CSV export via the context menu of the Stand-Alone DTM generates file with incorrect contents

CSV export via the context menu of the Stand-Alone DTM generates file with incorrect contents. File contains only ";;;;" symbols, inspite of the fact that process data is configured for both Inputs and Outputs. CSV export of the same process data, initiated via the button in Address Table menu of the DTM is with correct contents.

1. Start SYCON.net and place PROFIBUS Slave Stand-Alone DTM on the root line.
2. Configure one module 1 byte IN and one module 1 byte OUT in DTM's menu.
3. Export CSV file via the DTM's context menu - Additional Functions -> Export -> CSV...
