator Interface Terminals (OITs), and hybrid systems containing PLCs and general-purpose computers.
Tours of PCTV follow the presentation.
