This value controls the level of detail logged either to the display, or to a file.  The same values are used when registry controlled logging is used ("LogLevel" registry key).
The value of this property is a bit field, being the sum of the following bit values:

Decimal	Hex
1	1	Errors
2	2	Warnings
4	4	Informational Messages
8	8	Detailed Logging
16	10	All DICOM attributes received or read
32	20	All DICOM attributes send or written
64	40	Byte-level data received, except contents of data PDUs
128	80	Byte-level data sent, except contents of data PDUs
256	100	ALL bytes received
512	200	ALL bytes sent

The last two levels should NOT be used when images are being sent or received, as the quality of log data becomes unmanageable, and the system will probably run so slowly that connecting equipment will time-out.
Other bits in the lower word are reserved for Medical Connections’ use or future expansion.
The bits in the high word (65536 upwards) are available for user use – see the DicomGlobal.Log method for more details.
