MicroLogix 1000 and PLC-500 A.I. Series Software Reference

System Configuration

The following sections discuss the steps necessary to assure smooth software start-up and operation. This information is written for running your A.I. Series software in DOS. Exceptions and considerations for running under Windows™ operating systems (Windows, Windows 95, and Windows NT™) are noted.

AUTOEXEC.BAT File

There are no required statements in the AUTOEXEC.BAT file. If you want to start the PLC-500 A.I. software automatically when your computer is restarted, or to start the software from a different batch file, make sure you include the following statements in the batch file:

Statement Function

CD\SLC500

AB500

Change to the drive where PLC-500 A.I. is installed

Change to the directory where PLC-500 A.I. is installed

Start PLC-500 A.I. (at the main menu)

1-18

You can also include a statement in the batch file that sets an environment variable which places user configuration files in a directory other than the SLC500 directory. This statement is required in multi-user and network installations.

The statement is:

SET PLCLL=C:\USER1

where C:\USER1 is an existing subdirectory. If you use the environment variable, copy the file SLC5LL.DEF from the product directory (usually \SLC500) to the specified directory. This loads the default status file word/bit descriptions automatically when a new database is loaded. Refer to the A.I. Series Installation Guide for more information on network and multi-user installation.

If your system has 4 M of RAM (at least 8 M if using a Windows operating system),

you can add the following line to your AUTOEXEC.BAT file to improve software

performance.

C:\DOS\SMARTDRV.EXE 1024

Once you have added this line and rebooted your computer, check to make sure that at

least 3M of RAM is free. Type MEM [Enter] at the DOS prompt. Look at the number

under the “Free” column for “Extended (XMS)” memory; it should be greater than or

equal to 3072. If it is less than 3072, decrease the RAM that is being allocated to

SMARTDRV.EXE, reboot, and check again. (For additional information on

SMARTDRV.EXE, see your DOS manual or type help smartdrv.exe at the DOS

prompt.)

CONFIG.SYS File

This file must be in the root directory of the drive that your computer boots from

(typically drive “C” for a hard disk based system). This file is not needed if you are

using Windows 95 or NT.

The CONFIG.SYS file should contain the following statements:

Introduction

DEVICE=C:\DOS\HIMEM.SYS

DEVICE=C:\DOS\EMM386.EXE NOEMS

DOS=HIGH

FILES=40

BUFFERS=30

Note The path in your DEVICE statements may be slightly different if you are running

Windows, for example, C:\WINDOWS\HIMEM.SYS or C:\WFW\HIMEM.SYS.

Specifying quantities greater than those listed above are generally acceptable, but

additional buffers will subtract from your available RAM. Use a text editor to modify

or create the CONFIG.SYS file if necessary.

Note If the CONFIG.SYS file is added or edited, you will need to “warm boot” your

computer (press [Ctrl-Alt-Del]) before the changes take effect.

1-19

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

RAM Considerations

PLC-500 A.I. requires an 80386 or faster processor and at least 3 M of extended memory (XMS) free. If your system has less than 3 M of available RAM, the software will be forced to use a swap file on your hard drive, which slows down many software operations considerably.

Note If you are running under Windows, be sure to shell to DOS to check your free memory.

An ideal system would contain at least 8 M of RAM, where at least 3 M of RAM is available after allocating some memory to a disk cache (such as MS-DOS’s Smartdrv).

The version of MS-DOS on your system also affects the amount of available RAM. Although the software can run on MS-DOS 4.01 and 5.0, consider MS-DOS 6.0 as the minimum version due to its advanced memory management features.

PLC-500 A.I. no longer has a minimum conventional RAM requirement of about 580K. As long as you have more than 500K free conventional memory (and at least 3 M of XMS memory free), you will be able to run the software without memory errors.

1-20

About Memory Managers

A memory manager is a software program that manages the use of memory in your

computer. If your computer has any expanded memory (EMS) or extended memory

(XMS) installed, you may be using some sort of memory manager.

In certain configurations, some memory managers may conflict with the following DH-

485 and DH+ network interface cards.

• Allen-Bradley 1784-KT

• Allen-Bradley 1784-KTX

• Allen-Bradley 1784-KL

• Allen-Bradley 1784-KT2

• Allen-Bradley 1784-KR

• Allen-Bradley 1784-PCMK

• S-S Technologies, Inc. 5136-SD

• S-S Technologies, Inc. 5136-SD2

Introduction

This section describes how to avoid these conflicts.

386MAX.SYS

386MAX.SYS is a memory manager produced by Qualitas, Inc.

There is an easy method to avoiding 386MAX conflicts with the interface cards.

386MAX is shipped with a program called MAXIMIZE.EXE. This program examines

your computer and makes certain that it won’t create memory conflicts with your

existing hardware. If you use MAXIMIZE.EXE to configure 386MAX, you should

have no conflicts with your interface. See the 386MAX User’s Guide for more details.

QEMM.SYS

QEMM.SYS is a memory manager produced by Quarterdeck, Inc.

1-21

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

The command line in your CONFIG.SYS file which starts QEMM.SYS can be modified to avoid your DH-485 and DH+ interface cards. Use the “EXCLUDE” statement to tell QEMM.SYS which addresses to avoid. An example of a command which avoids an Allen-Bradley 1784-KT with a memory address of D800 is shown below.

DEVICE=C:\QEMM\QEMM.SYS EXCLUDE=DB00-DBFF

A second example shows a command which avoids the Allen-Bradley 1784-KL in the A-B T47 Programming Terminal.

DEVICE=C:\QEMM\QEMM.SYS EXCLUDE=E000-E0FF

EMM386.EXE

EMM386.EXE is a memory manager provided with MS-DOS. The command line in your CONFIG.SYS file which starts EMM386.EXE can be

modified to avoid your DH-485 and DH+ interface cards. Use the “EXCLUDE” statement to tell EMM386.EXE which addresses to avoid. An example of a command which avoids an Allen-Bradley 1784-KT with a memory address of D800 is shown below.

1-22

DEVICE=C:\DOS\EMM386.EXE EXCLUDE=DB00-DBFF

A second example shows a command which avoids the Allen-Bradley 1784-KL in the A-B T47 Programming Terminal.

DEVICE=C:\DOS\EMM386.EXE EXCLUDE=E000-E0FF

Communications Hardware

You can transfer programs to and from the SLC 500 and monitor online operations

using a Rockwell Software product and one of the following protocols depending on

your SLC 500 processor: DH-485, DH+, or RS-232. Refer to Allen-Bradley’s data

sheets or hardware manuals to determine valid network configurations.

For information on configuring communications hardware to operate with

PLC-500 A.I., refer to Chapter 15 - Configuration for Online Communications.

NT Users: Only serial drivers (except the 1747-PIC) will work when running PLC-

500 A.I. under Windows NT. RSI is working on a version of the software that will

contain special drivers to communicate through RSLinx™. This will allow you to

communicate using any of the drivers available with RSLinx.

Introduction

1-23

2 Handling Project Files

There is a specific order of events to follow when you create a ladder logic program

using PLC-500 A.I. This chapter will tell you how to accomplish step 1 below.

1. Create a project. Projects are the set of files having to do with a ladder program.

There are a variety of files in a project, but PLC-500 A.I. creates the files automatically, whenever you need them. Creating a project is as simple as giving it a name that PLC-500 A.I. can use to refer to the files.

2. Configure the processor type and I/O. This process tells PLC-500 A.I. what type of

programmable controller module and I/O modules you are using, and allows PLC500 A.I. to address the I/O points. The features available in the software vary with processor type, so defining the processor type is very important. Chapter 3 - Configuring the PLC-500 CPU and I/O Modules discusses this step.

3. Enter and document the ladder program for the project. This is the actual program

you will use in your SLC 500 processor. This step is discussed in Chapter 6 -

Creating and Editing Ladder Logic and in Chapter 8 - Adding Descriptive Text to Ladder Logic.

The File Selector feature of PLC-500 A.I. provides a tool for handling files. This

chapter will explain how to use the File Selector to create a new project file, select an

existing project, and use file utilities for such functions as deleting and backing up files.

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Components of a Project File

Notes on terminology: The term processor file used in this manual is equivalent to the term program used in Hand-Held Terminal (HHT) displays. Both of these terms mean the collective “program files” and “data files” created within the particular processor file name or program name. The term processor file does not include the description database files.

Most of the operations you perform with a SLC-500 processor involve a project file. A project file consists of the database files and the processor files. Processor files consist of program files and data files.

Refer to Appendix A - PLC-500 A.I. File Extensions for information on the file extensions shown in the diagram above.

2-2

Program Files

Program files contain controller information, the main ladder program, and any

subroutine programs. The first three program files are required for each project:

• The system program file (file 0) is always included. It contains various system

related information and user-programmed information such as processor type, I/O configuration, processor file name and password.

• File 1 is reserved for future use.

• The main ladder program file (file 2) is always included. It contains user-

programmed instructions defining how the controller is to operate.

• Subroutine ladder program files (files 3 - 255) are created by the user and

activated or “called” from the main ladder program using subroutine instructions. (This does not apply to the MicroLogix controller. See below.)

The Fault Routine, Discrete I/O Interrupts, STI Interrupts, and I/O Event Driven

Interrupts require subroutine program files.

MicroLogix Controller Differences

The system program (file 0) and main ladder program (file 2) are as listed above. Files

3 and higher are listed below:

• The user error fault routine (file 3) is executed when a recoverable fault occurs.

• The high-speed counter interrupt (file 4) executes when an HSC interrupt occurs.

This file can also be used for a subroutine ladder program.

• The selectable timed interrupt (file 5) executes when an STI occurs. This file

can also be used for a subroutine ladder program.

• Subroutine ladder program files (files 6-15) are used according to subroutine

instructions residing in the main ladder program file or other subroutine files.

Handling Project Files

Data Files

These files contain the data associated with the instructions in the ladder program files.

In addition, these files store information concerning processor operation. You can also

use the files to store “recipes” and look-up tables if needed. Each project can contain

up to 256 data files (except for MicroLogix). These files are organized by the type of

data they contain.

2-3

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

MicroLogix

The MicroLogix controller provides 8 default data files (0-7) and no user-defined data files. Data file types are listed below.

Fixed, SLC 5/01, SLC 5/02, and 5/03 OS300

The first eight data files (0-7) have default types. File 8 is reserved for future use. You designate the file types for the remainder of the files (9-255).

SLC 5/03 OS301 and up, and SLC 5/04

The first nine data files (0-8) have default types. You designate the file types for the remainder of the files (9-255).

Data File Types

The default data file types are:

• O Output (file 0): This file stores the state of the output terminals for the

controller.

• I Input (file 1): This file stores the status of the input terminals for the controller.

• S Status (file 2): This file stores controller operation information. This file is

useful for troubleshooting controller and program operation.

• B Binary or Bit (file 3): This file is used for internal relay logic storage.

• T Timer (file 4): This file stores the timer accumulated and preset values and

status bits.

• C Counter (file 5): This file stores the counter accumulated and preset values and

the status bits.

• R Control (file 6): This file stores the length, pointer position, and status bits for

specific instructions such as shift registers and sequencers.

• N Integer (file 7): This file is used to store numeric values or bit information.

Values range from -32768 to 32767.

2-4

• F Floating Point (file 8): Only SLC 5/03 OS301 and SLC 5/04 OS400 processors

and higher use floating point. This file stores single precision non-extended 32-bit numbers. The valid range is ±1.1754944e

-38

to ±3.40282347e

+38

• User-Defined (file 9-255): These files are user-defined as bit, timer, counter,

Database Files

The database files contain descriptions you have added to your ladder logic. These

include instruction descriptions, rung descriptions, instruction symbols, and page titles.

Processor Files

A processor file contains the collection of program files and data files created under a

particular processor file name. As such, it contains all the instructions, data, and

configuration information pertaining to a user program. We refer to the program and

data files separately, however, they are both contained in the .ACH file.

The processor file is a transferable unit. It can be located in the Rockwell Software

programming terminal (or in the Hand-Held Terminal). Processor files residing in a

programming terminal can be transferred to/from a MicroLogix 1000, SLC 500, 5/01,

5/02, 5/03, or 5/04 processor, or to/from a memory module (i.e., EEPROM) located in

the SLC 500 processor.

Processor files residing in the Hand-Held Terminal can only be transferred to or from a

SLC 500, 5/01, or 5/02 processor or to or from a memory module located in one of

those processors. You cannot use a Hand-Held Terminal to transfer processor files to

or from an SLC 5/03 or 5/04 processor. You can use a Hand Held Programmer to

transfer files to and from a MicroLogix controller.

Creating a New Project

Access the File Selector to create a new project:

1. From the Main Menu, select [F1] Select Program/SLC-500 Addr. The File

Selector appears.

Handling Project Files

The File Selector consists of two windows. The left window shows the files in the current directory, and the right window lists the current directory, search specification, and the options available to you.

2. Make sure the Current Directory field shows the directory in which you would like

to store your new file. If not, see Current Directory on page 2-13 for directions on changing the current directory.

2-7

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

3. Press [Ins] to create a new project file. A window appears, prompting you for a

project name.

4. Type a name for the project, and press [Enter] to accept the name. The name for

the project must be eight characters or fewer in length, and must not contain characters that violate standard DOS naming conventions (/ \ . : or a blank space). Do not type a file extension. The utility automatically adds the appropriate file extension to the filename, and places it in the Current Directory.

Note If you want to use your file later with Allen-Bradley APS software, use only

alphanumeric (A-Z, 0-9) and underscores (_) in your filenames. APS software will not recognize filenames containing other characters.

5. Set the SLC 500 station address for the project. After you name a new project with

the File Selector, PLC-500 A.I. asks you to identify the address of the SLC 500 for which you are creating this project.

This is the DH-485 network node number or, for SLC 5/04 processors, the DH+ network node number. To set the station address:

• backspace to remove the default of 1

• type the address.

2-8

• press [Enter] to accept the address. The software will return to the Main

Menu.

The project files won’t actually be created until you edit (go Offline with) the project

(see Editing a New Project below).

If you are editing offline, you can change the SLC 500 address at any time while

editing the ladder.

Modifying the SLC 500 Address

The SLC 500 address shown in the upper right corner of the File Selector screen shows

the default destination DH-485 (or DH+) node address for the currently selected

working project. When you go online with that project, PLC-500 A.I. begins looking

for a SLC 500 at the address you select. If it does not find a SLC 500 at that address,

PLC-500 A.I. displays the Who Active screen, and allows you to choose a different

SLC 500 address for the project. This address is then saved as the new default.

To modify the SLC 500 address for a project:

1. With the File Selector utility displayed on your screen, highlight the desired file.

Handling Project Files

2. Select [F1] Modify Addr.

3. The utility prompts you to enter a SLC 500 station address. The current station

address is displayed in the prompt. Enter the new address, 0-31 decimal. (With a SLC 5/04 processor, you can use DH+ addresses 0-77 octal, but you must configure the interface before you can modify the address. See below.) Press [Enter] to accept the address.

Configuring the Interface for DH+ Communication With a SLC 5/04

If you want to select a DH+ address higher than 31 (from 0-77) for your SLC 5/04

processor, you must first configure the interface.

1. From the Main Menu, select [F9] Configure Program Parameters.

2. Select [F1] Communication Hardware.

3. Select [F2] Interface Hardware Type.

4. Select [F3] DH+ Communication Devices, then select a driver.

2-9

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

5. Press [Esc]. You will be asked to save the configuration. Select [F1] Yes. Now when you modify the address as described above, the software will prompt you for

a DH+ station address between 0 and 77 (octal).

Editing a New Project

The first time you attempt to edit a new project with [F2] Offline Programming/Doc on the Main Menu PLC-500 A.I. will display the prompt shown below.

Select [F1] Yes to create the project files. PLC-500 A.I. prompts you to select the processor type. See Chapter 3 -Configuring the PLC-500 CPU and I/O Modules for information on configuring the system. If you select [F5] No, the new program files are not created and the File Selector utility appears. See Selecting a Project File on the following page for information on using the File Selector to choose a different project file.

2-10

Selecting a Project File

Use the File Selector to choose an existing file. Simply highlight the file using the

arrow keys and press [Enter]. You may also highlight files by typing in the name from

the keyboard. For instance, typing the letter “M” will highlight the first file in the list

beginning with the letter “M.” Entering subsequent letters in a name will find the file

matching the name you typed.

The rest of this section describes in more detail how to navigate File Selector to find

your file if you do not see it listed initially.

File List

From the Main Menu, select [F1] Select Program/SLC-500 Addr. The File Selector

appears.

Handling Project Files

The File Selector appears as two windows. The right window lists the current

directory, search specification, and the options available to you, and the left window

shows the files in the current directory. The list shows only those files with the

filename extension shown in the Search Specification.

Note The Search Specification cannot be changed by the user. See the section on Search

Specification below.

2-11

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

The file list shows the filename, the size of the file, and the date the file was last modified. If you are selecting a project file (*.ACH), the file list also shows a SLC 500 address for the project; otherwise, the file list shows the time when the file was last saved.

Three items in the file list control which directory is displayed:

1. MAKE NEW DIRECTORY/CHANGE DRIVE: Select this item to change the

current drive and/or directory. If no file is selected, this is usually the default. When you press [Enter] with this line highlighted, a prompt will appear for a new subdirectory. If you type a new name at this point, the software will create a subdirectory (not a project) with that name.

2. . <DIR> CURRENT DIRECTORY: Select this item to redisplay the contents of

the current directory. Use this when you are reading from a floppy disk drive and you change disks, or when you are on a networked drive and the contents of the drive are changing. If this option is not shown, then the default directory in the right-hand window does not exist.

3. . . <DIR> PARENT DIRECTORY: Select this to move up one level in the

directory structure.

Search Specification

The Search Specification indicates the file extension of the files in the list. All of the files in the list on the left of the screen will have this extension.

You cannot change the Search Specification; it is determined by how the File Selector screen was called. For instance, when you call the File Selector from the Main Menu with [F1] Select Program/SLC 500 Addr, the Search Specification looks for .ACH files. When you select a program database for editing, PLC-500 A.I. looks for .ACH files, because the .ACH file uniquely identifies the project, and thus the database. When you select a printer configuration, PLC-500 A.I. calls the File Selector screen. In this case, the Search Specification looks for a .RCF file.

2-12

Handling Project Files

Current Directory

The Current Directory field in the right window shows the directory where the File

Selector is searching for files. The default Current Directory is the directory where you

store your program files.

There are two ways to change the current directory. You can directly specify the

pathname, or you can select it by cursoring through the directory structure using the

..<DIR> Parent Directory or highlighting a directory name on the left and pressing

[Enter].

Note To use files from a different disk drive, you must directly specify the path to the drive.

For instance, to change to drive B:, you must specify the root directory as B:. You

can then cursor through the directory structure of B: to find the files.

To directly specify a pathname:

1. Use the [Home] key (or the up arrow key) to move the highlight bar in the left

window to MAKE NEW DIRECTORY/CHANGE DRIVE.

2. Press [Enter]. The File Selector prompts you to enter a new pathname.

3. Type the pathname, and press [Enter]. If the directory exists, the File Selector

shows the files in that directory. If the directory does not exist, the File Selector creates it.

To select a directory to change to:

1. Using the up and down arrow keys, move the highlight bar in the left window to

.. <DIR> PARENT DIRECTORY.

2. Press [Enter]. The left window refreshes, showing the files in the directory

directly above the old directory. Notice the old directory is shown in the file list with <DIR> next to the directory name.

3. You can move up and down through the directory structure by selecting parent

directories and subdirectories. Subdirectories are indicated by a <DIR> after their name on the left. When you locate the file you want, move the highlight bar to the file name, and press [Enter] to select the file.

2-13

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Sorting the File List

You can change the order in which files appear in the file list. You can sort by file/directory name, file extension, the date the file was last modified, or the file size. To toggle the order, press [F9] Sort Mode.

To change the sort mode:

1. With the File Selector utility displayed on your screen, press [F9].

2. The system displays the new sort mode and re-sorts the files in the list. Continue

pressing [F9] until the files are sorted the way you want them.

The available sort modes are:

Sort mode Description

Name Sort alphabetically by file name.

Ext Sort by extension. In most cases there are directories and only one

type of file displayed. Since directories usually don’t have extensions, they are listed first.

Date Sort by file date and time. Sorts the files so the oldest appears at the

top.

Size Sort the files by size. Since a directory doesn’t have a file size per-se,

directories are listed first.

2-14

File Utilities

When you use the File Selector utility from the Main Menu or from the Reporting

Options menu, the File Selector gives you access to several file utilities. Use these

utilities for copying, renaming, deleting, backing up, and restoring files.

Copying Files

To copy project files:

1. With the File Selector utility screen displayed, highlight the project name you want

to copy. If this is the only file you want to copy, go on to step 2. If you want to copy more than one ladder/database, press [F5] Mark File for Copy. Highlight the next file and press [F5] Mark File for Copy again. Repeat for the remainder of the projects you want to copy.

2. Press [Tab]. The utility presents you with a list of file utilities.

Handling Project Files

3. Select [F1] Copy file(s).

4. The utility asks you which files you want to copy: the processor memory files,

description database files, or all of the files for the project. Select the type of files you want to copy.

2-15

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

5. The utility asks you to specify a pathname for the copied files. Type the pathname,

and press [Enter]. As the utility copies the files, it shows you the name of the file currently being copied.

Note If the name you enter ends with a backslash (\), or if you have highlighted multiple

files, the system considers the name you entered to be a directory name. Otherwise, the name you enter is used as the name of the new file. For example, if you select OLDPROG.ACH and copy to …\NEWPROG, you end up with NEWPROG.ACH. If you copy it to …\NEWPROG\, you get …\NEWPROG\OLDPROG.ACH. If you mark OLDPROG1.ACH and OLDPROG2.ACH and copy them to either …\NEWPROG or …\NEWPROG\, you will end up with …\NEWPROG\OLDPROG1.ACH and …\NEWPROG\OLDPROG2.ACH.

Renaming Files

To rename project files:

1. With the File Selector utility screen displayed, highlight the project name you want

to rename. Press [F5] Mark File for Copy to perform the operation on more than one ladder/database. Repeat this step for the remainder of the projects you want to rename.

2-16

2. Press [Tab]. The utility presents you with a list of file utilities.

3. Select [F2] Rename file(s).

4. The utility asks you which files you want to rename: the processor memory files,

description database files, or all of the files for the project. Select the type of files you want to rename. The utility asks you to specify a new name for the selected files.

(See the note above under Copying Files for information on specifying file names and directories.)

Handling Project Files

Deleting Files

To selectively delete project files:

1. With the File Selector utility screen displayed, highlight the project name you want

to delete. Press [F5] Mark File for Copy. Repeat this step for the remainder of the projects you want to delete.

2. Press [Tab]. The utility presents you with a list of file utilities.

3. Select [F3] Delete file(s).

4. The utility asks you which files you want to delete: the processor memory files,

description database files, or all of the files for the project. Select the type of files you want to delete. The utility prompts you before deleting each of the files associated with the project.

Note If you want to delete only one project file, you can highlight the file with the File

Selector, and press [Del]. This deletes the entire project, both processor memory and

the description database. The system warns you that you are about to delete the files.

Backing Up Files

Backup files are now stored in a compressed format (so fewer diskettes are needed), but

early versions of PLC-500 A.I. used an uncompressed format. The new restore function

is capable of restoring new or old backups. The old restore function cannot restore

backups made with software versions 6.0 and higher.

Calculating Number of Disks for a Backup

Backups sometimes require several floppy disks to hold all of the files. To perform a

backup, you need to have enough formatted disks to hold all of the files. You cannot

stop a backup part of the way through to format more disks, so PLC-500 A.I. has a

utility that calculates the number of disks you will need to back up your files. (Skip this

step if you are backing up to a network drive or hard disk.)

To calculate the number of disks you will need for a backup:

1. With the File Selector utility screen displayed, highlight the project name you want

to back up. If you want to backup multiple projects, highlight each project and press [F5] Mark File for Copy to mark each one.

2-17

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

2. Press [Tab]. The utility presents you with a list of file utilities.

3. Select [F7] Calculate Disks Required for Backup. The utility asks you which

files you want to back up: the processor memory files, description database files, or all of the files for the project.

4. Select the file type you want to back up. The utility calculates the number of disks

you will need to back up the files you selected. The utility calculates the number of disks for four different disk formats:

• 5-1/4 inch, 360KB

• 5-1/4 inch, 1.2MB

• 3-1/2 inch, 720KB

• 3-1/2 inch, 1.4MB

The number of disks is displayed as a range. For example, “1-2” would mean that you will need one or two disks to perform the backup.

Formatting Disks for Backups

(Skip this step if you are backing up to a network drive or a hard disk.)

Before you can use a floppy disk, it must be prepared to accept data. The process of preparing the disk is called formatting. PLC-500 A.I. contains a utility that allows you to format disks.

Note The formatting utility in PLC-500 A.I. is the same as the DOS format utility run without

switches. You must have a path set up to the directory containing the DOS Format command or a “spawn error-1” will be displayed.

To format disks:

1. With the File Selector utility screen displayed, press [Tab]. The utility presents

you with a list of file utilities.

2. From the list of utilities, select [F6] Format Disk(s) for Backup. The utility asks

you which drive you want to use to format the disk. For safety reasons, only drives A: and B: are available for this option. To format disks in drives other than A: or B:, exit to DOS and use the format command from the DOS prompt.

2-18

Backing Up

Handling Project Files

3. Select the floppy drive you want to use for formatting the disk. The utility warns

you that all information on the floppy disk in the drive will be lost. Select [F1] Yes to continue formatting.

4. The utility prompts you to insert the disk to format in the drive you selected. Insert

the disk, and press [Enter] to begin formatting.

5. The utility formats the disk. When it finishes formatting the disk, the utility asks

you if you want to format another disk. If you answer yes, the utility asks you to put the next disk into the floppy drive and press [Enter]. Repeat this step until you format all of the disks you will need for your backup.

To backup project files:

1. With the File Selector utility screen displayed, highlight the project name you want

to backup. If you want to backup multiple projects, highlight each project and press [F5] Mark File for Copy to mark each one.

2. Press [Tab]. The utility presents you with a list of file utilities.

3. Select [F4] Backup file(s).

4. The utility asks you which files you want to back up: the processor memory files,

description database files, or all of the files for the project. Select the type of files you want to back up.

5. The utility asks you to select a disk drive for the backup files. Select a disk drive.

Note Versions of PLC-500 A.I. prior to version 7.xx only allowed you to backup to drive A

or B. Now you can backup to any drive—including a network drive or your hard disk.

6. The utility asks you to enter a description of the backed-up files for future

reference. This description is used when you restore files from backup. Type the description, and press [Enter]. (See Restoring Files.)

2-19

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

7. The utility asks you to insert backup disk #1 in the drive you selected, and warns

you that the information in the root directory of the floppy disk will be erased. If you are backing up to floppy disks, make sure you have a formatted floppy disk in the disk drive, and enough floppy disks to back up all the files you selected. See Format Disks for Backup, and Calculating Number of Disks for a Backup, above. Press [Enter] to begin the backup process.

8. As the utility backs up the project files, it displays the filenames for the files.

When the first disk fills with files, the utility asks you for another disk. This process continues until all the files you selected are backed up to floppy disk.

Note Backup files are not saved in the DOS backup format. They are saved in a special

archived format. To use the files, you must decompress them using the Restore file(s) utility. See Restoring Files.

Restoring files

To restore project files from a backup:

1. With the File Selector utility screen displayed, press [Tab]. The utility presents

you with a list of file utilities.

2-20

2. Select [F5] Restore file(s).

3. The utility asks you from which drive you want to restore files. Select the drive

from which you will restore the files.

• If you selected a floppy disk drive, the utility asks you to insert the first backup

disk into the floppy drive you selected. Insert the disk, and press [Enter].

• If you selected [F3] Select Drive/Path, the system prompts you to enter the

directory. Type the drive and directory and press [Enter].

4. The utility displays the description of the backup, and shows you the directory from

which the files were backed up, and the time and date when the backup was made. The utility also asks you to specify the directory to which you want to restore the files (the target directory). Type the pathname for the directory, and press [Enter].

Handling Project Files

5. The utility begins restoring files to the directory you chose. If a file you are

restoring does not currently exist in the target directory, the utility restores the file from the disk. If the file already exists in the target directory, the utility prompts you before overwriting the file. If you answer yes to this prompt, the utility overwrites the file in the hard disk directory with the backup file. If you answer no to the prompt, the utility skips restoring that file.

Note If the restore function continually requests a disk without restoring any files, the disks

are probably copies of the backup set. You must restore from an original backup set.

Note Versions of the Restore utility prior to version 6.0 will not be able to read backups

created using the new file-compressing Backup utility.

6. If you are restoring from floppy disks, after all of the files from the first disk are

restored, the utility asks you to insert the next disk into the floppy drive. (If your backup took only one disk, the restoration is complete.) Insert the next disk into the drive, and press [Enter]. Repeat this process until all of the files are restored.

(For an existing project , access the configuration screen from the top menu of the offline editor by selecting [F6] Utility and then [F3] Type/sr.)

This screen displays the processor type, the racks, and the I/O cards, all of which are configurable. For the project to run correctly, all the information must reflect the actual hardware.

The first step in the system configuration is to select the processor type. The processor type selection affects what other options are available. For example, a modular processor must have a rack.

Configuring the SLC 500 CPU and I/O Modules

To select the processor type:

1. The first time you edit a new project and create the project file, PLC-500 A.I.

displays the following screen.

(To change the processor type for an existing project, access the SLC 500 Processor

- I/O Configuration Screen, as described on page 3-2 . Select [F1] Proctyp. A list of processor types will appear.)

2. Use the arrow keys to highlight the correct processor. If you are not sure which

processor type you are using, check the label on the side of the processor. In modular hardware configurations, you will have to pull the processor out of the rack to see the label.

3. Press [Enter] to select the highlighted processor.

Note If you have a SLC 5/03 or 5/04 processor, you can automatically configure I/O racks

and cards (rather than manually as explained in the two following sections). The

processor type must be selected as described above and the communications device

must be configured and connected. From the Processor I/O Configuration screen,

press [F3] Readcfg.

3-3

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Note If you change the processor configuration for an existing program containing indirect

addresses to a processor that does not support indirect addressing, errors will occur. PLC-500 A.I. will allow you to save the program with the errors (press [Esc] to continue when the error list is displayed). Indirect addresses will remain as they were in the original program. You must edit these addresses before attempting to run the program with the new processor.

Rack Configuration

After you select the processor type, you must configure the rack or racks. Rack configuration depends on whether you have a fixed I/O system or a modular system. Rack configuration is not applicable with a MicroLogix 1000 controller.

Modular Processor

If you have selected a modular processor, you must configure the rack or racks as follows:

(For an existing project, access the SLC 500 Processor - I/O Configuration Screen, as described on page 3-2.)

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

The Processor Status Screen for a SLC 5/03 or 5/04 processor has four screens of data that you can access by pressing the [Page Up] and [Page Down] keys. The Processor Status Screen for a 5/02 processor has two screens of data. For all other SLC 500 processors, this is a single screen. The first screen of the display contains the Processor Status Bits covered in this chapter.

Fault Override at Powerup (S:1/8)

This bit controls the state the processor starts up in when powered up. If the processor was running and went into a fault mode before the power went down,

and this bit is on, the fault will be cleared when the processor is powered up, and the processor will attempt to go into run mode.

If the processor is not faulted, it will power up in the same state it powered down in. This bit is 0 by default. It can be useful to set this bit when you have fault conditions

that can be corrected without examining the ladder logic. In that case, the operator will be able to clear the fault and restart the processor by cycling power.

Note Correct the cause of the fault before cycling power.

Load Memory Module on Memory Error (S:1/10)

(Not available on MicroLogix) This bit controls the way the processor starts up. If this bit is set and a memory fault is detected when the processor starts up, the

contents of the memory module will be copied to the processor. If bit S:1/10 in the memory module is also set to 1, the processor will go into run mode. This bit is 0 by default.

If this bit is set, the memory module will overwrite the processor memory on powerup.

3-10

Load Memory Module Always (S:1/11)

(Not available on MicroLogix)

This bit controls the way the processor starts up.

If this bit is set when the processor starts up, the contents of the memory module will be

copied to the processor.

If the processor was in run mode or faulted from run mode when the power went down,

the processor will go into run mode.

If the processor was in test or program mode, or faulted from test or program mode,

when the power went down, the processor will go into program mode.

This bit is 0 by default.

If this bit is set, the memory module will overwrite the processor memory on

powerup.

Configuring the SLC 500 CPU and I/O Modules

Load Memory Module and Run (S:1/12)

(This function is not available on MicroLogix controllers; S:1/12 is the Run Always bit.

For more information refer to Appendix A - Programming Reference for Packaged

Controllers in the Instruction Set Reference.)

This bit controls the way the processor starts up.

If this bit is set when the processor starts up, the contents of the memory module will be

copied to the processor, and the processor will go into run mode, regardless of the state

it was in when the power went down. Otherwise, the processor will retain it's memory

and state as it was when power was lost.

This bit is 0 by default.

If this bit is set, the memory module will overwrite the processor memory on

powerup.

3-11

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Watchdog (S:3/8 - S:3/15)

This value controls the time limit (in 10ms ticks) for a processor scan. If a program scan takes longer than the time you configure, a major fault (code 0022) will occur, and the processor will be halted.

You can set the Watchdog Scan Time to any value from 2 (20ms) to 255 (2.55 seconds). The default is 10.

The actual time since the current scan started is stored in the low 8 bits (S:3/0 - S:3/7) of the word when the processor is in run mode.

The bit numbers here are not displayed on the processor status screen—just the word address S:3.

Scan time for a program can vary, particularly if you use JMP and JSR instructions. Setting a low Watchdog Scan Time can halt your processor’s operation.

I/O Slot Enables (S:11, S:12)

3-12

(Not available on MicroLogix) These bits allow you to disable I/O cards. Each bit corresponds to one of the 30

possible slots (S:11/0 represents slot 0 on fixed I/O systems, S:12/15 is not used). When a bit is 1, the corresponding card (if any) is enabled. If a bit is 0, the corresponding card is ignored.

When an output is disabled, it is frozen in it’s current state as long as the processor is in run mode. When the power is cycled, a fault occurs, or another mode is selected, the outputs become 0.

Enabling or disabling a slot can affect machine operation, potentially damaging equipment or injuring personnel.

4 Data Table Addressing and

Editing

PLC-500 A.I. automatically creates and expands data table files while you create and

edit your ladder program. This chapter discusses how to manually manage data table

files using the Memory Map utility.

PLC-500 A.I. contains the following features to make addressing I/O simpler:

• Symbolic Addressing: You can assign symbol names to word or bit addresses,

and use them instead of the address during programming.

• Auto Addressing: The PLC-500 A.I. software can assist you in managing I/O and

memory usage by selecting the next unused I/O word or bit on a particular card, or memory element in a particular file, whenever a new symbol name is used during program development.

• Auto Describe: With this option enabled (it is enabled by default), the instruction

description editor appears any time an undescribed address is used.

• Short Addressing: If you enable short addressing, you can leave out the file

number when addressing one of the default files (files 0 through 7 or 8 depending on your processor). For example, the short address form for address N7:13 is N13.

• Indexed Addressing: The specified address is offset by the value stored in S:24.

• Indirect Addressing: You can substitute a component of a logical address with

the value at another address. (SLC 5/03 OS302 and 5/04 OS401 only)

Note Data Table Files can only be created or deleted while offline.

2. Press [F5] Create. PLC-500 A.I. displays the following prompt.

3. Select Normal or DEBUG (for use with Emulator software). The system asks you

for the address you want to create. (Note: DEBUG files are not downloaded to the processor. They are only for use offline with the emulator.)

4. Type the address you want to add to the data table, and press [Enter].

5. If you entered an address for a new file, the system asks you for an access type for

the file. Unless you want to limit direct access to the file to a single program file, select [F1] Global access.

6. The system asks you to assign a name, with a maximum of 10-characters, to the

new data table file. Type the name, and press [Enter].

7. The system asks you to type a description of the data table file with a maximum of

40-characters. Type the description, and press [Enter]. The new data table file appears in the file list.

Expanding a Data Table File

To expand a data table file:

1. From the Data Table File screen, press [F5] Create. The system asks you if you

want to create a normal data table file or a DEBUG data table file.

2. Select Normal or DEBUG (for use with Emulator software). The system asks you

for the address you want to create. (Note: DEBUG files are not downloaded to the processor. They are only for use offline with the emulator.)

3. Type a new address for the existing data table file, and press [Enter]. The system

will expand the file to include the address you specify. For example, if N12:10 was the highest address in the file, and you entered N12:20, data table file N12 will be expanded to 21 words, so N12:20 is its last address.

Data Table Addressing and Editing

4. The system asks you to assign a name, with a maximum of 10-characters, to the

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Naming and Describing a Data Table File

To describe a data table file, access the Data Table File screen (See page 4-2 for instructions) and highlight the file you want to describe. Press [F4] Name. The system asks you for a file name with a maximum of 10 characters. Type the filename, and press [Enter]. The system asks for a file description with a maximum of 40 characters. Type the description, and press [Enter]. The filename and description appear on the Data Table File screen.

Changing the File Access Mode

The description database uses two file access modes for data table files:

• Global allows access from any program file

• Local allows access from only one program file.

Generally, you should use global access for your files, but there are instances where you may want to limit access to a file. One such instance is when files contain information that is only appropriate to one program file. In this case, you can limit access to prevent accidental overwrites of the data. Another instance is for recipe programming, where there are a multitude of similar activities for the same ladder program; restricting access to critical data files to only those programs that use them prevents confusing the recipe process.

Note The file access mode is not a function of the SLC 500 processor. It is still possible to

overwrite local data table values from other program files by using other software, by using indirect addresses, or by indexed addressing beyond file boundaries.

To change the file access mode:

1. Access the Data Table File screen. (See page 4-2 for instructions.)

2. Highlight the file whose access mode you want to change, and press [F8] Filemod.

If the file was local, the system asks you if you want to switch its access mode to global. Select [F1] Yes or [F5] No. If the file was global, the system asks you if you want to switch its file access to local. Select [F1] Yes or [F5] No.

3. If you select local file access, the system asks you which program file number the

data table file should be local to. Type the file number, and press [Enter].

4-4

Data Table Addressing and Editing

The file modes are maintained in a file with the name PROJECT.ATT, where “project”

is the name of the SLC 500 project. To change all the data table file modes to global,

delete this file.

Note The default data table files (O0 through F8), cannot be made Local. These files are

always Global.

Protecting a Data Table File

Data table file protection is available with any of the SLC 500 processors; however, you

have the most flexibility with SLC 5/03 and 5/04 processors. Three modes of

protection are available: static, constant, and memory module.

• Static. Values in a statically protected data table file can only be changed during

ladder program execution, including online edits. Values cannot be changed by communication channels.

• Constant. No changes can be made to a constantly protected data table file,

whether by communication channels or your ladder program. Input, Output, and Status files cannot be constantly protected.

• Mem-Mod. Memory module protection allows you to autoload your memory

module and preserve retentive data in the protected file. This will only occur if the program in the processor is the same as the program in the memory module. If the programs do not match, all memory module data files are transferred to the processor and bit S:36/10 (Memory Module Data File Overwrite Protection Lost) is set.

Fixed and SLC 5/01 Processors

The Output file is always statically protected. You cannot alter the output data table

file while in the REM Run mode using the communication channels. All other data

table files, however, are unprotected.

4-5

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

SLC 5/02 Processors

You can choose to statically protect your data table files at the time you save your program. When you save your program (refer to Chapter 6 - Creating and Editing Ladder Logic), the following options appear.

Press [F4] File Protection to toggle between:

• Outputs only the Output file is statically protected (default)

• All all data table files are statically protected

• None no data table files are statically protected

SLC 5/03 and 5/04 Processors

You can protect individual data table files when using a SLC 5/03 or 5/04 processor. You cannot write to a protected status file while in the run or test modes. You can, however, clear a processor fault, write a zero to bit S:1/13 (Major Error Bit Halted), or clear words S:5 (minor error bits) and S:6 (Fault Code) while in the fault mode.

Monitoring the Global Status File

SLC 5/04 OS401 or higher processors only

You can use the Global Status File to send a high-speed broadcast to all processors on a network in one token rotation. Using a MSG instruction would require as many MSG instructions and token rotations as there are processors on the network. This is useful for such activities as sending start/stop signals, synchronizing processors, and synchronizing clocks.

4-14

The Global Status File occupies words S2:100 through S2:163 of the Status File and consists of Global Status Words passed from other processors on the DH+ network. Bit S2:34/3 must be set to enable transmitting the Global Status Word. This bit is set to zero by default. When the processor passes the DH+ token to the next node, it will also send the 16-bit Global Status Word. Only the “next” node on the network accepts the token, however, all nodes on the network read the Global Status Word and may save it to memory. To save the Global Status Words received from other processors to memory, bit S2:34/4 must be set. This bit is set to zero by default.

Each processor has a table in memory with as many words in it as there are nodes on the DH+ network. One word of every node’s table is updated each token pass, provided that the GSW Transmit Enable (S2:34/3) and GSW Receive Enable (S2:34/4) bits are set. For more information on network communications, refer to Chapters 15 - 17.

Multipoint Monitoring

(SLC 5/03 OS302, 5/04 OS401, and MicroLogix only) Multipoint monitoring allows you to define a list of bit addresses for monitoring and editing. These addresses need not be contiguous. You can use a multipoint list to:

• change the on/off state of bits

• set and clear forces on I/O points

• define symbols

• write protect a bit

The multipoint list for SLC 5/03 OS302 and 5/04 OS401 processors can contain as many as 32 points. The multipoint list for MicroLogix controllers can contain only 16 points. Two modes are available, Online and Offline. The multipoint display and menus are slightly different between the two modes. The online multipoint list is stored in the processor’s memory and is, therefore, cleared whenever the processor’s memory is cleared. The offline multipoint list is stored in the project file. It is not part of the processor image; however, you can add it to the processor image by copying it to the online multipoint list.

Data Table Addressing and Editing

Selecting a SLC 500 Address or Operand

When you insert or append an instruction into a ladder program, the system asks you to specify addresses for the instruction. For example, the illustration below shows a timer instruction before and after addresses and values are specified.

Before Specifying

For additional information about instruction requirements, use the Instruction Help facility (use the command portal string .UUKI or [Shift-F10]). While programming an instruction, you can press [F10] to get help on that specific instruction.

Addressing Modes

The SLC 500 processor supports a number of different addressing modes.

Logical Addressing

Logical Addresses consist of an alpha-numeric string with punctuation to specify the data location. For instance, N7:50 represents the 51st word in file N7. (Remember, the first element in any file is “0”.)

Indexed Addressing

Indexed Addresses (SLC 5/02, 5/03, 5/04, and MicroLogix processors) consist of a prefix (#) followed by a logical address referred to as a base address. An offset value from the processor status file word S:24 is added to the base address. For example, if S:24 has a value of 12, then the indexed address #N7:10 would actually reference N7:22 in the data table.

Addresses

After Specifying

Addresses

4-29

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

The value in S:24 can be positive or negative. The data table is not automatically expanded to accommodate indexed addresses. For example, if N7 contains 20 elements and S:24 contains 30, #N7:10 refers to an integer outside of N7. This is referred to as crossing a file boundary. Crossing a file boundary is allowed (except with MicroLogix controllers) if the Indexed Addressing File Range status bit (S:2/3) is 1, otherwise, crossing a file boundary results in processor fault 002A.

File instructions also use and modify the value in S:24. Verify that S:24 contains the correct value before using an indexed address; failure to do so could result in unpredictable machine operation with possible damage to equipment and/or injury to personnel.

When a User Error Handler, STI routine, or I/O Interrupt routine, is invoked, the S:24 value is stored, and when the routine ends, the original value is restored. Therefore, you can’t use these routines to set the value in S:24.

Indirect Addressing

SLC 5/03 OS302 and SLC 5/04 OS401 only

Indirect addressing allows you to use a logical address to specify a component of another logical address. The processor uses the value from the substitute address to form the indirect address. The substitute address is enclosed within brackets [ ].For example, if the value in N7:0 is 13, then the indirect address T[N7:0]:0.ACC refers to address T13:0.ACC. Only word addresses can be used to specify an indirect value (not bit or multi-word addresses).

Note Instructions with indirect addresses execute slower than instructions with direct

addresses because the processor has to look up each indirect address.

Allocate addresses in the data table to include any indirect addresses you specify. The data table will not automatically expand to include indirect addresses.

4-30

Data Table Addressing and Editing

When a direct address (logical or indexed) is assigned to an instruction, the data table automatically expands to include that address. (See Appendix C - Data File Organization and Addressing in the Instruction Set Reference for more information on allocating data table addresses.) The following table describes data table allocation for indirect addresses.

If the indirect component refers to then

a file number no data table space will be allocated an element number data table space will be allocated as if element zero was

specified

a subelement number data table space will be allocated as if subelement zero was

specified

a bit number data table space will be allocated as if bit zero was specified

Examples

Indirect Address Memory Allocated

N[N7:1]:8/4 none

T4:[N7:1] T4:0 N20:[N7:1]/4 N20:0/4 N20:8/[N7:1] N20:8/0

The data table will expand to include an address used to specify an indirect address. For example, specifying the indirect address N11:[N22:33]/[N44:55] would cause the data table to expand to include the following addresses.

• N11:0

• N22:33

• N44:55

For more information on Indirect Addressing, refer to Appendix C - Data File Organization and Addressing in the Instruction Set Reference.

Note When converting a program or a block of a program to a processor that does not

support indirect addressing, the indirect addresses will remain and the program will be saved with errors. Edit the program to change the indirect addresses to direct addresses.

4-31

MicroLogix 1000 and PLC-500 A.I. Series Software Reference

Symbolic Addressing

PLC-500 A.I. allows you to assign a symbol name to a word or bit address, and use the symbol instead of the address during programming. A symbol is a description of the data the word or bit address represents, and can be up to 15 characters in length. To create a symbol, simply type a new symbol name in response to a prompt for an address. (See Auto Addressing on page 4-34 for more details.) You can assign symbols to both direct and indirect addresses.

Note The following characters may NOT be used in a symbol name: * ? . / : # $ [

]. Characters from the Extended ASCII character set are also invalid in symbol

names. (These characters are specified by holding down the [Alt] key while typing a number on the numeric keypad.)

Symbol Help

Anywhere the system prompts you for an address, you can obtain symbol help, which allows you to select from a list of existing symbols. Press [Ins] to display the symbol help screen.

4-32

The symbol help screen shows the symbol name, data file type, address type (word or bit) and description text. Position the cursor on a symbol and press [Enter] to select that symbol/address.
