How do I edit the Profibus Configuration Extension?

Editing the Profibus configuration extension is a multi-step process that first involves exporting an initial *.CFG file from PLC WorkShop for Modicon – 32 Bit.

To support configuring the Profibus, the following software bundle is required:
Profibus DP Config Pack for CRP 811, Part Number 332SPU83301

The Softing Profibus DP Configurator is used to create a *.CNF file. The SPU931 Profibus Local Configuration Tool combines information from the initial *.CFG and *.CNF files and rewrites a new *.CFG file.

Finally, this rewritten *.CFG file is imported back into PLC WorkShop to become part of the configuration extension.

Follow these steps to add or edit the Profibus configuration extension:

1. In PLC WorkShop, select PLC Configuration from the PLC Utilities menu to display the PLC Configuration dialog.
2. Add any 140 CRP 811 00 modules needed in the Traffic Cop (click the Traffic Cop button to access the series of Traffic Cop dialogs).
