String80 Description   Optional description.
UInt32 ErrorCount   Error counter, incremented for every failed read operation of the card.
When the error counter reaches ErrorSoftLimit, a message is sent to the console log.
When it reaches ErrorHardLimit, all IO handling is aborted.
UInt32 ErrorSoftLimit   Value of the error counter, when a message is sent to the console log.
UInt32 ErrorHardLimit   Value of the error counter, when all IO handling is aborted.
UInt16 MaxNoOfChannels   Maximum number of channels of the card.
UInt32 RegAddress   QBUS address of the card.
UInt32 SwitchSettings   Settings of the address switch on the board.
The value is filled in when the object is created, calculated
from the current position of the object in the rack. If the
positions is changed the settings can be updated with the SetAddress
method in the popup menu.

The settings are presented with an integer value, and leading zeros
are missing.
