OS Loader

The OS Loader: At a Glance

Introduction

This software is used to update the operating system on the TSX Micro and TSX

Premium PLCs by a download via the terminal port.

It also gives the option of reinstalling a previous version of the OS.

The functions of The OS Loader is used:

the OS Loader

l to display the OS version installed on the PLC,

l to download the operating system into a PLC memory system.

CAUTION

The download operation includes a delicate phase during which any

PLC power outage is likely to render it unusable.

Failure to observe this precaution can result in injury or equip-

ment damage.

Downloading an OS

Preliminary

Before installing the new operating system on the PLC, you are advised to:

operations

l copy the contents of the CD-ROM containing the OS into a hard disk directory

and work from this directory (downloading time optimized),

l consult the Readme.txt file document on the CD-ROM.

Disconnect the PLC from all networks before downloading.

The Uni-telway driver must be installed on the terminal and must be the only resident

driver.

Dedicated features of the TSX Micro: set the "Write Project" micro-switch (situat-

ed in the battery recess), into the OFF position. When the download is complete, put

the micro-switch back into the ON position.

How to select an Carry out the following steps:

Communication error during downloading

Introduction

Communication errors are caused by certain events (loss of connection, power out-

age…).

These errors can be classified into two types:

l minor,

l fatal.

Minor errors

Example: disconnection of the terminal port.

A dialog box offers whether to continue or to stop the download :

l select the Repeat command after having fixed whatever was causing the down-

load to be interrupted or,

l select the Abort load command : the PLC passes into "loading" mode, so you

will have to restart a new download of the operating system in order to use the

PLC,

l click on OK to return to the main window.

Fatal errors

Example: power outage.

The PLC then becomes unusable. The leds RUN, I/O and ERR are constantly lit and

the terminal/PLC dialog is impossible.

Print management in Windows

Introduction

Print management is a Windows application that manages print works.

When you print a document from a Windows application this transmits to the print

manager all the information on the printing, the fonts and the document file.

Description

Print management:

l takes care of printing the document while you continue to work on other Windows

applications,

l indicates problems if an error occurs,

l prints the documents on a local or network printer.

Note: It is possible to print several documents at a time or one document after the

other. The documents are then placed in a queue which is used to verify printing

information.

How to install a

Carry out the following steps:

printer

Glossary

Animation table

Table created by the user or created contextually from within a language editor or

an operating screen.

In connected mode allows you to view the development of the PLC’s variables and

to force the values when debugging.

ASCII

American Standard Code for Information Interchange.

Is pronounced "aski".This is an American code (but has become an international

standard) which allows by means of 7 bits the definition of all the alphanumeric char-

acters used in English, punctuation marks, certain graphical characters as well as

various commands.

Auto Run

Function which allows you to automatically execute the application program on the

PLC at initialization.

BIT

Contraction of the English words Binary Digit.

This is the binary unit of information which can represent two distinct values (or

states) :0 or 1. A field of 8 bits makes up what we call 1 Byte or 1 octet.

Block functions

Blocks contained in the PL7 product (defined by Schneider).

The user has only to parameterize these blocs in the variables editor heading "Pre-

defined FB".

These blocks are:

431

Glossary

l Timer,

l Monostable,

l Up/down counter,

l Drum,

l Register.

Breakpoint

Used in "debug" mode in the application.

It is unique (only one at a time) and once reached, signals to the processor to stop

the execution of the program.

Used in connected mode, it can be positioned in one of the following program ele-

ments:

l Ladder rung,

l Structured Text or Instruction List statement,

l Structured Text line (line mode).

Comment

A comment of 508 characters can be associated to each address even if the latter

does not have a symbol, from within the variables editor.

Comment for ST

The comment (optional) can be integrated anywhere in a statement.It is separated

language

at both ends by the characters (*and *)and can occupy a maximum of 128 lines.Its

size is limited to 256 characters (new lines are included in the count).

The comments are stored in the PLC and can be accessed at any time by the us-

er.They therefore use up program memory.

Constants

Memory unit (Bit, Word, Dword, etc.) whose contents cannot be modified by the pro-

gram being executed.

CPU

Central Processing Unit

This is the microprocessor.It is made up of the control unit and the arithmetic logic

unit.The purpose of the control unit is to extract from the central memory the instruc-

tion to be executed as well as the data necessary for the execution of this instruction,

to establish the electric connections in the arithmetic logic unit and to start the data

processing in this unit.You can sometimes find ROM or RAM memories included

on the same chip, or even I/O interfaces or buffers.

Central Unit: generic name for Schneider Automation processors.

432

Glossary

DFB

The DFB types (Derived Function Blocks) are function blocks which can be pro-

grammed by the user in ST or LD language.

Using these DFB types in an application:

l simplifies the design and input of the program,

l improves the readability of the program,

l facilitates its debugging,

l decreases the amount of code generated.

PL7 Pro software is needed to create a DFB type.

DFB instance

This regards a copy of a DFB type when the latter is called from within a language

editor.

The instance has a name. Input/output interfaces, public and private variables are

duplicated (one duplication per instance, the code is not duplicated)

A DFB type can have several instances.

Documentation

Contains all the information on the application, the documentation is printed after be-

ing put together and is used for maintenance purposes.

It contains information regarding:

l hardware and software configuration,

l the program,

l the DFB types,

l the variables and the animation tables,

l the cross references.

When putting the documentation together, it is possible to include only certain head-

ings, if the user so wishes.

Driver

Program which informs the operating system of the presence and characteristics of

a peripheral.

Events

Software or hardware initiated modules (module operation).

Events have priority over MAST or FAST tasks, they are executed as soon as they

are detected.

Event EVT0 has the highest priority, the others have the same level of priority.

433

Glossary

FAST task

Task activated periodically (the period controlled in the configuration of the proces-

sor) used to execute a part of an application with superior priority to a MAST (mas-

ter) task.

Flash EPROM

PCMCIA memory cards:

l internal (TSX37) containing program, constants, memory %MW,

l external (TSX37-57) containing program and constants.

FNES

Fichiers Neutres d’Entrées Sorties (Input/Output Neutral Files).The FNES format

describes the PLCs in terms of rack, cards and channels using a tree structure.

It is based on the CNOMO standard (Comité de Normalisation des Outillages de Ma-

chines Outils).

Function

Functions delivered with PL7 and accessed from the Tools/Library menu.

The user has only to parameterize these functions. He can develop others with the

help of a development kit SDKC which is an option of PL7.

Function view

View allowing you to see the program part of the application by means of functional

modules created by the user (see definition Functional module).

Functional

A functional module is a grouping together of program elements (sections, subrou-

module

tines, macro-steps, animation tables, operating screens…) intended to carry out an

automation function.

A functional module can itself be broken up into functional modules of a lower level,

these modules taking on, in relation to the main function, one or several automation

sub-functions.

Grafcet

Grafcet language.

Grafcet language conforms to "Sequential Function Chart" language (SFC) of the

IEC 1131-3 standard.

Grafcet allows the operation of sequential automation to be represented graphically

and in a structured manner.This graphical description of the automated sequential

performance and the different situations which arise is carried out with the help of

simple graphical symbols.

434

Glossary

Instructions for

An instruction can be either simple (Assign, Increment, Call SR…) or control struc-

ST language

ture (IF, WHILE, FOR, REPEAT...). The character ; is obligatory at the end of each

instruction.

Label

A label (optional) allows you to find a statement or a rung in a program module and

is required to allow a jump after a GOTO instruction.The following syntax %Li:with i

between 0 and 999.

The label is positioned at the beginning of the statement or rung and can only be

assigned to a single statement or rung within the same program module.The order

of label address is not important, it is the input order of the statements or rungs which

is taken into account by the system at scanning.

Ladder

Rung language.

A program written in rung language is composed of a series of rungs executed se-

quentially by the PLC.

LIST

Instruction list language.

A program written in instruction list language is composed of a series of instructions

executed sequentially by the PLC.Each instruction is composed of an instruction

code and an operand.

Macro-step

A macro-step is the symbolic representation of a unique set of steps and transitions,

which starts with an input step (IN) and terminates with an output step (OUT).

A macro-step can call another macro-step (nesting).

Mono task

Application made up of a single task, has to be a MAST task (master task).

Multi task

Application made up of several tasks (MAST, FAST, event).

An order of priority for task execution is defined by the PLC’s operating system.

435

Glossary

Operating screen This is a tool integrated into software applications PL7-PRO and PL7-PRODYN from

version 3.0 onwards. It is intended to facilitate the operation of an automated pro-

cess. The end-user controls and monitors the operation of the installation and in

case of a problem, he can act quickly and easily.

Protection

Function preventing the reading of the contents of a program module (read protec-

tion), or the reading and modifying of the contents of a program module (read/write

protection).

Protection is confirmed by a password.

RS 232C

Communication series standard which defines among others the following service

voltage:

l a signal of +12V indicates a digital 0,

l a signal of -12V indicates a digital 1.

However detection to thresholds of +3V and -3V is allowed in case of a weakened

signal.

Between these two bounds, the signal will be considered invalid.

RS 232 links are quite sensitive to interference.The standard recommends not ex-

ceeding 15metres in distance and 9600 bauds (bits/sec) maximum.

RS 485

Communication series standard which works differentially at 10V/+5V.It uses 2

wires for sending and receiving.Its "3-state" output allows it to go into listening mode,

when the transmission has finished.

Run

Function which allows you to execute the application program on the PLC.

436

Glossary

Rung

A rung is entered between two potential bars in a Ladder editor and is composed of

a group of graphical elements joined to each other by horizontal or vertical links.The

maximum dimensions of a rung are 16 lines and 11 columns (for PLCs TSX/PMX/

PCX 57), or 7 lines and 11 columns (for PLCs TSX 37) split into two zones:the test

zone and the editing zone.

Section

Program module belonging to a task (MAST, FAST) which can be written in a lan-

guage chosen by the programmer (Structured Text, Ladder, List, Grafcet).

A task can be made up of several sections, the order of execution of the sections

within the task corresponds to the order in which they were created. This order can

be modified.

Structured text language.

Structured text language allows you to create programs by writing lines of code com-

posed of alpha-numeric characters.This language can only be used for the software

PL7 Junior and PL7 Pro on PLCs TSX/PMX/PCX 57. In the version PL7 Pro, this

language allows the creation of user function blocks DFB.

Statement

Basic unit of List language or Structured Text language.

A statement is made up of lines, which are themselves made up of instructions.

It begins with an exclamation mark, can include a comment and can be marked with

a label.

Step

A Grafcet step designates a state of sequential operation of automation.

Initial step defines the initial automation situation.

Single step defines a stable automation situation.

Actions can be associated.These can be expressed in Ladder, Structured Text or

List language.

Stop

Function which allows you to stop the execution of the application program on the

PLC.

Subroutine

Program module belonging to a task (MAST, FAST) which can be written in a lan-

guage chosen by the programmer (Structured Text, Ladder, List).

A subroutine can only be called by a section or another subroutine (nesting) belong-

ing to the task in which it is registered.

Symbol

A symbol is a string of a maximum of 32 alpha-numeric characters, of which the first

character is alphabetic.

437

Glossary

It allows you to personalize a PLC object in such a way as to facilitate the maintain-

ability of the application, it is used on the PLC if the user wants to.

Task

Group of sections and subroutines, executed cyclically or periodically for the MAST

task or periodically for the FAST task.

A task has a level of priority which is linked to the input and output.

Time Out

Exceeding delay.

Stopping of the application or deconnection following a too-long period of inactivity.

Transition

A transition indicates the possibility of development between several steps.

A transition condition called Receptivity is associated with it.

The transition is valid if :

l the upstream steps (directly linked to this step) are active,

l the associated receptivity is true.

The releasing of a transition provokes the change of status for the steps which are

linked to it.

The receptivities are expressed in Ladder, Structured Text or List language.

Variable

Memory unit of a type (Bit, Word, Dword, etc.) whose contents cannot be modified

by the program being executed.
