IEC 104 Protocol stack configuration
The IEC 104 protocol stack configuration specifies communication parameters and is a collection of entries containing information about OSI Transport and OSI Application layers objects.
Each entry is comprised of attributes that describe the object. All the configuration data are structured using JSON.
Each entry shall be mapped with the corresponding configuration function in the chosen implementation protocol library.
