The PROFIBUS Master protocol driver exists as a single port implementation.
The driver can be configured as a Class 1 and Class 2 PROFIBUS Master to
interface with other PROFIBUS slave devices. The unit is also used for
configuration of the nodes on the PROFIBUS network. It provides access to
standard and extended diagnostic information, as well as freeze/sync capability,
Acyclic Communication (DPV1, Class 1 and 2), and Alarm Handling (DPV1). The
PROFIBUS Master port can be used to continuously interface with PROFIBUS
slave devices over a serial communication interface (RS-485).

Functional Overview PDPMV1 ♦ ProLinx Gateway
Protocol Manual PROFIBUS DPV1 Master
1.1 About the PROFIBUS Protocol
PROFIBUS (Process Field Bus) is a widely used, open-standards protocol
created by a consortium of European factory automation suppliers in 1989.
PROFIBUS is a Master/slave protocol. The Master establishes a connection to
the remote slave. When the connection is established, the Master sends the
PROFIBUS commands to the slave.
The ProLinx PDPMV1 gateway unit acts as an input/output module between
devices on a PROFIBUS DP network and any other communication protocol. The
gateway uses an internal database to send data and mailbox requests and
responses to all PROFIBUS slaves on the PROFIBUS DP network.
PROFIBUS supports a variety of network types. The network type supported by
the PLX-PDPMV1 gateway is PROFIBUS DP version 1.0, which is designed for
remote I/O systems, motor control centers, and variable speed drives.

1.3.2 Bus Access
Two different bus access procedures handle the various communication
requirements for the PROFIBUS DP-V1 Master topology:
Token Passing
Polling
Page 12 of 157 ProSoft Technology, Inc.
March 23, 2011
PDPMV1 ♦ ProLinx Gateway Functional Overview
PROFIBUS DPV1 Master Protocol Manual
1.3.3 Token Passing
Token passing ring is the basis for communication between the more complex,
active stations. All stations have the same rights in that a token is passed from
station to station in a logical ring. The token is passed to each station with a
maximum, definable token cycle time. A station is given transmission rights for
the duration of time that it has the token.
1.3.4 Master/Slave Polling
Master/slave polling guarantees a cyclic, real-time based data exchange
between the station with transmission rights, the active station, and its
subordinates, the passive stations. In this case, the Master is able to pass data to
the slave and/or receive data. The services in layer 2 (field-bus data link in ISOOSI reference model) organize this communication.

Protocol Manual PROFIBUS DPV1 Master
1.4 Communication Types
In addition to point-to-point data transfer, the PROFIBUS protocol can also
handle the following types of communication.
Broadcast communication: An active node sends an unacknowledged
message to all other nodes (Master and slaves)
Multicast communication (control instructions): An active node sends an
unacknowledged message to a group of nodes (Master and slaves)

PDPMV1 ♦ ProLinx Gateway Functional Overview
PROFIBUS DPV1 Master Protocol Manual
1.5 Master/Slave Communication Phases
The communication between the Master and the slaves takes place in the
following phases:
Parameterization and configuration phase
Usable data transfer phase
Before a DP slave can be integrated into the usable data transfer phase, the
parameterization and configuration phase runs a device identification test that
verifies that the planned configuration matches the actual device configuration for
each slave in the PROFIBUS network. The test verifies that:
The device is actually there
It is the right type of device
The station address set on the device matches the station address in the bus
configuration
The formats, telegram length information, and bus parameters are correct
and
The number of configured inputs and outputs is correct

Functional Overview PDPMV1 ♦ ProLinx Gateway
Protocol Manual PROFIBUS DPV1 Master
1.6 Gateway Internal Database
The internal database is central to the functionality of the gateway. This database
is shared between all the ports on the gateway and is used as a conduit to pass
information from one device on one network to one or more devices on either
connected network. This permits data from devices on one communication port
or network to be viewed and controlled by devices on another port or network.
In addition to data from the Master and slave ports, status and error information
generated by the gateway can also be mapped into the internal database.

2.2.5 Input Byte Swap
YES or NO
This parameter determines if the bytes in the PROFIBUS Input Data area are
swapped before being stored in the gateway memory database. If the parameter
is set to NO, no swapping will be applied. If the parameter is set to YES, the order
of bytes in each word will be swapped before being stored in memory.
Example:
With Input Byte Swap set to NO, incoming order is unchanged - ABCDEF
With Input Byte Swap set to YES, each byte pair is swapped - BADCFE
2.2.6 Output Byte Swap
YES or NO
This parameter determines if the bytes in the PROFIBUS Output Data area are
swapped before being transmitted to slaves on the PROFIBUS network. If the
parameter is set to NO, no swapping will be applied. If the parameter is set to
YES, the order of bytes in each word will be swapped before being transmitted.

2.2.7 Mailbox Register
0 to 3700, -1 to disable
Enter the database register for DPV1 mailbox messages, or -1 to disable mailbox
messages.
Mailbox messages can be sent through the database to the PROFIBUS Master.
This functionality requires 290 registers of the database. The map of the
database area utilized for this purpose is as follows.
Offset Description
0 This is the handshake word used to tell the PROFIBUS driver when a new acyclic
message is ready to send. If the value at this location is zero (0), no message will be
sent. If the value is not zero, then the PROFIBUS driver will send an acyclic
message using the contents of words 1 through 144. This handshake word should
be set to a non-zero value only after the complete acyclic message is stored in
offsets 1 to 144. After the PROFIBUS driver has added the acyclic message to the
queue, this register will be set to zero (0), so that the message is not repeated and to
indicate that a new acyclic message may be prepared.
NOTE: It would be a good practice to check the value of word 145 to be sure it is set
to zero (indicating that no acyclic messages are awaiting processing) before setting
this word to a non-zero value, triggering an acyclic message. This will help avoid
acyclic data collisions and data loss.
1 to 144 This area holds the acyclic message bytes to send. Please refer to Mailbox
Messaging (page 75) for the format of this data area.
NOTE: The header words (first 32 bytes) are stored in little-endian format and the
gateway will change the order to big-endian format before sending.
145 This handshake word indicates when a new acyclic response message has been
received by the PROFIBUS driver. If the value is zero (0), no response message has
been received. If the value is non-zero, a response message has been received and
stored in words 146 to 289. This data should be transferred by the other gateway
protocol for external processing. After the acyclic message has been externally
processed, a message should be returned through the other protocol that sets this
address to zero, to indicate readiness to receive and process a new acyclic response
message.
146 to 289 This area holds the acyclic message response bytes. Please refer to Mailbox
Messaging (page 75) for the format of this data area. The header words (first 32
bytes) are stored in little-endian format to make it easier to use.
Alarm acyclic messages are sent from the PROFIBUS driver to the database if
this feature is enabled by entering a valid database register in the configuration
file. This feature requires 145 database registers. The format of the data area is
as follows.
Offset Description
0 This is the alarm handshake word. If the value is not zero (0), alarm data is present
in the words 1 through 144. This register should be set to zero after the alarm is
process, so another alarm can be passed through the database. If this register is
zero (0), the database area is ready to receive a new alarm message.
1 to 144 This area holds the alarm acyclic message received by the PROFIBUS Master
device. Please refer to Mailbox Messaging (page 75) for a description of this acyclic
message. The header (first 32 bytes) of the message is stored in little-endian format

Enter the database register start location for DPV1 slave diagnostics messages,
or -1 to disable slave diagnostics.
When this register is enabled, the gateway will automatically place 378 words of
collected slave diagnostic data into the specified database start register.
Each slave requires 3 words of data. Data is gathered for slaves 0 to 125. The
application will poll for a new slave every 100 milliseconds.
2.2.9 Alarm Register

2.2.11 Minimum Command Delay
0 to 32767

2.2.12 Response Timeout
0 to 5000 milliseconds
Number of milliseconds to wait for response to command. The value is set
depending upon the communication network used and the expected response
time of the slowest device on the network.
2.2.13 Watchdog Register
The Watchdog function allows the gateway to monitor a database register, the
Watchdog Register, to check for loss of communication with the non-PROFIBUS
communication protocol. If this function is used, the other gateway protocol is
expected to change the value in the Watchdog Register at an interval less than
the amount of time specified in the Watchdog Timeout parameter. If the value in
the Watchdog Register does not change within this amount of time, a
communication loss is assumed and the Watchdog function will set the
PROFIBUS outputs to the default value specified in the Watchdog Reset Value
parameter. To disable this function, set this parameter to a value of -1.

2.5 Configuring the PROFIBUS DP Network
To configure your PROFIBUS DP network you must perform four tasks:
1 Install any PROFIBUS slave-specific device configuration files, typically
called .GSD files (page 52).
2 Configure the ProLinx PROFIBUS DP Master (page 52).
3 Configure the PROFIBUS slaves.
4 Print the Unity Passthru Memory Map.
2.5.1 Installing the GSD Files
ProSoft Configuration Builder (PCB) uses PROFIBUS slave device definition files
(GSD files) to obtain basic configuration information about the PROFIBUS slaves
you add to the network. The GSD configuration files identify the slave’s
capabilities so that the PDPMV1 can communicate with it correctly. Slave device
manufacturers provide the GSD files for the equipment they make. Slave device
files sometimes come in various languages. When a manufacturer provides slave
device files in several languages, it is a common practice to use the third letter of
the file extension to indicate the language used in the file. For instance:
o
.GSD is the most commonly used file extension and will usually be in
either English or German
o
.GSE will usually be in English
o
.GSS will usually be in Spanish
o
.GSF will usually be in French
o
other combinations may also be seen, as well as other languages using
the letters indicated above
Follow these steps to install the GSD file or files for your slave device or devices.
Tip: GSD configuration files for popular PROFIBUS slaves and ProSoft Technology solutions are
included with PCB. Before installing GSD files, browse the list of available slaves in the Tree View
window to see if GSD files for your slave are already installed.
GSD files are often both model number specific as well as model revision specific. Just because
you may have an older GSD file from a manufacturer for the particular make and model of your
slave device does not guarantee it will work for a newer revision of that device. Be sure you obtain
from the device manufacturer the correct GSD file or files for your PROFIBUS slave or slaves.

2.5.2 Configuring the PROFIBUS Slaves
There are two essential steps to configuring a slave:
1 Add the slave in ProSoft Configuration Builder (PCB) as a device connected
to the PROFIBUS Master, specifying the slave address and any necessary
input and output configuration. Download the PROFIBUS Master
configuration to the PDPMV1 module.
2 Configure the slave (using PCB or the configuration tool supplied by the
manufacturer, for some PROFIBUS slaves). Verify that the slave address
configured in the slave module matches the slave address configured in PCB.
Download the PROFIBUS Slave configuration to the slave module.
Scanning for Slaves Manually
Important: The GSD file for this example is not included on the ProLinx Solutions CD-ROM, and is
used for illustrative purposes only. You can download a variety of example GSD files from the
PROFIBUS Trade Organization website at www.profibus.org, or from the manufacturer's website
for your PROFIBUS slaves.
The following steps describe how to add and configure a Siemens EM 277 I/O
chassis to the PROFIBUS network. The configuration information (.GSD file) for
this device must be installed according to the procedure found in Install the GSD
Files (page 52). Most other PROFIBUS slaves can be configured in a similar
manner.

For this example, we will configure 8 words of input and 32 words of output.
These input and output words are assigned to addresses within the
gateway's internal database.
For each new slave added to the PROFIBUS network, ProSoft Configuration
Builder automatically converts the input/output byte addresses to word
input/output addresses.
Tip: To make it easier to view the data from individual slaves, you can create a spreadsheet with
all added slaves and input and output data offsets, or you can view and print the data map.

ProSoft Configuration Builder automatically assigns a PROFIBUS address to
each new slave. The slave address assignment begins at address 3 for the
first slave added to the network (addresses 0, 1, and 2 are reserved for use
with PROFIBUS Masters), and is incremented by 1 for each new slave added
to the network. You may, however, assign any address, 0-125 to any Master
or slave node as long as you do not assign the same address to more than
one device. You can change the address in the C

tab of the Slave
properties dialog box. ProSoft Configuration Builder will not allow you to
assign a PROFIBUS address that is already in use by another device on this
network.

Using The Autoscan Feature
The concept of Automatic network scanning means that the user can instruct the
Bus Configuration window to automatically gather information about slaves that
are connected to the network. When the scan is completed the user can adopt
the detected slaves to the bus configuration and download to the Master.
This is a quick way to get a network up and running. However, one should be
aware that it is not guaranteed that any particular slave will enter data exchange
since the user parameter data might not match. This is especially obvious if no
associated GSD-file is found during the network scan, this means that no user
parameter data would be sent to the slave.

When the download is completed, the PROFIBUS Master Configuration window
will initialize the Master to operate as a Class 2 Master only. In this mode it is
possible to initialize the Master even if the database does not contain any slaves.
After successful initialization, the PROFIBUS Master Configuration window will
issue the following mailboxes in order to gather information about the connected
slaves:
1 1. Send FB_APPL_GET_LIVE_LIST in order to detect connected slaves,
2 2. Send FB_APPL_GET_SLAVE_DIAG (external request) to all devices
identified as slaves according to the Live list.
3 3. Send FB_APPL_GET_SLAVE_CONFIG to all devices identified as slaves
according to the Live list.
When the information is collected the PROFIBUS Master Configuration window
will find a matching GSD-file and extract information from it. Refer to the
flowchart below for this sequence:

GSD Selection Algorithm
If two or more matching GSD-files are found, the first one found should be
selected. The other compatible files should be stored so that the user can select
one of them instead. If the user selects another GSD-file, the PROFIBUS Master
Configuration window will run through the Module Selection Algorithm (described
below) again.
Module Selection Algorithm
The algorithm used to find modules in the GSD based on the Identifier byte(s) is
as follows:
Select the module that matches the largest number of Identifier bytes. If the GSD
contains two or more modules with the exact set of Identifier bytes, use the first
module found.
Example:
If a slave responds with identifier bytes: 0x11, 0x21, 0x31 and that the associated
GSD-file contains five modules: “A” = 0x11, “B” = 0x21, “C” = 0x31, “AB” = 0x11,
0x21 and “BC” = 0x21, 0x31. The PROFIBUS Master Configuration window will
then select modules "AB" and "C".
Note: If no matching module is found in the GSD, The PROFIBUS Master Configuration window
will display the identifier byte(s) instead.
Network scan window
The information extracted from the GSD-file(s) will be displayed in the Network
scan window.

In this column the node address of the slaves will be displayed. Found slaves
should be listed in ascending order according to their node addresses.

Special address 126 -Set Slave address:
If a slave with node address 126 is detected during the network scan, the
PROFIBUS Master Configuration window will display the address in red color. It
will not be possible for the user to adopt the slave to the configuration since it is
not allowed to exchange data with devices having this address. The check box in
the Select column will be grayed out.
To be able to adopt a slave with address 126 the user must first assign a valid
address by clicking the icon next to the node address. By doing so the Set Slave
Address dialog box is started.

In This Chapter
Mailbox Message Queuing .................................................................... 76
Special Function Mailbox Messaging Commands ................................. 77
Mailbox Messaging Error Codes ........................................................... 99
The PDPMV1 PROFIBUS DP Master uses a process called Mailbox Messaging
to exchange parameter data between the processor, Master, and slave devices.
This process provides a way to encapsulate and prioritize commands and data
sent between the PROFIBUS Master and slaves.
The PROFIBUS DP-V1 protocol specifies two types of data transmission
messages (telegrams): Cyclic Data Telegrams and Acyclic Data Telegrams.
Cyclic data communication is the exchange of normal slave input and output (I/O)
data and is handled automatically by the Master in a defined, recurring,
deterministic sequence based on the configuration you create in ProSoft
Configuration Builder (PCB).
Acyclic communication extends data communication beyond normal I/O data to
allow moving field device parameterization and calibration data over the bus
during runtime and to allow for extended diagnostics and alarm messages.
Acyclic data telegrams are transmitted in the gaps between cyclic data telegrams
and, therefore, have a lower priority and get less bandwidth than cyclic data.
Mailbox Messaging commands are incorporated into the sample ladder logic.
Mailbox messages and responses to mailbox messages are stored in mailbox
data types.
The following chapter discusses these features in more detail.

3.1 Mailbox Message Queuing
The PDPMV1 gateway operates asynchronously on the Mailbox Messages and
as such provides for the queuing of the messages as they are received. The
queue sizes used in the gateway are as follows:

3.1.1 Queue Timeouts
The PDPMV1 gateway will only allow a message to stay in a queue for up to 10
seconds. If the PROFIBUS Master (for output messages) or the processor (for
input and alarm messages) has not successfully received a message within 10
seconds, the gateway will clear the message out of the queue.
gateway will queue by type of message. Note
that status of the queues can be monitored
via the Queue Message Count values.

3.2 Special Function Mailbox Messaging Commands
The PDPMV1 gateway supports some extended PROFIBUS functions, using a
mailbox data exchange mechanism implemented in the gateway.
The PDPMV1 gateway supports the following special functions through this
mailbox messaging scheme.
Important Note: When you use the database to send your mailbox command, the application
places a value of B0 into the first byte of the Message ID word. This value identifies the mailbox
command issued, and differentiates the source of the message: either the database or the
command structure. You should use a message ID value between 1 and 255 in the message ID
header.

Protocol Manual PROFIBUS DPV1 Master
3.2.2 Mailbox Message: Set Slave Mode
In addition to station-related user data transfer, which is executed automatically,
the Master can send control commands to a single slave, a group of slaves, or all
slaves simultaneously. These control commands are transmitted as multicast
commands. This permits use of sync and freeze modes for event-controlled
synchronization of the slaves.
The slaves begin sync mode when they receive a sync command from their
assigned Master. The outputs of all addressed slaves are then frozen in their
current state. During subsequent user data transmissions, the output data are
stored on the slaves, but the output states remain unchanged. The stored output
data are not sent to the outputs until the next sync command is received. Sync
mode is concluded with the unsync command.
Similarly, a freeze control command causes the addressed slaves to assume
freeze mode. In this operating mode, the states of the inputs are frozen until the
Master sends the next freeze command. Freeze mode is concluded with the
unfreeze command.
Note 1: It is only possible to send control commands when operating mode is either CLEAR or
OPERATE.
Note 2: Not all slaves support this feature. Refer to the documentation for the actual slave for more
information.

Group Select
Range 01h to FFh (Bit Coded)
This parameter determines which group to address. Refer to the following
example:
b7 b6 b5 b4 b3 b2 b1 b0
Group 8 Group 7 Group 6 Group 5 Group 4 Group 3 Group 2 Group 1
Example: To address Group 1, 2, and 4, the Group Select value should be D0h.
If an individual slave should be addressed, the correct group selection must also
be made, because the slave will ignore the message if it does not belong to the
requested group(s).
What group(s) a slave belongs to is determined during network configuration,
and is downloaded during initialization to each slave via the PROFIBUS telegram
"Set_Prm".
