IO Alarm

Switches a digital output, when one or more State-Channels are set. This controller can be used to signal alarms. This controller is used to check for the State-Channels which are boolean type, which typically represents the error channels. A specific configured digital output channel can be signaled based on the configured input State-Channels(one more channels).

Configuration

  • Component-ID Unique ID of this Component (id), e.g. "ctrlIoAlarm0", "ctrlIoAlarm1"

  • Alias Human-readable name of this Component; defaults to Component-ID (alias)

  • Input Channels Addresses of the input State-Channels (inputChannelAddress), This is a array of input state channels.

  • Output Channel Channel address of the Digital Output that should be switched (outputChannelAddress)

Multiple instances can be created in "Apache felix" during the configuration for each Output channel signal.

Example Configuration

  • Component-ID : ctrlIoAlarm0

  • Alias : myIoAlarm

  • Input Channels : [ess0/State15, ess0/State33, ess0/State43]

  • Output Channel : io0/Relay1

ess0/State15 - represents the State15 channels of the ESS0, io0/relay1 = represents the relay 1 of the KM tronic relay board.

The above example configuration describes, if any of the configured three input channels is set to "True" then a signal "True" is sent to output channel, else the "False" signal is sent to output channel.
