Profibus X30 DP Slave Description
The FieldServer Profibus DP Slave driver can be used to emulate a single Slave station on a
Profibus network. DP Masters can open a connection of up to 244 Bytes of Input and 244 Bytes
of Output data, but not exceeding a combined total of 416 Bytes to the FieldServer. The
FieldServer can be added to the Profibus network with the use of the supplied GSD file for the
ANYBUS card. Connection to the Profibus network is via a DB9 port on the ANYBUS card.

* +5V BUS and GND BUS are used for bus termination. Some devices, like optical transceivers
(RS485 to fibre optics) might require external power supply from these pins. RTS is used in some
equipment to determine the direction of transmission. In normal applications only A-Line, B-Line
and Shield are used.

Configuring the FieldServer as a Profibus DP Server
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
Configuration Manual. The information that follows describes how to expand upon the factory
defaults provided in the configuration files included with the FieldServer (See “.csv” filesprovided
with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a Profibus DP Master.
The configuration file tells the FieldServer about its interfaces, and the routing of data required.
In order to enable the FieldServer for Profibus communications, the driver independent
FieldServer buffers need to be declared in the “Data Arrays” section, the FieldServer virtual
Node(s) needs to be declared in the “Server Side Nodes” section, and the data to be provided to
the Clients needs to be mapped in the “Server Side Map Descriptors” section. Details on how to
do this can be found below.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

Appendix A.2. Setting the FieldServer’s Profibus Station Address
The Station Address can be set in the FieldServer’s CSV file using the
System_Station_Address, (refer to Section 4.1), or it can be set with the two rotary switches
as indicated on the connection diagram. The left switch selects the left decimal digit and the
right switch the right decimal digit of the Station Address.
Note that the software setting with the System_Station_Address overrides the hardware
setting with the rotary switches.
Appendix A.3. Understanding Driver Communication Statistics
When connecting with Ruinet to the FieldServer, there are communication statistics
displayed on the Connection, Node and Map descriptor screens for the Profibus DP driver.
The Transmit (Tx) message count indicates the number of times the driver wrote output
data into the Profibus hardware card’s output buffers for transmission on the Profibus
network. It does not indicate the actual number of transmissions on the Profibus network.
The Receive (Rx) message count indicates the number of times the driver read input data
from the Profibus hardware card’s input buffers. It does not indicate the number of actual
messages received on the Profibus network.

Appendix B. Troubleshooting
Appendix B.1. FieldServer as a Profibus Slave
If no communication is being experienced between a Profibus Master and a FieldServer
Profibus Slave, check for the following most common issues:
•
The Node_ID must match the System_Station_Address in the configuration
o Having these two parameters match in the configuration tells the FieldServer that
the buffer referenced in the Node_ID refers to the buffers in the Profibus card
attached to the FieldServer.
•
The gsd file must match the FieldServer hardware being used
o FieldServer offers several hardware platforms that support Profibus. Each
hardware platform requires its own gsd file. Ensure that the gsd file being used
is the correct file for the hardware platform in use.
o The gsd file can be opened with a text editor. The Vendor and model name can
be checked in this file. For the FieldServer X30 Profibus Slave, the Vendor is
“HMS Industrial Networks AB”, and the Model Name is “ANYBUS-S PDP”. The
current revision is 1.5, which uses Hardware revision 1.6 and software release
1.2.
•
The byte count for the gsd profile must match the byte count configured in the
FieldServer
o The gse being used is either going to allow the Client (via the network
configuration tool) to select the bytes to be used, or the byte make-up will be
fixed and specified in the gse. Either way, the largest byte offset used by the
Client must match the largest byte offset configured in the FieldServer.
o When selecting byte count with a network configuration tool, the total amount of
bytes/words/bits setup per Input/Output buffer in the FieldServer configuration
Map Descriptors must match those selected in the network configuration tool
otherwise a connection length mismatch will occur and the connection will not be
established. The FieldServer shows the connection size it expects on the F
(driver message) screen in the RUI utility in order that this value may be checked
against the network configuration tool.
•
•
The direction of the communications (Input/Output Buffer) may be incorrectly configured.
o Buffer names can be confusing, especially when looking at the Slave. The
buffers are named according to their direction of communication in the Master.
Hence, an Input buffer in the Slave will write data to the Master, and data will be
received from the Master in the output buffer.
o Remember that as a Slave, the FieldServer will have to write data into the input
buffer (function=wrbc), and read data from the output buffer (function=rdbc).
The Profibus card may be faulty.
o If this is the case, then there will be an error message in the FieldServer RUI
error screen indicating that the card could not be reached. Check for this
message. If it is there, try opening up the FieldServer and re-seating the card. If
this does not help, contact FieldServer Technical support for jumper settings on
the card, and further possible troubleshooting or return authorization.

•
The Data Type/Offset/Length combination may be incorrectly set up
o In the FieldServer configuration, the Offset Parameter refers to the buffer offset in
bytes (starting at 0), regardless of data type.
o The Length parameter always refers to length in items, which means Float data
will be the number of float values, Word data will be the number of words, etc.
