Tinkerforge::BrickletIndustrialQuadRelayV2 - 4 galvanically isolated solid state relays
This constant is used to identify a Industrial Quad Relay Bricklet 2.0.
The get_identity() subroutine and the CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.
This constant represents the display name of a Industrial Quad Relay Bricklet 2.0.
This constant is used with the register_callback() subroutine to specify the CALLBACK_MONOFLOP_DONE callback.
This constant is used with the get_response_expected(), set_response_expected() and set_response_expected_all() subroutines.
Creates an object with the unique device ID *uid* and adds it to the IP Connection *ipcon*.
Sets the value of all four relays. A value of *true* closes the relay and a value of *false* opens the relay.
Use :func:`Set Selected Value` to only change one relay.
Returns the values as set by :func:`Set Value`.
Configures a monoflop of the specified channel.
The second parameter is the desired value of the specified channel. A *true* means relay closed and a *false* means relay open.
The third parameter indicates the time (in ms) that the channels should hold the value.
If this function is called with the parameters (0, 1, 1500) channel 0 will close and in 1.5s channel 0 will open again
A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and a Industrial Quad Relay Bricklet 2.0 connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and channel 0 closed. Channel 0 will be closed all the time. If now the RS485 connection is lost, then channel 0 will be opened in at most two seconds.
Returns (for the given channel) the current value and the time as set by :func:`Set Monoflop` as well as the remaining time until the value flips.
If the timer is not running currently, the remaining time will be returned as 0.
Sets the output value of the specified channel without affecting the other channels.
Each channel has a corresponding LED. You can turn the LED Off, On or show a heartbeat. You can also set the LED to "Channel Status". In this mode the LED is on if the channel is high and off otherwise.
By default all channel LEDs are configured as "Channel Status".
Returns the Channel LED configuration as set by :func:`Set Channel LED Config`
Returns the error count for the communication between Brick and Bricklet.
The errors are divided into
* ack checksum errors, * message checksum errors, * frameing errors and * overflow errors.
The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.
Sets the bootloader mode and returns the status after the requested mode change was instigated.
You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier und crc are present and correct.
This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.
Returns the current bootloader mode, see :func:`Set Bootloader Mode`.
Sets the firmware pointer for :func:`Write Firmware`. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).
Writes 64 Bytes of firmware at the position as written by :func:`Set Write Firmware Pointer` before. The firmware is written to flash every 4 chunks.
You can only write firmware in bootloader mode.
Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.
You can also turn the LED permanently on/off or show a heartbeat.
If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.
Returns the configuration as set by :func:`Set Status LED Config`
Returns the temperature in °C as measured inside the microcontroller. The value returned is not the ambient temperature!
The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.
Calling this function will reset the Bricklet. All configurations will be lost.
After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!
Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.
We recommend that you use Brick Viewer to change the UID.
Returns the current UID as an integer. Encode as Base58 to get the usual string version.
Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.
The position can be 'a', 'b', 'c' or 'd'.
The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|
