The PLC was invented to solve the "relays bottleneck." Dick Morley, widely considered the father of the PLC, introduced the Modicon 084 in 1969 for General Motors. This innovation allowed factories to update their production lines by simply rewriting a software program rather than rebuilding physical hardware. 2. Core Architecture of a PLC System
Webb and Reis emphasize real-world utility by demonstrating how PLCs optimize efficiency, safety, and reliability across various manufacturing sectors. Automated Manufacturing and Assembly The PLC was invented to solve the "relays bottleneck
