SKF Multilog IMx firmware version 4.1

The SKF Multilog IMx firmware version 4.1 supports more functionality in SKF @ptitude Observer and SKF @ptitude Analyst. This firmware is available for SKF Multilog IMx-C, IMx-P, IMx-S, IMx-W, IMx-B and IMx-M.
Features and functionality of v4.1
The features of this version 4.1 firmware include:
  • Support non-zero default process value
  • Global simultaneous parameters sent together with spectra/time waveforms
  • Spectra window sent also with time waveform (for post processing purposes)
  • Modbus simple heartbeat counter in register 28
  • SCL uses cable check measurement when vibration not measured
  • SCL offset calibration configurable on the combination point itself
  • Vibration points are sampled also during cable fault
  • Live vibration trend has non-zeroed values when cable fault
  • Live spectra/time waveforms possible also when cable fault and out of range
  • Status "no alarm levels checked" for unused vibration components
  • Vector alarm as min/max amplitude/phase "pie" sector (in addition to circle)
  • Sector alarms with low level only is now possible (no phase check)
  • NTP server address can be configured separately from normal server
  • NTP synchronizes from local subnet without server connection wait
  • Server can be configured with DNS name instead of numerical IP address
  • Dynamic alarm level controllable by parameter less than zero
  • Harmonic analysis for order-tracked points
  • Separate resolution in transient and normal state
  • Separate storage intervals for normal and alarm state
  • Alarm group minimum time to rearm trigger selectable (default still 30 s)
  • Alarm storage intervals can be activated for all points in the alarm group
  • Additional storage when trend value changes enough from last stored value
  • Selection of which transient group states a point is active
  • Data sampled by one vibration point can be used by another point
  • Pre/post alarm data storage
  • Time waveform includes bias information (when config version >=9.1)
  • Averaging supported for time waveform analysis points
  • IMx-P adjusted charge detection threshold for wider charger compatibility

Error handling and performance improvements:

  • Cleaner/shorter/more configuration error printouts
  • Detected configuration errors stored in buffer
  • Reduced RAM data buffering when server is not available
  • Fail-over server support
  • DHCP client error printed every minute instead of server connect error
  • Faster initial server connection when using DHCP
  • Prevents download of incompatible firmware vs system configuration
  •  Data buffer added to avoid waiting for slow flash writes
  •  Optimized signal processing for faster measurement rates
  • Optimized response time when storing time waveforms only
IMx-M 3.1 support:
  • IMx-M protection status request
  • IMx-M protection gap status inherited on virtual analogue ch 17-32
  • IMx-M protection combined channel data on virtual analogue ch 33-40
  • IMx-M protection speed point status inherited from virtual digital ch 1-8
  • IMx-M protection trip multiply flag
  • Maintenance mode event
  • Maintenance mode reset timeout 60 seconds without trigger
  • Maintenance mode disables recording of measurement data
  • Maintenance mode stops server connection, listens for incoming connection
  • Client connection possible which does not require firmware download
  • Client connection keeps retriggering maintenance mode
  • TCP connect timeout lowered to 30 seconds (previously 75)
  • IMx-M PRM can send maintenance mode trigger
  • IMx-M PRM generated events discarded in maintenance mode
  • IMx-M PRM receives current IP address for display
  • IMx-M PRM unavailable event timeout depending on disarm (2 or 300 seconds)
  • IMx-M PRM overall can not be used as vibration overall
  • IMx-M CMM/PRM names in printouts

SKF @ptitude monitoring suite compatibility:

  • Required for SKF @ptitude Observer 10.0, Still supports down to 7.0 (possible limitations)
  • SKF @ptitude Analyst 2013 Edition maintenance release 2 (MR2B)
