Lab 1: Creating a New Project (40 Minutes) About This Lab In this lab, we will introduce you to the Logix product family. In this lab you will:
Have an overview of ControlLogix, FlexLogix, and CompactLogix
Create a new project
Write ladder logic
Use symbolic tag names
Use the tag monitor/editor
Configure I/O modules
Alias the module tags to the tags you created in your ladder logic During Lab 1 we will not be concerned with what Logix controller equipment is in front of you. All the concepts in Lab 1 apply across all Logix platforms.
Follow the steps below to complete Lab 1.
About ControlLogix, FlexLogix, and CompactLogix Controllers ControlLogix The ControlLogix platform provides a modular control platform suited for sequential, process, drive, or motion control applications - in any combination. With this platform, you can mix multiple processors, networks, and I/O without restrictions. And as your system grows, you can use either a ControlNet or EtherNet I/P network to distribute control to additional chassis and/or other Logix platforms. A ControlLogix system can consist of anything from a stand-alone controller and I/O modules in a single chassis, to a highly distributed system consisting of multiple chassis and networks working together. ControlLogix controllers will fit your applications if they:
Require a high performance control solution
Demand the integration of multiple control disciplines (e.g., high speed packaging machines integrating sequential and motion control, or web handling applications integrating sequential and drive control)
Combine batch and process control, but seek a flexible choice of visualization software
Require a plant-wide control solution, from incoming materials to outbound shipping
Expand an existing investment in a PLC-5 or SLC 500 controller-based system
Introduction to Logix Hands-On Lab 4/6/2004
Page 11 of 93
FlexLogix The FlexLogix platform combines the high performance Logix control engine with the popular distributed FLEX I/O to provide a cost-effective distributed controller. The FlexLogix system is built on these components:
FLEX I/O modules which provide a compact, DIN-rail mounted I/O system. Through two local Flex rails. This gives you up to 16 local I/O modules.
Two 1788 communication daughter cards which provide communication over ControlNet, EtherNet I/P or DeviceNet networks.
A simple FlexLogix system can consist of a single, stand-alone assembly with one controller and as many as eight I/O modules per rail or you can use multiple controllers across networks and distribute multiple I/O platforms over multiple I/O links. FlexLogix controllers will fit your applications if:
You are already using FLEX I/O and are looking for a simple way to add control to your distributed architecture
You are currently using a centralized control architecture to control multiple stations in a process
CompactLogix The combination of features, scalability, and the small size of the CompactLogix platform provide a powerful alternative for machine-level control, material handling, data acquisition, and distributed control. CompactLogix combines the high performance Logix control engine with the cost-effective rackless 1769 I/O platform and EtherNet and DeviceNet connectivity. CompactLogix will fit your applications if:
You are an existing Logix customer with lower-end, lower-cost control applications.
You are a new customer who wishes to apply Logix technology, but at a lower initial investment.
You are an existing PLC and/or SLC customer who wishes to convert to Logix technology.
You perform SCADA/RTU applications within a range of industries (e.g., petrochemical, wastewater, etc.)

The Controller Organizer appears on the left side of the RSLogix5000 window, with a folder called Controller Controller1. You have now created your first controller project. At this time, there is no I/O, no tag database, and no logic associated with the controller.
✒FYI The Controller Organizer is a graphical representation of the contents of your controller file. This display consists of a tree of folders and files that contain all of the information about the programs and data in the current controller file. The default main folders in this tree are:
Controller File Name
Tasks
Motion Groups
Trends
Data Types
I/O Configuration
In front of each folder, there is a square containing a + sign or a - sign. The + sign indicates that the folder is closed. Click on it to expand the tree display and display the files in the folder. The - sign indicates that the folder is already open and its contents are visible.

Creating Tags for the Ladder Code In this section of the lab you will create the tags needed for the program. In traditional PLCs, a physical memory address identifies each item of data, for example N7:0. In Logix controllers, there is no fixed numeric format. We use tags. You will continue to use the project already opened.
✒What is a tag and why are they better? A tag is a text-based name for an area of memory. By using a text-based system you can use the name of the tag to document your ladder code and organize your data to mirror your machinery. For example you could create a tag named North_Tank_Pressure. This helps to speed code generation and debugging. All tag names are stored in the controller. We will create 3 tags for the program: Motor_Start, Motor_Stop, and Motor_Run. 1. First you will create the tag Motor_Start. Right click on the ? of the XIC instruction and select New Tag.
Introduction to Logix Hands-On Lab 4/6/2004
Page 23 of 93
2. The New Tag window will appear.
✒Creating a tag When you create a tag there are several attributes for a tag. The main attributes we are interested in for this lab are as follows: Tag Type: Defines how the tag operates within the project. Base: Stores a value or values for use by logic within a project Alias: A tag that represents another tag Produced: Send data to another controller Consumed: Receive data from another controller Data Type: Defines the type of data that the tag stores. For example Boolean, Integer, Real, String, etc. Scope: Defines how the data is accessed in the project. Is it either controller scoped, global data accessible throughout the controller or program scoped, data accessible for a specific program.

Drag the tag Motor_Run tag over to the XIC instruction until a green dot appears next to the ?. Then release the mouse button.
Introduction to Logix Hands-On Lab 4/6/2004
Page 28 of 93
19. Your rung should now appear as shown below.
20. Notice the ‘e’s next to rung zero. These indicate that the rung is in edit mode. Click on the (End) rung. The ‘e’s are now gone. RSLogix 5000 software verifies each rung automatically when you click the mouse off of it. This makes programming easier. 21. Your rung should now appear as shown below.
22. Save the program by clicking on the Save icon
on the toolbar.
The tag database of Logix versus a traditional PLC’s fixed memory addresses help you create self-documenting code. This means you do not have to use address descriptions or symbols to make code easy to read.
Introduction to Logix Hands-On Lab 4/6/2004
Page 29 of 93
Monitoring/Editing Tags We will now look at the Tag Monitor/Editor in RSLogix 5000. We will also discuss the concept of Controller versus Program scoped tags. You will continue to use the project already opened. 1. From the Controller Organizer double click on Controller Tags.
2. The tag Monitor/Editor window appears. You notice in the lower left corner of the window two tabs labeled Monitor Tags and Edit Tags as shown below.
✒FYI Monitor Tags and Edit Tags Tabs When the ‘Monitor Tags’ tab is selected the actual value(s) for the tags will be shown. For example, if you were to view an input button the software would show the button tag actively energized or de-energized. When the ‘Edit Tags’ tab is selected, NEW tags may be created, and existing tag properties may be modified. If you are having difficulty creating or modifying tag parameters verify that the ‘Edit Tags’ tab is selected. 3. You notice first that there are no tags present, but you remember just creating 3 tags.
Introduction to Logix Hands-On Lab 4/6/2004
Page 30 of 93
4. You now notice a field in the upper left corner of the Tag Editor window labeled Scope. You remember from earlier in the lab that we talked briefly about Controller and Program scoped tags. Currently the selection is Controller1(controller).
5. When we created the tags earlier we created them in the Program Scope.
✒FYI Data Scoping When you create a tag, you define it either as a controller tag (global data) or a program tag for a specific program (local data).
Data at the program scope is isolated from other programs. Routines cannot access data that is at the program scope of another program. Thus you can re-use the tag name of a program-scoped tag in multiple programs.
Introduction to Logix Hands-On Lab 4/6/2004
Page 31 of 93
6. Click on the down arrow for the Scope selection box. 7. Select MainProgram.
8. The Tag Editor now has switched views to the program level and you see the tags you created earlier.
9. Save the program by clicking on the Save icon
on the toolbar.
Configuring I/O We will now look at configuring I/O for our project. To communicate with I/O modules you must add modules to the I/O Configuration folder. During this off-line lab we will only show adding 1756 I/O. Follow these steps no matter what controller is at your lab station. The procedure to add Flex I/O and Compact I/O is the same. The 1756 I/O platform is the premier I/O platform and we will show you some of its advanced features such as:
No load detection
Open wire detection
Output verification
On board scaling for analog
On board alarming for analog
You will continue to use the project already opened. For this lab we will add the following I/O modules:
1756-IB16D (Diagnostic Input card) in slot 2
1756-OB16D (Diagnostic Output card) in slot 0
1756-IF4XOF2F (Combination Fast Analog card) in slot 3

Page 34 of 93
✒Module Properties Wizard Whenever you add an I/O module, to the system you will go through the Module Configuration Wizard. The Wizard allows you to step through the entire configuration needed for a module. You can access this information later by double clicking on a module in the I/O Configuration folder or through the tag monitor/editor. In Logix there are no more dip switches or jumpers needed to configure I/O modules. I/O modules are software configured. This saves time when setting up a system. The configuration for all modules is part of the controller’s program and is downloaded to the module from the controller; this allows for ease of replacement if an I/O module fails. 7. Enter the Name & Slot parameters as shown below. Leave all other fields set to their default values.
✒FYI Comm Format: Determines the data structure for the tags that are associated with the module. Many I/O modules support different formats. Each format uses a different data structure. Electronic Keying: When you insert a module into a slot of a chassis, the controller compares the information read from the newly inserted module with what the user configured that particular slot to be in their project. The following data is read and compared: Vendor, Product Type, Catalog Number, Major Revision, Minor Revision.
Introduction to Logix Hands-On Lab 4/6/2004
Page 35 of 93
The user may select one of the following module keying options during the initial module configuration: Exact Match – all of the parameters described above must match or the inserted module will reject the connection. Compatible Module – The following criteria must be met, or else the inserted module will reject the connection: Module Types, Catalog Number, and Major Revision must match and the Minor Revision of the physical module must be equal to or greater than the one specified in the software Disable Keying – No keying used at all. 8. Click Next.
✒Requested Packet Interval (RPI) This specifies the period at which data is updated to and from the module. RPIs as configured in milliseconds. The range is .2ms to 750ms.

Assigning Alias Tags In this section of the lab you will learn about Alias Tags. You will continue to use the project already opened.
✒FYI Aliasing An Alias tag lets you create one tag that represents another tag.
Both tags share the same value
When the value of one of the tags changes, the other tag reflects the change
Use Aliases in the following situations:
Program logic in advance of wiring diagrams
Assign a descriptive name to an I/O device
Provide a simpler name for a complex tag
Use a descriptive name for an element of an array
1. From the Controller Organizer double click on MainRoutine.
2. The ladder editor appears.

Motor_Start will now be aliased to Local:2:I.Data.0. This is the 1756-IB16D in Slot 2. 14. Click on OK to close and apply the changes to the tag Motor_Start. Look carefully at the tag for Motor_Start in the ladder code. Under the tag Motor_Start you see < Local:2:I.Data.0>. This means that Motor_Start has been Aliased to Local:2:I.Data.0. This means that the tags are equivalent to one another in code. Is it easier to read Motor_Start than Local:2:I.Data.0.
15. Using steps 4 – 14, alias the remaining two tags. Motor_Stop = Local:2:I.Data.1 Motor_Run = Local:0:O.Data.0
