Dear Guest.

Profibus DP .GSD Files

The Profibus DP protocol specifies that the device manufacturer provide a text file for every Profibus slave device. Generally, this file has a .GSD extension although language-specific versions (.GSG for German, .GSE for English, .GSF for French, and so on) might be available. This file contains the maximum number of Profibus modules in the device configuration, the parameter values specified for each module, and the number of input and output bytes in the data exchange messages. The parameter values customize the device behavior. The Device Definition also contains the supported baud rates, timing information, fail safe behavior, and diagnostic error codes. The Device Definition is added to the DeltaV Library to add a new Profibus Device to the DeltaV system. The Device Description describes how the device communicates, it does not describe the data semantics or data type. For each Profibus module the user configures signals that describe the I/O that the Slot (Profibus module) provides to the DeltaV system.

Regards

Modbus = Mod(icon) + bus

Modicon is the original manufacturer who invented the protocol for use with their PLC's.

bus= pathway for data transfer
