Profibus-DP Configuration
From Profibus-DP point of view the Profibus-DP Slave (PDPS) node
is configured based on a data file (*.GSD) which contains 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 via Allen Bradley Homepage under
http://www/ab.com/drives/Profibus/Index.html or PNO Homepage
under http://www/Profibus.com/downloads.html than GSD Library
/ 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).
Module Configuration Switches
The PD1 Module utilizes two ten-position rotary switches (see figure
below) to configure the node address. These switches must be set to
match the application settings. Refer to the paragraphs that follow.

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: Two identical node addresses are not allowed within one
network section.

Installation and Wiring
Wiring the Drive Terminal Block
3–5
The 160 drive and 160-PD1 interface can be controlled on a network
in 2 different modes.
[Input Mode] = 2
This mode is used where the drive is controlled solely by the network.
The 160-SSC drive requires, that a stop signal is present on the
hardware terminals, before the drive can be started.
Control Terminal Block 3 (TB-3) pins 7 & 8 need to be linked by
ether a wire bridge or a normally closed stopping device.
Fitting a stopping device (e.g. pushbutton) in place of the link,
can provide additional local stop/emergency stop capability.
Important: Failure to link the stop command input, will result in the
drive generating a fault, and inability to run accross a
network.
[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 Control 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.
When the switch is open, the Frequency source comes from the
terminal block (analogue reference or potmeter), regardless of the
setting of P59 - [Frequency Select]. Additionally the start command is
controlled by the terminal block or keypad.

Installation and Wiring
Wiring the PD1 Ground
Terminal
In addition to the ground connections shown in Appendix C of the
160 SSC manual, the ground terminal at the bottom of the PD1
module must be solidly connected (and as short as possible) to the
output ground terminal at TB2 of the 160 SSC drive, as shown in

* Termination is required at both ends of the network.
The Profibus master might offer on-board termination.
Make sure that other Profibus slaves with on-board termination are set
up correctly.
Profibus Network Termination
The network must be terminated at the first (network master) and the
last PD1 module. A bus cable connector with an internal resistor
network must be used as no internal termination is provied on the
PD1 module. (Refer to Figure 3.7).

Modes of Operation
Chapter 4 contains the following information:
• Powering up the drive with the PD1 Module installed
• LED Indicators
• Operation Modes
Powering Up the Drive
After you have installed the PD1 Module, apply power to the drive
and to the connected device. The READY LED should illuminate.
If it does not, refer to Chapter 8, Troubleshooting.
LED Indicators
The PD1 Module has three LEDs (see figure below) which provide
module status.
READY LED
FAULT 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 power-up sequence fails, the COMM and FAULT 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 device. In run mode, the
module:
• Accepts and responds to messages from the master on the
network.
• Monitors cable integrity and transmission 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.

[Parameter Name] and Description
[Input Mode]
Configures the TB3 control inputs for various 3-wire or 2-wire control schemes.
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 programmed 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.
[Frequency Select]
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 drive. The 160 Drive parameter P66 - [Preset Frequency 5] is
used by the PB1 Module for this purpose.
P66 = rRPM / rf
rf:
rRPM:
required motor frequency to achieve 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.
!
ATTENTION: Unpredictable motor speed can cause death,
injury or equipment damage. Do not use P66 as the [Preset
Frequency 5] function via control terminal wiring.

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 drive and control its speed. Additionally
the Bulletin 160-PD1 responds to these I/O messages by 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 also supports a Profibus telegram which can be
used to configure or read parameters from the drive.
This chapter contains the following information:
•
How to create a Profibus network configuration frame.
•
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 telegram.
•
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.
Required Tools
The following tools are needed to complete 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.

Installing the 160-PD1 GSD File
in the Software Tool Library
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 Device” icon
to add GSD files to the software
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.

In order that the scanner can operate in the SLC rack, first the SLC
rack configuration needs to be set up. Using RSLogix500 in an offline
state, create a new program and setup the I/O configuration as shown.
The I/O configuration utilizes a digital input card in slot 1 to provide
commands to start & stop the drive etc.
The SST-PFB-SLC scanner card is dropped into slot 2 using ”Other”
from the cards available column. You are required to specify the card
with an ID Code = 13635.
Please note that the example configuration contains an additional card
in slot 3 which is not used in the following example.
With the card in slot 2 selected, click on Adv Config to specify the
number of words used in the card.

SLC Ladder Logic Example
6–11
Profibus scanners vary from manufacturer to manufacturer, in how the
bytes are ordered in a word. The SST-PFB-SLC scanner card receives
/ transmit data with the Most Significant Byte (MSB) first and the
Least Significant Byte (LSB) second. This is opposite to how we read
/ write information in the SLC. This section of program below
reverses the high / low byte order using the SWP instruction.

Once the bytes have been swapped, the control and status words can
be manipulated as per normal.
Note: If your scanner does not order the MSB first, LSB second, but
the other way around, then the program above can be omitted.

The Profibus Telegram
The Profibus implementation of the 160-PD1 (as specified by the
GSD file) supports 2 different types of independent data transmission.
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 drive feedback. This data transmission provides the
quickest means of communicating with the drive.
An additional parameter data channel is provided which is much
slower, working around the process data channels above, to read/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 N7:42 contains any 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 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 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 is in 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).

Controlling the Drive
Controlling the 160 Drive from a programmable controller is
accomplished using the Telegram described in Chapter 5 to
communicate through the PD1 Module to the drive.
Setting the Drive to Enable
Network Control
The 160 drive must be configured to accept logic and speed
commands from the network. This can be done by configuring 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 drive may be operated in other modes as long as
the Profibus Master provides an Enable command
(control word = 0x6)
2. Set P59 - [Frequency Select] to “1.” This will configure the drive
to accept speed commands from the network.
3. Set P66 - [RPM Scaling] according to rated nameplate speed.
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 affect, drive power must be
cycled or parameter 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.

ATTENTION: Servicing energized industrial control
equipment can be hazardous. Electrical shock, burns, or
unintentional actuation of controlled industrial equipment
may cause death or serious injury. Follow the safety-related
practices of NPFA 70E, Electrical Safety for Employee
Workplaces, when working on or near energized equipment.
Do not work alone on energized equipment.
ATTENTION: Do not attempt to defeat or override fault
circuits. The cause of a fault indication must be determined
and corrected before attempting operation. Failure to
correct a drive or system malfunction may result in personal
injury and/or equipment damage due to uncontrolled
machine system operation.
Setup
Make sure parameters P46, P59, P66 and P116 have been set
according to chapter 5.
LED Indicators and
Troubleshooting
The PD1 Status LEDs can help you troubleshoot the module in the
event that problems occur. Refer to the paragraphs that follow for
details.
Status LEDs
READY LED
The green READY LED will illuminate whenever the PD1 Module is
connected to the drive and power is applied.

Diagnostics failed at power-up
or Fatal Error
What To Do:
Check Power Supply,
Network Configuration
No action required.
Cycle power to the drive. If problem
persists, exchange PD1 Module
flashing A cascade of 5 or 6 flashs means
Profibus configuration fault.
Check Network Configuration,
Profibus Master Setup and
SSC160 Setting (Section 5)
Any other flashs indicate Fatal Error Exchange PD1 Module
FAULT LED
When the FAULT LED lights red, a drive fault (including Fatal Error),
or an option board fault is present. Drive fault codes can be read by
accessing drive parameter P07 - [Last Fault].
