DATA FORMAT OF JUDGEMENT WAVEFORM AND WAVE LOG
This section explains the saved data format of waveform log / judgment waveform in wave compare mode.
In the wave compare mode, 1500 points are sampled from the start of measurement, waveform comparison with the
judgment waveform is performed, and wave log is saved. In this product, due to the storage area of data and the
drawing on the screen, waveform comparison is performed by performing the following internal processing.
●Data processing in waveform comparison mode
· In "RefWaveCapture", the measured 1500 points are averaged every 10 points, compressed to 150 points, and saved
as a reference waveform.
· In "CreateCompWave", shift the reference waveform according to the set up / down shift amount and left / right shift
amount, and create 150 upper judgment waveform and lower judgment waveform, respectively.
· In "Wave compare", creates a judgment value of 1500 points by linear interpolate between each point from 150
points of the upper and lower judgment waveforms and executes comparison judgment one point at a time with 1500
points of upper and lower judgment value and 1500 points of measurement data. The saved data is 150 points that
are thinned out data of 1500 measurement data.
●Waveform log storage data
· "OK/NG WaveA/B View" displays 150 judgment waveforms and 150 log data.
●Waveform acquisition data in communication
·
The latest waveform data and waveform log can be read by "Modbus communication".
·
To retrieve the latest data, select the acquisition data at the following address,
54301: "Ach / Bch"
54302: "acquired waveform / upper judgment waveform / lower judgment waveform"
Address: It acquires 150 points for 54311 to 54440 (2 addresses / 1 data).
·
When retrieving the waveform log data, select acquisition data at the following address,
55501: "Ach / Bch"
55502: "Normal log / abnormal log"
55503: "Log No. 1/2/3/4"
55504: "acquired waveform / upper judgment waveform / lower judgment waveform"
Address: Acquire 150 points of data at 55514 to 55812 (2 addresses / 1 data).
