In order to trace control system problems to the core, the ability to read and interpret various resources, from facility-level diagrams to machine-level wiring layouts, is critical.

Converting different numbering systems is quite common in PLCs and structured text codes. Why? Because people read…

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.
