What is a logical control system and how does it differ from a sequencing system?
a) A logical control system is a switching system whose output is determined solely by the new input values, without memory or time-based characteristics. A sequencing system uses internal timers to define when to start output variable changes.
b) A logical control system is a system that uses internal timers to define when to start output variable changes. A sequencing system is a switching system whose output is determined solely by the new input values, without memory or time-based characteristics.
c) A logical control system is a system that uses internal timers to define when to start output variable changes. A sequencing system is a system that uses internal timers to define when to start input variable changes.

A alternativa correta é a letra A) Um sistema de controle lógico é um sistema de comutação cuja saída é determinada exclusivamente pelos novos valores de entrada, sem características de memória ou baseadas em tempo. Um sistema de sequenciamento usa temporizadores internos para definir quando iniciar as mudanças nas variáveis de saída. Enquanto um sistema de controle lógico é baseado em entradas e saídas, um sistema de sequenciamento é baseado em tempo e usa temporizadores internos para controlar a sequência de eventos.
