RevPiGateway / RevPiVirtual

Pictures a gateway device. This class inherits from RevPiDevice and provides all the attributes and functions of this class.

This class accommodates all Inputs, Outputs and mems as RevPiIO objects derived from the RevPiIOBase class.

In addition, you can create your own inputs / outputs, which get a specific data format via struct ().  These IOs are RevPiIOStruct object, which are also derived from RevPiIOBase.

class RevPiGateway(RevPiDevice)

NOTE: The same functions are also applicable to the RevPiVirtual:

class RevPiVirtual(RevPiGateway)

The following additional functions are provided:

get_rawbytes()

Specifies the bytes that this device uses.

reg_inp(name, startinp, frm, **kwargs)

Registers a new input with specified formatting.

  • name
    name     Name of the new Input
  • startinp
    startinp     Input name from which to insert
  • frm
    frm     struct() formatting (1 Sign)
  • kwargs
    kwargs     The following optional keyword parameters can be passed:
    • bmk
      bmk       Description for Input
    • bit
      bit       Registers input as bool () at the specified bit in the Byte
    • byteorder
      byteorder Set byteorder “little” (Default) “big”
    • defaultvalue
      defaultvalue       Standardvalue for Input, standard is 0
    • event
      event       Register function for Event Handling
    • as_thread
      as_thread       Executes the event function as a RevPiCallback thread
    • edge
      edge       Event execution at RISING, FALLING or BOTH value Change
reg_out(name, startinp, frm, **kwargs)

Registers a new output with specified formatting.

  • name

    • bmk
      bmk       Description for Output
    • bit
      bit       Registers outputs as bool () at the specified bit in the Byte
    • defaultvalue
      defaultvalue       Default for output, default is 0
    • event
      event       Register function for Event Handling
    • as_thread
