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.

•The controller name is independent of the project name. You can rename either the project name or the controller name.

In an open project, there is this information:

A

B

C

Item	Description
A	Name of the project. If you rename the project or controller, both names are shown.
B	Name of the controller.
C	The controller organizer is a graphical overview of the project. Use the controller organizer
	to navigate to the various components of a project.

To open a folder and show its contents, either:

•double-click the folder.

•click the + sign.

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

.Bit

= Optional

Where

Is

Location

Network location

LOCAL = same chassis or DIN rail as the controller

ADAPTER_NAME = identifies remote communication adapter or bridge module

Slot

Slot number of I/O module in its chassis or DIN rail

Type

Type of data

I = input

O = output

C = configuration

S = status

Member

Specific data from the I/O module; depends on what type of data the module can store.

• For a digital module, a Data member usually stores the input or output bit values.

• For an analog module, a Channel member (CH#) usually stores the data for a channel.

SubMember

Specific data related to a Member.

Bit

Specific point on a digital I/O module; depends on the size of the I/O module (0-31 for a 32-point module)

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.
	• To call (execute) another routine (subroutine) within the program, use a Jump to
	Subroutine (JSR) instruction.
C	A subroutine is any routine other than the main routine or fault routine. To execute a
	subroutine, use a Jump to Subroutine (JSR) instruction in another routine, such as the main
	routine.

When you create a project, the software automatically creates a main routine that uses the ladder diagram programming language.

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.

		In the following example, an Examine If Closed (XIC) instruction checks the on/off state of a pushbutton. If
	EXAMPLE
		the pushbutton is on, the Output Energize (OTE) instruction turns on a light.

XIC		OTE
If this bit is on…		…turn on this bit. Otherwise,
		turn off this bit.

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. The SCL instruction converts the value to engineering uses and sends it to an
		Output Reference (OREF). The OREF writes the value to an analog output.

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.

•When the data changes, both tags change.

•An alias tag provides a descriptive name for data, such as DeviceNet input or output data.

•If the location of the data changes, simply point the alias tag goes to the new location without editing your logic.

As an option, create tags that describe each device without pointing them to the actual addresses of the devices. Later, convert the tags to aliases for the data of the devices.

1.Enter the logic.

2.Type a descriptive tag name for the device.

3. Right-click the tag name and choose New…

Download a Project to the Controller

To execute a project in a controller, download the project to the controller to transfer a project from your computer to the controller so you can run the project. When you download a project, you lose the project and data that is currently in the controller, if any. If the revision of the controller does not match the revision of the project, you are prompted to update the firmware of the controller. RSLogix 5000 software lets you update the firmware of the controller as part of the download sequence.

	ATTENTION			When you download a project or update firmware, all active servo axes are turned off. Before you
				download a project or update firmware, make sure that this will not cause any unexpected movement of an
				axis.
