Chapter 1 Program and Test a Simple Project This chapter introduces the basic programming sequence for a Logix5000 controller. • It covers the steps required to develop and test a ladder or function block diagram. • The examples in the chapter show how to control a digital or analog output based on the state of a digital or analog input.
Chapter 1 Program and Test a Simple Project Before You Begin To configure and program a Logix5000 controller, you use RSLogix 5000 software to create and manage a project for the controller. A project is the file on your workstation (or server) that stores the logic, configuration, data, and documentation for a controller. • The file for the project has an .ACD extension. • When you create a project, the project name is the same as the name of the controller.
Program and Test a Simple Project Chapter 1 Follow These Steps 1. Create a project for the controller (page 14). 2. Add I/O modules (page 15). 3. Look at I/O data (page 17). 4. Enter ladder logic (page 19). 5. Enter a function block diagram (page 21). 6. Assign alias tags for your devices (page 25). 7. Establish a serial connection to the controller (page 28). 8. Download a project to the controller (page 30). 9. Select the operating mode of the controller (page 32).
Chapter 1 Program and Test a Simple Project Create a Project for the Controller 1. Start RSLogix 5000 software. 2. Click New. 3. Specify the general configuration for the controller. Specify these items (some items apply to only certain controllers): • Type of controller. • Major revision of firmware for the controller. • Name for the controller. • Chassis type for the controller. • Slot number of the controller. • The path where the project will be stored. 4. Click OK.
Program and Test a Simple Project Chapter 1 Conventions for Names Throughout a Logix5000 project, you define names for the different elements of the project, such as the controller, data addresses (tags), routines, and I/O modules. As you enter names, follow these rules.
Chapter 1 Program and Test a Simple Project 2. Select the module and click OK. 3. From the Major Revision pull-down menu, choose the revision of the module. 4. Define the module and click OK.
Program and Test a Simple Project Chapter 1 Look at Your I/O Data I/O information is presented as a set of tags. When you add a module to the I/O Configuration folder… …the software automatically creates controller-scoped tags for the module. An I/O address follows this format. Location :Slot :Type .Member .SubMember .
Chapter 1 Program and Test a Simple Project 1. Right-click Controller Tags and choose Monitor Tags. The Tag Monitor displays the tags. Values are shown in the following styles. Style Base Notation Binary 2 2# Decimal 10 NA Hexadecimal 16 16# Octal 8 8# Exponential NA 0.0000000e+000 Float NA 0.0 A blue arrow indicates that when you change the value, it immediately takes effect. 2. To see a value in a different style, select the desired style. 3.
Program and Test a Simple Project Chapter 1 Ladder Logic For a Logix5000 controller, you enter your logic in routines. A B C Item Description A A routine provides the executable code (logic) for a program (similar to a program file in a PLC or SLC controller). B There is one main routine you assign for each program. • When the program executes, its main routine automatically executes. • Use the main routine to control the execution of the other routines in the program.
Chapter 1 Program and Test a Simple Project Enter Ladder Logic One way to enter logic is to drag buttons from a toolbar to the desired location. A green dot shows a valid placement location (drop point). To add ladder logic, drag the button for the rung or instruction directly to the desired location. You can enter your logic and leave the operands undefined. After you enter a section of logic, go back and assign the operands.
Program and Test a Simple Project Chapter 1 Enter a Function Block Diagram Follow these steps to add a function block diagram to your project. Create a Routine Each routine in your project uses a specific programming language. To program in a different language, such as function block diagram, create a new routine. 1. Right-click MainProgram and choose New Routine. 2. Type a name for the routine. 3. Choose the programming language. 4. Click OK.
Chapter 1 Program and Test a Simple Project Call the Routine To execute a routine other than the main routine, use a Jump to Subroutine (JSR) instruction to call the routine. 1. Add a rung. 2. On the Program Control tab, add a JSR instruction. 3. In the Routine Name field of the JSR instruction, type the name of the routine that you want to execute. 4. To simply call the routine, remove the rest of the parameters for the JSR instruction.
Program and Test a Simple Project Chapter 1 Enter a Function Block Diagram Enter function block diagram instructions in a function block routine. 1. Click the tab for the desired instructions. 2. Drag elements from the toolbar to the sheet. 3. To connect elements, click corresponding pins (green dot = valid connection point). EXAMPLE In the following example, an Input Reference (IREF) reads the value of an analog input and sends the value to a Scale (SCL) instruction.
Chapter 1 Program and Test a Simple Project Configure a Function Block Instruction Assign specific values (parameters) to configure a function block instruction. 1. Click the configuration button. 2. To change the value of a parameter, click the value cell, type the new value, and click Enter.
Program and Test a Simple Project Chapter 1 For example, in the SCL instruction, specify the following parameters: • InRawMax – maximum input value • InRawMin – minimum input value • InEUMax – maximum engineering value • InEUMin – minimum engineering value 3. Click OK. Assign Alias Tags for Your Devices While you can use the input and output tags of a module directly in your logic, it is easier to use alias tags. An alias tag is a tag that represents another tag. • Both tags share the same data.
Chapter 1 Program and Test a Simple Project 4. Select Alias from the menu. 5. Select the tag that this alias tag represents. 6. Select the scope for the alias tag. 7. Click OK. 8. Select the address of the data. To select a bit, click the b button.

Chapter 2 Organize a Project This chapter provides more detailed information on how to organize the program layout and data structures for the controller. What You Need You need these items to complete the tasks in this manual: • Personal computer running RSLogix 5000 software, version 16 or later • A layout of the system for which you are creating a project Before You Begin A new project contains a default task for the execution of your logic.
Chapter 2 Organize a Project Follow These Steps 1. Configure the task execution (page 36). 2. Create additional programs (page 38). 3. Create user-defined data types (page 40). 4. Define your routines (page 43). 5. Assign main routines (page 47). 6. Configure the controller (page 48). 7. Configure I/O modules (page 49). Configure the Task Execution In this quick start, we limit the project to a single task with one of the following types of execution.
Organize a Project Chapter 2 1. Right-click MainTask and choose Properties. 2. Click the Configuration tab. 3. From the Type pull-down menu, choose Periodic. 4. Type the period for the task and click OK. To use multiple tasks or execute a task when a specific event (trigger) occurs, see Logix5000 Controllers Common Procedures, publication 1756-PM001.
Chapter 2 Organize a Project Create Additional Programs A Logix5000 controller lets you divide your application into multiple programs, each with its own tags (data). A C B Item Description A Tag stores data. There is no fixed data table or numeric format for data addresses. The tag name is the address (no cross-reference to a physical address). You create the tags that you want to use. B Program isolates logic and data from other logic and data.
Organize a Project Chapter 2 If you have multiple machines, stations, or processes that use identical logic but different data, create a program for each machine, station, or process. • You can re-use both code and tag names in the programs. • There is no need to manage conflicting tag names between the programs. 1. Right-click MainTask and choose New Program. 2. Type a name for the program and click OK.
Chapter 2 Organize a Project Create User-defined Data Types User-defined data types let you organize your data to match your machine or process. This streamlines program development and creates self-documenting code that is easier to maintain. A B C D E F Item Description A Tag stores data. There is no fixed data table or numeric format for data addresses. The tag name is the address. You create the tags that you want to use.
Organize a Project Chapter 2 As you create user-defined data types, follow these guidelines. Guideline Details Consider the pass-through of descriptions. See User-defined Data Type on page 98. Data that represents an I/O device requires additional programming. If you include members that represent I/O devices, you must use logic to copy the data between the members in the user-defined data type and the corresponding I/O tags.
Chapter 2 Organize a Project 3. Enter the members. As an option, type a description for each member. 4. Click OK. Follow these steps to create a tag that uses a user-defined data type. 1. Right-click the scope that you want for the tag and choose Edit Tags. 2. Type a name for the tag. 3. Type the name of the user-defined data type.
Organize a Project Chapter 2 4. Do the following if you want the tag to be an array (multiple instances of the data type). a. Select the data type and click . b. Specify the array dimensions and click OK. Define Your Routines Once your project has the required programs, you have to define and create the routines for each program. A B C Item Description A Routine provides the executable code (logic) for a program (similar to a program file in a PLC or SLC controller).
Chapter 2 Organize a Project Define a Routine for Each Section of Your Machine or Process To make your project easier to develop, test, and troubleshoot, divide it into routines (subroutines). 1. Identify each physical section of your machine or process. 2. Assign a routine for each of those sections.
Organize a Project Chapter 2 Assign a Programming Language to Each Routine For each routine, choose a programming language. • Logix5000 controllers let you use the following languages: – Ladder logic – Function block diagram – Sequential function chart – Structured text • Use any combination of the languages in the same project.
Chapter 2 Organize a Project Divide Each Routine Into More Meaningful Increments If a routine uses this language Then Example Ladder logic Break up large routines into several smaller routines To continuously execute several complex boolean operations… Structured text routine Function block diagram (FBD) routine Within the FBD routine, make a sheet for each functional loop for a device, such as a motor or valve.
Organize a Project Chapter 2 Assign Main Routines Each program requires a main routine. Once you create your routines, assign a main routine for each program. IMPORTANT In the default project, MainProgram already has a main routine (MainRoutine). You have to assign a main routine only for each additional program that you create. Follow these steps to assign a main routine. 1. Right-click the program folder and choose Properties. 2. Click the Configuration tab. 3. Select the main routine and click OK.
Chapter 2 Organize a Project Configure the Controller If you want to change the configuration of the controller, such as name, chassis size, or slot number, use the Controller Properties dialog box. 1. Click the Controller Properties button. 2. Change the required properties (some items apply only to certain controllers) and click OK.
Organize a Project Chapter 2 Configure I/O Modules To change the behavior of a module, use the Module Properties window for the module. The configuration options vary from module to module. 1. Right-click the module and choose Properties. 2. To change the name or slot number, use the General tab. 3. To change the configuration, click the Configuration tab. Some modules have several configuration tabs.

Structured text can contain these components. A B C D E Item Description A Construct defines logical conditions for the execution of other structured text code (other statements). In this example, the construct is If…Then…Else…End_if. B BOOL expression checks if a tag or equation is true or false.
Program a Project Offline Guideline Description Write BOOL expressions as either true or false Use a BOOL expression to determine if specific conditions are true (1) or false (0). Chapter 5 • A BOOL tag is already true (1) or false (0). Do not use an “=” sign to check its state. This is OK This is NOT OK If Bool1 … If Bool1 = 1 … If Not(Bool2) … If Bool2 = 0 … • To check an integer, REAL, or string, make a comparison (=, <, <=, >, >=, <>). For an assignment, start with the destination.
Chapter 5 Program a Project Offline Assign Operands to an Instruction 1. Right-click the instruction and choose Argument List. 2. For each parameter, select a tag or type an immediate value. 3. Click OK.
Program a Project Offline Chapter 5 Enter a Sequential Function Chart A sequential function chart (SFC) lets you define a sequence of states (steps) through which your machine or process progresses. The steps can execute structured text, call subroutines, or simply serve as signals for other logic. A B C D E Item Description A Step is major function of your process. It contains the actions that occur at a particular time, phase, or station. B Action is one of the functions that a step performs.
Chapter 5 Program a Project Offline Enter an SFC 1. Drag elements from the toolbar to the chart. • A green dot shows a point to which the element will automatically connect if you release the mouse button. • Some toolbar buttons are active only after you select a corresponding element on the SFC. For example, to add an action, first select a step. • Drag an action until it is on top of the required step and then release the mouse button. 2. To manually connect elements, click corresponding pins.
Program a Project Offline Chapter 5 Assign Operands RSLogix 5000 software lets you program according to your workflow. You can enter logic without assigning operands or defining tags. Later, you can go back and assign or define the operands to complete the logic. A B Item Description A This instruction is missing an operand. You can enter and save logic without assigning operands. This lets you develop your logic in iterations and save libraries of code for re-use. B This is an undefined tag.
Chapter 5 Program a Project Offline Where Is Name Name that identifies this specific tag. Element Subscript or subscripts that point to a specific element within an array. • Use the element identifier only if the tag or member is an array. • Use one subscript for each dimension of the array. For example: [5], [2,8], [3,2,7]. To indirectly (dynamically) reference an element, use a tag or numeric expression that provides the element number.
Program a Project Offline Chapter 5 5. Choose the scope for the tag. 6. Click OK. Select an Existing Tag 1. Double-click the tag area. 2. Click the b. 3. Select the desired tag.
Chapter 5 Program a Project Offline To select a bit, click the b. 4. To change the scope of tags in which to look, click the appropriate button. Verify a Project As you program your project, periodically verify your work.
Program a Project Offline Chapter 5 Item Description Verify Check a routine or project for programming errors or incomplete configuration. Warning A situation that may prevent the project from executing as expected. RSLogix 5000 software lets you download a project that contains warnings. Warnings include situations such as duplicate destructive bits and unassigned main routines. Error A situation that you must correct before you download the project.
Chapter 5 Program a Project Offline 4. To turn off duplicate destructive bit detection (it’s on by default), from the Tools menu, choose Options. Guidelines for Tags Use the following guidelines to create tags for a Logix5000 project. Guideline Details Create user-defined data types. User-defined data types (structures) let you organize your data to match your machine or process.
Program a Project Offline Chapter 5 Guideline Details Take advantage of program-scoped tags. If you want multiple tags with the same name, define each tag at the program scope (program tags) for a different program. This lets you re-use both logic and tag names in multiple programs. Avoid using the same name for both a controller tag and a program tag. Within a program, you cannot reference a controller tag if a tag of the same name exists as a program tag for that program.
Chapter 5 Program a Project Offline Guideline Details Limit a tag name to 40 characters. Here are the rules for a tag name: • Only alphabetic characters (A-Z or a-z), numeric characters (0-9), and underscores (_) • Must start with an alphabetic character or an underscore • No more than 40 characters • No consecutive or trailing underscore characters (_) • Not case sensitive Use mixed case. Although tags are not case sensitive (upper case A is the same as lower case a), mixed case is easier to read.
