7. Analog I/O Buffering in Studio 5000 — Raw Data, Scaling, Engineering Units, and Signal Validation

In the previous article, we built a complete digital I/O architecture.

Digital signals are relatively simple:

0 = OFF
1 = ON

Analog signals are different.

An analog input may represent:

Tank level

Pressure

Temperature

Flow

Speed

Weight

pH

Conductivity

Valve position

Motor current
