Terminology
Programmable : Its behavior is able to be modified by using programming language
Logic : Structured, step by step, “make sense”
Controller : Device used to manage another device
Discrete : a boolean function (true/false) OR (1/0) OR (on/off)
LAD/LDR/ladder : a programming language using “Electrical Circuit” logic
STL/Statement List : a programming language using “English structured” logic
INPUT : Incoming signal
Output : Outcome / result signal

Introduction to PLC
A PLC is simply a block / device use to MANIPULATE input signal by using certain
RULES
The manipulation process called Control
The rules called Program
