BAOS SDK v2  1.0.1
An SDK providing access to IP-BAOS devices through BAOS binary protocol version 2.x
SetDatapointValue.cpp

This sample shows how to set datapoint values via the connection API

Datapoint

Usage:

SetDatapointValue <ip_address>
// e.g.:
SetDatapointValue 10.0.0.102

Pre-condition: It assumes that the following datapoints are configured:

|---------|-----------------|-----------------------------|-------------|---------------|
| Number  |  DPT            |  Name                       |  SizeInBit  |  Flags        |
|         |                 |                             |             | C R W T U I   |
|---------|-----------------|-----------------------------|-------------|---------------|
|    1    | DPT 01 - 1 bit  | Actuator A - Switch         | 1           | C - W - - -   |
|---------|-----------------|-----------------------------|-------------|---------------|
|    2    | DPT 01 - 1 bit  | Actuator A - State          | 1           | C R - T - -   |
|---------|-----------------|-----------------------------|-------------|---------------|
|    3    | DPT 01 - 1 bit  | Actuator B - Switch         | 1           | C - W - - -   |
|---------|-----------------|-----------------------------|-------------|---------------|
|    4    | DPT 01 - 1 bit  | Actuator B - State          | 1           | C R - T - -   |
|---------|-----------------|-----------------------------|-------------|---------------|
Note
Another possibility is via the device API.
