IEC61850-9-2: Sampled Values

Prerequisites

This node-type requires libiec61850 (>= 1.3.1).

Implementation

The source code of the node-type is available here: https://github.com/VILLASframework/node/blob/master/lib/nodes/iec61850_sv.cpp

Data-types

Type	Format identifier
boolean	b
int8	o
int16	w
int32	d
int64	g
int8u	O
int16u	W
int32u	D
int64u	G
float32	f
float64	F
enumerated	e
coded_enum	c
octet_string	s
visible_string	S
objectname	n
objectreference	r
timestamp	t
entrytime	e
bitstring	B

Configuration

	object (Input configuration (received by VILLASnode))
	object (Output configuration (sent out by VILLASnode))
interface required	string Name of network interface to/from which this node will publish/subscribe for SV frames.
app_id	integer Default: 16384
dst_address	string Default: "01:0c:cd:01:00:01"
vectorize	integer Default: 1 This setting allows to send multiple samples in a single message to the destination nodes. The value of this setting determines how many samples will be combined into one packet.
	Array of Hook Object (object) or Hook Name (string) (hook_list)
builtin	boolean (Builtin hook functions) Default: true By default, each node and paths has a couple of default hooks attached to them. With this setting the attachment of built-in hooks can be disabled.
