Comparations are an important aid in the control processes whether digital or analog, that is how we see that any microprocessor from basic Z80 provides data comparisonroutines. In PLC are six data comparison routines that provide the possibility of determining whether a number is equal charged initially, smaller, greater than one number or loaded later.

Resumen

Las comparaciones y marcas son operaciones “if” que se pueden hacer con un temporizador.
Las comparaciones representan una ayuda importante en los procesos de controlya sean digitales o análogas, es así como vemos que cualquier microprocesador desde el Z80 básico ofrece rutinas de comparación de datos. En PLC hay seis rutinas de comparación de datos que ofrecen...
