1 General
The PAB is a unit that acts as an interface between an external controller and ESAB
welding equipment. This document will describe the different ways to do this both
with set-up of the system and during welding.
In the tables you will sometimes see greyed-out areas, information about these can
be found in Advanced use.
In this document the terms cyclical data, asynchronous data and web interface will be
used and here the terms means the following:
• Cyclical data, this is the data that can be updated in the external controller’s
communication loop (hence cyclical). Typically this data is process oriented;
data that affects the weld directly (e.g. voltage, current etcetera)
• Asynchronous data, this is data that usually is changed when the welding is off
and can be for process settings or set-up of the system
• Web interface, this is typically set-up data, both for configuration of the system
but also for creation and handling of weld data sets
There exists a certain overlap between the different communication protocols. This is
necessary but could cause some confusion. Therefore it is important to understand
when to use the different protocols and to what end.
In general we can divide this into two scenarios: what you do during welding and
what you do to set up the system.
During welding it is possible to change individual parameters, like voltage and
current, to trim the welding process. This is typically done by the operator in ‘real
time’ and will give an instant feedback.
Still, you might want to change between two (or more) different weld cases, e.g.
switch from DC welding to AC welding on-the-fly. In that case you may want to
change more than a single parameter. This can be done by two different methods;
either use the double cyclical input area or use weld data sets. When either of these
two methods are used all changed parameters will take effect at the same time on a
switch command. Please note that when switching between weld data sets the input
area (from the PAB’s point of view) will not contain updated values. The reason for
this is that the input area is a read-only area for the PAB due to the master-slave
concept of the fieldbus and is the responsibility of the controlling unit, e.g. PLC. The
output area with the set values will, however, be updated.
NOTE: In previous versions of the Profinet/-bus profiles PAB tandem handling has
been an option. With this release the tandem handling has been removed and is left
for the integrator to implement in the controlling unit (e.g. PLC).This will simplify the
set-up of the system and give the integrator a better control of the sequence. The
same goes for start and stop phases.

the bus termination is handled by a switch on the Anybus card. Some devices, like
optical transceivers (RS-485 to fiber optics) might require external power supply from
these pins. PTS is used in some equipment to determine the direction of
transmission. In this application only A-line, B-line and Shield are used.
5.1.9 Configuration
Baudrate
The baudrate on a Profibus-DP network is set during configuration of the master and
only one baudrate is possible in a Profibus-DP installation. The PAB has an auto
baudrate detection function and the user does not have to configure the baudrate on
the module.
Baudrates (in kbps) supported by the PAB are:
9.6
19.2
93.75
187.5
500
1500
3000
6000
12000
Termination
The end node in a Profibus-DP network has to be terminated to avoid reflections on
the bus line. The circuit board inside the PAB is equipped with a termination switch to
accomplish this in an easy way.
The PAB shall not be terminated using this switch, if termination is needed this has to
be handled by an external termination connector.
7
14
PLEASE NOTE: Make sure that the switch is in the OFF position.
Node Address
The PAB is equipped with two rotary switches on the module inside, this enables
address settings from 1 – 99 in decimal format. Please note that the address is set by
the application program inside the PAB and that the switches therefore will not have
any impact on the address.
PLEASE NOTE: The node address is not read from the switches.
GSD file
Each device on a Profibus-DPV1 network is associated with a GSD file, containing all
necessary information about the device. This file is used by the network configuration
program during configuration of the network.
The latest version of this file can be received by contacting ESAB.
5.1.10 Indications
The circuit board is equipped with four LED’s mounted at the front and one LED on
the board, used for debugging purposes. The function of the LED’s are described in

5.2 Profinet
5.2.1 Introduction to PROFINET
Profibus has an international user organisation called Profibus & Profinet
International, PI, and local national organisations, PNO. Technical questions
regarding the fieldbus should be addressed to your local Profibus User Group in the
instance. Address list is available on the Profinet Internet Site;
http://www.profinet.com. For general help on Profinet, contact Profibus & Profinet
international on e-mail; info@profibus.com. Profinet is normally used in industrial
automation, to transfer fast data for motor controllers, MMI, I/O units and other
industrial equipment.
5.2.2 Network overview
PROFINET IO is very similar to Profibus but on Ethernet. While Profibus uses cyclic
communications to exchange data with Programmable Controllers at a maximum
speed of 12 Mbaud over a twisted copper pair (or fibre optics), PROFINET IO uses
cyclic data transfer to exchange data with Programmable Controllers over Ethernet.
As with Profibus, a Programmable Controller and a device must both have a prior
understanding of the data structure and meaning. In both systems data is organized
as slots containing modules with the total number of I/O points for a system the sum
of the I/O points for the individual modules.
5.2.3 Technical features for PROFINET
TBD
5.2.4 Mechanical Overview
The PAB is a slave node that can be read and written to, from a PROFINET master.
The PAB will not initiate communication to other nodes, it will only respond to
incoming commands.
5.2.5 Protocol and Supported Functions
• ROFINET IO- Up to 64 slots / 1 subslot
• Up to 1024 bytes cyclical I/O (512 input & 512 output)
• 2ms cycle time
5.2.6 Physical Interface
Mainly full-duplex with 100 MBit/s electrical (100BASE-TX) or optical (100BASE-FX)
according to IEEE 802.3 are recommended as device connections. Autocrossover is
mandatory for all connections so that the use of crossover cables can be avoided.
From IEEE 802.1Q the VLAN with priority tagging is used. All real-time data are thus
given the highest possible priority 6 and are therefore forwarded by a switch with a
minimum delay.

The Profinet protocol can be recorded and displayed with any Ethernet analysis tool.
Wireshark also decodes the Profinet telegrams in the current version.
The Link Layer Discovery Protocol (LLDP) has been extended with additional
parameters, so that in addition to the detection of neighbours, the propagation time of
the signals on the connection lines can be communicated.
5.2.7 Configuration and Indications
• LED indicators: ON-line, OFF-line, Fieldbus related diagnostics
• I/O data transmission: The module supports cyclic I/O data transmission.
• Acyclic data transmission: The module supports acyclic data transmission.

6 USB Memory
The PAB is delivered with a USB memory stick attached.
Please note that this USB memory stick has to be attached at start up and also
when using the web interface. Recommended is to keep it mounted at all times and
to read/write files through the FTP client. If necessary the USB memory can be
removed to allow for backing up of data or updating the web interface, just make sure
it is present during start up and regular usage.
There is also a possibility to add an external USB memory stick in addition to the one
mentioned above and this external memory is mirrored by the software to an FTP
area.
Exported data is put in a folder named ftpsrv on the external USB memory and if you
want to import files they also have to reside in that folder.
If you connect to the FTP area you will see the above directory. Connection to the
FTP area can be via a web browser or an FTP program.
There are several files and folders on the internal USB memory and they will be
described below.
6.1 Configuration File
This file is used for set-up of items necessary for the PAB prior to communication
with the controlling unit (e.g. PLC).
The file contains:
7
20
NodeAddress is the PAB’s Profibus address (for Profinet users, the value does not
matter) and has to be set to different values in each PAB if more than one PAB is
present in the network.
EthernetAdress is the address where you can reach the web page and FTP server.
The connection for this is on the PAB motherboard (for Profinet users the Profinet
connector is on the small daughterboard).
To start the webserver you just need to connect with your computer to the PAB and
type in the Ethernet address specified in the config.xml file and you will get to the
home page. Please note that you have to set up your computer with a fixed IP
address (different from the one in the config.xml file) in the same range as the PAB;
in this case 192.168.0.X, where X cannot be “5”.
The same goes for the FTP server, just open a browser window and type in
ftp://192... (the above specified address) and you will get a file view of the FTP area.
You can also use a FTP client like Filezilla or similar to connect.
UseMotorCard if you have an ESAB FAA connected for motor control then set this
to “1”, as in the example. If you have your own motor control then set this to “0”. See
Motor Configuration for more information.
MeasureFrequency it is possible to set the output frequency of the measurement
values from the welding equipment to a value between 1 and 10 Hz. Default is 1 Hz.
6.2 Web Interface
The files used by the web interface are located in the “websrv” folder. Please see
Web Interface for more information on how to use this functionality.
6.3 Fieldbus information
This fieldbus profile as well as the GSD files for PLC adaptation are also found in the
directory “Documents” of the USB memory stick.
7
21
6.4 Import and Export Directory (external USB)
The directory “ftpsrv” is the source and destination for files imported and exported to
and from the PAB. Please see Import Settings/Data and Export Settings/Data for
more information. If you want to import files and the directory is missing then please
just create a directory with the name “ftpsrv” in the root area of the external USB and
put the files to be imported there.

7 Basic Setup
There are some settings which have to be set up in every application. This chapter
will try to list these settings and explain why they have to be defined.
7.1 Motor Configuration
For the specific application the integrator has to decide what motor drive to use.
Basically there are two options: ESAB FAA or external controller.
ESAB FAA is a two motor controller and is standard for our automation range.
Different motors can be chosen to cater for different needs (travel, wire). The FAA
can be used for wire control only if desired, see below.
External controller is an integrator supplied controller that is driven by the PLC. The
set values are still supplied by the PAB and should be forwarded to the external
controller. If this is not done for the wire control then the CA and CC modes will not
work, and if not used for travel control then the issues would be scratch start and
measure data for heat input. There could be other effects as well. The
recommendation, therefore, is to use the requested speed values output by the PAB.
For FAA usage the settings are:
• The “UseMotorCard” in the config.xml file has to be set to “1”
• Chose FAA or external drive for the travel movement (Travel Motor Drive):
o FAA: set this to “on”
o External: set this to “off”
For external controller the settings are:
• The “UseMotorCard” in the config.xml file has to be set to “0”
• External drive has to be chosen for the travel movement (Travel Motor Drive):
o set this to “off”
All motor settings can be found in the chapter Motor Handling. You will also find the
in- and output area information in said chapter, you will need this information
regardless of chosen motor drive.
Please also see Application Examples for additional information.
7
23
7.2 Unit of Length
Note: for all parameters based on length (like speed) you need to make sure you
have the correct setting for what you want to use, cm or inch. If this setting is
incorrect with regards to the values you set then the system will not work as
intended. Make sure to check that you have this set up correctly.

8 Functional I/O Data Map
The data in this section is generally process data. The communication is controlled
by the external bus master and is cyclical. The master writes to and reads from
memory areas in the slave. The speed and refresh rate on the bus is set by the
master.
8.1 In I/O from Controller to Welding Equipment
This data area is 64 byte long.
The input area is divided into two 28 byte long sub areas and one common area. This
division is used with one area being the active area and the other one being the
passive area. Which area that is active and passive is selected via a switch in the
command area. Please note that the common area is not included in the switch and
will remain active for both input areas.
The status information in the output area will show which area is active and which is
passive. Any data updated in the passive area will just be stored and no action will be
taken at that moment. When the areas are switched all data in the previously passive
area will be engaged at the same moment thus minimizing the effect of the transition.
Please see Input Area Switching for more information.

Weld On starts the weld when set to one (‘1’). If the weld doesn’t start, please check
error status.
To stop the weld set this bit to zero (‘0’).
8.1.1.1.2 Quick Stop
This bit, when set to one (‘1’), performs a Quick Stop if the Equipment is in a welding
procedure. Quick Stop means that the Welding Equipment will do a normal stop
procedure without a craterfill.
This function is used when a fast stop is required but it will handle burnback the
normal way to avoid that the wire get stuck in the weld pool. This bit will also block a

Bit 8-15 is Regulation Type:
Value 0: CA
Value 1: CW
Value 2: CC
8.1.2.1.1 CA
CA stands for Constant Amperage. In the CA mode the power source regulates both
the voltage and the current. The current is regulated with help of the wire drive. In
this mode the wire speed will vary to keep the current level.
8.1.2.1.2 CW
CW stands for Constant Wire. In the CW mode the power source regulates the
voltage. The wire speed is held constant and thus the current will be allowed to vary.
8.1.2.1.3 CC
CC stands for Constant Current. In the CC mode the power source regulates both
the voltage and the current. The voltage is regulated with help of the wire drive. In
this mode the wire speed will vary to keep the voltage level.
Aristo 1000 only.
Voltage
The voltage parameter is a 16 bit unsigned number with the resolution of 0.1V. To set
a voltage of 25V this parameter has to be set to 250.
Current
The current parameter is a 16 bit unsigned number with the resolution of 1A. To set a
current of 500A this parameter has to be set to 500.
7
30
AC Frequency
AC Frequency is a 16 bit unsigned number with a resolution of 1Hz. To set an AC
Frequency of 50 Hz, this parameter has to be set to 50.
When running several AC power sources in tandem the frequency set for the leading
AC power source will be set also for the trailing AC power sources.
This setting is for Aristo 1000 only.
AC Balance
AC balance is a 16 bit unsigned number with a resolution of 1%. To set an AC
balance of 70%, this parameter has to be set to 70.
The percentage value is the positive period’s part of the total period.
This setting is for Aristo 1000 only.
AC Offset
AC offset is a 16 bit unsigned number with a resolution of 0.1V. The AC Offset can
be either positive or negative. When negative, two’s complement is used.
To set an offset voltage of -2.5V this argument has to be set to 65511 (i.e. 65536 –
25).
This setting is for Aristo 1000 only.
AC Phase Shift
When welding with more than one AC power source in tandem the possibility to
introduce phase shift between the leading AC power source and the trailing power
source(s) may prove beneficial. This setting will allow the user to set the phase shift
between the leading AC power source and this power source.
AC Phase Shift is a 16 bit unsigned number with a resolution of 1°. To set an AC
Phase Shift of 90° this argument has to be set to 90.
This setting is for Aristo 1000 only.
7
31
Start Adjust
Start Adjust is a 16 bit unsigned number with a resolution of 1%. This value can be
updated at all times. Start adjust will adjust the start table result with the percentage
set. This can help getting better start result when there are variations in the
conditions that the power source does not have any information about.
To set a Start Adjust of 150% this argument has to be set to 150. Note that the
default value for this setting is 100% and that you can set this between 50 and 200%
Regulation Dynamics
Regulation Dynamics is a 16 bit unsigned number with the resolution of 1. To set the
regulation dynamics to 50 this parameter has to be set to 50.
Ranges for the settable spectrum when it comes to Regulation Dynamics differ
between Aristo 1000 and LAF/TAF systems. Please see reference [1] for more
information on this setting.
Regulation Inductance
Regulation Inductance is a 16 bit unsigned number with the resolution of 1. To set
the regulation inductance to 40 this parameter has to be set to 40.
This parameter is only valid for the Aristo 1000. Please see reference [1] for more
information on this setting.

9 Asynchronous Communication
The asynchronous communication is done via slots and indices. Each function is
assigned a number that is used as the index.
The reply will be formatted per function.
9.1 Asynchronous Communication Sequences
9.1.1 Read Sequence
Read request sent with function number as index. Return value contains data and
error information. For most of the read functions the return values will be in the
format of three (3) unsigned short variables, the value and a minimum and maximum
range for the said value. Return value could look like this:
B0 B1 B2 B3 B4 B5
|____| |____| |____|
Value Min Max
Where B0 B1 forms the first variable:
B0.7
B0.6
B0.5
B0.4
B0.3
B0.2
B0.1
B0.0
B1.7

B1.3
B1.2
B1.1
B1.0
0 1 0 0 1 1 0 0 0 0 0 0 1 1 1
1
In this example the variable has the value 0x4C0F.
The following variables accordingly.
If an argument has to be passed with the read function (to select an element in an
array, for example) then this argument will have to be passed via a write sequence in
advance.
9.1.2 Write Sequence
The write sequence works in a similar way as the read sequence but now the
argument is passed on to the PAB. So, slot and index, where index is the function
number, is sent along with the value to be written. The only return value from a write
sequence is the outcome of the function (i.e. Error code).
9.1.3 Error Codes
The read or write function contains a number of error checks and will return error
codes if an error is detected. In the table Error Code is combined from ErrorCode1
(MSB) and ErrorCode2 (LSB).
The error codes for the different fieldbus implementations are shown below.

10.1 Weld data handling
10.1.1 Input Area Switching
To be able to switch seamlessly between two different weld cases we provide two
weld parameter areas that the user can switch between. On user command all data
is transferred to the power source and then activated so that there will not be any
delay between the different parameters and the activation of them.
The two input areas are numbered one (1) and two (2). One of the sets is active and
the other passive, in the meaning that the set transferred (switched to) is the active
set and the other set is the passive one.
The parameters in the active set can be changed on the fly. Any change to the
passive area is stored but not acted on until the switch making the passive area
active is performed.
It is recommended that during start-up of the system the controlling unit (e.g. PLC)
transfers first all the data pertaining to the first weld case to the passive area. Then
switches this to the active role and then fill up the now passive area with data for the
second weld case.
Please see In I/O from Controller to Welding Equipment for information on mapping
of the areas.

10.1.1.1.1.1 Input Area Switch
There are two different weld data areas, one active and one passive. The user can at
any time switch the areas so that the active area becomes passive and vice versa.
This way a weld data switch is done; the changes done this way will all be performed
at the same time (i.e. no delays between the parameter updates as would have been
the case if a sequential change had been made).
The switch is performed when this bit changes polarity.

10.1.2 Weld Data Set
The other way of handling weld data is to pre-define weld data sets and store them in
the PAB. When you have your desired weld data sets you can switch between them
whenever you want, even on the fly during welding.
A complete set of weld data includes all weld data settings that can be made in the
Weld Data Unit (see reference [1]).
Among a large number of setting values this includes:
• Wire Type
• Wire Dimension
• Weld Method
• Start Data
• Stop Data
It is possible to store up to 255 weld data sets in the PAB memory.
Handling of weld data sets can be found at Asynchronous Weld Data Set Functions
and also in the Web Interface section.

10.2 Motor Handling
To be able to take advantage of the power source welding capabilities to the fullest
the power source has to command the wire drive. Either by using our FAA unit or that
the controlling unit directs an external motor drive to follow the requested wire speed
output by the power source.
The travel motor drive is of less importance to the weld process but can still be
controlled in the same way as the wire drive.
