Summary of Changes
Software Revision 1.2
Hardware Changes
Important: Revision 1.2 software cannot be operated on a machine
wired for Revision 1.1 (or earlier) software without this change:
You must move the pressure switch from the port line of the
clutch/brake valve to the pressure line. This is because we changed
the logic of the clutch/brake pressure switch from “cycles with the
clutch/brake valve” to “must be ON to run the press”.
Additional New Features
Category:
For These New Features:
Control Bits
Delayed start (alternate programming of original control bit)
Soft" clutch and brake to provide smoother starts and stops
Valve stems enabled to omit the wiring of unused valvestem feedback
Remote fault reset to clear a C/B software fault from a remote PB
Software microinch mode to select this mode remotely
Use Bits B151/:

Software Revision 1.1
Important: Revision 1.1 software cannot be operated on a machine
wired for Revision 1.0 software without this change:
You must change the type of chain break switch from normally-closedheld-open to normally-open held-closed. This is because we changed the
chain break logic from “input goes ON” for a chain break to “input goes
OFF”. (See wiring drawing sheet 8, module group 4.)
This change remains throughout subsequent software revisions.

Publication 65566.5.1 - October 1996
Overview of the Clutch/Brake Control System
Control by
Redundant Processors
1–3
The clutch/brake control system uses two independent PLC-5/x6
processors (Figure 1.1), such as but not limited to:
• PLC-5/46 processor operating in scanner mode in chassis A
• PLC-5/26 processor operating in adapter mode in chassis B
Both processors monitor all clutch/brake I/O and exchange information
regarding machine status. They are linked by hardwired I/O and a
communication channel so that if one processor detects a condition
different from that detected by the other, its control logic is designed to
declare a fault and turn off all outputs to press valves. The other
processor is designed to follow suit.
Chassis A or B may contain additional optional I/O modules for other
press functions. Otherwise, I/O modules in both chassis are identical.

Overview of the Clutch/Brake Control System
How the Software
Controls Your Press
The clutch/brake control system can control the entire press because
you can add your own ladder logic for other press functions. Factoryprotected logic for control of the clutch/brake mechanism is stored in
locked program files (PF2 and PF16). You store your own clutch/
brake interface logic in an unlocked program file (PF15). Either
processor can use program file (PF3) to call subroutines (PFxx) or to
directly control auxiliary press functions that you program.
Organization of Program Files
We organized selected program files in both PLC-5/x6 processors as
follows to control the clutch/brake and other press functions:
Program File
Description (Processor in Chassis A)
Description (Processor in Chassis B)
PF2 (Locked)
Factoryconfigured Master Control Program
Identical to the processor in chassis A
PF3
Used to program or call subroutines to control
auxiliary press functions, such as automation
valve, die protection, etc.
Optional but available for application
programming, independent of the
processor in chassis A

Used to program the clutch/brake interface
with machine sequencing to customize the
clutch/brake code in PF16
Similar to the processor in chassis A

Protected Memory in
PLC5/x6 Processors
Security
When programmed with either version of Rockwell programming
software, PLC-5/x6 processors provide enhanced security.
Designated program files, such as those storing factory-configured
clutch/brake control logic, are locked at the factory. You can read
them but you cannot:
• edit locked program files of a PLC-5/x6 processor
• restore PLC-5/x6 programs to other PLC-5 processors
Other program files in the PLC-5/x6 processors are available for your
application programming.
Programs written for PLC-5/x6 processors are transferrable between
PLC-5/x6 processors only with the Rockwell software used to write the
original program.
Passwords and Levels of Memory Protection
Either version of Rockwell software and PLC-5/x6 processors provide
four levels of memory protection. The password to the highest level
(including, access to program files PF2 and PF16) is kept confidential at
the factory. We pre-assigned access privileges to other levels. They
include a read-only privilege at the lowest level. You create your own
passwords for the three lower levels.
We show you how to assign privileges and passwords in chapter 5.

Modes of
Control System operation
122451
You select the mode of control system operation with a selector switch.
In accordance with ANSI B11.1 Section 4.12.4.1, the means of selecting
the operational mode must be capable of being fixed by a supervisor.
Typically, this is interpreted as to mean a keyswitch.
This Mode
Lets you:
Off
Disable operation of the clutch/brake control system when not in operation
Inch
Move the press up or down to the desired position with Inch pushbuttons
(or by ladder logic) to set up dies and tooling (not intended for production)
Microinch
Same as Inch but at a slower speed. Requires a separate drive assembly
and operates from a separate set of outputs
Single
Cycle the press through a single uninterrupted stroke (from top to bottom
to top) with RUN buttons, with or without onthehop
Continuous
Run the press with uninterrupted stroking for production operation
Remote
Select Inch, Microinch, Single, Auto Single, or Continuous mode, remotely
Simulate inch and run buttons, and arm for continuous on demand

Off
Prevents energization of clutch/brake outputs.
Inch
Lets the operator jog the press through through successive parts of the cycle by pressing
and releasing the pair of INCH buttons. If INCH buttons are held, the press will stop at
the top of its stroke.
Micro-inch
This mode of operation lets you run your press a low speeds (1 spm typical) for setting
up dies. You must supply a separate drive and clutch/brake assembly to drive the shaft
at low press speeds, bypassing the flywheel.
Singlestroke
Lets the operator jog the press through one complete cycle stopping on top,
by holding both RUN buttons until completion of the down stroke.
Continuous
Lets the operator run the press continuously until stopped by a stopontop command,
or until a fault is detected. The method to start the press is a factory configured option:
• close the ARM CONTINUOUS switch and press both RUN buttons in all active stations
within five seconds.
• hold both RUN buttons for half a stroke until takeover (runon) cams close
(or for 11/2 strokes if so configured).
Remote
Lets you program the selection of these modes remotely:
• inch
• microinch
• single stroke
• automatic single stroke
• continuous
Lets you program automatic press motion with:
• simulate inch buttons
• simulate run buttons
• arm for continuous on demand
Onthehop
Singlestroke
Lets the operator recycle the press without stopping by releasing and pressing both RUN
buttons during a specific portion of the upstroke. (factoryconfigured option)
Stopontop
(cycle stop)
Continuous
Lets the operator stop the press at top of stroke (after the takeover cam signal turns off).
Interrupted stroke
Singlestroke
or Continuous
Lets the operator stop the press quickly by releasing a RUN button during a downstroke.
Antitiedown
All
Prevents the press from starting if the system detects that an operator has tied down one
or more RUN buttons. After all RUN buttons are released, the operator must press both
RUN buttons at a station at the same time. The same applies to the pair of INCH buttons.
Antirepeat
Singlestroke
Limits press operation to a single stroke, even if the operator continues to press both
RUN buttons. The operator must release and press them again to start the next stroke.
Inch
Limits press operation to a single stroke when using a pair of INCH buttons.
Motion detector
Singlestroke
or Continuous
Configurable option designed to detect press motion from a hardware or software input.
Brake Monitor
All
Configurable option designed to prevent restarting the press when the system detects a
faultybrake signal from the brake monitor cam (BCAM) or from a timebased input.

Overview of the Clutch/Brake Control System
Choice of Position
Monitoring Devices
Purchased separately, you have a choice of dual position monitors:
• rotary cam limit switches
• resolvers
• combination of both
If using rotary cam limit switches, we recommend:
• a pair of Allen-Bradley Cat. No. 803-B94 or 803-P94
If using a resolver, we recommend one of these solutions:
• AMCI Series 1700 AMCI Resolver, and Absolute Resolver Input
Module that plugs into the 1771 I/O chassis
• NSD VRE–P062 Resolver and VE–2A Single Turn Converter
(decoder) that connects to a high-speed input module such as a
1771-IBD.
Control System Outputs
System Response Time
The clutch/brake control system is designed with three pairs of
outputs available for your application:
Use these Valve Outputs for these Functions
Notes
clutch
clutch/brake valves
For clutch or clutch/brake valves
auxiliary
auxiliary valves
You can program these outputs in unison
with or in opposition to C/B valve outputs
microinch
separate microinch drive Used in microinch mode only
The worst case time required for the clutch/brake control to respond
to a change of input depends on the sum of these response times:
(excluding scan time for auxiliary press functions that you can
compute from corresponding ladder logic)
Response Time

21
The number of degrees that the shaft continues to rotate, beyond the
moment when the input changes, depends on the speed of rotation.
The greater the speed (strokes per minute), the further the shaft
rotates before a command from the control system is applied. The
response time of 21 ms is represented in degrees of shaft rotation that
increases as press speed increases (Figure 1.6).

Degrees of Shaft Rotation

Important: When estimating the braking distance in degrees of rotation,
you must add the response time of the control system (Figure 1.6) to the
specified downstroke or upstroke braking distance of your press.
If you program additional ladder logic for other press functions in
processor A or B, you will increase the scan time of that processor.
Program scans in both processors are not synchronized, so minimize
the scan time of one processor.
ATTENTION: You are responsible for system response
time. The combination of fast press stroking and additional
program logic could extend the stopping time, resulting in
possible death, personal injury, and/or damage to the press
and/or tangential machinery.
Where fast press stroking and considerable program logic are required
for your application, consider an independent PLC-5 processor for other
press functions.
Internal Timers
The clutch/brake control program contains timers with factory-set presets.
You may change timer presets to time out faster, but never slower than the
factory-set presets. See chapter 4. Examples of internal timers include:

Chapter Objectives
This chapter helps you complete the design of your Clutch/Brake Control
System by specifying design characteristics on a worksheet as follows:
•
•
•
•
•
•
•
•
•
verify your factory-configured options

Define Your Control System Characteristics
2. Assign Valves to
Specific Outputs
Each processor has three pairs of outputs for press valves
(6 outputs per processor, 12 outputs per system). The pairs are:
• Clutch 1 and Clutch 2 (Clutch and Brake)
• Auxiliary 1 and Auxiliary 2
• Micro-inch 1 and Micro-inch 2
Assign your press valves to specific outputs as follows:
If your press has
Then use these outputs
one set of valves for clutch and brake
Clutch 1 and Clutch 2 for both
auxiliary valves for other functions
such as soft" C/B and/or dump valves
Clutch 1 for clutch, Clutch 2 for brake
Auxiliary 1 and Auxiliary 2 for other
one additional set of valves for microinch
Microinch 1 and microinch 2 for microinch
Important: If using dump valves to assist in controlling the brake,
you can program whether dump valves turn ON/OFF in unison with
or opposite to clutch valves. We cover this under Command Bits in
chapter 4.
Record your assignment of control system outputs on the worksheet.
3. Select the Type of
Valve Fault Detection
There are two types of valve fault detection:
• internal – the valve checks itself for failure
• external – the control system checks a valve-actuated switch on the
spool or stem to verify that the valve cycles every stroke
The type of fault detection determines whether you use valve-stem feedback:
If Your Valves Have
This Fault Detection
Then the Valve
And your control system
internal
• closes automatically when it detects a fault
• will NOT open unless both solenoids work in unison
• has NO valvestem switches
omits valvestem feedback
external
• has valvestem switches
• provides an external signal of its valve position
(when valve is open, switch is ON)
must have valvestem feedback
Important: If one or more valves have valve-stem feedback, all
valves must have it or simulate it. We show you how in chapter 3.
Record the type of valve fault detection and valve-stem feedback.
Publication 65566.5.1 - October 1996
Define Your Control System Characteristics
4. Select the Type of
Position Sensor
2–3
The control system uses dual independent position sensors to monitor
the slide position. You select the type of position sensor from:
• dual rotary cam limit switches (RCLS)
• dual resolvers (with RCLSs simulated in ladder logic)
• combination of both
Rotary Cam Limit Switches
These switches monitor the position of the slide by riding rotating
cams. The switches open or close according to the cam geometry that
you can adjust to represent the six rotational zones in the press cycle.
You must use two independent switch assemblies, one wired to
chassis A, the other to chassis B, with these limit switches:
• brake monitor (BCAM)
• takeover (TCAM)
• anti-repeat (ACAM)

1 N.O. contact
(2 switches per system)
If using rotary cam limit switches, record the fact on the worksheet.
We assist you in setting up your rotary cam limit switches in chapter 7.
Resolver
Resolvers monitor the position of the press slide electronically, so are free
from contact failure. We recommend either group of resolver devices:
• AMCI Series 1700 resolver and interface module (for I/O chassis)
• NSD VRE-P062 resolver, VE-2A decoder, and 1771-IBD input module
When using resolvers, you must simulate the action of cam limit
switches with ladder logic. We assist you in doing this in chapter 7.
We reserved slots 0 and 1 of I/O chassis A and B for resolver input
modules. This slot location helps you isolate ac and dc input signals.
If using resolvers, record the brand and model on the worksheet.

5. Record On/Off Positions
of Rotary Cam Limit
Switches
During installation of your rotary cam limit switches, you must set
the on and off positions of these switches (Figure 2.1). Use the
initial on/off positions specified by the press manufacturer.

b. BCAM is On when ACAM is Off.
c. ACAM does not cycle while TCAM is On during upstroke.
ACAM should remain On for the entire stroke except for
an On/Off/On cycle while TCAM is On during upstroke.
The dual sets of contacts need not cycle at the same moment.
An offset of up to 1 second is acceptable. You can reduce this preset.

To customize the wiring drawings to suit your application:
1. Select the modifications that apply to your application from tables
on left-hand pages in this section.
2. Follow the instructions for the modification.
Some modifications require that you write ladder logic to replace
the function of the deleted wiring, or that you wire an input
terminal to a power rail.
3. Observe the corresponding example wiring diagram on the
right-hand page that results from making the modification.
We present instructions according to I/O module group because the
wiring for each I/O module group is presented on a separate drawing
in your set of wiring drawings.

Write Ladder Logic
Chapter Objectives
To help you write ladder logic to customize the operation of your
clutch/brake control system, we present the following information:
•
•
•
•
•
•
•
•
•
•
•
•
overview of memory organization for processors A and B
data files reserved for control system data
how command bits act on control logic in protected memory
select from these command bits
steps to write ladder logic
programming command bits
using fault and prompt bits
exchanging data between processors with the scanner/adapter channel
programming shorter presets for your internal timers
programming press-ready-to-start indicators
programming a brake monitor
programming a variable-speed top stop
Important: We suggest that you study the entire chapter before you
begin writing your logic.
Overview of
Memory Organization
Your clutch/brake control system has dual PLC-5/x6 processors: one in I/O
chassis A, the other in chassis B. Memory organization is similar in both
processors. Program files PF2 and PF16 are factory programmed and password protected for “read only”. You will program your clutch/brake
interface in program file PF15, and your machine-related functions such as
for robotics, lubrication, and die change in pre-assigned subroutine files.
We organized processor memory as follows:
Program File Description (Processor in Chassis A)
Description (Processor in Chassis B)
PF2
Factoryconfigured Master Control Program
(Locked)
Identical to processor in chassis A
PF3
Used to call subroutines to control auxiliary
press functions, such as automation valve,
die protection, robotics, etc.
Optional but available for application
programming, independent of
processor in chassis A

Where you program the clutch/brake
interface with machine sequencing to
customize the clutch/brake code in PF16

Write Ladder Logic
Reserved Program and
Data Files
Allen-Bradley has adopted certain conventions for assigning press-control
functions to specific subroutine files. For standardization, we suggest that
you assign subroutine files and corresponding data files for press-control
functions in addition to the clutch/brake as listed in Appendix E.
We recommend that in program file PF3, you call a subroutine for
each press-control function with Jump to Subroutine, Subroutine,
and Return instructions. We designed the software with this in mind.
Important: For standardization when programming your
press-control requirements, we recommend that you follow the
assigned files as listed in Appendix E.
How Command Bits Act
On Control Logic in
Protected Memory
Command bits, B151/00-29, let you customize the operation of your
clutch/brake control system to include control of press operations beyond
that of the clutch/ brake mechanism alone. Their use is optional. The
clutch/brake control system will control the clutch/brake mechanism
without them. If you selected no command bits for your press application
in chapter 2, skip to Exchanging Data Between Processors for required
programming later in this chapter.
In both processors, your interface program (PF15) contains your
ladder logic that interfaces with the clutch/brake control logic in
protected memory (PF16). You control operations in the
clutch/brake control logic (PF16) by manipulating inputs to that
logic by outputs from your clutch/brake interface logic (PF15). For
example, output command bits x, y, and z from your interface ladder
logic in PF15 are inputs X, Y, and Z to the clutch/brake control logic
in PF16.

Clutch/brake Control
(PF16)
X
--] [------------( )Y
----] [----------( )Z
-----] [---------( )End
Typically, the processors in chassis A and B must see identical
conditions or declare a fault.
Important: We programmed input rungs for command bits at the end
of protected memory in PF16. The command bits used for these inputs
are described in the next table. Most are held ON unless your custom
ladder logic in PF15 turns them OFF. Exceptions are noted in the next
table: they are held OFF unless turned ON.

Select from These
Command Bits
4–3
You may program one or more of the following command bits in
Program File 15 to customize the operation of your press. Your
control system will control the clutch/brake mechanism even if you
program none of them.
Important: Protected memory in PF2 sets these bits to default status.
These bits are turned ON every scan with these exceptions:
Where noted by [ 1 ] below, these bits are turned OFF every scan.

Important: We designed the clutch/brake code in PF16 with the
requirement that you must program most of the command bits with
nearly identical logic and hardware conditions for processors A and B.
The following table designates which command bits do NOT have that
requirement:

Write Ladder Logic
Steps to Write
Ladder Logic
4–5
Follow these guidelines when writing ladder logic for your C/B
interface in PF15. We present programming examples afterwards.
1. Install your programming software on your hard drive. Use
instructions in the manual that accompanied your software.
2. Execute the following procedure to install program files onto
your hard drive (from the diskette in your Application Package).
a.
Insert the diskette into drive A.
b.
Change to “a” drive.
c.
To install program files: at the “a” prompt, type Install C:
If using 6200 Software, installs to C:\IPDS\ARCH\PLC5
If using AI5 software, installs to C:\PLC5\PROGS
3. Rename our program files only if using AI5 software as follows:
(If using 6200 series software, skip this step. You can download a
PLC-5/86 program to a PLC-5/26 or -5/46 processor.)
If Processor A Make This the By Renaming If Processor B Make This the By Renaming
Is This Type:

n/a
Important: With AI5 software, you can download a program
file of designated type only to that type of processor. Select the
program for your designated processor and rename it so you can
download and view the program with comments and symbols.
4. List all operations that you must program, and assign them to:
your interface program file (PF15)
main program file (PF3) We do NOT provide examples for this.
subroutines to PF3 We do NOT provide examples for this.
5. Identify and map the program and data files that we provide (see
appendix E) that your application requires.
6. For clutch/brake logic, review programming examples and commandbit descriptions to be sure that you understand associated logic.
7. Write your own ladder logic. If adding other press-control functions,
use the pre-assigned subroutines. Attention: Be sure to program the
scanning of your subroutines in the correct sequence. Otherwise,
possible unexpected motion could cause damage, injury, or death.
8. Thoroughly check your ladder logic, data and I/O addresses.
9. Check your ladder logic against the worksheet in chapter 2 to
verify that you programmed all required functions.

We present programming examples for command bits B151/03-B151/29.
ATTENTION: You are responsible for your own application
logic. If using our examples, do so only after modifying them
to suit your application. Direct use or misapplication of these
examples could result in unexpected machine motion with

To start press motion, we recommend that you use the following bits:
• B151/03 – permit cycle start
• B151/04 – permit run
• B151/05 – permit downstroke (or delayed start)

Example of the Permit Cycle Start Command B151/03
Use this command in single or continuous mode to ensure that the
piece is in place before pressing Run buttons to start the press.
Include B160/60 if you want to start only from the near-top position.

Soft" Clutch and Brake
A “soft” clutch/brake provides smoother starting and stopping of
press motion. The clutch and brake are activated with a 2-step valve
sequence using auxiliary pressure-relief valves in series with the
main clutch/brake valves. You preset auxiliary-valve time delays to:
• provide a brief interval of pressure-relieved slip action
• turn auxiliary valves ON or OFF for full pressure at time-out
You select time-delay presets in the range of 0.1 – 1.0 seconds
according to the speed of the press, as shown in the following
example timing diagram:
Engage clutch
to start the press
Disengage clutch and
engage brake
to stop the press

//

To program a soft clutch and brake, use control bits
B151/16, 17, 19, and 22.
Important: The sequence and logic of these bits are application
dependent. For example:

When B151/27 is turned ON, it starts a 5-minute one-shot timed interval
in which your logic must simulate pressing run buttons by setting
B151/25. Use B151/27 under these conditions:
• completely automated press with run buttons ignored
• remote continuous mode
(bit 14 = ON and manual selector switch in remote mode)

Exchanging Data
Between Processors
PLC-5 processors have a unique feature that transfers data between
processors in a scanner mode/adapter mode configuration. The
clutch/brake software uses channel 1B and rack address 02 on the
remote I/O network to transfer required information between
processors. The C/B software configures the processor in chassis A
for scanner mode and the processor in chassis B for adapter mode.
Important: For the adapter-mode processor (chassis B), we have
changed the adapter-mode configuration of channel 1B from rack 03
(default) to rack 02. For more information, refer to the documentation
that accompanied your programming software.
ATTENTION: If your application requires additional I/O racks
on this network, use rack addresses other than rack 02, and take
care not to excessively load the network and extend system
response time. Either could cause unpredictable machine
response with possible personal injury and/or equipment damage.
If you want to transfer discrete data bits between processors in chassis
A and B, we reserved one I/O image table word (O:27) for you to use.
The processors exchange information as follows:
• an output in processor A = an input in processor B
(O:027/03 in processor A = I:027/03 in processor B)
• an input in processor A = an output in processor B
(I:027/03 in processor A = O:027/03 in processor B)
Publication 65566.5.1 - October 1996
Write Ladder Logic
4–19
For example, if processor A monitors position with resolver inputs
and processor B controls all pilot lights for press operational status,
processor A could transmit the status of top dead center to processor B
as follows (Figure 4.23):

Using
Fault and Prompt Bits
We designed internal diagnostics such that when control logic detects
fault conditions or other conditions worthy of attention, it sets a
corresponding bit in either of two bit files:
• fault bits in B168/0-B168/159
• prompt bits in B169/0-B169/80
We provide you with a look-up table that states the type of fault and
suggests what to do to correct it. Refer to Appendix E and the
Operators Guide for identical look-up tables.
We suggest that you design a method to monitor these bits and
display the triggered condition, depending on the type of operator
interface you use. The following logic (Figure 4.24) generates a
BCD fault number whenever control logic sets a fault or prompt bit:

Programming Shorter
Presets for Your
Internal Timers
If you need to shorten presets of internal timers, do this in program
file 15. For each timer that you want to change, add a rung as
follows (Figure 4.25):
• input instruction = GEQ (greater than or equal to)
Source A is the address of the timer whose preset you want to change.
Source B is the new preset (base = .01 sec)
• output instruction = Bit address associated with the timer
For example, the following example shortens the timeout value for
Clutch A Failed to Turn OFF from 1 second to 1/2 second.

logic in program file PF15 that indicates when the clutch/brake control
modes are ready to start (Figure 4.26). Examine the following “ready”

Programming a
Brake Monitor
(patent pending)
The brake monitor program is designed to monitor and compute
stopping time. This example program is contained in a selectable
timed interrupt (STI) subroutine with a 2 ms interrupt. The program
detects stopping time by counting the number of interrupts from
when the brake is applied until press motion stops. The accuracy
is" one interrupt period ("2 ms in this example).
Selecting the Interrupt Period
The example program scan jumps to the STI subroutine every interrupt
period, executes the subroutine, returns to the main program, and
continues executing the main program until interrupted again.

Write Ladder Logic
4–23
The time required to execute the example STI program (Figure 4.27)
is about 1/2 ms, so we suggest an STI interrupt interval of about 2
ms. The shorter you make the STI interrupt interval to increase the
accuracy of the brake monitor, the less time remains to execute the
main program so its overall execution time increases.
The program uses the following words:

Programming a
Variablespeed Top Stop
The purpose of the variable-speed top stop program is to make the
press stop at the top when commanded, regardless of press speed.
Requirements of this program are the following:
• You must use a resolver as a position monitoring device
• Your program must simulate the action of rotary cam limit switches
• Your program should adjust the TCAM setting only during
downstroke. Shifting the TCAM in any other zone of the press
cycle may trigger a software cam-transition fault.
In the following example program (Figure 4.28), N123:36 holds the
press speed which is buffered once per stroke at 90o. The LES and GTR
instructions in the TCAM rung are used for backing the TCAM OFF
position from 340 to 300o for increasing press speeds of 10 to 26 SPM.

Assigning Passwords to Your
Program and Data Files
Chapter Objectives
Program and data files of PLC-5/x6 processors can be protected from
unauthorized access by assigning privileges and a password to each
of four privilege classes. We have assigned these at the factory.
This chapter explains how:
•
•
•
•
What Can Privilege
Classes Protect?
we assigned privileges to privilege classes
we restricted access to certain program and data files
you assign your own passwords to privilege classes 2-4
you gain access to protected memory files
Privilege classes can control read/write access to:
• data files
• program files
• communication channels
They can also protect the control system from unauthorized changes
such as:
•
•
•
•
modifying privileges
uploading/downloading processor memory
forcing bits on/off
changing processor mode

Assigning Passwords to Your Program and Data Files
How We Assigned
Privileges to
Privilege Classes
The software is factory–configured for access privileges for security.
We assigned:
• privileges to privilege classes
• read or read/write access to program and data files
Class 1 has all privileges. The password to class 1 is held confidential
at the factory. We assigned privileges to classes 2-4 at the factory, and
withheld the privilege to modify privileges from these classes.
Important: As a result of withholding the capability to modify
privileges in classes 2-4, you cannot modify privileges on the
following screens:
• Privilege screen
• Data File Privilege screen
• Program File Privilege screen
Since you cannot modify privileges, our purpose in describing access
to these screens is informational: to show you how we assigned
privileges. We did this to protect the proprietary clutch/brake control
program and data files.
Important: With this privilege structure, you may create program and
data files for your own ladder logic. You will have RW access to them.
Privilege Classes
We assigned combinations of privileges to each of four different classes
from all privileges (class 1) to fewest privileges (class 4). To view the
Privilege screen that allocates privileges, type Alt P from any screen.
You get the Privilege Class Information screen. We assigned the following
privileges to classes 1-4 at the factory. (X = privilege allowed)

Communication Channel Privileges
We assigned class 4 as the default privilege class for channel
communication, and R (read only) or RW (read/write) privileges to
classes 1-4 for controlling channel access.
Important: Default class privileges cannot be assigned to scanner or
adapter channels; just to channel 0 or any channel configured for a DH+
network (for communication with a programming terminal).
To view the Channel Privileges screen that allocates these privileges,
follow this procedure for 6200 series software (the procedure for AI5
software would be similar):
1. Start at the Main Menu.
2. Press [F7] - General Utility.

Assigning Passwords to Your Program and Data Files
Assigning Passwords
to Classes
You can assign a password to each of classes 2, 3, and 4. We suggest
that you distribute passwords within your organization based on the:
• access that each password allows
• responsibilities of password users within your organization
Important: Only class 1 privileges include modifying privileges of
other classes. The password for class 1 is maintained confidential at the
factory. Neither a customer nor any authorized Allen-Bradley
sales/service representative can obtain this password. This lets us
maintain protection of the factory-configured clutch/brake code.
We assigned the password [RETURN] to classes 2-4 at the factory.
You can change this password with the following procedure for 6200
series software (the procedure for AI5 software would be similar):
1. Start at the Program Directory for Processor screen.
2. Press [F7] – General Utility
The system displays a new set of function keys.
3. Press [F5] – Privileges
The system displays the Privilege Class Information screen.
4. Press [F1] – Modify Password to assign a password to each class.
The system displays the Modify Privilege Class Password window.
5. For each class you want to use, type
class name (for example, Class 2)
old password (if one exists)
new password (8 characters max, A-z, 0-9, and _)
verify new password
Gaining Access to
Protected Memory Files
2.
Repeat steps 2 and 3 as needed for the other classes (Class 3-4).
3.
When finished assigning passwords, press [ESC].
The system displays the General Utility screen.
When you first attempt to edit program or data files, you will be
denied access. You must establish yourself as a class 2 or class 3
user to edit program and data files respectively for those classes.
To do so, follow this procedure for 6200 series software
(the procedure for AI5 software would be similar):
1. From any screen below the Menu (the highest level) screen,
press these keys at the same time: [Alt] P
You get the Select New Privilege Class window.
2. Type your privilege class name (class 2 or class 3) and press [Enter].
The cursor moves to the password entry field.
3. Type your password for that privilege class and press [Enter].
Now, you can access all functions available for that class.

Convert Controller OK
Relay Contacts
from N.O. to N.C.
The default mode of 700P relay contacts as shipped in this package is
normally open (N.O.). You must convert the contacts to the normally
closed (N.C.) mode. To do this, remove each of the relay cartridges
and flip the screw terminals to the N.C. position as follows:
1. Remove the coverplate by unscrewing the two captive screws.
2. Remove the red crossbar by unscrewing its captive screw.
3. Remove each relay cartridge from the housing by inserting a
screwdriver blade under a screw-terminal pressure plate and
prying out the cartridge.
4. On the relay cartridge, locate the screw terminals and corresponding
contact–mode symbols –| |– for N.O. and –|/|– for N.C.
5. To convert the contacts from N.O. to N.C. mode:
A. Unscrew the screw terminals 2 turns.
B. Flip each of the screw terminals from the –| |– (N.O.) position
to the –|/|– (N.C.) position.
6. Insert the relay cartridges into the case so the screw terminals
(now in the N.C. position) face front and are accessible.
7. Reassemble the red crossbar and coverplate, and securely tighten
the captive screws.
For additional information, refer to the Instruction Sheet that
accompanied the 700P relay.

set up your position monitoring (RCLS) devices.
read status bits in ladder logic to indicate shaft position
use transition fault bits to stop the press
simulate RCLSs with ladder logic
troubleshoot the setup of your RCLSs
The control system can monitor the rotational position of the press
stroke with either of these position-monitoring devices:
• dual assemblies containing rotary cam limit switches
• dual resolvers that require ladder logic to simulate cam limit switches
Important: With either method, you must use dual independent
positional inputs with the same settings so that:
• brake-monitor contacts must close at a point that indicates unsafe
brake wear, and open in the near-bottom zone after the take-over
contacts close
• take-over contacts must close after the press has closed in the nearbottom zone and open at a point that allows the press to stop at the top
• anti-repeat contacts open during mid-upstroke for at least 75ms.
Position-monitor inputs should operate as follows (Table 7.A):

Set Up or Simulate Rotary Cam Limit Switches
Important: Figure 7.1 shows relationships required by control system
software. To determine exact settings for actual or simulated limit
switches, refer to recommendations provided by the press manufacturer.
Important: Any variation from this scheme will cause one or more
transition faults where the software is designed to shut down the system.
You can vary the ON/OFF times, but not the sequence nor overlap of
signals. This is particularly important during start up. If necessary, refer
to Troubleshooting the Setup of Your Position Monitoring Devices at the
end of this chapter.

delete the motion detector switch (I/O module group 2, Figure 3.4
or 3.16) and do NOT write ladder logic for motion detection with
a resolver input (Figure 4.10).
Important: To set up your real or simulated ACAM, BCAM, and
TCAM on/off positions according to Figure 7.1 and Table 7.B, go

Set Up or Simulate Rotary Cam Limit Switches
Setup If Using Rotary Cam
Limit Switches
(omit if using only resolvers)
If using rotary cam limit switches, follow these steps:
1. Set up the cam angles for each RCLS switch assembly as described
above. Use on/off settings recommended by the press manufacturer.
Important: Mount these assemblies on opposite ends of the crankshaft
that drives the slide so a mismatch will occur if the crankshaft breaks.
2. Wire one assembly to the 1771-ID16 input module in module group 2,
chassis A. Repeat for chassis B. Refer to Wiring Drawings, sheet 6.
3. The ladder logic for RCLS is included in the clutch/brake code,
stored in protected memory.
Some applications combine one RCLS assembly with one resolver.
If this applies to your application, go to the next section to set up the
resolver. If not using resolvers, ignore the remainder of this chapter
because resolvers do not apply to your application.
Setup If Using Resolvers
(omit if using only RCLSs)
If using rotary cam limit switches, follow these steps:
• AMCI resolver connected to an AMCI interface module (Figure 7.3)
• NSD resolver, decoder, and 1771-IBD input module (Figure 7.4)
Follow these steps as applicable:
1. Install resolvers, one on each end of the crankshaft that drives the
slide, so they can detect crankshaft breakage. The same applies
to a resolver-RCLS combination. Refer to installation
instructions provided by the resolver manufacturer.
2. Install a resolver input module into module group 0 and/or 1 of an
I/O chassis. Use module group 0 for a 1-slot input module, or
module groups 0 and 1 for a 2-slot input module.
If using a pair of resolvers, repeat for the other I/O chassis. Refer
to installation instructions provided by the manufacturer of the
resolver input module.
3. Wire the resolver, converter module (if applicable), and input
module for the respective I/O chassis. Refer to wiring instructions
provided by the manufacturer.

4. Repeat step 3 if using dual resolvers.
5. For one or both I/O chassis with a resolver input, remove RCLSs
from circuit wiring by jumpering RCLS inputs to respective
power rails. For instructions to do this, refer to wiring
customization instructions, Module Group 2 (sheet 2) in chapter 3
of this manual.
6. Study the RCLS operation shown in Figure 7.1 and Table 7.B.
You will need to simulate RCLS operation with ladder logic.
We show you how in the next section.
Ladder Logic to Simulate
Rotary Cam Limit
Switches
If using resolver inputs, you must program all three of the following
command bits to simulate rotary cam limit switches shown in Figure 7.1:

Set Up or Simulate Rotary Cam Limit Switches
We present ladder logic to simulate rotary cam limit switches (Figure 7.5).
Use software bits TCAM (B151/00), BCAM (B151/01), and ACAM
(B151/02) to simulate hardware cams when using resolver or encoder
inputs. (We assume that the resolver module is in slot 0 at address I:000.)

If NOT using anti-backlash couplings and you experience reverse-motion
faults (Faults 033 and 113) due to gear chatter, you may need to modify
your ladder logic to shift cam turn ON and turn OFF positions back about
5o instantly at each transition to compensate for gear chatter (Figure 7.6).

How Bits Indicate
Shaft Position
The software sets bits to indicate which of six zones the shaft is
rotating through during a press stroke.
Important: The software reads these zones according to the on/off
positions of ACAM, BCAM, and TCAM switches that you set
(Figure 7.1) mechanically for hardware switches or that the software
reads from resolver inputs if using resolvers to simulate your RCLSs.
The zones and corresponding indicator bits in bit file B160 are
shown in the following table and in Figure 7.7.
While the shaft is in this zone:

How Transition Faults
Stop the Press
7–9
The software is designed to fault when it sees conditions other than
the correct progression of these three rotational zones during a press
stroke:
• Top zone
• Downstroke
• Upstroke
Important: The software reads these zones according to the on/off
positions of ACAM, BCAM, and TCAM switches that you set
(Figure 7.1) mechanically for hardware switches or that the
software reads from resolver inputs if using resolvers to simulate
your RCLSs.
During each stroke, the rotary cam limit switches must cycle as
follows (linear representation of Figure 7.1):
Near Top Zone

* BCAM and TCAM can transition within the
same scan or overlap their On states.
When the software detects any one of the following fault conditions,
it is designed to turn outputs off and set the corresponding fault bit in
B168:
When the software
detects this condition:
It turns outputs Off and sets and this fault bit for

Important: For suggestions on troubleshooting your position
monitoring devices, continue to the next section. For the complete
listing of fault codes, refer to appendix C, Fault Codes and Operator
Prompts.

Troubleshoot the Setup of
Your Position Monitoring
Devices
The processor monitors signals from your position monitoring
devices to ensure that the motion:
• is in the forward direction
• progresses through the correct sequence of real or simulated cams
- downstroke
- upstroke
- near top
When the processor detects a malfunction in the operation of
position monitoring devices, it faults and sets one or more of the
following fault bits to help you troubleshoot the fault.
We recommend that you program a method to display bit numbers of
detected faults. Then, you can respond quickly by looking them up
in the following tables (taken from appendix C):

Dynamic Tests of
Operating Modes
This section tests ladder logic in PF15 for press operation in these modes:
• inch
• single-stroke
• continuous, started by arm-continuous or stroke-and-a-half
Important: We assume that you have downloaded your ladder programs
with 6200 Software (Revision 4.4 or later) into processors A and B.
Important: If the press control system faults or does not operate as
expected in this procedure, read the resulting fault or prompt bit with
your programming terminal and refer to Appendix C for:
• fault codes in bit file B168 for troubleshooting
• prompts in bit file B169 for operating the press
Important: The software must see real or simulated position monitor
signals as described in chapter 7. Otherwise, one or more transition
faults are designed to shut down the system. You can vary the ON/OFF
times, but not the sequence nor overlap of signals. This is particularly
important during start up. Fault bits B168/026-033 and B168/106-113
indicate which position monitor signals are missing or out of sequence.
Test dynamic press operation with the following procedures:
Inch Mode
1. Switch both processors to run mode.
2. Power up the system by pressing the Control Rest and
Clutch/Brake Power Reset buttons.
3. Visually and with a voltmeter, verify that seal relays and CRM
relays are energized.
4. Place the mode selector switch in inch mode.
5. Concurrently, press and hold both Inch buttons.
6. Observe that the press cycles and stops on top.
7. Release the Inch buttons and press again for 1-2 seconds.

Single Stroke Mode
Single stroke mode is designed to stroke the press once, from top to
bottom to top, with the concurrent use of all active run buttons.
Once the press reaches the takeover cam (TCAM), operators can
release Run buttons without stopping the press it continues to the
near-top position.
During downstroke, releasing a Run button stops the press
(Figure A.2). To restart the press, press the Run buttons.
Once the press reaches the takeover cam, the press continues
automatically through the upstroke (Figure A.3).
If you purchased software with on-the-hop, you can start another
cycle without stopping the press if you release all Run buttons.
Then, press and hold Run buttons during the upstroke.

WARNING: If the press coasted past
the neartop position while braking,
the brake is faulty and hazardous.
Repair it immediately.
NOTE: The press continues automatically through upstroke, then stops. If your software includes onthehop,
you can start another cycle without stopping at the top. Do this by releasing, then pressing and holding all Run
buttons during upstroke.

Description of Operating Modes
Continuous Mode
When you want to run your press continuously, ready the press as
follows for starting from any position in the press cycle:
• select continuous mode
• press the arm continuous button (Figure A.4) if you have this feature
• press all active Run buttons within 5 seconds (within the preset time)
In first downstroke, releasing a Run button stops the press (Figure A.5).
If the slide has not entered the upstroke zone, you can resume
downstroke within 5 seconds of pressing the Arm Continuous button.
(The Arm Continuous preset could be less than 5 seconds.)
After 5 seconds (the press is stopped), you must restart continuous
mode with the arming sequence.
If the slide entered the upstroke zone the first time and your press
does NOT have stroke-and-a-half (Figure A.6):
• when both TCAMs come on, you may release a Run button and
the press will continue stroking
If the press is configured for stroke-and-a-half:
• continue holding the Run buttons until the press runs through
downstroke a second time
• releasing a Run button early in downstroke stops the press,
and first downstroke conditions apply
• releasing a Run button during first upstroke stops the press
when it reaches the top
Once in continuous stroking operation, the press stops at the next near-top
position whenever it receives a stop-on-top command (Figure A.7).
However, the press stops immediately whenever:
• either processor detects a trip or stop condition
• a required condition or command bit is removed
• an operator presses the E-stop button

Feedback Timing Diagrams
Timing Diagrams for
Control System Feedback
We define the controller’s feedback response time for these signals:
• triac and valve-stem feedback
(where valve-stem feedback pertains to main, auxiliary,
and/or micro-inch valves with external fault detection)
• motion detector feedback
When PLC-5/x6 processors command triacs ON or OFF, they check
that feedback signals (triac, valve stem, and motion detector) have
turned ON or OFF in the order shown and within the times shown.

signal:

If and when a PLC-5/x6 processor detects that a triac or feedback
signal has not turned ON or OFF within the times shown, it trips
seal relay output to remove power from the wiring arm of
1771-OD16 output module.
If your main valves have external fault-detection with valve-stem
switches and you configured for valve-stem feedback, you have two
options for the other solenoid valve inputs:
• they also must have external valve-stem switches and feedback, or
• if they have internal fault detection, you must simulate external
valve-stem feedback for them (See wiring drawings 8 and 9)

Troubleshooting
with Fault Codes
Whenever a PLC-5/x6 processor detects a fault, it sets a corresponding
bit Bit File 168 in the data table. We list the conditions that for which the
software is designed to detect and signal a fault.
We recommend that you program a method to display bit numbers of
detected faults. Then, you can respond quickly by looking them up
in the following table.

Prompts for
Operating the Press
Whenever a PLC-5/x6 processor detects conditions worthy of a
prompt, it sets corresponding bits in Bit File 169 in the data table.
We list conditions for which the software is designed to detect and
signal a prompt.
We recommend that you program a method to display bit numbers of
detected prompt conditions. Then, you can respond quickly by
looking them up in the following table.

Troubleshooting with Fault Codes, Operator Prompts, and Snapshot Status Bits
Troubleshooting with
Snapshot Status Bits
C–9
The primary means of troubleshooting the clutch/brake control
system is by means of reading fault codes and operator prompts as
presented earlier in this appendix or in the Operator’s Guide,
publication 6556-6.9.1 for PLC processors.
We present the following troubleshooting strategy as an alternative.
Whenever the processors turn off outputs to the main clutch/brake valves
such as due to detecting a fault, the control program takes a snapshot of
the bit logic controlling the press the instant the outputs are turned off.
You can use this information to troubleshoot the cause of the shutdown.
Do this by comparing the status of the snapshot bits with what the status
should have been according to your ladder logic. Start at the last rung
controlling main valve outputs and work backwards until you find all
discrepancies.
The snapshot status of bit logic is stored in file N167:21 as follows:
(The processor substitutes actual status for illustrated bit status 0000.)

What is the Program Scan?
The program scan is the mechanism by which the processor operates.
It is sequential, occurring as fast as 100 times per second.
Here is what the processor does during the program scan (Figure F.1):
Figure F.1
The program scan lets the processor monitor inputs and control
outputs based on decisions programmed by your ladder logic.

Programming Considerations for PLC-5 Processors
How the Processor Scans the Program
The Processor:
1. Monitors Inputs
Monitors the status of input devices by means of input modules.
(The off/on or analog signal of each input appears as a
corresponding 0/1 or BCD bit pattern in the input image table.)
2. Controls Outputs
Controls the status of output devices by means of output modules.
(Sets outputs to an off/on or analog value according to the 0/1 or
BCD bit pattern stored in the output image table for the
corresponding output device.)
3. Executes Ladder Logic
Manipulates data, makes decisions, and/or controls outputs based
on the status of inputs according to your ladder logic instructions.

Instructions
Each instruction contributes a small portion of time to the program
scan. The processor operates on some instructions very quickly, but
takes longer operating on others. Whether the instruction is true or
false also affects instruction execution time (Table F.A).

How to Program
a Faster Response
Here are some suggestions for programming a faster response:
•
•
•
•
program a faster response with special instructions
scan logic only when needed with program control instructions
use single transfer for up to 16 bits (one word) at a time per rung
other considerations
Program a Faster Response with Special Instructions
Rather then trying to minimize program scan time, consider
responding faster with special programming techniques such as:
• program critical inputs and outputs with Immediate Input (IIN)
and Immediate Output (IOT) instructions where the processor
interrupts the program scan to immediately monitor the subject
input or control the subject output each time it scans these
instructions in your ladder logic
• program critical logic with a Selectable Timed Interrupt (STI) file
where the processor interrupts and suspends the normal program scan
at periodic intervals to scan this subroutine. You preset the interval.
With either technique, the processor suspends the program scan while
executing each of these instructions. The resulting program scan is
longer but the processor responds more quickly where/when needed.
Publication 65566.5.1 - October 1996
F–6
Programming Considerations for PLC-5 Processors
Scan Logic Only When Needed
Use program control instructions to reduce program scan time with
these techniques:
• program a jump forward (or back) to avoid scanning portions of your
ladder logic not required under certain programmed conditions
• program a jump to a subroutine (and a return) when you require
intermittent use of a block of ladder logic. The processor scans it
only when needed
Use Single Transfer When Possible
When transferring data between the processor and I/O modules, the
use of single transfer programming is faster than block transfer for
up to 1-word transfers per rung, even if you add extra rungs for
transferring more words.
Other Considerations
Other considerations for a faster program scan are:
•
•
•
•
•
•
•
•
•
•
Using Subroutines
select a faster processor
dedicate an additional processor to critical functions
put critical I/0 in the local I/O chassis rather than in a remote I/0 chassis
minimize the use of remote I/O chassis
minimize the queuing of block transfer instructions
put most frequently accessed data in lower file addresses
(under word 254)
minimize the number of and size of gaps between program file numbers
use integer data rather than floating-point data
use direct addressing
select faster instructions
(arithmetic instructions are faster than compute)
What Are Subroutines?
A subroutine is a block of ladder logic stored in a separate program
file. Generally, it performs a specific function independently. The
use of subroutines helps you:
•
•
•
•
Publication 65566.5.1 - October 1996
simplify your ladder logic
subdivide it into independent functions for custom re-engineering
organize it for easier troubleshooting
save scan time
Programming Considerations for PLC-5 Processors
F–7
How Subroutines Are Scanned
Subroutines are accessed from your main program file or from other
subroutines (nested) by means of these instructions (Figure F.2):
• Jump To Subroutine (JSR) – located anywhere in your ladder logic
• Subroutine (SBR) – the first instruction in the subroutine file and
the target of the JSR instruction (directs the processor scan to the
subject subroutine)
• Return (RET) – returns the processor scan to the rung
immediately following the originating JSR instruction

With subroutine programming, you can:
• update critical I/O within the subroutine with immediate I/O instructions
• pass data into and out of a subroutine
Using Immediate I/O Instructions
Immediate I/O instructions are output instructions that, when
enabled, interrupt the program scan to update a specified word of I/O
image table. You would program them immediately ahead of rungs
that examine I/O that are critical to the subroutine. Otherwise, all
I/O image tables are updated only after the processor has completed
scanning the main program and all enabled subroutines.
This instruction,
when enabled, updates:
For the local chassis, the processor:
Immediate Input (IIN)
a word of input image bits sets input image bits to the current
states of inputs before continuing the
program scan
updates the input image with the latest
input states from the remote I/O buffer
(from the most recent remote I/O scan)
Immediate Output (IOT)
an I/O group of outputs
updates the remote I/O buffer with the
current states of the output image bits
(makes these states immediately
available for the next remote I/O scan)
sets outputs to the current states of
output image bits before continuing the
program scan
For a remote chassis, the processor:
Passing Data Into and Out of a Subroutine
The jump-to-subroutine instruction JSR and return instruction RET
let you pass data to and receive data from a subroutine. You can pass
integer or floating-point numbers (program constants) or designate
addresses to/from which integer or floating-point numbers
(variables) can be passed. Examples of passing data include:
• pass variables to the subroutine for mathematical computations,
and return the result for use in the main program
• pass presets to a generic subroutine for multiple recipe operations
This instruction
lets you:
Jumptosubroutine pass Input Parameters
to the subroutine
(JSR)
by specifying in the instruction:
• integer or floatingpoint constants
• addresses in the main program
from which parameter are passed
receive Return Parameters • addresses in the main program
from the subroutine
to which parameters are returned
Subroutine (SBR)
store Input Parameters
• storage addresses in the subroutine
Return (RET)
return parameters
to the main program
• addresses in the subroutine
from which parameters are returned

Programming Considerations for PLC-5 Processors
Working With Data
Understanding the types of data that your processor handles and how
your processor stores them may help you:
• conserve memory
• achieve a faster processor data scan
Types of Data
The types of data that your processor handles depend on the processor,
but essentially falls into three categories: bit, word, and element.
Data are stored in files, which are blocks of data of similar type.
Some types of data can be stored in more than one type of file.
Each type of file has an ID letter to identify it in an address.
Type of Data
Description
Type of File
File ID
bit
smallest unit of data: 0/1, on/off, set/reset
bit
I/O image
B
I or O
word
16 bits: can represent a numeric value,
such as with binary coded decimal (BCD)
For example: 0000 0000 0000 0110 = 6
I/O image
status
integer
I or O
S
N
element
a multiple number of words
For example: timer element = 3 words
(preset, accumulated, control/status bits)
timer 1
counter 1
control 1
T
C
R
1 Each
timer, counter, or control element uses three words
Addressing Your Data
Logical address formats (Figure F.4) vary depending on the type of
data. Addresses contain these characters:
•
•
•
•
file type (ID)
file number
delimiter to separate address numbers
number (location) of the structure, word, bit, and/or I/O hardware

Creating Data Storage Files
You create data storage files in two ways:
• by directly creating data storage files
• each time you assign an address to an instruction
Good programming techniques suggest that you keep data storage
areas as small as possible to minimize scan time and avoid wasting
memory storage.
Directly Creating Data Storage Files
You create data storage files with your programming terminal by
entering the file address of the highest numbered element that you
want in the file.
For example: If you create a file by entering the address N7:9, the
processor allocates to that address all words (or elements) from that
address down to zero (10 words) or down to the next lower assigned
address. If the next lower assigned address was N7:3, your file at
address N7:9 would include six words down to N7:3 (Figure F.5).
Figure F.5
How the Processor Allocates Data Storage
When You Create a File or Assign an Address
File N7
File N7
N7:9
N7:9
N7:3
0
If there is no other address for File N7,
assigning an address of N7:9 creates a
10word file.
0
If you previously created File N7:3,
assigning an address of N7:9 creates a
6word file down to word 3.
Data Storage Created by Assigning Addresses
When you assign an address to an instruction, the processor allocates
memory storage in a data file. The processor creates the data file
automatically. The size of the file is equal to the number of elements,
words, or bits from the assigned address down to zero or down to the
next lower assigned address.
Publication 65566.5.1 - October 1996
F–12
Programming Considerations for PLC-5 Processors
For example, if your first assigned timer in your program has the
address T4:99, the processor allocates storage for timers T4:99 down
to T4:0 whether you use them or not. Since each timer address uses
three words (timers are 3-word elements), your timer address of
T4:99 has created a 300 word data storage file.
As another example: if you assign the address N7:9 to store a word
(or element), the processor opens a file from that address down to
zero or down to the next lower assigned address. If the next lower
address was N7:3, address N7:9 would include all words down to
N7:3 (Figure F.5).
For further information, refer to either of these programming manuals:
• PLC-5 Programming Software, Instruction Set Reference,
