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.

several slaves.
The following table shows the most important features of PROFIBUS DP-V1
Master:
Standard EIN 501 70
DIN 19245
Transmission equipment (Physical) EIA RS-485
IEC 1158-2 (through link or coupler)
Fiber Optic Cable (not available)

Number of nodes on the bus Max: 32 with no repeaters
Max: 125 with 3 repeaters in 4 segments
1.3.1 How Cable Length Affects Communication Rate
Max Bus Cable Length Per Segment Baud Rates (for 12 Mbps cable)
1.2 km 9.6 kbit/sec
1.2 km 19.2 kbit/sec
1.2 km 93.75 kbit/sec

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)

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.
Example:
With Output Byte Swap set to NO, outgoing output order is unchanged -
ABCDEF
With Output Byte Swap set to YES, each output byte pair is swapped -
BADCFE

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

2.2.8 Slave Diagnostics Register
0 to 3600, -1 to disable
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
0 to 3900, -1 to disable
Enter the database register for DPV1 alarm messages, or -1 to disable alarm
messages.
2.2.10 Status Data Register
0 to 3900, -1 to disable
Enter the gateway memory database register for DP-V1 status data messages,
or -1 to disable status data messages.
2.2.11 Minimum Command Delay
0 to 32767
Minimum number of milliseconds between each command.
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.

2.2.14 Watchdog Timeout
Sets the period of time (in 0.1s increments) for the gateway to wait for
communication loss detection. For example, set this parameter to 100 to set a
waiting period of 10 seconds. To disable this function, set this parameter to a
value of -1.
2.2.15 Watchdog Reset Value
Sets the value that will be sent to the PROFIBUS output byte registers upon
communication loss as detected by the Watchdog function. To disable this
function, set this parameter to a value of -1.
