FS-8700-20 Profibus DP Driver Manual Page 3 of 22 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

Hardware Connections The FieldServer is equipped with a SST 5136-PFB-ISA interface card, which has a standard Profibus DB-9 interface available for connection to the Profibus network. If the FieldServer is located at an end of the network, termination will be required. For more information on Profibus cables and connections, please refer to the documentation provided on the SST CD. WARNING: Improper cabling can cause physical

Profibus Master Configuration If using the FieldServer as a Profibus master, provide a configuration file to fully describe the network connected to the FieldServer. The Profibus driver will accept a 2BF file or a BSS file. The 2BF file is created using COM PROFIBUS from Siemens. The BSS file is created using the SST Profibus Configuration tool. These files can be loaded onto the FieldServer using the FieldServer RUI utiliti

Creating the Network Configuration File for the Master The output of this procedure is a bridge.bss file that has to be downloaded to the FieldServer. 1) Start the SST Profibus Network Configuration Tool and drag the 5136-PFB-ISA MASTER [Rev 1.3] Master device into the right-hand window pane. 2) Set the Station to be the same as defined under System_Station_Address in the config.csv file. Click OK to close the Master

Choose a highest Station on the network if you wish to enhance performance, which will prevent the Master from scanning non-existant Stations. Click OK to complete the network configuration. 5) Drag your Slave devices onto the right window pane and configure them as per manufacturer’s instructions. Choose a unique Station ID for each Slave.

DP_Buffer Within the Profibus DP card, the FieldServer can access data from two distinct buffers. The Input buffer is the data that is sent from the slave to master. The Output buffer is the data sent from the master to the slave. Each Map Descriptor specifies which one of these buffers to access in the card.
