Profibus-DP Configuration
Module Configuration Switches
From Profibus-DP point of view the Profibus-DP Slave (PDPS) node
is configured based on a data f ile (*.GSD) which conta ins information
of the size and data-structure of the PDPS.
The Master controls the data exchange to all connected slaves.
The slaves’ I/O data are mapped into memory inside the Master
according to the GSD configuration file.
The Profibus User Organization (PNO) registered the required
Profibus ID as: 0587h.
The GSD file is named: PD1_0587.GSD. It can be downloaded from
the Internet either vi a Allen Bradley Homepage under
http://www/ab.com/drives/Profibus/Index.html or P NO Homepage
under http://www/Profibus.com/downloads.html tha n GSD Libra ry
/ Rockwell Automation AG and Drives.
A micro floppy disk containing this GSD file is also available on
request from stock (RA catalog number: 160-GSD).
The PD1 Module utilizes two ten-position rotary switches (see figure
below) to configure the node address. These switches must be set to
match th e applic ati o n settings. Refer t o t he par ag ra p h s t ha t fo llow.

Setting the node address – S1 & S2
Before configuring the PD1 module the node address has to be set.
This is done via two rotary switches (S1, S2) on the PD1, which
enable address settings from 0-99 in decimal format.
The address is calculated in the following way:
Address = (S1 x 10) + (S2 x1)
Important: T wo ident ical node addre sses are not all owed within on e
network section.

Wiring the Drive Terminal Block
The 160 drive and 160-PD1 interface can be controlled on a network
in 2 different mod es.
[Input Mode] = 2
This mode is used where the dr i ve is controlled sol ely by the netw ork.
The 160-SSC drive requires, that a stop signal is present on the
hardware terminals, before the drive can be started.
Control
ether a wire bridge or a normally closed stopping device.
Fitting a stopping device (e.g. pushbutton) in place of the link,
can provide addition al lo ca l st op/emergency stop capability.
Important: Failure to link the stop command input, will result in the
[Input Mode] = 6
This mode is used whereby it is possible to control the drive across
the network or locally, by putting a switch on the Contro l Terminal
Block 3 (TB-3) pins 7 & 8.
When the switch is closed, the Frequency source comes from the
reference as defined by P59 - [Frequency Select]. As we are using
the 160-PD1, the reference is across the Profibus network.
Additionally the start command is active across the network.
Terminal Block 3 (TB-3) pins 7 & 8 need to be linked by
drive generating a fault, and inability to run accross a
network.
When the switch is open, the Frequency source comes from the
terminal block (analogue reference or potmeter), regardless of the
setting of P59 - [ Freque nc y Sel ect]. Additiona ll y the star t command is
controlled by the terminal block or keypad.

Powering Up the Drive
LED Indicators
After you have installed the PD1 Module, apply power to the drive
and to th e connected d ev ice. The R EADY LED should illuminate.
If it does not, refer to Chapter 8, Troubleshooting.
The PD1 Module has three LEDs (see figure below) which provide
module status.
READY LED
FAU LT LED
COMM LED
The LEDs are defined as follows:
•COMM – The COMM LED has four possible states:
Green (steady) Communication ok, data is exchanged.
Red (steady) Diagnostics failed at power-up
or fatal error.
Red (flashing) Profibus configuration fault (5 to 6 flashes).
Off No communication takes place / No power
For more details refer to Troubleshooting, Table 8.A
•FAULT – This LED tracks the fault status of the 160 Drive.
When no faults are present, the LED will be off. The LED will
illuminate (red) if a drive or an option board fault occurs.
•READY – The Ready LED will illuminate (green) whenever the
module is connected to the drive and power is applied.
4–2 Modes of Operation
Operation Modes
The PD1 Module has three modes of operation.
• Power-up mode
• Run mode
• Error mode
Power-up Mode
The following sequence of operation occurs:
1. During power-up, the READY LED illuminates green and the
FAULT and READY LED’s light up for a short periode.
2. The module reads and stores the rotary switch settings.
If the power-up sequence is successful, the module enters the run
mode and the COMM LED turns solid green as soon as data is
exchanged.
If the powe r -up sequ ence f ails, the COMM and FA ULT LED will stay
solid red and the module will enter the Error Mode (see below).
Run Mode
After a successful power-up, the PD1 Module enters the run mode
and operates as a slave device to a master d e v ice. In run mode, the
module:
• Accepts and responds to messages from the master on the
network.
• Monitors cable integrity an d t ransmissio n performance.
• COMM LED green if communication with the master is ok.
If an error is detected, the module enters Error Mode (see below).
Error Mode
Errors are indicated either by the COMM LED:
• Flashing red (5 to 6 flashs) signals a Profibus configuration fault
• Flashing red (other than 5 to 6 flashs) signals a fatal error
• Solid red signals that the power-up sequence failed
or the FAULT LED, which illuminates solid red at any 160 drive fault
or option board fault.
SSC160 drive faults are also indicated by the FAULT LED.
(See table 8.B).
Refer to Chapter 8 for details on how to recover from an error.

Also enables/disables the program keypad module input control.
Settings: must be set to either
2 = Program Keypad Module control or
6 = 2-wire TB3 Control/Keypad or Communication control
A contact closure on TB3 terminals 7 and 8 is required for the drive to respond to a
Run command.
Important: This parameter cannot be program med while the drive is running.
In addition, power must be cycled or P56 - [Reset Function] must be
set to 2 for the change to take effect.
[Frequenc y Sele c t]
Selects the source of the frequency command for the drive.
The reference to P58 - [Internal Frequency] is bipolar, so a positive reference gives
forward rotation, and a negative reference gives reverse direction.
Settings:must be set to 1 = internal freq. command from P58 - [Internal Frequency].
[RPM Scaling]
A scaling factor is required to interpret a speed reference in RPM at the [Maximum
Frequency] of the dri ve . The 160 Drive parameter P66 - [Preset Frequency 5] is
used by the PB1 Module for this purpose.
P66 = rRPM / rf
rf: required motor frequency to achieve rRPM
rRPM: final RPM at application output (e.g. speed at gear box output),
which will be displayed at Profibus Master
Application Speed [rpm] = Drive Output Frequency x P66 [RPM Scaling]
e.g. 1500 rpm = 50 Hz x 30 (4 pole motor) P66 = 30.0 (300)
900 rpm = 60 Hz x 15 (8 pole motor) P66 = 15.0 (150)
Gear Box 1:20: 75 rpm = 50 Hz x 1.5 (4 pole motor) P66 = 1.5 (15)
For network operation the P66 values in brackets are valid, which are ten times the
values for keypad operation.
If P66 - [RPM Scaling] is set to 0, speed reference may be sent via the network
directly in 1/10 of Hz.
e.g. SpeedRef [Hz] (Profibus) = 405 results in 40.5 Hz of output frequency.
Speed feedback is considered to be P01 - [Output Frequency],
which reflects the output frequency considering ramp rates.

Using the 160-PD1 on Profibus
The purpose of this chapter is to provide an example of the steps
necessary to use the 160-PD1 on a Profibus network. As Profibus is a
3rd party network, we will be using the SST-PFB-SLC scanner to act
as a master for Profibus, residing in an A-B SLC500 rack.
The SST scanner sends I/O messages periodically to a Bulletin
160-PD1 to start and stop the dri v e and co ntrol i ts spee d. Additio nally
the Bulletin 160-PD1 responds to these I/O message s b y sending
status messages and speed feedback back to the scanner. In this way
the ladder logic program in the A-B SLC500 PLC can control the
drive.
The Bulletin 160-PD1 a lso suppor ts a Prof ib us t ele gram which c an be
used to configure or read parameters from the drive .
This chapter contains the following information:
• How to create a Profibus network configuration frame.
Required Tools
• How to configure the SST-PFB-SLC scanner for use in a SLC
rack.
• A sample ladder logic program to control the Bulletin 160 SSC
using I/O messaging.
• A description of the Profibus te l egram.
• A sample ladder logic program to execute the telegram.
The SST-PFB-SLC scanner for the SLC500 is used in the examples
in this manual. However the concepts demonstrated in the examples
apply to any Profibus master.
The following too l s are needed to comp l et e this chapter.
• Bulletin 160 series C or higher, equipped with a 160-PD1
Profibus communication module
• SLC500 processor with a digital input card to issue start & stop
commands.
• SST-PFB-SLC scanner card, SST Configuration Tool and null
modem cable.

Follow the steps outlined below only when a new GSD file needs to
be added to the SST PROFIBUS Configuration Software Tool.
Typically this is only done once, after the software tool is initially
installed or before configuring the scanner for the network.
The software tool comes with standard data files. Additional data
files, such as the 160-PD1 GSD file, will need to be added to
configure the 160-PD1 in the scanner.
Click on the ”New Devic e” icon to add GSD files to the softw are
library tool.
An ”Add PROFIBUS devices” Applet window will appear.
Prompts for the location of the PROFIBUS data files to be added to
the library will follow.

The Profibus Telegram
The Profibus implementation of the 160-PD1 (as specified by the
GSD file) suppor ts 2 diff erent types of indepe ndent data tr ansmis sion.
The 2 words of control and status utilized above is the process data
cyclically transmitted / received, to start / stop the drive, provide a
reference, and get dr i v e feedb ack. This da ta trans mission pr ovide s th e
quickest means of communicating with the drive.
An additional parameter data channel is provided which is much
slower , w orking around the proc ess data cha nnels abov e, to r ead/write
parameters to a drive. This handles one parameter at a time, specified
by an index (parameter number) and a data channel.
In the example below, N7:41 contains the parameter number (Index),
and N7:4 2 contains a ny data that is to be written to the parameter
specified. These are copied to the Control words of the scanner for
action (N7:32 & 3). The command to read (80h) or write (A0h) is
copied from N7:43 & N7:44 and is shown on Rungs 4 & 5 on the
ladder above, as it forms the MSB part of the Logic Control Word.
This is an example of a read drive p arameter (all values in hex)
N7:40 is the Logic Control Word, where LSB = 5F (Drive running),
MSB = 80 (read operation).
N7:41 is the parameter number 2 = [Output Voltage].
N7:50 is the data from the drive on N7:22.
The value of D4h represents 212 Volts decimal.
N7:51 is a copy of the parameter number (Index) in the LSB
and the handshake if read operation was successful (MSB = 1).
This is another example of a read drive parameter
(all values in hex)
N7:40 is the Logic Control Word, where LSB = 5F (Drive running),
MSB = 80 (read operation).
N7:41 is the parameter number 8 = [Heatsink Temperature].
N7:50 is the data from the drive on N7:22.
The value of 45h represents 69 degrees C decimal.
N7:51 is a copy of the parameter number (Index) in the LSB
and the handshake if read operation was successful (MSB = 1).
Using the 160-PD1 on Profibus 6–17
This is an example of a write drive parameter (all values in hex)
N7:40 is the Logic Control Word, where LSB = 5F (Drive running),
MSB = A0 (write operation).
N7:41 is the parameter number 1Eh (30 decimal) = [Accel Time 1].
N7:42 is the data to be sent to the drive 14h (20 decimal),
which represents an Accel = 2.0 seconds.
N7:50 is not relevant when a write operation i s i n progress.
However it will provide 14h when revert to a read operation.
N7:51 is a copy of the parameter number (Index) in the LSB
and the handshake if read operation was successful (MSB = 1).

communicate through the PD1 Module to the drive.

Setting the Drive to Enab le Network Control
The 160 driv e must be configured to accept logic and speed
commands from the network. This can be done by configurin g two of
the 160 parameters:
1. Set P46 - [Input Mode] to a value of “2” or “6” as described in the
following Table. This will configure the drive to accept the logic
commands from the network.
Important: The d rive may be ope r a ted i n other mo des as long as
the Profib us Master provides an Enable command
(control w o rd = 0x6)
2. Set P59 - [Frequency Select] to “1.” This will configure the drive
to accept speed commands fro m the network .
3. Set P66 - [RPM Scaling] according to rated namepla te s peed.
Changing the above parameters can be done with the 160 Keypad
Module or configuration software such as DriveExplorer.
Important: For a new Input Mode to take af fect, dr i ve pow er must be
cycl ed o r para mete r P56 - [Reset Functions] must be set to
“2” instead.
Setting the Node Address
The node address on the PD1 Module should be configured to the
desired setting for the network. After configuration, install the PD1
Module into the 160 Drive as explained in Chapter 3.

Troubleshooting
The purpose of this chapter is to help you troubleshoot your P D1
Module.
ATTENTION: Servicing energized industrial control
equipment can be hazardous. Electrical shock, burns, or
!
unin tent ional a c tuation o f controlled industrial equ ipment
may cause death or serious injury . Follow th e safety-rel ated
practices of NPFA 70E, Electrical Safety for Employee
Workplaces, when working on or near energiz ed equipment.
Do not work alone on energized equipment.
ATTENTION: Do not attempt to defeat or override fault
circuits. T he cause of a fault indicati on must be determined
!
and corrected before attempting operation. Failure to
correct a dri ve or system malfunct ion may result in personal
injury and/or equipment damage due to uncontrolled
machine system operation.
