USINT 2 - - Enumeration:
0 = No sync support
1 = Low quality
2 = High quality
3-255 = (reserved)
Controller firmware only enumerated parameter (does not go to the drive) which
reflects the time synchronization capability of the device.
• No Sync: This enumeration indicates that the device does not support CIP
Sync time synchronization and therefore cannot interpret or generate time
stamps.
• Low Quality: This enumeration indicates that the device has a low quality
implementation of CIP Sync time synchronization protocol. Latency
associated with the software time sync algorithm limits time stamp accuracy
to no better than 10 microseconds (µsec). Fine interpolation is not
recommended for this time sync implementation. Low Quality time
synchronization is sufficient for Fault and Alarm event logging.
• High Quality: This enumeration indicates that the device has a high quality
implementation of CIP Sync time synchronization protocol resulting in
very accurate time stamping (better than 10 µsec). High Quality time
synchronization is appropriate for fine interpolation and registration
functionality.
