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
