i2c (FB) ¶ FUNCTION_BLOCK i2c This function block is the base class for I²C devices controlled via the I²C device /dev/i2c-1 . It is meant to be extended by other function blocks that overload the body and the following methods/properties and replace it with their specific implementation, always including a call of the base implementation with super^.<MethodName>() : body (general handling, start-up) AfterReadInputs (reading input data) BeforeWriteOutputs (writing output data) Initialize [optional] (used to read parameters from the configuration) Operational [optional] (used to signal the status of the device) The body of this FB is called by the methods AfterReadInputs and BeforeWriteOutputs , where _xAfterReadInputs indicates the caller. Use _iState to control your statemachine. A value of 10 by default indicates that the device is operational. Do not forget to call the base implementation with super^() , where the diagnosis indicators are set according to the Operational property.
