1. Profibus DP Description
The Profibus DP driver allows the FieldServer to transfer data to and from devices using
Profibus DP protocol. The Communications Adapter card is included with the FieldServer. The
FieldServer can function as either a Master or a Slave on the Profibus Network.
When acting as a DP Master, the FieldServer requires a Profibus master configuration file in
addition to its own configuration file. The Profibus master configuration file
(bridge.bss/bridge.2bf) describes the operating network, and the FieldServer configuration file
(config.csv) describes the data that will be accessed within the Profibus slaves. As slaves are
added or removed from the Profibus network, the Profibus master configuration file will need to
be updated. The Profibus master configuration is created using a Profibus configuration tool.
The tool provided on the SST CD can be used to create this file.
As a slave, the Profibus DP driver allows the FieldServer to be a single slave station to another
master. This slave is capable of transferring 244 bytes of input and 244 bytes of output to the
other master. If it is necessary to transfer more data to a Profibus master, then the Profibus
DPMS driver and adapter card will be necessary. For Slave applications, the Profibus master
configuration file is not used, and only the FieldServer configuration file will be used to set the
FieldServer’s Profibus Slave station address and buffer sizes.
To connect to the Profibus network, the FieldServer has been equipped with a 5136-PFB-ISA
card. This card has a standard DB-9 Profibus port that will accommodate a DB9 (Male)
Profibus connector (supplied) and drop cable (not supplied).
The 5136-PFB-ISA card requires firmware (PFBDP.SS1) which will be factory installed onto the
FieldServer prior to shipment.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.
