SunSpec

The SunSpec library is a helper library for the implementation of a SunSpec complient application. It provides SunSpec specific datatypes with associated type converters and JSON support.

See SunSpec Information Model Specification (SunSpec Alliance Interoperability Specification) - Document #: 12041, Status: Approved, Version 1.9

Datatypes

Standard Data Formats

  • int: signed integer value.
  • uint: unsigned integer value
  • pad: reserved field, used to round a Model to an even number of registers
  • acc: accumulated value, used for ever increasing values that may roll over
  • enum: enumerated value, used for status and state
  • bitfield: a collection of bits, multi-valued alarms or state
  • string: a null terminated or fixed length value
  • ip: internet protocol formatted network address
