Internal (Actiweb-to-Actiweb)

Internal connections can be used in two modes:

local:

Moves data from datapoint to another within same device. Use this mode by having “local” as DEVICE in examples below.

remote:

TBD

Internal dataSource and dataTargets

Internal datasources and -targets (later just dataurls) consists of multiple parts, just like regular http-urls do. Here is an example of modbusrtu dataSource: actiweb://DEVICE/path%2Fto%2Fpoint?scale=2

Dataurl as a dataSource copies value from path/to/point.pv to this poin’s pv field. DataTarget copies this point’s pv value to path/to/point.pv.

The dataurl can be split into parts which are separated by / character.

protocol

actiweb:// This part tells the Internal module to access this datapoint.

device

DEVICE Use “local” for intra device connections.

path

path%2Fto%2Fpoint URL encoded pointname. Do not use “.fieldname” in the point path, because this module only deals with pv values.

parameters

scale=2 All of the regular Actiweb URL parameters apply to this protocol. Note that dataTarget uses reversed functions and this example would equal scale=0.5 in the target points dataSource.
