Brush Condition Monitoring Software Release Notes

Logging: pairing data to logs saved

Modbus: button to re-initialize Modbus ports and error logging

Modbus: variables to keep track of individual sensor errors

UI: ttyS3 to Modbus settings title

UI: temperature history and display to brush details page

UI: temperature display to sensor data window

UI: recent temperatures to sensor data windows

UI: temperature critical fault to settings window

UI: temperature and adjust box sizes

UI: alternate color button to group sensors

Minor fix for logging format

Workaround for a bug that prevents pairing from succeeding. This bug occurs when a bluetooth device is removed from the hash but still exists in the cache.

Reboot system rather than application after successful software update

Bluetooth: spread measurements across entire polling window

UI: update splash and logo art

UI: only display one OK button on system log dump

UI: connect button to clear all brush length warnings functionality to settings window

UI: adjust historical readings to be centered, update configuration labels

UI: refine center of text when drawing custom_button

UI: rectangle buttons

UI: consolidate button to save logs, add Bluetooth logs

UI: button press check for new brush detection

UI: degree symbol from temperature display

Button to disable location

RSSI (Received Signal Strength Indicator), MAC address, battery voltage to Modbus

Two-hour timeout to Antenna Placement mode

Index and numeric location to CSV export

0.6x coefficient to rescale displacement values

Six most recent displacement values to sensor data dialog

Dialog box to system log export

In previous versions of the code, there were four different error types all getting logged under the category "Sensor Malfunction": length error, temperature critical warning, old sensor sample, and a true sensor malfunction. This was misleading for the user and likely caused unnecessary alarm. Code revised to split the Modbus outputs into four different outputs for each error type, so a sensor malfunction will now only be reported if there is a true malfunction.

Dynamically restrict sensor configuration

Allow switching between numeric and alphanumeric indexing

Square corners for sensor display (remove rounding)

Increase polling window to address the loss of data when large number of sensors is paired

Modify both Modbus ports to mimic the settings on the advanced config page

Zoom buttons

Wear rate and temperature from main display

Temperature C/F setting from config

Additional Modbus resource on ttys3 (Port 4)

Preserve and display sensor and brush installation date

Reboot system if no sensor data received for 3x measurement interval

RTU port to ttys2 (Port 3)

RTU server address not being changed

Brush length warnings not being cleared on installation of a new brush

Increase the displacement fault max value to 100.0 mils and increase the button step size from 0.1/0.5 mils to 0.1/1.0 mils

Increase wear rate averaging window to 14 days

Move measurement interval setting to advanced configuration page

UI to flash green on a button press (rather than blue)

Don't display length if magnetic encoder error is reported by BHS

Limit Modbus wear rate reporting to positive values

Modify image and language on pairing screen

Clarify messages on BHS update dialog

Modify wear rate to show one significant digit rather than zero

Converted wear rate to deci-mills in order to preserve data

Modbus now reads deci-mills/day for wear rate, app still displays in mils

To avoid gaps in data during a system being down, remove check for 14 days' worth of data, use all available

Check for a minimum of three days of data and six samples before displaying wear rate

Brush count and move measurement count on brush details page

Historical data from Brush Details page (only display current readings)

Functionality for sensor calibration firmware

Modify zero point on 100% brush length and expand threshold length for calibration trigger

Modify Modbus Registry for proper connections to PI, etc.

Daily restart of BLE scanning

TCP port minimum value to 0 from 2000

Default TCP port to 501 from 57912

Nominal brush length to 74.02 mm (3in – 0.086in)

Full brush limits to –10% and +15% of nominal brush service length (1.5in)

Full brush percentage to display actual percentage if <100%, and round down to 100% if >115%, else sensor error

Low battery count register to Modbus interface

Brush offset calibration

Show battery warning if sensor has less than 30 days left (previously the warning was shown if sensor had no energy to support remaining brush plus one new brush)

Ignore mouse click if screen is off (previously a click on a black screen would still be registered by the application)

Summary registers to Modbus (# of short brushes, near-short brushes, sensor errors and high vibration locations)

Make the SCIP detect a new brush event as: (sensor button pressed) AND (new brush length is (90%–110%)) AND (length changes by at least 50% OR brush length error is set)

Disable wear rate warnings (wear rate outliers are not color coded, always gray—this is top right number on the location icon)

Disable temperature warnings (temperature outliers are not color coded, only if temp is >= 105C it will be shown as orange)

Use fixed wear rate (8mil/day) for predictive battery life estimates (to remove warnings popping up for battery life issues if the measured wear rates are low)

Latch brush length warnings and only clear them if new brush is detected or Clear Warnings button pressed on the Brush Details window (brush length warnings are: short brush (<= 0% remaining length), near-short brush (<= threshold configured in Config window), brush length error (change in brush length by >= 5mm). These warnings persist across app restarts.

Cap displayed brush length at 100%—if actual brush length is in the range [95%, 110%] it will be shown as 100%. Brushes longer than 110% will trigger brush length error.

Update antenna placement RSSI thresholds to –69 and –79 to make antenna placement color coding more helpful

Average last six displacement readings and show averaged value on the location icon
