8. Set the LossSoC threshold for a R-Series Powerlink sensor

The following description is an example of changing threshold
LossSoC using SDO objects of a R-Series sensor with Powerlink
interface.

8.1 Hardware setup

In this example the sensor is configured to node ID 1 and connected
to a control system X20IF1082-2, which is mounted to a control
system X20CP3485-1. The screenshot of the hardware setup in
"Automation Studio" by B&R is shown in Fig. 71.

8.2 Defined data types

To implement a state machine, an enumeration type has been defined
that contains all used states (Fig. 72).

Description
This is the initial state in this project.
In this state PLC reads the current
LossSoC threshold from the sensor
and stores it to a local variable.
PLC enters into this state when the
operations of
STATE_READ_INITIAL_VALUE
have been finished. The LossSoC
threshold value is set to the given value.
PLC enters into this state when the
operations of
STATE_WRITE_NEW_VALUE
have been finished. The current LossSoC
threshold value is read by the PLC and
stored to a local variable here.
PLC enters into this state when the
operations of
STATE_READ_CHANGED_VALUE
have been finished.
