Bemerkung

Die openHAB-Dokumentation ist nur auf Englisch verfügbar.

Warnung

The openHAB bindings are still in beta, but the development was stopped.

This is the description of the openHAB API bindings for the Industrial Dual AC Relay Bricklet. General information and technical specifications for the Industrial Dual AC Relay Bricklet are summarized in its hardware description.

An installation guide for the openHAB API bindings is part of their general description.

Actions

Actions can be used in rules by creating an action object. All actions return a Map<String, Object>. Returned values can be accessed by name, sometimes the type deduction needs some hints, as shown below:

val actions = getActions("tinkerforge", "tinkerforge:brickletindustrialdualacrelay:[UID]")
val hwVersion = actions.brickletIndustrialDualACRelayGetIdentity().get("hardwareVersion") as short[]
logInfo("Example", "Hardware version: " + hwVersion.get(0) + "." + hwVersion.get(1) + "." + hwVersion.get(2))

Basic Actions

brickletIndustrialDualACRelaySetValue(boolean channel0, boolean channel1)
Parameters:
  • channel0 – Type: boolean, Default: false
  • channel1 – Type: boolean, Default: false

Sets the state of the relays, true means on and false means off. For example: (true, false) turns relay 0 on and relay 1 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 Relay 0 or you can use Relay 0.

All running monoflop timers will be aborted if this function is called.

brickletIndustrialDualACRelayGetValue()
Return Map:
  • channel0 – Type: boolean, Default: false
  • channel1 – Type: boolean, Default: false

Returns the state of the relays, true means on and false means off.

Advanced Actions

brickletIndustrialDualACRelaySetSelectedValue(int channel, boolean value)
Parameters:
  • channel – Type: int, Range: [0 to 1]
  • value – Type: boolean

Sets the state of the selected relay, 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.

brickletIndustrialDualACRelaySetMonoflop(int channel, boolean value, long time)
Parameters:
  • channel – Type: int, Range: [0 to 1]
  • value – Type: boolean
  • time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

The first parameter can be 0 or 1 (relay 0 or relay 1). 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 Industrial Dual AC 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.

brickletIndustrialDualACRelayGetMonoflop(int channel)
Parameters:
  • channel – Type: int, Range: [0 to 1]
Return Map:
  • value – Type: boolean
  • time – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]
  • timeRemaining – Type: long, Unit: 1 ms, Range: [0 to 232 - 1]

Returns (for the given relay) the current state and the time as set by Monoflop Relay 0 as well as the remaining time until the state flips.

If the timer is not running currently, the remaining time will be returned as 0.

brickletIndustrialDualACRelayGetChipTemperature()
Return Map:
  • temperature – Type: int, Unit: 1 °C, Range: [-215 to 215 - 1]

Returns the temperature 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.

brickletIndustrialDualACRelayGetStatusLEDConfig()
Return Map:
  • config – Type: int, Range: See constants, Default: 3

Returns the configuration as set by the thing configuration

The following constants are available for this function:

For config:

  • val STATUS_LED_CONFIG_OFF = 0
  • val STATUS_LED_CONFIG_ON = 1
  • val STATUS_LED_CONFIG_SHOW_HEARTBEAT = 2
  • val STATUS_LED_CONFIG_SHOW_STATUS = 3
brickletIndustrialDualACRelayGetSPITFPErrorCount()
Return Map:
  • errorCountAckChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountMessageChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountFrame – Type: long, Range: [0 to 232 - 1]
  • errorCountOverflow – Type: long, Range: [0 to 232 - 1]

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

  • ACK checksum errors,
  • message checksum errors,
  • framing 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.

brickletIndustrialDualACRelayReset()

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!

brickletIndustrialDualACRelayGetIdentity()
Return Map:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char, Range: ['a' to 'h', 'z']
  • hardwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • firmwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • deviceIdentifier – Type: int, Range: [0 to 216 - 1]

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 Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. 

Internal Actions

brickletIndustrialDualACRelayReadUID()
Return Map:
  • uid – Type: long, Range: [0 to 232 - 1]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.
