Description:
|
||
|
|
Program sensor type for threshold detector inputs.
|
||
|
|
Could be either "GND-Open" or "Supply-Open" mode. Y is a
|
||
|
|
threshold detector input channel. Channels 0..7, 8..15, 16..23
|
||
|
|
and 24..31 has common sensor types.

Description:
|
||
|
|
Channel Y low voltage threshold. If sensor input voltage goes lower then
|
||
|
|
this value then the threshold falling event is pushed.
|
||
|
|
Depending on in_voltageY_sensing_mode the low voltage threshold
|
||
|
|
is separately set for "GND-Open" and "Supply-Open" modes.
|
||
|
|
Channels 0..31 have common low threshold values, but could have different
|
||
|
|
sensing_modes.
|
||
|
|
The low voltage threshold range is between 2..21V.
|
||
|
|
Hysteresis between low and high thresholds can not be lower then 2 and
|
||
|
|
can not be odd.
|
||
|
|
If falling threshold results hysteresis to odd value then rising
|
||
|
|
threshold is automatically subtracted by one.

Description:
|
||
|
|
Channel Y high voltage threshold. If sensor input voltage goes higher then
|
||
|
|
this value then the threshold rising event is pushed.
|
||
|
|
Depending on in_voltageY_sensing_mode the high voltage threshold
|
||
|
|
is separately set for "GND-Open" and "Supply-Open" modes.
|
||
|
|
Channels 0..31 have common high threshold values, but could have different
|
||
|
|
sensing_modes.
|
||
|
|
The high voltage threshold range is between 3..22V.
|
||
|
|
Hysteresis between low and high thresholds can not be lower then 2 and
|
||
|
|
can not be odd.
|
||
|
|
If rising threshold results hysteresis to odd value then falling
|
||
|
|
threshold is automatically appended by one.
