ExSunspec

ExSunSpec lets you quickly define profiles for SunSpec compliant devices.

Installation

If available in Hex, the package can be installed by adding ex_sunspec to your list of dependencies in mix.exs:

def deps do
  [{:ex_sunspec, "~> 0.1.0"}]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/ex_sunspec.

Use

ExSunSpec uses macros to let you define unit profiles with minimal data declaration. Example:

Declare

defmodule Fronius.SpecificModel do
  use ExModbus.SunSpec, 40_000, [100, 101, 121, 133]
end

Usage TCP and RTU

ex_sunspec relies on ex_modbus, which can communicate via TCP or RTU connections. The connection required is inferred based on the start_link parameters. If a host or ip is provided, we assume TCP. If tty & speed are provided, then RTU is configured.

Read Data

{:ok, pid} = Fronius.SpecificModel.start_link {10, 0, 0, 1}
Fronius.mn(pid, 1)
{:ok, "Fronius"}

Write Data

{:ok, pid} = Fronius.SpecificModel.start_link {10, 0, 0, 1}
Fronius.SpecificModel.set_out_pfset(pid, 1, 12)
{:ok, 12}
