IEC 61850 is a hierarchical data structure. Each device has a number of Logical Nodes. Each of these Logical Nodes have zero or more variables, objects an/or datasets. Variables and Objects are tightly coupled. Objects can essentially ignored (AFAICT) as they are just the storage locations of the Variables. Datasets are convenient lists of Variables. The automated logging of this plugin revolves around Datasets. In order to discover all attributes, run a discover as follows. The arguments are discussed below.

iec61850_ardexa discover 10.38.240.20 /tmp/iec_auth variables

Authentication is a single "authentication string". There is no username, but some providers abuse the authentication string and embed a username anyway. For example: -user#"admin" -pass#"password_here"

Arguments

Arguments are as follows:

• endpoint. This is either a serial device like /dev/ttyS0 or an IP or DNS like 192.168.1.15 parameter, ie; the serial connection.

• auth file location. This contains the authentication string

• type. This is the type of object to read and can be 1 of the following: datasets, files, variables
