SOFTWARE COMPONENTS

1. Ladder Diagram Language – a symbolic instruction type language

2. Boolean Language- Basic level language that composed of three (3) Boolean logic operation: AND, OR, NOT

4. English Statement Language – considered derivative of computer language such as BASIC.

3. Functional Blocks Language – high level instructions that permit the user to program more complex functions using the ladder diagram format
