Deck 1: Introduction to Control Logix Hardware

Question 1

The backplane of the ControlLogix chassis is a ControlNet network called ____________________.

Answer 1

ControlBus

Question 2

Briefly distinguish between the types of volatile memory backup in series 6 series A controllers, series 6 series B controllers, and series 7 controllers.

Answer 2

Series 6 series A controllers use the controller battery 100 percent of the time to maintain power to controller volatile memory.
Series 6 series B controllers have a battery that is used only to transfer the project to onboard nonvolatile memory when power is lost.
Series 7 controllers have a capacitor module (referred to as an ESM) that replaces the battery function.

Question 3

Moving data from one network to a different network is called ____________________.

Answer 3

bridging

Question 4

List three new features of ControlLogix series 7 controllers.

Question 5

What distinguishes the ControlLogix modular PAC from traditional PLCs?

Question 6

Analog input and output signal connections to an analog module are referred to as ____________________.

Question 7

List three considerations when selecting a ControlLogix controller.

Question 8

The 1769-L23 CompactLogix is a fixed or packaged controller where the controller, power supply, and I/O are contained in a single unit.

Question 9

The far left slot of a traditional PLC chassis or a ControlLogix chassis is known as slot one.

Question 10

____________________ is the most popular network today because of its fast speed and readily available off-the-shelf components.

Question 11

What is a major advantage of DeviceNet, an open network intended to link low-level devices?

Question 12

The two most common modes of a controller are Run and Test.

Question 13

ControlNet is an open-control level network used for real-time data transfer of time-critical and non-time critical data among controllers or I/O on the same link.

Question 14

In the ControlLogix operating cycle, the ____________________ specifies the rate at which the module being configured sends or multicasts its data.
