    • Constructor Detail

      • BrickletDualRelay

        public BrickletDualRelay​(java.lang.String uid,
                                 IPConnection ipcon)
        Creates an object with the unique device ID \c uid. and adds it to the IP Connection \c ipcon.

      • setState

        public void setState​(boolean relay1,
                             boolean relay2)
                      throws TinkerforgeException
        Sets the state of the relays, *true* means on and *false* means off. For example: (true, false) turns relay 1 on and relay 2 off. If you just want to set one of the relays and don't know the current state of the other relay, you can get the state with getState() or you can use setSelectedState(short, boolean). All running monoflop timers will be aborted if this function is called.
        Throws:
        TinkerforgeException
      • setMonoflop

        public void setMonoflop​(short relay,
                                boolean state,
                                long time)
                         throws TinkerforgeException
        The first parameter can be 1 or 2 (relay 1 or relay 2). The second parameter is the desired state of the relay (*true* means on and *false* means off). The third parameter indicates the time that the relay should hold the state. If this function is called with the parameters (1, true, 1500): Relay 1 will turn on and in 1.5s it will turn off again. A monoflop can be used as a failsafe mechanism. For example: Lets assume you have a RS485 bus and a Dual Relay Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds. The relay will be on all the time. If now the RS485 connection is lost, the relay will turn off in at most two seconds.
        Throws:
        TinkerforgeException
      • setSelectedState

        public void setSelectedState​(short relay,
                                     boolean state)
                              throws TinkerforgeException
        Sets the state of the selected relay (1 or 2), *true* means on and *false* means off. A running monoflop timer for the selected relay will be aborted if this function is called. The other relay remains untouched.
        Throws:
        TinkerforgeException
      • getIdentity

        public Device.Identity getIdentity()
                                    throws TinkerforgeException
        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', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'. The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|
        Specified by:

        Throws:
