Trajexia system

PROGRAMMING MANUAL 6

Revision 1.0

2 Trajexia system

2.1 Introduction

fig. 1

Trajexia is OMRON's motion platform that offers you the performance and
the ease of use of a dedicated motion system.

Trajexia is a stand-alone modular system that allows maximum flexibility and
scalability. At the heart of Trajexia lies the TJ2 multi-tasking machine
controller. Powered by a 64-bit processor, it can do motion tasks such as e­cam, e-gearbox, registration control and interpolation, all using simple
motion commands.

The TJ2-MC64 offers control of up to 64 axes over a MECHATROLINK-II
motion bus or traditional analogue or pulse control with independent
position, speed or torque control for every axis. And its powerful motion
instruction set makes programming intuitive and easy.

You can select from a wide choice of best-in-class rotary, linear and direct­drive Servo systems as well as Inverters. The system is scalable up to 64
axes and 8 Inverters & I/O modules.

The TJ2-MC64 also contains an IEC 61131-3 compliant soft PLC, capable of
controlling I/O and performing motion.

2.1.1 Trajexia hardware

The Trajexia hardware is described in the Trajexia Hardware Reference
manual. It is recommend to read the Hardware Reference manual first.
The Trajexia system gives these advantages:

Direct connectivity via Ethernet

Trajexia's built-in Ethernet interface provides direct and fast connectivity to
PCs, PLCs, HMIs and other devices while providing full access to the CPU
and to the Drives over a MECHATROLINK-II motion bus. It allows explicit

possible.

Trajexia system

PROGRAMMING MANUAL 8

Revision 1.0

Keep your know-how safe

By preventing access to the programs in the controller Trajexia guarantees
complete protection and confidentiality for your valuable know-how.

Serial Port and Local I/Os

A serial port provides direct connectivity with any OMRON PLC, HMIs or any
other field device. 16 Inputs and 8 outputs are freely configurable embedded
I/Os in the controller to enable you to tailor Trajexia to your machine design.

MECHATROLINK-II Master

The MECHATROLINK-II master performs control of up to 16 Servo Drives,
Inverters or I/Os while allowing complete transparency across the whole
system.MECHATROLINK-II offers the communication speed and time
accuracy essential to guarantee perfect motion control of Servo Drives. The
motion cycle time is selectable between 0.5 ms, 1 ms or 2 ms.

TJ1-FL02 (Flexible Axis Unit)

The TJ1-FL02 allows full control of two actuators via an analogue output or
pulse train. The module supports the main absolute encoder protocols
allowing the connection of an external encoder to the system.

Drives and Inverters

A wide choice of rotary, linear and direct-drive Servo systems as well as
Inverters are available to fit your needs in compactness, performance and
reliability. The Inverters connected to the MECHATROLINK-II are driven at
the same update cycle time as the Servo Drives.

Remote I/Os

The I/Os on the MECHATROLINK-II motion bus provide for system
expansion while keeping the devices under one motion bus.

PROFIBUS-DP

The PROFIBUS-DP slave allows connectivity to the PROFIBUS network in
your machine.

DeviceNet

The DeviceNet slave allows connectivity to the DeviceNet network in your
machine.

CANopen

The CANopen master allows connectivity to the CANopen network in your
machine.

Modbus

Both ModbusRTU via serial and ModbusTCP via Ethernet are supported to
be able to connect to masters supporting the same interface.

2.1.2 This manual

This Programming Manual gives the dedicated information for:

• The description and use of the BASIC commands

• The communication protocols necessary for the Trajexia system

• The use and description of the parts of the Trajexia Studio interface

• Program examples and good programming practices

• Troubleshooting and fault finding.

2.2 Multitasking BASIC programming

The TJ2-MC64 units (Machine Controller Unit) feature a multitasking version
of the BASIC programming language. The motion control language is largely
based upon a tokenised BASIC and the programs are compiled into the
tokenised form prior to their execution.
Multitasking is simple to set up and use and allows very complex machines
to be programmed. Multitasking gives the TJ2-MC64 a significant advantage
over equivalent single task systems. It allows modular applications where
the logically connected processes can be grouped together in the same task
program, thus simplifying the code architecture and design.
The TJ2-MC64 can hold up to 32 programs if memory size permits. Up to 22
programs can be run simultaneously. The execution of the programs is user
controlled using BASIC.
The BASIC commands, functions and parameters presented here can be
found in chapter 3.

Trajexia system

PROGRAMMING MANUAL 9

Revision 1.0

2.3 BASIC programming

The BASIC language consists among others of commands, functions and
parameters. These BASIC statements are the building blocks provided to
control the TJ2-MC64 operation.
Commands are words recognized by the processor that perform a certain
action but do not return a value. For example, PRINT is a recognized word
that will cause the value of the following functions or variables to be printed
on a certain output device.
Functions are words recognized by the processor that perform a certain
action and return a value related to that action. For example, ABS will take
the value of its parameter and return the absolute value of it to be used by
some other function or command. For example ABS(-1) will return the value
1, which can be used by the PRINT command, for example, to generate a
string to be output to a certain device.
Parameters are words recognized by the processor that contain a certain
value. This value can be read and, if not read only, written. Parameters are
used to determine and monitor the behavior of the system. For example,

ACCEL determines the acceleration rate of a movement for a certain axis.

2.3.1 Axis, system and task statements

The commands, functions and parameters apply either to (one of) the axes,
the tasks running or the general system.

Axis statements

The motion control commands and the axis parameters apply to one or more
axes. Axis parameters determine and monitor how an axis reacts on
commands given and how it reacts to the outside world. Every axis has a set
of parameters, so that all axes can work independently of each other. The
motion control commands are able to control one or more of the axes
simultaneously, while every axis has its own behavior. The axis parameters
are reset to their default values for each startup.
The commands and parameters work on some base axis or group of axes,
specified by the BASE command. The BASE command is used to change
this base axis group and every task has its own group which can be changed
at any time. The default base axis is 0.

Individual axis dependent commands or parameters can also be
programmed to work on a temporary base axis by including the AXIS
function as a modifier in the axis dependent command. A temporary base
axis is effective only for the command or parameter after which AXIS
appears.

Task statements

The task parameters apply to a single task. The task parameters monitor the
task for example for error handling. The PROC modifier allows the user to
access a parameter of a certain task. Without PROC the current task is
assumed. The BASE command (see above) is task specific and can be
used with the PROC modifier.

System statements

These statements govern the overall system features, which are basically all
statements which do not belong to the first two groups.

2.3.2 Memory areas

Three main memory areas can be identified in the Trajexia Motion Controller
Unit:

• I/O memory.

• VR memory.

• TABLE memory.

I/O memory

I/O memory is used for holding the status of input and output devices
connected to the Trajexia system. It is divided into two sub-areas: one for
digital I/O memory, and one for analog I/O memory. The digital I/O memory
holds input and output statuses of digital I/O devices. Its capacity is 256 bits
(input points) for input and 256 bits (output points) for outputs. The inputs in
this memory can be accessed using the IN command. The outputs can be
accessed using the OUT command.
The analog I/O memory holds input and output values of analog I/O devices.
Its capacity is 36 input channels and 36 output channels. The analog input
channels can be accessed using the AIN command. The analog output
channels can be accessed using the AOUT command.

Trajexia system

PROGRAMMING MANUAL 10

Revision 1.0

VR memory

VR memory is commonly used if some data or value needs to be global,
which means that it is accessible from all programs in the project at the
same time. The size of this memory is 64,000 slots with indexes 0 to 63,999.
A memory slot is addressed using the VR(x) macro where x is index of the
VR memory slot. The VR memory is accessible for reading and writing.
Writing is done by making mathematical assignment using the = command
in the program. The content of this memory is held in the battery powered
RAM memory and is preserved during power off. The VR memory is also
preserved when changing the battery, if this is done quickly.

TABLE memory

TABLE is commonly used if some data or value needs to be global, which
means that it is accessible from all programs in the project at the same time.
Whereas the VR memory is used for similar purposes to define several
global data and values, TABLE memory is used for much bigger amounts of
global data, which also need to be arranged in a certain order. For this
reason, TABLE memory is commonly used for storing TABLE data, motion
profiles, logging data, etc. Some BASIC commands that provide this type
and size of data, for example SCOPE, CAM, CAMBOX etc., require use of
TABLE memory to write their results. The size of this memory is 500,000
slots with indexes 0 to 499,999. The TABLE is accessible for reading and
writing too, but the way it is accessed differs for those two operations. Before
being read, a particular TABLE memory slot needs to be defined and written
first, using the command TABLE(x, value1, value2,…) where x is the index
of the start TABLE memory slot to define, and value1, value2, ... are the
values written into the TABLE memory at indexes x, x+1, ... Once defined
and written, the TABLE memory slot can be read using the TAB LE(x)
command, where x is the index of the TABLE memory slot. An attempt to
read an undefined TABLE memory slot results in an error reported by the
TJ2-MC64. The first 65,536 TABLE memory entries are held in the battery
powered RAM memory and is preserved during power off. This part of the
TABLE memory is also preserved when changing the battery, if this is done
quickly.

2.3.3 Data structures and variables

BASIC programs can store numerical data in various types of variables.
Some variables have predefined functions, such as the axis parameters and
system parameters; other variables are available for the programmer to
define as required in programming. The TABLE, global and local variables of
the TJ2-MC64 are explained in this section. Furthermore also the use of
labels will be specified.

TABLE variables

The TABLE is an array structure that contains a series of numbers. These
numbers are used for instance to specify positions in the profile for a CAM or
CAMBOX command. They can also be used to store data for later use, for
example to store the parameters used to define a workpiece to be
processed.
The TABLE is common to all tasks on the TJ2-MC64. This means that the
values written to the TABLE from one task can be read from other tasks.
TABLE values can be written and read using the TABLE command. The
maximum length of the array is 500,000 elements, from TABLE(0) to
TABLE(499999). The TABLE array is initialized up to the highest defined
element.

Global variables

The global variables, defined in VR memory, are common to all tasks on the
TJ2-MC64. This means that if a program running on task 2 sets VR(25) to a
certain value, then any other program running on a different task can read
that same value from VR(25). This is very useful for synchronizing two or
more tasks, but care must be taken to avoid more than one program writing
to the same variable at the same time. The controller has 64,000 global
variables, VR(0) to VR(63999). The variables are read and written using the
VR command.

Trajexia system

PROGRAMMING MANUAL 11

Revision 1.0

Local variables

Named variables or local variables can be declared in programs and are
local to the task. This means that two or more programs running on different
tasks can use the same variable name, but their values can be different.
Local variables cannot be read from any task except for the one in which
they are declared. Local variables are always cleared when a program is
started. The local variables can be cleared by using either the CLEAR or the
RESET command.
A maximum of 1024 local variables can be declared. Only the first 32
characters of the name are significant. Undefined local variables will return
zero. Local variables cannot be declared on the command line.

Labels

The BASIC programs are executed in descending order through the lines.
Labels can be used to alter this execution flow using the BASIC commands
GOTO and GOSUB. To define a label it must appear as the first statement
on a line and it must be ended by a colon (:). Labels can be character strings
of any length, but only the first 32 characters are significant.

Using variables and labels

Each task has its own local labels and local variables. For example, consider
the two programs shown below:

/i

These two programs when run simultaneously in different tasks and have
their own version of variable a and label start.
If you need to hold data in common between two or more programs, VR
variables should be used. Or alternatively if the large amount of data is to be
held, the TABLE memory can be used.
To make a program more readable when using a global VR variable, two
approaches can be taken. The first is using a named local variable as a
constant in the VR variable. The local constant variable, however, must be
declared in each program using the global VR variable. Using this approach,
the example below shows how to use VR(3) to hold a length parameter
common for several programs:

/i

The other approach is even more readable and uses the GLOBAL
command to declare the name as a reference to one of the global VR
variables. The name can then be used from within the program containing
the GLOBAL definition and all other programs. Take care that the program
containing the GLOBAL definition must be run before the name is used in
other programs. The best practice is to define global names in the start-up
program. Using this approach, the example above becomes:

Note

The TABLE and VR data can be accessed from the different run­ning tasks. When using either VR or TABLE variables, make sure
to use only one task to write to one particular variable. This to
avoid problems of two program tasks writing unexpectedly to one
variable.

2.3.4 Mathematical specifications

Number format

The TJ2-MC64 has two main formats for numeric values: double precision
floating point and double precision integer.
The double precision floating point format is internally a 64 bit value. It has
an 11 bit exponent field, a sign bit and a 52 bit fraction field. Floating point
numbers have a valid range of ±2.2×10

−308

to ±1.8×10

308

.
Integers are essentially floating point numbers with a zero exponent. This
implies that the integers are 53 bits wide. The integer range is therefore
given from -9,007,199,254,740,992 to 9,007,199,254,740,991. Numeric
values outside this range will be floating point.

Hexadecimal format

The TJ2-MC64 supports assigning and printing hexadecimal values. A
hexadecimal number is input by prefixing the number with the $ character.
Valid range is from 0x0 to 0xFFFFFFFFFFFFF. Example:

>> VR(0)=$FF
>> PRINT VR(0)

255.0000

A value can be printed in hexadecimal by using the HEX function. Negative
values result in the 2’s complement hexadecimal value (53-bit). Valid range
is from −xxx to xxx. Example:

>> TABLE(0,-10,65536)
>> PRINT HEX(TABLE(0)),HEX(TABLE(1))
1FFFFFFFFFFFF6 10000

Positioning

For positioning, the TJ2-MC64 will round up if the fractional encoder edge
distance calculated exceeds 0.9. Otherwise the fractional value will be
rounded down. The internal measured position and demanded position of
the axes, represented by the MPOS and DPOS axis parameters, have xxx­bit counters.

Floating point comparison

The comparison function considers a small difference between values as
equal to avoid unexpected comparison results. Therefore any two values for
which the difference is less than <EXOO>1.19×10

−6

are considered equal.

Precedence

The precedence of the operators is given below:

1. Unary minus, NOT

2. ^

3. / *

4. MOD

5. + -

6. = <> > >= <= <

7. AND OR XOR

8. Left to right

The best way to ensure the precedence of various operators is through the
use of parentheses.

WARNING

All mathematical calculations are done in floating point format. This
implies that for calculations of/with larger values the results may
have limited accuracy. The user should be aware of this when
developing the motion control application.

Trajexia system

PROGRAMMING MANUAL 14

Revision 1.0

2.4 Motion execution

Every task on the TJ2-MC64 has a set of buffers that holds the information
from the motion commands given.

2.4.1 Motion generator

The motion generator has a set of up to 64 motion buffers for each axis.
One buffer called MTYPE, holds the Actual Move, which is the move
currently executing on the axis. The next buffer called NTYPE, holds the
Next Move, which is executed after the Actual Move has finished.
See chapter 2.8 “Motion Buffers” in the Trajexia Hardware Reference
manual for detailed explanation.

The BASIC programs are separate from the motion generator program,
which controls moves for the axes. The motion generator has separate
functions for each axis, so each axis is capable of being programmed with its
own axis parameters (for example speed, acceleration) and moving
independently and simultaneously or they can be linked together using
special commands.
When a move command is being processed, the motion generator waits until
the move is finished and the buffer for the required axis has become empty,
and then loads these buffers with the next move information.

Note

If the task buffers are full, the program execution is paused until
buffers are available again. This also applies to the command line
task and no commands can be given for that period. Trajexia Stu­dio will disconnect in such a case. The PMOVE task parameter will
be set to TRUE when the task buffers are full and will be reset to
FALSE when the task buffers are available again.

Trajexia system

PROGRAMMING MANUAL 15

Revision 1.0

2.4.2 Sequencing

On each servo cycle interrupt (see section 2.6.2), the motion generator
examines the NTYPE buffers to see if any of them are available. If there are
any available then it checks the task buffers to see if there is a move waiting
to be loaded. If a move can be loaded, then the data for all the specified
axes is loaded from the task buffers into the NTYPE buffers and the
corresponding task buffers are marked as idle. This process is called
sequencing.

2.4.3 Move loading

Once sequencing has been completed, the MTYPE buffers are checked to
see if any moves can be loaded. If the required MTYPE buffers are
available, then the move is loaded from the NTYPE buffers to the MTYPE
buffers and the NTYPE buffers are marked as idle. This process is called
move loading. If there is a valid move in the MTYPE buffers, then it is
processed. When the move has been completed, the MTYPE buffers are
marked as idle.

2.5 Command line interface

The command line interface provides a direct interface for the user to
execute commands and access parameters on the system.
Use the Terminal Window in Trajexia Studio when the TJ2-MC64 is
connected.
The TJ2-MC64 puts the last 10 commands given on the command line in a
buffer. Pressing the Up and Down Cursor Key will cycle through the buffer to
execute the command again.

2.6 BASIC programs

The TJ2-MC64 can store up to 32 programs in memory, provided the
capacity of memory is not exceeded. The TJ2-MC64 supports simple file­handling instructions for managing these program files rather like the DOS
filing system on a computer.

The Trajexia Studio software package is used to store and load programs to
and from a computer for archiving, printing and editing. It also has several
controller monitor and debugging facilities.

2.6.1 Managing programs

The Trajexia Studio software package is used to store and load programs to
and from a computer for archiving, printing and editing. It also has several
controller monitor and debugging facilities. For more information please refer
to the Trajexia Studio user manual.

Storing programs

Programs in the TJ2-MC64 are stored automatically in Flash-ROM memory
and therefore do not rely on the battery.

2.6.2 Program execution

The timing of the execution for the different tasks and the refreshing of the I/
O of the TJ2-MC64 revolves around the servo cycle period of the system.
The servo cycle period is determined by the SERVO_PERIOD system
parameter. The TJ2-MC64 will either have a servo cycle period of 0.25, 0.5,

1.0 or 2.0 ms.

I/O refresh

The I/O status of the TJ2-MC64 is refreshed at the beginning of every cycle
time.

• The captured status of the digital inputs is transferred to the IN system
input variable. Note that this is the status captured in the previous servo
cycle.

• The analogue outputs for the speed references are updated.

• The digital outputs are updated conform the status of the OP system
output variable.

• The status of the digital inputs is captured.

Trajexia system

PROGRAMMING MANUAL 16

Revision 1.0

Note that no automatic processing of the I/O signals is taking place, except
for registration. This implies that all actions must be programmed in the
BASIC programs.

Relevant commands

Trajexia Studio provides several ways of executing, pausing and stopping
the programs using buttons on the control panel and the editing windows.
The following commands can be given on the command line to control the
execution.

/i

The user can explicitly allocate the task priority on which the BASIC program
is expected to run. When a user program is run without explicit task
allocation, it is assigned the highest available task priority.

Setting programs to run at start-up

Programs can be set to run automatically at different priorities when power is
turned on. If required, the computer can be left connected as an operator
interface or may be removed and the programs run stand-alone.
Programs are set in Trajexia Studio to run automatically at start-up by
setting the startup priority with the Priority property in the Properties window.
If you click the ellipsis button in the edit field of this property, the StartUp
Priority window shows. To set the program to run at power up, select the
Run at Power Up check box and select a priority in the list. Possible priority
values are Default or 0 (lowest priority) to 21 (highest priority).The current
status in the controller can be seen using the DIR command.
For more information on program control, multitasking and cycle times, refer
to sections 2.2 and 2.3 of the Trajexia Hardware Reference Manual.

Command Function

RUN Run the current selected program or a specified program, optionally on a

specified task number.

STOP Stop the current selected program or a specified program.

HALT Stop all programs on the system.

PROCESS Displays all running tasks.
