Class PDOStorage

java.lang.Object

org.lsst.ccs.subsystems.fcs.common.PDOStorage

All Implemented Interfaces:

Serializable

public class PDOStorage
extends Object
implements Serializable

To store the values returned by a PDO. The PDO request is a way to read all the values returned by a CANopen devices in the same request. For example, if we have an ADC which has 8 physical entries, 8 sensors can be physically connected to this ADC. So to read the value sent by the sensor we need to know the nodeID of the ADC and on which entry the sensor is connected to (inputNB). A PDO request is a CANopen command "sync". The response to a PDO request is a String which is formated like : "ADC1_1=10,ADC1_2=F53B, ...." That means that the sensor connected to the entry 1 of ADC which nodeID is 1, has the value 10. And that the sensor connected to the entry 2 of ADC which nodeID is 1, has the value F53B. All the values are in hexadecimal format. The goal of this class is to provide a method (updatePDOs) to extract the values sent by sensors from this response and to store this values in a hasp map.

Method Detail

updatePDOs

public void updatePDOs(String pdoLine)

update the PDO storage in reading a PDO line response.

Parameters:

pdoLine - something like : "ADC1_1=10,ADC1_2=F53B, ...."

getVarValue

public String getVarValue(String nodeID,
                          String inputNB)

Returns the value stored for a CANopen device identified by its nodeID and for an input number on this CANopen device.

Parameters:

nodeID -

inputNB -

Returns:

setVarValue

public void setVarValue(String nodeID,
                        String inputNB,
                        String varValue)

For the simulation ONLY. This set a new hexa value in the PDO Storage in order to simulate a sensor.

Parameters:

nodeID -

inputNB -

varValue -

toString

public String toString()

Overrides:

toString in class Object
