If you use one of these Flow and Sensor Units, you only need to inform the Sensor Factor. If none of the units available is required, you need to
calculate the User Factor, relating it to the User Unit, Sensor Unit, and
Sensor Factor, and fill in the parameter so that
LogBox-BLE
can correctly
convert the pulses to the unit required. In this case,
LogBox-BLE
will
convert the pulses to the user unit as follows:
●
User Value = (Count)/(Sensor Factor)*(User Factor)
○
It should be considered that the log interval is 1 second. It will not affect the calculation, because internally the
LogBox-BLE
always
considers the log interval.
Example:
Let’s say an application has a PNP-type sensor that computes a produced piece every 30 rising-edge pulses and that the user wants to visualize
the production in pieces per minute.
LogBox-BLE
must have its Digital Input configured with the following parameters:
•
Log Interval: It must be configured in terms of logging the sensor maximum frequency.
•
Input Type: Count
•
Sensor Type: PNP
•
Counting Edge: Rising
•
User Unit: Custom
•
Sensor Factor: 30 (pulses/piece)
•
User Factor: 60 (conversion of pieces per second to pieces per minute)
Thus,
LogBox-BLE
will log, in each log interval, the number of pulses occurring within that period, and every time the data is displayed, it will turn
those pulses into the number of pieces produced per minute (custom unit of the user).
In the same example, let’s say that the log interval is 20 seconds. Thus, if the sensor gives 20 pulses per second, the
LogBox-BLE
will register 400
pulses per range, displaying to the user 40 pieces per minute (((20 pulses/s)/(30 pulses/piece)) * 60 (1 min) = 40).
6.2.2
EVENT LOG
If the digital input is configured for Event Log, each selected border will cause a log in the memory, informing the event and the instant the event
occurred. This log will not be synchronized with the periodic logs, but will also respect the logs beginning and end mode. Events will be logged after
the configured
debounce
time expires. Thus, events will be logged with the
debounce
time delay.
LogBox-BLE
can log up to 10 events within 1
second.
6.2.3
LOG CONTROL
You can use the digital input to start and/or pause the logs of the other input channels. Once configured as Log Control, each border selected will
start or stop the process of in-memory logs. As in the Event Log mode, detected events will only act after the configured
debounce
time expires.
Thus, the start/pause of the logs will be performed with the
debounce
time delay.
