Converting different numbering systems is quite common in PLCs and structured text codes. Why? Because people read decimals. Computers read binary. Processors read sets of bits. Not so simple.

A complete diagram for wiring nearly any kind of discrete I/O module, including digital, AC, or relay, including both sourcing and sinking varieties.
Controlling the startup of a motor not only reduces the wear on the motor, but eases the burden on the electrical supply, reducing infrastructure demands and the running cost of industrial loads.
