PROFIBUS Master configuration page 'Bus Parameters': Data Control Time might equal 6* Watchdog Control Time

If the user configures a 'Data Control Time' lower than 6* 'Watchdog Control Time', the displayed error message box will state "Data Control Time invalid. Data Control Time must be greater than 6*Watchdog Control Time!". This message is not correct because the 'Data Control Time' is allowed to be equal to 6* 'Watchdog Control Time'.

The message text could be extended to "Data Control Time invalid. Data Control Time must be greater than or equal to 6*Watchdog Control Time!"
