Exam 10: Introduction to Logic

The BAND function block can contain up to eight input points.

In reference to RSLogix ladder rungs, each rung is a(n) ____________________.

A normally closed instruction on a PLC ladder rung is the ____________________ of the input tag associated with the specific instruction.

The normally closed PLC ladder logic instruction is true any time the input tag bit is not a 1.

In PAC logic, the normally open instruction examines the bit to see whether it is closed. As a result, the instruction will be referred to as a(n) ____________________ instruction.

Rockwell Automation's ControlLogix, PLC-5, and SLC 500 families can be programmed in function block diagram language in addition to standard ladder logic.

A PAC relay ladder program uses an electrician's ladder schematic as a model. Briefly describe how the PAC relay ladder differs from a hardwired relay circuit.

RSLogix 5000 software provides the ability to interlace inputs and outputs on a ladder rung as long as the last instruction on a rung is some type of ____________________ instruction.

What is the most popular programming language for PACs?

Briefly describe function block programming.

In a two-input AND truth table, 0 AND 1 = 1.

Which familiar electrical circuit can also be referred to as the OR logic function?

Briefly distinguish between OR logic and exclusive OR logic for two inputs.

OR logic is similar to placement in series, as all series devices must pass continuity before the outcome is allowed to happen.

In a function block, the inputs points to the block are called ____________________.
