pub struct IndustrialDual020maBricklet { /* private fields */ }

Expand description

Measures two DC currents between 0mA and 20mA (IEC 60381-1)

Implementations

source

pub fn new(
uid: &str,
ip_connection: &IpConnection
) -> IndustrialDual020maBricklet

Creates an object with the unique device ID uid. This object can then be used after the IP Connection ip_connection is connected.

source

pub fn get_response_expected(
&mut self,
fun: IndustrialDual020maBrickletFunction
) -> Result<bool, GetResponseExpectedError>

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by set_response_expected. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

See set_response_expected for the list of function ID constants available for this function.

source

pub fn set_response_expected(
 &mut self,
 fun: IndustrialDual020maBrickletFunction,
 response_expected: bool
) -> Result<(), SetResponseExpectedError>

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

source

pub fn set_response_expected_all(&mut self, response_expected: bool)

Changes the response expected flag for all setter and callback configuration functions of this device at once.

source

pub fn get_current_callback_receiver(
&self
) -> ConvertingCallbackReceiver<CurrentEvent>

This receiver is triggered periodically with the period that is set by Set Current Receiver Period. The parameter is the current of the sensor.

The get_current_callback_receiver receiver is only triggered if the current has changed since the last triggering.

source

pub fn get_current_reached_callback_receiver(
&self
) -> ConvertingCallbackReceiver<CurrentReachedEvent>

This receiver is triggered when the threshold as set by Set Current Receiver Threshold is reached. The parameter is the current of the sensor.

If the threshold keeps being reached, the receiver is triggered periodically with the period as set by Set Debounce Period.

source

pub fn get_current(&self, sensor: u8) -> ConvertingReceiver<i32>

Returns the current of the specified sensor (0 or 1). The value is in nA and between 0nA and 22505322nA (22.5mA).

It is possible to detect if an IEC 60381-1 compatible sensor is connected and if it works probably.

If the returned current is below 4mA, there is likely no sensor connected or the sensor may be defect. If the returned current is over 20mA, there might be a short circuit or the sensor may be defect.

If you want to get the current periodically, it is recommended to use the get_current_callback_receiver receiver and set the period with Set Current Receiver Period.

source

pub fn set_current_callback_period(
 &self,
 sensor: u8,
 period: u32
) -> ConvertingReceiver<()>

Sets the period in ms with which the get_current_callback_receiver receiver is triggered periodically for the given sensor. A value of 0 turns the receiver off.

The get_current_callback_receiver receiver is only triggered if the current has changed since the last triggering.

The default value is 0.

source

pub fn get_current_callback_period(&self, sensor: u8) -> ConvertingReceiver<u32>

Returns the period as set by Set Current Receiver Period.

source

pub fn set_current_callback_threshold(
 &self,
 sensor: u8,
 option: char,
 min: i32,
 max: i32
) -> ConvertingReceiver<()>

Sets the thresholds for the get_current_reached_callback_receiver receiver for the given sensor.

The following options are possible:

Option	Description
‘x’	Receiver is turned off
‘o’	Receiver is triggered when the current is outside the min and max values
‘i’	Receiver is triggered when the current is inside the min and max values
‘<’	Receiver is triggered when the current is smaller than the min value (max is ignored)
‘>’	Receiver is triggered when the current is greater than the min value (max is ignored)
